Open-source, software-based GSM cellphone network

It’s called the OpenBTS Project, and pundits are claiming it could reduce user costs to $2/month in the developing world.

OpenBTS is an open-source Unix application that uses the Universal Software Radio Peripheral (USRP) to present a GSM air interface (“Um”) to standard GSM handset and uses the AsteriskÂ® software PBX to connect calls. The combination of the ubiquitous GSM air interface with VoIP backhaul could form the basis of a new type of cellular network that could be deployed and operated at substantially lower cost than existing technologies in greenfields in the developing world.

In plain language, we are working on a new kind of cellular network that can be installed and operated at about 1/10 the cost of current technologies, but that will still be compatible with most of the handsets that are already in the market. This technology can also be used in private network applications (wireless PBX, rapid deployment, etc.) at much lower cost and complexity than conventional cellular.

Among other pilot project, OpenBTS networks were successfully deployed at Burning Man 2008 and 2009.

A small team of telecom industry veterans developed OpenBTS, an open-source, software-based cellphone network. Not only does it cost one-tenth as much as traditional networks, but carriers could charge callers about $2 per month and still make a profit.

How do I start my own GSM network, where do I start?
