goTenna Mesh is the device for off-grid communication using unique network technology. It’s sold in pairs. Each device connects to a smartphone using Bluetooth. As long as they are within the effective range of the devices, you can communicate with each other using their own radio signal without cellular service or internet. A type of communication is very limited, though. You can only send and receive text messages and share your locations on an offline map using a smartphone’s GPS. What the unique network technology goTenna Mesh uses is the range of the device can increase significantly when more devices are in the vicinity.

What is the range of goTenna network?

It is difficult to assess or predict the range of goTenna network. It depends on many different factors such as the terrains, the number of devices your group uses, and most importantly, the number of devices outside of your group use in a given area.

Let’s think of the simplest situation to understand how goTenna works. Say you and your friend use a pair of goTenna devices, and they are connected to your smartphones. You guys can send messages to each other and also share your locations in the app when you two are within the range of the devices. The range of the devices depends on types of terrain, existence of buildings or electric interference. According to the manufacturer, the signal can travel up to 4 miles point-to-point range in an open area. In the area like a forest, mountain, ravine, or city, the signal is still expected to travel up to 0.5 miles.

Now, you guys start walking in different directions. When you are far away from each other, you think you got outside of the range, you try sending a message. The message is delivered, and you got a response. You share your locations, and then you know you guys are now 10 miles away from each other. Why can you still communicate?

Imagine someone who has goTenna appears between you and your friend, and someone’s device is within the range of both you and your friend’s devices. Although your two devices are far outside of the range, you can still communicate with each other by using someone’s device as a relay. The “someone” doesn’t need to be your acquaintance. Your messages just hop on his or her device. He or she doesn’t even know that you are using his or her device as a relay to send your message to your friend. He or she may be using your device as a relay to communicate with his or her friend.
