"The task of running a cellular network has usually been reserved for major carriers. But now an open-source project called OpenBTS is proving that almost anyone can cheaply run a network with parts from a home-supply or auto-supply store. Cell-phone users within such a network can place calls to each other and--if the network is connected to the Internet--to people anywhere in the world.
The project's cofounder, David Burgess, hopes that OpenBTS will mean easier and cheaper access to cellular service in remote parts of the world, including hard-to-reach locations like oil rigs and poor areas without much infrastructure."
"Just about anybody can create an inexpensive cellular base station that routes calls all over the world."
