Any mobile phone, from a conventional push-button device to a smartphone, functions only when there is a signal from a cellular operator - the mobile network.
Despite the rapid technical and scientific progress in the field of gadgets, during natural or man-caused disasters the network is lost due to heavy workload. The same happens when mass events are being held. In the countryside, on hikes or any remote places, cell phones can be in the zone where there is no coverage of providers providing communication services.
In contrast to cell phones, walkie-talkies work always and everywhere, but they have a number of drawbacks - they are large, heavy, and transmit a sound of low quality. If you are in an area where there is no coverage or satellite communication, useful and already familiar devices like a smartphone and a GPS-navigator will be completely useless, although it is in this situation that communication can be vital. The Toronto-based Sonnet Labs offers a new solution for this problem with their Sonnet connection device.
The new Sonnet gadget gives ordinary smartphones all the advantages of a constant wireless connection, typical for walkie-talkies.
Sonnet is a device that is smaller than a portable base station, and it represents a base station to some extent. So to say, your personal BS of your personal mobile operator. And it’s all completely free.
Sonnet creates its own mobile network, which allows smartphones (Android, iOS) to work even outside the coverage area of providers and without access to the Internet. To start communicating, you need to install a special Sonnet application on your smartphone, set up the transmitter yourself and connect to it via a wireless Wi-Fi network. With the Sonnet gadget, you can send instant messages, voice recordings, pictures, files, GPS coordinates and much more. Its capabilities will be useful not only during long offroad adventures away from civilization, but also when traveling abroad or at major events, during which cellular communication is usually completely paralyzed.
Sonnet uses low-power and long-range radio frequencies, which allows it not to depend on cellular networks and providers. The gadget connects wirelessly to a smartphone, which can then transfer data to a standard range of 5 kilometers to other smartphones connected to a Sonnet device. This distance may be increased to a theoretical limit of up to 80 km (50 miles), if there are no major obstacles between the modules, for example, when the sender and receiver are located on top of two mountains.
The gadget works on the technologies and architecture of mesh networks. This means that the data can be relayed (transmitted) through all the similar devices that are within the access range. All transmitted content is securely protected by a secure encryption protocol. Cable connection is also available. The recipient of the data must also be a Sonnet user.
Other useful features of the Sonnet device include a set of geographical offline maps in the Sonnet app, an emergency beacon and a capacious 4000 mAh battery that allows you to charge your smartphone, IP66 degree of protection (dustproof, resistant to strong liquid jets); set of cards.
The Sonnet device is a compact but advanced gadget. Unlike walkie-talkies which are large, heavy devices with low signal quality, Sonnet has a "modest" size of 88x80x17mm and a weight of 160g.
Sonnet Labs have already gained financial support for their project on Kickstarter. The gadget will be available in November this year at a price of $ 90 per pair. Don’t miss the sale of this incredibly useful gadget.
