Communicate without cell, wifi & satellites using your existing smartphone. Relay messages through other users to extend range!
goTenna Mesh is the first 100% off-grid, mobile, long-range consumer-ready mesh network. The device pairs with your smartphone to enable communication even when you don’t have service. Absolutely no towers, routers and satellites required! Create people-powered connectivity absolutely anytime, anywhere.
Send text messages and share GPS locations on offline maps with others. Chat privately in 1-to-1 or group conversations, or broadcast to any other goTenna Mesh device up to several miles or kilometers away all without using towers, routers or satellites.
Each tiny-but-mighty device is powered by game-changing networking protocols which intelligently — and privately! — relay messages through other users. You can potentially double or triple any device’s effective range and create a network that gets stronger the more people join it!
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!)
Super-smart protocols enhance functionality & make it easy for you to use
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!
The freedom to communicate over great distances, no service required
goTenna Mesh sends messages via a 1-watt UHF radio transmitter without relying on towers, routers or satellites. The range will usually be up to 3 miles (4.8 km) in open terrain, and up to a mile (1.6 km) in congested terrain. You can get much more in certain environments but we like to under-promise and over-deliver. (Plus… you can mesh!)
(goTenna Mesh uses publicly available spectrum, intelligently selecting frequencies that are available in your region.)
Revolutionary mesh networking technology (the future is now!)
goTenna Mesh’s first-of-its-kind mobile ad hoc networking (MANET) protocol enables you to intelligently relay your messages through other users to get to your recipient(s) when they are out of point-to-point range of you. This makes it more likely your messages will get through in difficult situations, and creates a network that gets stronger the more people join it. And not to worry: this all happens automatically and privately.
Here’s a demo that helps explain how meshing works, using prototypes & phones in Airplane Mode. Because transmissions between goTenna Mesh devices are literally invisible, we’ve added voice-over to explain what’s happening:
When to use goTenna
Keep in touch with those you spend time outdoors with, from hiking to skiing to fishing, and just about anything in between.
No more expensive roaming fees or international SIM cards — simply use goTenna to stay connected with your travel-mates on trips abroad.
Enjoy the crowd without getting lost in it — avoid overwhelmed cell towers at packed festivals and crowded events and stay in touch with your group.
Exchange critical communications with friends and family as well as others nearby during emergencies, even when the power is out and cell towers are down.
