SHTF: Send Text Messages Even After the Grid Crashes

From Natural News


If and when the power grid goes down — along with the cell towers that depend on it — we will all undoubtedly be asking ourselves the same question: “How the heck will I be able to order a pizza?”

All kidding aside, there is a nifty device now available which will allow you to send a text message over your smartphone — even when there are no working cell towers available.

This new gadget — called “goTenna” — could prove to be extremely useful in a number of scenarios, including disasters and quite a few other not-so-extreme situations, also.

So, what is goTenna and how does it work?

The goTenna website describes their product as a device which “pairs wirelessly with your smartphone, enabling you to text and share your location with anyone who has the device even if you don’t have service. No towers, routers or satellites required!”

It’s a relatively simple application of existing Bluetooth-LE technology. It requires a goTenna device at both the user’s and recipient’s end, and even though it has a limited range, it should prove to be an essential component of anyone’s bug-out bag and a potentially handy companion for those who spend any amount of time in the wilderness.

The device works as both a transmitter and an antenna/receiver. You can think of it as a digital age walkie-talkie since — like a traditional walkie-talkie — it has a limited range and requires the user at both ends to have the same device. It also requires the use of a smartphone app which is included when you purchase the device.

goTenna sends the entered text message from your phone to the device via Bluetooth and then transmits it to the goTenna at the other end, which also uses Bluetooth to send the received message to the recipient’s cellphone.

It works using long-range radio waves in the 151-154 MHz range to transmit the signal.

The transmission only takes a few milliseconds and it costs nothing to send a message, since it doesn’t require any central third-party connectivity.

The makers of the device say they were inspired to develop it in the aftermath of Hurricane Sandy, and that’s just the type of scenario where the device could prove to be extremely useful.

But it’s also potentially useful in areas where cell towers are out of range or where service is inconsistent. goTenna could also prove to be valuable for hikers or campers, in the case of an emergency or in the event of becoming lost.

One of the device’s cool and useful features is its ability to send a “shout” broadcast to anyone in range who also has the device — it can be used for individual and group messaging as well. This could prove to be a lifesaver in certain situations.

The only real drawback is the device’s limited range. Although its makers claim that in optimal conditions goTenna has a range of up to 50 miles, in most situations the range would be more like 5 miles.

Even though goTenna doesn’t rely on line-of-sight transmission, the signal is hampered by buildings and other obstacles. Its makers freely admit that the device’s range will vary in different circumstances, and the website does feature an interactive graph that allows you to estimate its actual range in a variety of situations.

Limitations aside, goTenna is a very clever and useful product that will almost certainly prove to be a success in the marketplace. It’s currently priced at around $150 for two units, making it a reasonably inexpensive investment, especially considering its potential usefulness in a number of situations


Useful for those that want to or need to get in touch with someone to let them know you’re okay. Probably wouldn’t be useful if the grid is down due to an EMP attack though. Your cell phone just might be fried!

    This might come in handy for close range, and if the entire grid isn’t down.

    It sounds like it has potential, but as happens with many electronics, if we wait a while, they will make improvements and the price will come down.

    Microwave ovens are a prime example – my first one cost $700 and weighed a ton, now you can buy one for under $100 and carry it home.

      I remember! I bought one last week for $40. I don’t have family at home, so why do need a huge one?!!

      That’s true!

      My first microwave was one of those first ones! My Mom and Dad still have one of those! It must be at least thirty years old now! They use it for warming up leftovers, so it’s been used pretty consistently. They don’t make them to last anymore like that!

    Another device the NSA can track your ass on. Good post, but no thanks.

      LOL! They have so many ways now it’s not even funny anymore! Yep…it probably has a tracking device…most electronics do now!
