We only realize how important something is when we lose it, the saying goes. This is also true for the network. Two New York creators fell victim to Hurricane Sandy in October 2012. Internet and phone connections were cut off. Thus, the absolute need for communication created Go Tenna.
The Go Tenna is sold in pairs and allows you to communicate even when there is no phone connection or wifi. It uses low frequencies (between 151 and 154 Mhz) and can cover a distance of 80 kilometers. This walkie-talkie of the future connects via Bluetooth to a smartphone application and is available for Android and IOS.
It is much more efficient than the walkie-talkies of our childhood and can send SMS to other Go Tenna users, at a distance of 80 km. It has been invented to serve situations where there is no network, such as when mountaineering, in the countryside or even in densely populated areas, where we see hands raised desperately searching for a frequency.
The Go Tenna pair will be available from October 2014 and will cost $149 (110 euros).
