A Swedish company is investigating an easy way to make calls between phones for free using P2P similar system. The main benefit of this system is better communication in developing world .e developing world.
Basically, TerraNet has researched this concept using peer-to-peer technology that enables users to speak on its phone without the need for a mobile phone base station.
The TerraNet technology works using phones adapted to work as peers that can route data or calls for other cell 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.
When a number is dialled a handset checks to see if the person being called is within range. If they are, the call goes through.While individually the phones only have a maximum range of 1km, any phone in between two others can forward calls, allowing the distance to double. This principle applied many times creates a mini network.
However this has created big problems with having enough available frequencies. The system can also be used to make calls to other TerraNet mesh networks via a net-connected PC fitted with an inexpensive USB dongle.
