The goTenna enables you to communicate without any need for telecommunication Masts, cell towers, no wifi, no satellites—so when you're off-grid you can remain connected. In fact, goTenna will even work if your smart phone is in “Airplane Mode”!
How does it work?
Your smart phone will have to be paired with the goTenna device via Bluetooth-LE. When a message is sent the device shoots out the information via long-range radio waves (151-154 MHz) to the intended goTenna(s).
At the other end, the exact same thing happens, but in reverse: the recipient goTenna sends the message over Bluetooth-LE to the receiver’s smart phone app it's paired with. All of this happens in a matter of milliseconds.
