BBC News| Technology Swedish company TerraNet has developed the idea using peer-to-peer technology that enables users to speak on its handsets without the need for a mobile phone base station. The technology is designed for remote areas of the countryside or desert where base stations are unfeasible. … The TerraNet technology works using handsets adapted to work as peers that can route data or calls for other phones in the network. The handsets also serve as nodes between other handsets, extending the reach of the entire system. Each handset has an effective range of about one kilometre.
