With no service required, goTenna Mesh allows you to, with assistance from the goTenna app, to “pair to your phone and create your own signal when off the grid.” With goTenna you can send texts (1:1 or group), GPS locations or public broadcasts to all users in your area. Mesh occurs when an another goTenna user is in your area and “your phone hops to theirs and extends your network even further. You can strategically place goTenna devices in your area to extend your own coverage.”
Transmitted on UHF frequency, goTenna signal extends farther than a walkie-talkie- by more than 40% more range.
