Mobile system promises free calls

TerraNet hope their network will become a standard featureA 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.
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.
Projects backed by TerraNet recently launched in Tanzania and Ecuador.
TerraNet founder Anders Carlius told the BBC World Service's Digital Planet programme that the idea for TerraNet came when he was on safari in Tanzania in 2002, and found that poor connectivity meant he could not ring friends riding in another jeep only a few metres away.
"I started thinking, 'couldn't we get phone-to-phone without needing any other equipment, and actually have real voice communication, like a telephone call, between units?'" he said.
