Several Unaddressed Gotenna Mesh / Twilio Emergency SOS Shortcomings

Emergency communications are important… maybe not today. Hopefully not tomorrow. But disaster strikes when we least expect it. If we are wholly unprepared… it may hurt you and those you love.


After a solid year of earnestly trying to iron out the wrinkles with Gotenna, it’s only prudent to look at other options for when the towers fall.  Gotenna has great potential, and if they don’t screw it all up, they may have a great product soon.  However, in my humble opinion, it’s still only half-baked.  The central premise of Gotenna mesh is that it has fatfingered emergency communications and amateur / ham radio / CB / Murs / FRS / GMRS walkie talkies … by marrying with smartphones…making it easy for anyone to use without any worry of navigating the maelstrom of treacherous federal legislation that is FCC and DOC/DHS export restrictions.  Gotenna automatically determines your location based on gps and configures what frequencies and power settings you are allowed to use without any license needed whatsoever, wherever in the world you are.  Not only that, but Gotenna ensures that when you use it, you can’t accidentally interfere with any preexisting official or emergency communications channels ANYWHERE in the world.  And, most importantly, Gotenna wholly obviates the need to learn anything about electrical engineering, radio theory, or complicated vcr-like radio settings screens.  Any idiot can use Gotenna because it works on your phone and holds your hand guiding you the whole way and helping you ignore settings you don’t need.  It’s the iphone of amateur radio / emergency communications.  In a lot of ways, it’s the BaoFeng of radios – with a little searching, you can get one for less than $50.  It’s so cheap that there’s no entry barrier for new users.  But yet, it’s an American company with solid quality control and built here in the Americas. Not likely to have Chinese backdoors, user manuals exclusively in Chinese, or their notorious quality control 😉  … and Gotenna is wholly legal to toss in your suitcase and take anywhere in the world.  It uses Australian open-source encryption, Bouncy Castle, so there’s no worry of violating federal or international law without an export/import license.

However, there are some outstanding issues and inherent flaws in the Gotenna Mesh and Gotenna Pro devices which stop them from being widely adopted… yet, and may make it dangerous to deploy or rely on.

1. Gotenna Mesh offers Emergency Chat and Emergency SOS features, along with a headless mode that doesn’t even require a working phone to call for help.  Loved ones can click the power button five times and trigger the SOS beacon with a preprogrammed emergency message (e.g., name, address, blood type, backup contacts, phone number, radio channel & callsign…)  However, there is NO CONSPICUOUS warning that the Gotenna device does NOT have a gps chip.  So any gps location being transmitted in this SOS Emergency broadcast mode MAY NOT HAVE ACCURATE LOCATION of the call for help.  That’s kind of dangerous.

2. Gotenna Mesh offers SMS Relay mode (basically, if you have no service, this allows you to send simple cellphone text messages and gps location across the internet to anyone in the world even if you don’t have any internet or cellsignal, by way of the Gotenna radio, itself, through ANY other Gotenna user within tens of miles of range* who does have a working signal.  HOWEVER, again, there is no conspicuous warning to users, that there are some serious flaws with this text relay.  For example, this feature ONLY SENDS ONE WAY messages – there is NO WAY to receive any response to your message.

3. Another huge flaw is that Gotenna nowhere conspicuously warns their users that these SMS text messages, or even their Emergency SOS, or Emergency Chat features are not and cannot ever be delivered to 911, 999, Geos, or ANY emergency Call Center (PSPAPs).  Literally cannot be sent.  It violates the sms relay service (Twilio) that Gotenna uses to deliver these messages across the internet.  For some reason, Gotenna will not answer questions about why they won’t consider using another sms relay provider, like, e.g., / @Bandwidth that gladly offer 911 Text Relay services (#Text911).

4. Yet another gamestopper is that inasmuch as Gotenna Mesh CANNOT operate in bidirectional mode in text sms (or even provide unidirectional message to 911 services)… then you are limited from communicating effectively, in an emergency, with anyone who does not have a Gotenna Mesh device.  The problem with this, is that Gotenna, Inc. markets and sells an incompatible product, the Gotenna PRO device, to first-responders- which does not work whatsoever with Gotenna Mesh devices.  The device first responders have cannot ever receive, or even locate, a Gotenna Mesh device held by survivors – even in Emergency mode.

In sum, a loved one could easily trigger the Emergency SOS mode thinking that their message will ultimately be delivered to someone who can help.  However, (1) even if their message gets through, the other party may have no idea where they are – and can’t ask for clarification; (2) and even if it fails they may never get a warning that it didn’t go through; (3) it will never even attempt to deliver the message to 911; and (4) first-responders nearby cannot receive the message with the devices they are likely to carry.

So, my recommendation, is to get you and your loved-ones Ham Radio certified.  You can get your Technician class license in under 8 hours of study on for free.  You only need to pay about $15 to take the test. It’s only 35 questions drawn from a pool of 423 questions.  You only need to get 26 right.  Especially if you are a geek or electrically disposed, at all, most of the questions are common-sense.  @Hoshnasi has some really great recommendations on his youtube channel and walks you through the test, what radio to buy (e.g., BaoFeng UV-5r ($19), Yaesu FT-60 ($149ish), and how to avoid interfering with emergency or official communications.

If you are a geek, get yourself a usb SDR like RTL-SDR for about $10 on ebay with an antenna that will work with your laptop or home pc.  If you are a mobile geek, get a USB-C to USB-A (fullsize female) host dongle at walmart or online or a micro-USB on the go (OTG) to USB-A for use with your android tablet or phone.  The cool thing is that you can pickup ANY frequency, ANY channel FM/AM/NOAA/FRS/GMRS/MURS/ Ham UHF/VHF/ marine, air, police, fire, ems… with free software like SDR # or HDSDR.

If you are really cool, check out products like Mobilinkd or a wired modem, or even just 3.5 and 2.5mm cables to marry your smartphone/tablet/pc with your ham radio for advanced features like APRS for two way, long range, digital/analog tactical communications with automated GPS location reporting.

Nothing can prepare you like becoming familiar with what’s already out there- how to listen and how to ask for help when you really need it to help you, your loved ones, and neighbors in your community.  Once you are all setup, take a look at volunteering with groups like ARES.





A Puerto Rican Standoff…

CALL FIRST IF YOU CAN; text911 if you can’t

Oftentimes, when it’s most needed, people are unable to call 911.  Wouldn’t it be nice if there was a way to get a message to 911 when you just can’t call?

Luckily, alternative measures to reach out for help are starting to flourish.  Apple  iphones and iwatches offer a five-click SOS feature (which, while relying on voice for the 911 portion, automatically fires off a text messages with your gps location to trusted friends or family).  Samsung offers a three-click SOS feature on smartwatches and phones like the S9.  Likewise, Gotenna, a communications device primarily for offgrid hikers, that works over long-range radio even when there’s no coverage available, also offers the 5-click SOS beacon to anyone within radio range.  Yet none of these products offer a way to send a message with your location quickly and easily  to 911 and let you get back to actually surviving until they arrive.  None of these services offer the ability to send a text to 911.  Why is this?

After a disaster scenario, the need to get a quick message out to 911 is all the more important.  Cellphone towers and 911 call centers may be overwhelmed with voice calls to loved ones and millions of attempts to post status updates to facebook or youtube.

A voice call to 911 may not always be possible.  Realtime two-way voice connection to 911 requires a pretty substantial amount of emergency resources bandwidth- in terms of at least: (1) cellphone to tower; (2) backhaul to 911 PSAPs; (3) operator manpower to answer, assess, triage, and route to appropriate first responders, not to mention the first responder resources to actually effect help.

In severe disaster scenarios all 3 of the above limited emergency resources can be drawn very thin and cascading failures can ripple out through the community.

Text 911 (which could help get messages out while simultaneously reducing the burden on these 3 limited emergency resources needed for traditional calls to 911 call centers) has not been fully implemented across the nation yet- in spite of an FCC mandate for it to be operational nationwide by 2014.  However, some increasingly disaster-prone places have fully implemented this service — some having had it for several years. Notably, Puerto Rico has had text911 since 2014 in all 78 municipalities, Los Angeles, DC, Houston, Phoenix, San Antonio, Dallas, Denver, Austin, Jacksonville, Columbus, Indianapolis, Kansas City, San Bernardino, … with NYC and Chicago soon to be added to the list, which goes on and on. It may not yet be ubiquitous. But we are talking TENS OF MILLIONS of people in at least 6 of the 10 most populous cities in the U.S. and several whole states have blanket coverage including Indiana, Vermont, Connecticut, New Hampshire, Maine, Delaware, and New Jersey, with Florida, North Carolina, Kansas, and Iowa set to join by year’s end.

CALL FIRST, and if you can’t, if you are deaf, hearing impaired, if you are in a domestic violence situation, if you are in the trunk of a car being kidnapped, if the celltowers are saturated with calls, if you don’t have reception, if your battery is about to die… countless situations could benefit from the use of text to 911 services.  However, due to red tape, service providers, like e.g., Twilio — the leading cloud-based text and voice provider squarely refuses to let ANY of their customers use this text911 because it violates their terms of service and acceptable use policy.

After hurricanes Irma and Maria destroyed satellite uplinks, smashed celltowers, radio repeaters, and power generation and delivery, made spaghetti out of telephone lines- the only operable communications platform available was Gotenna Mesh. It was uniquely attractive because it didn’t require telecommunications uplinks, didn’t require internet, cellphone, radio repeater nets, generators, FCC licensure, or the infrastructure links likely to fail. It was its own repeater network, it sipped its own battery power, it could be charged from a cellphone charger or a tiny solar panel and yet still give miles of range. When any single node in a Gotenna mesh had a signal, messages from anyone could be backhauled out to anyone in the world — anyone, including Puerto Rico or Houston’s text 911 system.

Gotenna is uniquely effective because it bypasses the weakest links in the telecommunications chain AND it addresses all 3 of the scarce emergency resources most likely to experience cascading failures: (1) using Gotenna to deliver gps-tagged text messages (a few hundred bytes in a single latency-tolerant data envelope) significantly frees up celltower voice bandwidth (tens of kilobytes per second per user); (2) frees up backhaul from the celltower to the 911; (3) frees up operators to respond to voice calls and allows a level of automation, triage, AI agent response, de-duplication, and gps authentication; and (4) where first responders are in the area (within up to six hops, where each hop can be between 1 and 62 miles) the first responders can respond directly to the request for help without any intervening infrastructure (in fact, the first responders automatically and without any degradation to their Gotenna become part of the infrastructure, filling in gaps as they search and rescue) — yet further, those with Gotenna devices often become volunteer responders, helping their neighbors and obviating the very need for outside assistance, freeing scarce first responder resources. Gotennas develop communities.

The only thing standing in our way, at least in Puerto Rico and Houston, and for tens of millions of other Americans, are provider’s like Twilio’s acceptable use policy. Perhaps they’ll reconsider- or perhaps Gotenna will consider another text relay provider that does allow text messages to be delivered to 911 call centers, like, e.g., Bandwidth or others? Lead, follow, or get the hell out of our way. It may not be as easy as flipping a switch… but it’s an endeavor worth making with tens of millions of Americans in areas who could benefit. Is it a silver bullet? No, emphatically no… but it gives a fighting chance where Twilio, in stark contrast, is content to fail us by never even trying.

“…who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”

Can we at least try?

Here’s a crazy idea… Twilio may not allow this on their text relay, but they seem to allow it on their elastic sip trunking, and they have an option to pre-define an emergency location. If there’s no other way to proceed, could Twilio servers receive the text911 message, run text and gps to voice, and deliver the message via the voip approach to traditional 911 voice PSAP centers? This would obviate their concerns about non-ubiquitous text911 service and sidestep the AUP for text relay.

2018 Jackasses In Tech Awards

This year, we honor tech companies and government agencies who have firmly put the “i” in stupid, and their executives who truly earned their C-level officer status.  In no particular order, here are the entities who have shown time-and-again that they are willing to put profits over lives of their fellow Americans.


1 Winner, Winner, Chickentofu dinner.

Twilio – Jeff Lawson, CEO @jeffiel

Twilio offers a number of voice and text over IP services. They provide text message relay services, even with emojis, for any messages whatsoever about any trivial thing for their customers.  Especially marketing and robotexting services.  However, when it comes to messages which seek help, are related to an emergency, or which seek to connect with 911 or emergency PSAP call centers, they childishly insist that this violates their terms of service (TOS) and Acceptable Use Policy (AUP).  Even in areas where #text911 is fully functional like Puerto Rico- in all 78 municipalities, Twilio would rather cling to their AUPs, TOS, and ROIs… even if it means we’ll be wishing 3000 Puerto Ricans RIPs.  Twilio RT: Use our product, unless you really need it.

Twilio, is proud to be striving towards a 50% female employee statistic. Fun fact, nearly half of the survivors in Puerto Rico are women… but when it comes to a service like text 911 which is invaluable in helping women in domestic abuse situations, they’d rather the abuse continue than allow their service to be used to get abused women help – even in disaster areas like Puerto Rico where women are all the more likely to return to an abusive home.

I tried to let them know there was a problem… but… apparently Twilio doesn’t have access to Twitter, Instagram, Email, Facebook, or projector vision… Hell I even had a 10foot banner installed outside their Silicon Valley HQ.  They KNOW… they just don’t care.  I emailed Jeff to let him know that he won this year’s Jackass Of The Year Award… no comment yet.twilio

2. BridgeFy – Jorge Rios aka Ribs @JorgeRibs @BridgeFy

BridgeFy provides an offline text messaging program that uses advanced peer to peer (p2p) adhoc wireless networking to deliver messages in a community- device to device.  When cell towers fall or when reporters, activists, whistleblowers need to communicate off the grid, BridgeFy provides this service without needing any infrastructure, nothing except your phone or tablet device.  This is particularly useful in disaster areas like Mexico City after the earthquake, in Puerto Rico after the hurricanes when cell towers are down, power is out, wifi is down, and all other communications means have failed.

However, before survivors can use this application, they must each download and register a 10 Megabyte install file, have a working cellphone number for verification and/or working data services.  The last thing you want during a disaster is a plurality of users downloading multi-megabyte files and sending confirmation sig/acks.  Rather than provide the install file themselves, luckily 3rd parties have made available the BridgeFy .apk install file for offline sharing (e.g. memorystick, card, hotspot fileshare…) and installation in a disaster area – however, the emergency offline communications application, while disingenuously offering the ability to skip the registration/verification step, actually requires working cellular, text, phone and/or wifi data WTF!?


The very first thing that generally happens after a disaster like the Mexico City earthquake or the Puerto Rico hurricanes, is that the power goes out and the wifi goes down, followed by the celltowers being saturated with calls and messages which quickly results in a failure of LTE, 3g, data, and text messaging services and melts the backup batteries and diesel runs out.  To compound this problem, people of limited means, like many of those in disaster areas may not even have a working cell-phone subscription to begin with – this is precisely why the FCC requires that all phones, even those without a simcard be able to call/text 911 – this is why we don’t put locks or chains on emergency exits.

BridgeFy, for some reason, feels that survivors who truly need disaster communications should be required to have an operable cell-phone subscription and sim card, with working cellular towers, and/or working wifi before they can use their product – whose sole reason for existence is communications when there are no other avenues available.  Further, BridgeFy feels that for reporters, whistleblowers, and activists who want to use their product for off the grid communications, they must first use that very grid they seek to avoid by providing their name, email, phonenumber, unique device id, and other personally identifiable information before they can even use their app.


But it gets better. So much better. BridgeFy *actually* has the cojones to troll us with the taunting and inviting roast “Having Trouble? Contact us” hahaha fxck you! Good luck.  When I brought this to their attention, they initially lied about it on twitter, then deleted the tweet and banned my account.  They know. They choose not to unfuck their app to save lives.  I’ve emailed Jorge to let him know he won 3rd place. No comment?

3. GotennaDaniela Perdomo, CEO & Jorge Perdomo, Founder/Inventor #Gotenna #GotennaMesh #GotennaPro

Helpdesk: 1 (302) 540-2246

Gotenna offers the ONLY long-range, emergency communications device that works when all other avenues of communication have failed.  The Gotenna device offers 1-2 miles of range for each hop (up to 62 miles with elevated positioning) and allows for hopping/relaying the message up to six hops away and does not require any classes, testing, or license from the FCC – meaning that anyone, any idiot can use it, and it’s used through the user’s own phone or ipad.  My Mom can operate these devices.  It’s basically just a text and gps chat app.  Gotenna has taken great strides to market and provide both “Emergency” chat and “Emergency SOS beacon” features so that their customers/survivors can send out emergency messages if they need help.  They even offer a simple five-click mode to call for help.

Gotenna also provides a GotennaPlus SMS Relay feature which will relay a text and gps location across any working data signal available – so if, for example, a user sends a message to another user, the message will hop up to 6 times, gotenna device to device (tens of miles without needing ANY infrastructure) and if the message was not able to be delivered, any of those six relaying Gotenna hops can backhaul or relay the message across any signal to get to the internet to deliver a standard text / sms phone message to the intended recipient anywhere in the world, even if they don’t have their own Gotenna device.

This is truly a powerful feature that could be the difference between life and death for many of their users – EXCEPT that Gotenna uses the Twilio text message delivery service
(Estupido Winner Jackass of the year) which forbids the delivery of messages that could save lives, even in domestic abuse situations or disaster areas where there are no other means to get the message out.

Gotenna held a fundraiser that was to deliver up to 300 Gotenna devices to Puerto Rico to form a critical backbone for emergency communications.  As discussed above, Puerto Rico has had a 100% operational text to 911 (#Text911) service for about ten years able to receive emergency sms text messages.  While Gotenna never truly supplied these devices, in spite of the fundraiser being fully funded in November of 2017, there are many 3rd party Gotenna devices in Puerto Rico.  The only thing that stops the “hundreds of thousands of people in the central mountainous regions” from being able to get an emergency text and gps message out to first responders is Gotenna’s adamant refusal to consider another text message relay service (like, e.g., Broadband hint hint) that allows delivery of 911 text messages.


Incredulously, and I mean this seriously strains the bounds of all reason, Gotenna also provides a Gotenna Pro device for first responders and LEOs… however, the Gotenna Pro model is WHOLLY incompatible with the Gotenna Mesh device survivors are likely to have!!! they literally CANNOT talk to one another- so the only people who’s literal only job is to get these messages (first responders, LEOs, and 911) will NEVER get the “emergency” Gotenna message or Gotenna “emergency SOS” beacon (R).


This was painfully evident at Burning Man 2018, when a woman with 3rd degree burns sent a Gotenna emergency message asking for help and the Gotenna network dutifully ignored her request and refused to deliver the message to the fully operational Washoe County text 911 service.  The burnt woman eventually wandered into the desert, in shock, in 107F degree temperatures to seek help the old fashioned way.


I let them know about this “feature” … oddly, for a “communications company,” Gotenna doesn’t appear to use Twitter, Instagram, Email, Phone, Text Messages, or website forum.  Somehow my posts and accounts were accidentally suspended and deleted for a thousand years.  They know.  They just don’t care.  I wrote to congratulate them on their #3 spot in this year’s Jackasses In Tech Awards (JITA 2018) but haven’t heard back from them… No comment?

I wish I could say this was the first time Gotenna had ghosted people… But it gets SO MUCH better.  In spite of taking at least $4000 from a charity meant to provide an emergency communications backbone of GOtenna devices in the hardest hit regions of Puerto Rico for relief efforts (LAST YEAR IN NOVEMBER) … of the 300 that were to be delivered… barely 80 were… and of those 300, LESS THAN 16 were made available to the public.  Was it all GoTenna’s fault? No. Hence, they share this title (Jackass of the Year for JITA 2018) with Javier Malave @JavierMBJG d\b\a variously with noncompetes and ndas with Amazon, PR Reconnects, Starting Point, UPR Eship Network, PR Science and Trust… a serial entrepreneur (with a history in fashion design).  But is Gotenna, a partner in the fundraiser, and the beneficiary of all the goodwill and virtue signalling (no less than 5 links appear to GoTenna’s websites and social media presences adorn the fundraiser page).  Gotenna, as a recipient of MILLIONS of US taxpayer dollars cast shade for the corruption, fraud, and obfuscation of the partnership of joint tortfeasors.  The end result is the same, there is no emergency backup network for “hundreds of thousands of Puerto Ricans” in the hardest hit areas – as the fundraiser called for.  I don’t even know what the fuck the millions in taxpayer funds went to, but apparently not to installing any of these emergency backup units in Puerto Rico?

They know. They just don’t care. And most people are too polite to call them on this bullshit – because we are a society that sweeps abuse under the rug and we look away for mere pennies on the dollar- even when the lives of the most vulnerable in our society are on the line.


4. Beartooth Mesh Network – Jeff Jones, CEO

In spite of the name and their marketing, Beartooth never quite got mesh networking to actually work, so they simply gave up and do not offer this feature  although they still market these features.  In spite of taking millions of dollars in taxpayer money, they refuse to open themselves up to any public oversight, any universal compatibility with other mesh or radio products, refuse to release any source code or even a public audit, and refuse to commit to defending the spirit of the First Amendment guarantees of Free Speech, or private association, let alone the Fourth Amendment guarantees of securities of our letters, communications, and locations from prying governmental eyes.  Beartooth isn’t alone in this regard, as Gotenna is situated exactly the same (having received millions of taxpayer funds and governmental contracts) yet wholly refusing to make any such commitments to protect customer privacy.mesh

5. Sonim devices – Bob Plaschke, CEO

Sonim offers some really solid hardened phone devices (e.g. Sonim Xp8) for first responders where they market the really cool ability to connect modular accessories to the phone to enable additional features…. like Beartooth “mesh” networking, P25 digital radio, ?infrared camera? and the like.  However, in spite of marketing this feature and extolling the benefits, no such modular addons are available, no pricing, no availability is forthcoming and all attempts to get more information fall on deaf ears.  The sick part is that they are charging first responders (taxpayers) $199 for a phone charger for the XP8 and XP5s model devices which don’t seem to offer any special features like being inherently safe or non-incendiary.  So they are compromising the safety of our first-responders while robbing them of precious budgets that could be used for other safety equipment that actually works as advertised.  Sonim does not seem to want to clarify if this charger even offers quick charging, or if it’s merely delivering a paltry 1 amp of charge to the device.  And they ?disabled? FM / Weather radio reception?

sonim huh

6. Verizon –

Wouldn’t it be nice if people’s cell phones could receive emergency alerts even when towers are down? It could decidedly be the difference between life and death if we could provide weather updates to hurricane survivors without celltowers or wifi.  Many phones come with an FM radio chip (and when connected to a headset or aux cable) could receive weather/emergency updates even when all other communications means are inoperable – except that Verizon (and other carriers in a bid to get data for streamed music?) forced many phone manufacturers to lock and/or disable this FM radio feature – forcing it to lay dormant in the phones.  Why would an American company forcefully disable measures for Americans to receive emergency information?  Thankfully, the NextRadio app can force the FM radio chip to unlock in many devices.


7. Samsung –

In pursuit of sexy glass backed phones that totally don’t have a propensity to shatter, Samsung and others have done away with favored customer features like a removable and replaceable battery – features that are very useful in disaster scenarios.  But massive respect for their efforts (unlike Apple) at working with NextRadio to provide emergency backup FM and weather radio on the only devices survivors often have on them when they flee a disaster area.

8. Apple –

While FM radio chips are locked in iphones up to the 6S, the Next Radio app was able to bypass this lock and use the FM radio receiver chip to enable survivors to receive emergency alerts and weather updates.  Apparently, in the newer devices, this feature has been “bravely” removed altogether along with the headphone jack which allowed a quick way for survivors to attach headphones or an aux cable to serve as an antenna.

9. FCC – Ajit Pai – @FCC @AjitPaiFCC

While the FCC steadily erodes privacy and consumer protections – and lashes out at states who seek to provide net neutrality and privacy protections, claiming they violate the dormant commerce clause and infringe on the FCC’s sole federal jurisdiction and enumeration of powers, the FCC and Ajit Pai are content to let state and local authorities drag their feet on #text911 services and telecom providers actively lobby and use their powers to disable FM radio chips.

This PSAP readiness report is PISS POOR… shitbirds in these gray jurisdictions refuse to effect text 911 with the due haste required of a 911 system.  And NO ONE is holding them accountable.  Lives could be saved. Sometimes you can’t always keep a voice connection to 911.  Deaf, domestic violence, natural disasters, … get your A game on PSAPS. Props to Puerto Rico, Indiana, Maine, LA, NH, VT, CONN, NJ.


10. USCG ❤ Prepa

While millions of taxpayer funds have been spent erecting backup solar power on every single structure on Coast Guard bases in Puerto Rico, government lawyers and “top negotiators” allowed a contract with the Puerto Rico Electric Power Authority (Prepa) that actually forbids the US Coast Guard from making any use of the solar power devices.  So, for example, after hurricanes Irma and Maria destroyed the electrical grid, the Coast Guard was contractually obligated to let these thousands of solar panels sit idle, feeding power into a wholly non-existent electrical grid – wasting power that could have been employed for operational readiness, for servicemembers and their families, to save lives, or to avoid wasting countless millions of dollars on scarce diesel or gasoline supplies to keep generators running.  USCG had the temerity to discipline local commanding officers who sought to adapt, improvise, and overcome to harness this power – all while survivors died by the thousands.  “Unsung success” just doesn’t give me confidence that this is being worked on or resolved. I’ll respectfully concur with Admiral McRaven in his no-bullshit, frank “embarassment” assessment. Something is wrong when Commanders and Captains are keelhauled for trying to save lives and ensure operational readiness in the face of the worst natural disaster in cinclant in a hundred years.


11. While there were many other jackasses and shitbirds in the tech world this year, these were my favorites.






Corruption, Disarray, and Red Tape in Puerto Rico : Hard Lessons Learned

I’ve been hesitant to write about my experiences in Puerto Rico. A year having passed, I think there may be important lessons to learn.

The corruption runs deep. The unpreparedness and red tape handicap effective leadership.

A U.S. Coast Guard base in Puerto Rico should have been a shining example of leadership, of innovation, of American can-do spirit. Unfortunately, corrupt lawyers, entrenched monopolies, red tape, and ineffective leadership, at the highest levels, provide a glaring example of a dysfunctional government acting to hamstring first-responders and service-members. Gone are the days of improvising, adapting, and overcoming.

After Hurricanes Irma and Maria tore through Puerto Rico, I saw the absolute devastation. I had just quit my job and left my life in DC behind to fly down and be with my Mother, recently widowed after we lost my father, a US Navy Captain- a real leader with the cojones to lead by example and pragmatism do what’s necessary to effect his command, to protect his people, and to stay mission-ready.

Together, we saw the absolute devastation in Puerto Rico. At the same time, Gotenna had just released Gotenna Mesh, an amazing product, the first and still ONLY off the shelf device that enables inexpensive, permit-free, long range disaster communications even when the towers fall — without any infrastructure whatsoever. We saw a young Puerto Rican volunteer geek climbing destroyed buildings in the carnage of San Juan to place these Gotenna Mesh communications repeaters to enable his people to coordinate and communicate without any other operational infrastructure. He needed power but couldn’t find batteries and couldn’t get solar panels. He needed to rapidly prototype, range test, signal test, and intelligently deploy mesh relay devices. At the same time, a friend told me about a Coast Guard base down there that had thousands of mil-spec hardened solar panels lining every building on base that survived the hurricanes but were feeding power into a broken electrical grid. There was no grid. While the surrounding community was without power (as it turns out for almost a year) these thousands of solar panels sat wholly unused- wasting the power that they generated while thousands around them died without water or power.

A monopolistic Puerto Rico Electrical Power Authority (Prepa) had somehow cajoled / negotiated a deal with the US Coast Guard that forbade any use of these solar panels for self-sufficiency or readiness of the base, our military service-members, or their homes. While there were thousands of these solar panels that survived the storms, there was effectively no electrical grid to feed the charge back into — and the poorly negotiated contract prohibited them from harnessing the power locally — even if it was to keep our warfighters and first-responders ready, even if it was to share this surplus electricity with the neighboring community — even, as it was, that the energy was wholly wasted otherwise and people were dying. What you had was a command structure that saw the acute shortcomings and the gravity of the problem but were paralyzed, effectively handcuffed with red tape. Commendably, the local Commanding Officer sought out Tesla and sought to acquire power-wall devices to allow each and every building to be self-sufficient, to avoid being a drain on generator, diesel, and other scarce resources. The local CO sought to keep his team ready — to avoid waste. Admirable qualities for sure in a commanding officer. Because that’s exactly what a US Military Commanding Officer does. When in command, you command. You lead. That’s the Navy approach, sometimes the regs don’t deal with the problem and you can’t just land the plane, lives are on the line. You do what’s necessary to preserve your operational readiness and lives of Americans.

I arrived, sought to provide a liaison between Tesla and the U.S. Coast Guard to the extent I was able. Over a beer with the CO, XO, Ops Officer, Engineering, Public Works, and others, we discussed a plan to provide for localized inversion, regulation, and battery storage and reclamation systems in microgrids. During our discussions, we discussed my primary motivator for coming down, the Gotenna communications devices. The Coast Guard and Customs and Border Patrol were intrigued. They related to me that the very first thing that they do after every disaster is to do a head-count, to reestablish contact with each and every service-member in theater. Where, as here, the telephone lines were down, the federal radio repeaters were down, the cellphone towers had fallen, the internet and wifi were all down, and as a result, MILLIONS of dollars of helicopter sorties had to be flown to visually confirm the welfare of each and every service-member BEFORE ANY search and rescue missions could be flown.

I, initially had an appointment with the XO, however, was unable to reach him by any means. Even the gate guards at the base were unable to reach him because they are on different radios, different, incompatible frequencies from the Coast Guard personnel. So, I offered them my Gotenna devices. However, at the same time, another storm was brewing, a political firestorm that paralyzed the USCG from acquiring power or communications. The request from USCG to Tesla was seen by the administration as an ethical violation, an impropriety, a solicitation to a private vendor. Red tape and ineffective, cowardly leadership at the highest levels actually rebuked the Commanding Officer in a disaster area for trying to keep his base powered.

At that point USCG was paralyzed. They couldn’t accept the Gotenna emergency communication devices from a “vendor” (as they uncharitably described me — however, I was most decidedly not a vendor, not vested, no commercial motivation, no stock owernship, no vested interest, merely a volunteer, an officer of the Federal and State Courts in pro bono publico service). Their concern would be that if they accepted the devices, this would be exactly analogous to the Tesla situation. Over a home-brewed beer, we tried to creatively explore possible ways to gift these devices, to sell them privately for a $1, to trade them for a beer, to create a purchase order, for me to abandon or lose them outside the gate, or get Government services to purchase them directly from Gotenna and make them available to the base, to get a spouse to purchase them wholly separate from USCG personnel. All avenues failed. While Coast Guard insists that they maintained operational readiness, I can tell you… they, like everyone else, were paralyzed. Their fall-back encrypted comms devices were bulky, power hungry, unfamiliar to users, often forgotten at home or work, wholly incompatible with base security and other agencies and operating in simplex, non-relayed mode (with severely limited range due to the federal repeaters being down). The answer was in my hands.

We had 41 encrypted Gotenna devices that each act as their own repeaters, created with taxpayer funds by In-Q-Tel (IQT) the venture capital arm of the Central Intelligence Agency, with millions invested from DOD, DOJ, DHS, FBI, and other federal agencies being loaned by an FBI-vetted Officer of the Federal Courts. Similarly, they had millions invested in solar panels… but no way to harness them. Even though a neighboring private solar farm had been wiped out (thus freeing up the protected hardware for inversion, regulation, and storage for purchase or rental until their solar panels could be replaced) the base command structure was paralyzed. Even though Tesla was generously donating these self-contained devices on the island- they couldn’t ask for or accept help. It was a cluster-fuck of red tape that effectively prevented a US Coast Guard base from acquiring power or communications.

A year ago, Javier Malave, now with Puerto Rico Science and Trust, created a partnership between Gotenna, Inc., the University of Puerto Rico (E-ship network) d/b/a PR_Reconnects and Starting Point, Inc. to raise approximately $20,000 (with Gotenna matching every dollar donated 1:1) to provide up to 300 satellite-backed Gotenna devices to provide emergency communications to the island’s “hundreds of thousands” hardest hit in the central mountainous regions and to help first-responders in the relief and rebuild efforts. The fundraiser was quickly fulfilled by 212 kind souls who donated funds. However, Javier Malave, PR_Reconnects, and Starting Point quickly went silent -unreachable even by partner Gotenna.

It’s now been a year, yet barely 16 (of the 300) permanent Gotenna relays have been established — all of them in San Juan, and conveniently extending out to Barranquitas, conveniently surrounding Javier’s home in the Palace of Versailles in Toa Alta and linking him and his family to the network in San Juan. While the goals of the fundraiser were to make these devices available to the public, none of the locations (other than the San Juan nodes) have been made public. It is therefore impossible for first-responders to leverage this critical national infrastructure. All attempts at bonafide requests for status updates from any of the partners have resulted in lies, bullshit aspirational “soon,” or attempts to change the goals of the fundraiser, them silencing whistle-blowers, deleting posts, suspending and then banning accounts for a thousand years. No accountability, no progress. Corruption.

First and crucial steps remain unfulfilled nearly a year later.

Puerto Rico is fundamentally broken — and like a child living in their parents’ basement, they will never mature to the point of self-sufficiency, sustainability, and independence while we continue to coddle them and support them with seemingly unlimited taxpayer funds. Anything given to them is not appreciated because it wasn’t earned with the sweat and labor of their own hands. While it’s noble to try to help, it does no good. Give them independence, let them build their own networks with the fruits of their own labor. Let them realize the failure of monopolistic PREPA, of corrupt contracts that prohibit common-sense harm mitigation. While this administration calls its response an “unsung success,” the reality is that it was an abject failure — an “embarrassment” as Admiral McRaven honestly assessed, even stopping its own military from taking steps to preserve life and maintain operational readiness. Perhaps we can earn Boricuas’ respect and friendship with the next administration and in the coming decades prove to be better brothers and sisters than a wayward parent buying forgiveness.

Political pressure has lead to the expedited and jooked stats claiming 99% of power and communications being “restored.” If nothing else, heed this warning- these power and communications lines were put up in a rushed manner and they are not robust. Even a light breeze or a minor tropical storm is going to result in Puerto Rico rapidly returning to the stone ages and thousands more casualties. Ropa viejas, a mangled mess of threads entwining everything, will be dipping into flooded streets and dangling from poles. Common-sense power backups providing self-sufficiency like the thousands of solar panels are hampered by an embarrassing administration which has hamstrung our military. Efforts to establish reliable backup communications are dashed by corruption and self-serving individuals without any effective checks or transparency; watchdogs afraid of blowing a whistle. The billions in disaster relief blown on putting up FEMA bureaucrats in fancy air conditioned waterfront hotels, villas, and mansions in Isla Verde with 3 square meals a day draining the hotel bars… while the people who were actually there to help, like Piratas Hurricane Relief, Black Flag Search and Rescue, Valor Response Team, Community Emergency Response Teams, and unaffiliated individual volunteers camped out in their cars and in tents in the thick of it — eating beans and lukewarm Medallas which were cheaper and more readily available than water.

Let capitalism, free market, and competition weed out corruption, weed out ineffective strategies, weed out liars, frauds, and disadvantageous monopolistic contracts. Step back and let them grow up. And FFS, can we get an administration that’s not an embarrassment- one that actually values leadership and empowers our military, one that doesn’t disenfranchise our Admirals and public servants?


An analysis of 2 primary concerns with allowing Twilio text 911 sms relay from Gotenna devices:

An analysis of 2 primary concerns with allowing Twilio text 911 sms relay from Gotenna devices:

(I) it may not work; and,

(II) it may result in abuse.

I. To address the first concern (efficacy):

It does work, below is a Gotenna Twilio SMS relay to Text 911 prearranged with Puerto Rico 911 PSAP center:

Note, Gotenna’s app does not allow for the entry of only 3 digit phone numbers and it requires a leading country code (1). The way we were able to make this work was to input the 1, then pad the phone number entry field with zeros. (e.g. 1–000–000–0911 == 911)

In life, there are things, that may not work… however, these things can give us a fighting chance. The ONLY guarantee is that they will NOT work, 100% guaranteed, if, like Gotenna and Twilio, we don’t even try or we shy away from the challenge by forbidding any attempt with restrictive acceptable use policies.

This is a difficult technology and, at present, the implementation of text 911 is far from perfect, except in Puerto Rico where it is 100% implemented for almost 8 years now.

Gotenna offers some unique features that increase the likelihood of text 911 sms relay working. Gotenna has 1–2 miles of range per hop (even 62 miles range with elevation). Often times a user may not, themselves, be within range of a working cell tower, but a couple of miles away, another Gotenna relay may well be within range of a tower or a wifi signal. Gotenna users generally set up a permanently powered relay near their house with access to wifi.

Gotenna offers up to six hops (i.e. 6 hops x 2 miles = 12 miles or 6 hops x 10 miles = 60 miles) if any of these users within an e.g. 12–60 mile range do have signal then the message could be sms relayed via that working tower to text 911. Often times a CDMA (e.g. Sprint/Verizon) tower may be down, but a GSM tower (e.g. ATT/Tmobile/Claro) may be operational (this allows Gotenna users to spread the load out to other towers they may not ordinarily have access to) and multiplies the likelihood of getting a message out.

While voice calls can easily overwhelm the towers and the 911 PSAPS, short text messages (tagged with GPS) reduce the need for such voice calls- easing the burden on the PSAP and the towers.

So Gotenna in concert with Twilio multiplies the likelihood of effective delivery of emergency messages by:

(1) being vendor agnostic, working on ANY available tower or wifi (i.e. CDMA/GSM/Wifi);

(2) by spreading the message out geographically by e.g. tens of miles beyond the disaster situs (very helpful for localized disturbances);

(3) by reducing the need for voice calls which frees up cell tower and PSAP resources;

(4) by including a GPS position — so even if the user can’t report or is lost, 911 services can locate the survivor.

Further, Gotenna performs an initialization at each and every use based on GPS location to intelligently configure the device based on the local jurisdiction and operational laws. The FCC makes the text 911 data available in one centralized and publicly accessible psap database. It would be trivial to programmatically configure the Gotenna to try 911 sms relay or not based on this GPS location or determined operability of text 911 in the jurisdiction.

Or, we just try… if it doesn’t work, at least we tried… and a 50/50 chance is better than a hard-coded 0% chance. As time goes on, more and more PSAPs will be text 911 ready. With sufficient click-wrap license, with conspicuous warnings, we can let the user know that this might not work — but at least give them a fighting chance.

There are many places that this will work. For example, Puerto Rico- millions of people in Puerto Rico, locals, servicemembers, and first responders… ALL 78 municipalities of Puerto Rico have 100% operational text 911 service and have had it for almost a decade. Large areas of California, Nevada, Connecticut, Texas, New Hampshire, Vermont, Indiana, all have operational text 911 service. 80% of Florida will have operable 911 text service by January 1. Thousands more locations have working text 911. Many disaster-prone areas could use this technology to save lives.

We cannot deny them that fighting chance just because it’s difficult and may not work. Could we try a pilot program JUST for Puerto Rico? We are open to ANY compromise. There are millions of American lives there and hundreds of Gotenna devices already there.

II. To address the second concern (abuse):

In stark contrast to Gotenna (as outlined below), any kid can buy a burner phone for $19 at walmart or a gas station with untraceable cash or find/steal/trade a phone anywhere.

The phone doesn’t even need a subscription to service to work for swatting. As you know, 911 calls and texts must be allowed even if there’s no sim card or preexisting service. Even if the device does have a sim card, many prepaid options exist and allow pseudonymous registration. So anyone, anywhere, with a few bucks, with 100% anonymity can already abusively call or text 911. This doesn’t even address the online services accessible with TOR or other means. Any argument that allowing Gotenna to sms relay to 911 must be forbidden because of potential abuse is specious considering the relative ease of employing a burner phone or online service.

However, with Gotenna, there are trivial steps that we (or gotenna or PSAPS) could use to mitigate this risk and several unique features that inherently limit the attractiveness of abuse on this platform:

1) GotennaPlus sms relay requires purchase of $130 worth of Gotenna devices with a credit card, a name, a mailing address, and a billing address and a $9 yearly subscription where the serial number is tied to the subscriber- why spend $139 when you can steal any phone or buy one for $19?

2) Registering GoTenna plus requires a working phone number (verified with Twilio and Gotenna);

3) Gotenna’s routing protocol maintains GPS location of the originating node (AND every relay node- establishing a breadcrumb trail with up to six GPS locations) this allows for simple verification, fuzzy logic forensic location/fraud detection. This can be easily provided to the PSAP center or LEO’s in some simplified form and maintained to go after abusers or to proactively prevent abuse. In this sense, it makes Gotenna much less attractive for abuse.

4) Gotenna locations can be triangulated (in addition to the GPS trail).

5) Gotenna terms explicitly state that they can revoke access if there is abuse.

So, even though there is (1) a *significantly reduced* likelihood of abuse relative to other services, and (2) even though it guaranteed WILL work in several disaster areas like Puerto Rico, we guarantee that NO ONE can call for help because someone, somewhere, may abuse it or it might not work?

Either of these propositions by Gotenna / Twilio:

(1) We cannot try to help people because it might not work; or,

(2) We cannot try to help people because someone (however unlikely) might abuse it…

violate both the zeroth and first law (…allowing humanity to come to harm through inaction).

Bad storms, hurricanes, earthquakes, tornadoes, tsunamis are coming with increasing frequency and ferocity — to do nothing is to go silently into the night.

This Gotenna device is the only device that works for people like my mother when the tower falls- it increases the likelihood of her survival exponentially. This device is what we outfitted five teams of first responders with in Puerto Rico for search and rescue and convoy missions. It works. Twilio’s SMS relay will save lives and help us save more lives.

I was over there in Mountain View, Los Altos in ’89 when the earthquake came and we lost everything. Imagine the survival advantage you give us for next time if we can use ANY remaining cell tower or wifi (not just Sprint or ATT). Meta-signal diversity. This is huge.

I’m humbly and respectfully begging, could we please have a variance, a waiver of the Twilio Acceptable Use Policy to try a pilot program sandboxed JUST for Puerto Rico or just bay area? We are open to ANY compromise. There are millions of American lives there and hundreds of Gotenna devices already there.

Let’s be heroes. Let’s lead by example. Let’s tear down walls. Let’s make the effort to do this, not because it’s easy, but because it’s hard and we don’t shy away from a challenge or saving lives when it’s possible.


When Twilio’s “acceptable use policy” Trumps Human Life


A woman at Burning Man out in the middle of the Black Rock Desert was seriously injured with third degree burns and was unable to call for help by any other means.  There being almost no cell service, and her location at the far periphery into the desert, a good Samaritan called for help using the Gotenna Mesh network which allows text and gps messages even when there are no cell towers.

A really killer feature of Gotenna Mesh is that a message like this can be sent and it will hop from Gotenna device to Gotenna device in mesh fashion or p2p up to six times. The distance of each hop depends on a number of factors, but is generally about a mile or two (or up to 62 miles with elevation).  For example, the woman who was calling for help was at 10:00 and Esplanade or E (the user was confused as to location) fortunately, Gotenna includes an actual GPS location as metadata within the message.

where was she

While she may have been out of range for some of the Gotenna Device meshes, I had placed a permanent relay Gotenna device node on the highest mountain overlooking the playa with full solar power to keep it going all week.  So when the message went out, I received it – as did others because of this relay.

However, no one knew where she was. The address she had given (10:00 and Esplanade) was wrong.  Signs had been stolen, jokes had been played on signs all week, and many of the signs were changed to “Larry” or “L” or “Larry4Ever” to show respect and love to the founder who had passed.  So her position was unclear.  Each Gotenna message stores the GPS location of the original sender, and the GPS location of each relay point, as metadata (not visible to other users) but with a breadcrumb trail of all six relays, the resolvable ultimate position would be invaluable to first responders.

There is another killer feature of Gotenna that makes it essential in all first responder’s or those who live in danger’s go-bags. GotennaPlus SMS relay. It’s $9 a year or FREE for up to 30 days each time you install the Gotenna app.  What it does is – if your intended recipient isn’t available by Gotenna, but any one of the six intermediate relays has cellular data or wifi or satellite or ANY kind of signal, the message is backhauled or forwarded out to the internet and then through Gotenna or Twilio’s servers, to the recipient as a text message.  Gotenna and Twilio presumably maintain records of the message AND THE METADATA including at least one GPS location.

Before the event, I had contacted Burning Man Emergency Services, Washoe County Sheriff, and Pershing County Sheriff along with their 911 PSAP centers to confirm that they do, indeed have TEXT 911 operational and to give them a heads-up about this device and the perhaps odd 911 texts they may receive.  They confirmed that there is, indeed, operational text 911 service. What this means is that if you have an emergency and you cannot use voice to dial 911… maybe because the tower is too far, or too saturated with other voice calls, or you are hearing impaired… or any of a million reasons why you may not be able to use traditional voice 911, Washoe County (host of Burning Man) is 100% set up to receive emergency messages via text! The same text 911 capability is 100% operational in all 78 municipalities of Puerto Rico, and thousands of other locations.  For example, Gotenna did a fundraiser to install up to 300 of these Gotenna mesh units to create a backbone in Puerto Rico. Over a hundred thousand of these tiny celltowers in your pocket are distributed all across the world.


So, the good Samaritan had employed his Gotenna registered and verified to his cell phone number via both Gotenna and Twilio services. He had sent out not just any message, but an “Emergency” message along with the GPS location of the emergency as metadata.  Because none of the Law Enforcement or Burning man people accepted the Gotenna devices I offered them, it was up to volunteers to find a ranger, explain the situation, and deliver it manually, verbally to dispatch help promptly to the user-reported location. (Mind you, volunteers don’t have access to the GPS metada) however, if the message had used Gotenna Plus SMS relay to send the message to text 911, they may have immediately known where she was, had the registered number of the good Samaritan, known the locations of the breadcrumb devices that relayed and the girl could have been saved promptly.  Sometimes it’s mere minutes that can mean life or death.

In this case, we didn’t know where she was, we didn’t know her gps location, we didn’t know the locations of the relays, we couldn’t triangulate, we didn’t have cell signal – so we couldn’t call the good Samaritan. I approached the rangers, asked if anyone else had reported this burn situation. They said no, called central comms for confirmation. No reports. No burnt girl in medical.  They went to find her at the best approximate location I could give (which was wrong). I went to the airport to try to reach the good Samaritan by phone number as there is indeed limited cellular service at center camp and at the airport.  Failing this, I went to the reported location and looked for her.  But, to my knowledge, no one ever found her… and she eventually gave up and walked into the desert to find help.


As it turns out, these messages could have IMMEDIATELY been forwarded to text 911 along with GPS location – and someone’s daughter might still be with us… BUT FOR Twilio’s Acceptable Use Policy which squarely forbids relaying ANY message which is an emergency.  So, they are happy to accept your subscription to relay messages about your cats, but the moment you actually need help… FUCK YOU! Even if there is NO OTHER WAY to reach 911, Twilio: “FUCK YOU.” Even if it could save a young girl’s life.. Twilio: “FUCK YOU.” Even if it could save hundreds of thousands of Boricua in Puerto Rico… Twilio: “FUCK YOU” send your cat pictures, but leave us alone in an emergency.


I have made them aware of this by Twitter, Facebook, Instagram, Email (MONTHS AGO), even by sitting vigil at their headquarters with a projector and a ten foot banner. Some of their geeks and support staff came and talked to me and understand the problem. I reached out to every member of their board and their management team. But still do not have any response other than “it violates our acceptable use policy.”

Real lives are on the line here. This isn’t an isolated incident. Hundreds of thousands of these Gotenna devices with Twilio SMS relay are out there in the hands of stupid drunk/drugged kids, in 107F heat, wandering areas of the desert they probably shouldn’t be alone in shock in.  These devices are in the hands of Puerto Ricans and Bermudians and Annapolitans all in the path of severe hurricanes – and when the towers fall again, Gotenna Mesh is (at present) the ONLY device that will enable communications and location sharing.

Twilio needs to find a compromise that allows these survivors to waive warranties (clickwrap license?) and at least TRY to forward their emergency messages to 911 services where they exist.  Gotenna intelligently and selectively sets frequency and power based on GPS location at each use; they should include a subroutine that determines text 911 operability as well.  Gotenna should have a conspicuous disclaimer that although they offer “Emergency” and “SOS” messaging and SMS text relay – that even in areas with operational text 911, that this feature will not work – OR SIMPLY MAKE IT WORK! Cut the red tape, cut the over-regulation, ignore Twilio’s “acceptable use policy” or find another sms/text relay service like e.g. Broadband which ALLOWS 911 emergency relay.  Whatever the solution, it is clearly NOT the status quo…

Twilio may be able to close the blinds and ignore me outside, may be able to block me on social medai… but the mother and father of this girl can’t just close the blinds on their pain.  Closing the blinds won’t help the hundreds of thousands of souls that Twilio and Gotenna could save when the next storms hit.




Is Gotenna Mesh (GotennaMesh) Right For Your Team Responding to Hurricane Lane?


If you are heading to Hawaii for #HurricaneLane, and your volunteers are not ham radio licensed, and your budget does not allow for a $500 Garmin inReach Explorer Plus satellite communicator or $250 for a Spot X satellite messenger (either with $14 a month month-to-month service – no contract required), then you definitely should look into Gotenna Mesh devices, especially if your team will be confined to several miles of each other.  These work particularly well in Seach and Rescue (SAR), convoys, and around base-camp.

Gotenna works about .6 miles (per hop with up to SIX HOPS allowed) under normal non-ideal conditions (i.e. poor placement altitude, obstructions, no relays, high noise floor, and beginner, untrained users…).  If users orient the device in a vertical orientation, place them on the top of their backpack, strategically place a relay device somewhere high, then users are more likely to get several miles of range.  For advanced users, raising a centrally placed relay device atop an antenna, light pole, tree, mountain, or on a drone, up to 62 miles of range may be possible. If operations are constrained to one area, strategic placement of a right-angle reflector or cantenna can double range with some users seeing 5 miles, others (at altitude seeing 29 miles).  For expert users, light surgery to upgrade the internal antenna to an SMA connector shows great gains when coupled with external antennas.

Even more importantly, if ANY user within Gotenna range (within 6 hops) does have cell service or wifi service, then EVERY Gotenna user within range is able to relay one-way text / simple message service (SMS) messages to anyone in the world (even if they don’t have a Gotenna device).  Moreover, if your team has IT support geeks, Mesh Developer Toolkit (only available on iOS) allows for backhaul across the internet, twitter, or custom web-servers.

These features provide a significant advantage for first responders, survivors, and others operating in disaster areas which may not have cell service.  This is a force multiplier. If, for example, a volunteer has Sprint service and a gotenna, but Sprint service is down… but several other team members have GSM phones, like ATT, Tmobile or CDMA Verizon, Sat phone, or someone is near a public wifi that’s working, then EVERYONE in the team can use whichever network is working at the moment – automatically without any user intervention or customization.  *IT IS IMPORTANT TO NOTE THAT THIS IS NOT BIDIRECTIONAL, but being able to get a message out sometimes can be the difference between life and death.*

At only about $70 per Gotenna device, this may prove much cheaper and more immediate than buying ham radios, classes, and licensure for each operator.  Additionally, Gotenna only draws between 100-400milliamps to charge at about 4.74Volts (.4 – 2Watts power draw) meaning that they can charge and stay charged for several days from any source – even a tiny solar keychain device.  Whereas even a BaoFeng ($30 but requires a license) requires at least 12V at 400milliamps (about 5Watts) to charge (with losses in the multiple voltage conversion steps).  Moreover, ham radios require training to use them correctly and avoid misuse or interference with LEO and emergency calls. Whereas Gotenna devices, in contrast, are easily employable with the user’s own phone where they are very comfortable.  Gotennas are very simple devices to use – evinced by the fact that a month after launching the latest software, there’s still no user manual – without public outcry. They simply work.

Before sending your volunteers into harms way, admins should consider outfitting teammembers with Gotenna devices, Sonim XP8 hardened phones, and Next Radio app (with headphones to serve as an antenna) to allow for offline radio alerts even when cell and wifi networks are down.
