BBC - 15.09.07
A new way of making calls directly between phones, for free, is being trialled by a Swedish company. It is hoping to dramatically improve communications in the developing world.
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. This collaborative routing of calls means there is no cost to talk between handsets.
When a TerraNet phone is switched on, it begins to look for other phones within range. If it finds them, it starts to connect and extend the radio network.
