Weather Channel, with the support of IBM, has released a new Android application that is capable of transmitting messages between smartphones without cellular communication: warnings and instructions sent through it will reach the addressee during earthquakes, mass festivities, terrorist attacks and any other unforeseen circumstances, the blog says. Company.
A miniature by modern standards program - just 3.2 MB - was created specifically for the growing markets of Asia, Latin America and Africa. To transmit alerts, it uses Bluetooth and Wi-Fi networks and, according to the developers, is able to do this at a distance of 200 to 500 feet (60-150 meters). However, it consumes no more battery power than any other application and does not require changes to the network settings of the phone.
The application sends information directly from one device to another using Mesh Network Alerts, an IBM-developed data transfer technology. The principle of the technology is built on the interaction of cells, where each connected device acts as a switch for other devices. A large number of link-routes ensures that when the cell "drops out" the warning will still be delivered by any other possible path.
