Using GoTenna Mesh
GoTenna Mesh works absolutely anywhere on earth, provided there is at least one other GoTenna Mesh device in range. Whether you are traveling overseas, spending time outdoors, at a crowded event, or preparing for an emergency, GoTenna Mesh provides incredible utility in any situation where cell service or wifi is not available by empowering you to create essential connectivity during any adventure.

You can chat with any other GoTenna Mesh user within range. The reason you can't chat with people who don't have GoTenna Mesh is due to the physics of radio waves. You need a properly designed RF receiver to interpret a GoTenna Mesh signal. It will not send signals to devices that aren't GoTenna-enabled, since phones are designed to work with towers and wifi — exactly what GoTenna is working around — and regular radios aren't able to operate at the level of super-smart networking protocols offered by GoTenna. Also, GoTenna Mesh devices does not be interoperable with regular GoTenna devices because they operate on different frequencies. With that said, the GoTenna Plus app upgrade enables an SMS network relay feature, so you can reach people beyond your off-grid network. If a GoTenna Mesh user nearby has cell service, they can transmit your message via SMS to your intended recipient.

Range & Performance
A powered goTenna Mesh device can receive and relay messages and location data. goTenna Mesh does NOT need to be actively paired to a smartphone to serve as a relay node, but it does have to be powered on. This enables users to use goTenna Mesh devices as stationary relay points in strategic locations to increase range. As an example, image two users have four goTenna Mesh devices. Two of those devices can be used solely as relay nodes, increasing potential reach of the mesh network: User A — User B, User A — Relay Unit 1 — Relay Unit 2 — User B.
Because goTenna Mesh has a standard micro-USB port, you can leave the device paired to a power source if you plan to use it as a relay node for an extended period of time. Point-to-point range depends on your environment, and no situation is exactly the same. That being said, more open terrain often allows for greater range; line-of-sight can also help but is not required. Plus: you may be able to extend your range through other goTenna Mesh devices by relaying.
For best performance, you should try to attach goTenna Mesh externally to gear and elevate it as much as possible. For instance, attaching goTenna Mesh externally to your backpack is better than placing it anywhere inside your backpack. Also note that goTenna Mesh is not designed to be used when directly in contact with your body. The reason being that the human body can interfere with radio transmissions, including goTenna Mesh’s signal. Holding goTenna Mesh in your hand or putting in the chest pocket of a thin item of clothing could noticeably decrease your range. That said, if you want to hold it up for more height, hold it from the strap, avoiding touching the metal and plastic casing. If you put it in your pocket, try to pick a thick clothing material so the device doesn’t make contact with your skin.

In general, you can expect up to 4 mi (6.4 km) point-to-point range in open environments such as plains, desert, beach-side, etc. Expect up to 0.5 mi (0.8 km) point-to-point range in congested areas such as cities, mountains, ravines, thick forests, etc. Don’t be surprised if you get a lot less or a lot more than this — it’s quite common to get only a few blocks in very dense urban areas and the current ground-to-peak point-to-point range record for goTenna Mesh is 10 miles. (A skydiver set the open-air range point-to-point record: 26 miles!)

Private 1-to-1 and group messages sent over goTenna Mesh are end-to-end encrypted with 384-bit elliptic curve public-private key ciphering. The only exceptions are messages sent using the “shout” and “emergency” features which are by definition public conversations with others within range of you. GoTenna is very secured. Beyond the end-to-end encryption, because there is no central server there is no proverbial back-door. GoTenna mesh device does not share your usage information with GoTenna company, though you can opt-in to share completely anonymized telemetry when you have a data connection, so that GoTenna can improve their service. Again, this is limited to basic data regarding battery life, device temperature, and so forth. No messages or contact list info are included.

3) GoTenna PRO
GoTenna Pro is one of the smallest, lightest, most affordable tactical mesh networking radio in the market and it works with any smartphone.
GoTenna Pro helps teams achieve full situational awareness by combining long-range burst data transmitted over VHF/UHF with smartphones’ simple user interface (iOS & Android). Created with enterprise, public safety & defense users in mind, GoTenna Pro powers reliable and resilient communications via a high-performance ruggedized radio and advanced ad-hoc mesh-networking protocols. With single-hop range often measured in miles, GoTenna Pro further redefines off-grid communications via multi-hop mesh networking protocols. Self-healing, self-defined, and with no setup required, GoTenna Aspen Grove Pro mobile ad-hoc networking (MANET) protocol ensures reliable and resilient communications in even the toughest environments. Every GoTenna Pro unit functions as a cognitive multi-hop mesh node for all other Pro units — even if unpaired to a smartphone — and all relayed data is done so privately and automatically. Meshing eliminates or reduces the need for base stations and repeaters, as every GoTenna Pro provides that same functionality. GoTenna Pro’s functional capabilities come together to provide the two most important parts of mission-critical operations: situational awareness (SA) and tactical command & control (C2).

GoTenna Pro Specifications:
It is 12x lighter and 10x smaller than legacy comms systems.
Size: 5.3 x 1 x 0.7 in or 134.62 x 25.4 x 17.78 mm
