No Network? No Problem. Texting without Cell Service.

When there's no cell service available, how do you communicate with family and friends? In the midst of a disaster, how do you get updates? We're used to the "always on" world, but in times of disaster and crisis, your primary source of communication is often not available - texting. Hello GoTenna. GoTenna uses an app on a smartphone coupled with a portable, battery powered short-wave radio transmitter/receiver, to send and receive text messages from other devices up to 50 miles away - without cell service available. Daniela, a startup guru, and Jorge Perdomo, a system architect, filled in the missing link: a device that would allow communication to continue when there’s no cellular or Wi-Fi service available. goTenna devices turns smartphones into standalone bidirectional communicators. Callers link the small dongles to their phones over Bluetooth and launch the goTenna app. Users compose a text message, which then relays through the goTenna. The signal passes over a short-wave radio frequency to the recipient’s device, which in turn displays the message through the app. If the recipient isn’t within range, the system will automatically resend the message until it goes through. Individuals can opt to send messages to one recipient, blast them to an entire group or ping alerts (what the company calls “shouts”) to other goTenna users who are within range. Messages can also include a user’s precise location on a map. Company Website GoTenna Additional Articles Smithsonian cNet The Register...
