It shows a device that allows to use a smartphone in the absence of any communication networks
What if you suddenly need to make an important call, but the phone connection was lost? The modern city is easily fixable, but what to do if you are in a remote village? Or even in the mountains? Of course, in such cases, there are satellite phones, but they are still bulky and expensive to use. Fortunately, there is a solution. Not so long ago Sonnet Labs from Toronto presented a set of devices, making it possible to use the cellular network, even if such is not observed nearby.
The new device is a digital radio operating in a distant radio ranges. At the same time to connect to the radio station smartphone even do not need a Wi-Fi (although this is available), it is sufficient to connect the phone cable to the station, and your smartphone will regain the possibility to make calls and send text messages, pictures, videos and even GPS coordinates . On the "other end" is another mobile phone that is connected to another base station. In this case, for the safety of the information should not worry - the data is encrypted using the AES algorithm.
Sonnet system can be activated automatically when there is no signal from the network. In addition, Sonnet can be used as a backup connection point in the field of natural disasters and other emergencies. The device can operate in the repeater mode, transferring data up the chain from one database to another, until they get a phone with access to the network.
Range one transmitter is about 5 kilometers to the open area 10 kilometers on a hill and about 2 kilometers in urban environments. battery built-in lasts for 24 hours of continuous use device.
