If you need a way of staying connected even when you can’t get a signal on your mobile phone, you may be interested in a new pocket-sized device called goTenna Mesh which allows you to communicate without cell, wireless or satellite connections, using your existing smartphone.
The system works by allowing you to relay messages through other users to extend your range. Check out the video below to learn more about this unique way of communicating even when there isn’t a signal available.
Whether you’re traveling overseas, spending time outdoors, attending a crowded event, or preparing for an emergency, goTenna Mesh is useful in any situation where cell service or wifi is unavailable, unreliable or unaffordable by empowering you to create essential connectivity during any adventure.
goTenna Mesh pairs seamlessly to smartphones via Bluetooth-LE (Low Energy, 4.2), with minimal smartphone battery usage. (In fact, you can even turn your phone into Airplane Mode to preserve its battery, as goTenna Mesh will still work. Just remember to toggle Bluetooth on!)
goTenna Mesh’s protocols do all the hard work behind the scenes so you can use the messaging app the way you’d use any other. Except, of course, goTenna Mesh will work when others won’t!
Using the goTenna app, send private 1-to-1 and group chats as well as broadcast to anyone within range. Count on delivery confirmation receipts, and easily download free, detailed offline maps of the entire world before you go off-grid. You’ll never have to worry about interference or channel-switching, the way you do with analog walkie-talkies. Radio + smartphone = intelligence!
