It generates its own signal, which means exactly zero cell towers, wifi or satellites are required! In fact, goTenna will even work if your phone is in "Airplane Mode"!
Use goTenna when you're off-grid — outdoor activities, crowded events, travel, emergencies — or when you want to be, because it's end-to-end encrypted.
1. Pair with iOS or Android
Your smartphone and goTenna wirelessly connect over Bluetooth-LE, as long as they're within ~30 feet of each other.
2. Use the easy goTenna app
Type out texts or share a location, just as you would in any familiar app. Chat 1:1, with a group, or even broadcast to all users within range.
3. Generate an off-grid signal
When you hit "send," goTenna shoots out long-range VHF radio waves (151-154 MHz) to your intended recipient(s). Your message is delivered in-app at the other end.
4. Create your own network(s)
goTenna is smart and automatically coordinates with other units within range. It does all the heavy-lifting so you can communicate on your own terms, no matter what.
The most important thing to understand about goTenna's range is it's greatly dependent on your terrain and elevation. While the theoretical max is 50 miles, that's only mountaintop-to-mountaintop. The higher you go, and the more open the geography you're in, the greater your range. Below are the likely ranges in common scenarios:
City street to city street
Forest to forest
Water to water
Desert to desert
