Sonnet device turns a smartphone into a walkie-talkie that works without a cellular network

Our smartphones do not work when they are out of network coverage, the network is congested or unavailable (for example, during natural disasters). Unlike them, walkie-talkies work always and everywhere, but they have a number of drawbacks - they are large, heavy, and transmit sound of rather low quality. The new Sonnet gadget gives ordinary smartphones all the benefits of an always-on wireless connection found in walkie-talkies.

Sonnet creates its own mobile network that allows smartphones to work even outside the coverage area of ​​providers and without access to the Internet. It can be used to send instant messages, voice recordings, pictures, files, GPS coordinates, and more. Its capabilities will come in handy not only on a long hike away from civilization, but also when traveling abroad or at major events, during which cellular communications are usually completely paralyzed.

Sonnet uses low-power, long-range radio frequencies, making it independent of cellular networks and providers. The gadget connects wirelessly to a smartphone, which can then transmit data up to five kilometers away to other smartphones associated with Sonnet. This distance increases to 15 kilometers if there are no large obstacles between the modules.

Sonnet uses mesh networking technology, which allows it to transmit data through other users in the vicinity. This expands the coverage area of ​​the gadget to a theoretical limit of 80 kilometers.

Other useful functions of Sonnet include: a set of offline geographic maps in the gadget app, an emergency beacon, and a 4000 mAh battery that allows you to charge its owner's smartphone.

The gadget weighs only 160 grams, has IP66 protection, and will be available this November for $ 90 per pair.
