Hi, "The OpenBTS Project is an effort to construct 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 Asterisk 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. " Last Friday, the VoIP Users Conference had David A. Burgess as our guest for an hour of discussion of one of his projects, OpenBTS (http://openbts.sourceforge.net/) which uses asterisk as a backend for the GSM network. Bookmarks to all the URL given on OpenBTS are here: http://delicious.com/voipusersconference The recorded conference can be hear or downloaded here: http://www.talkshoe.com/talkshoe/web/talkCast.jsp?masterId=22622 Enjoy!

They gave a presentation at the CCC around newyear, you might be able to find the videostream somewhere.

We follow up the project from some time. However from the practical point of view, has problems. The big one is regulation. In our country, a developing one, GSM bands are all licensed to the big operators, so you can not implemented a project like the OpenBTS, because you are no licensed. The big operators will never try to implement such kind of projects. And the regulators protects the big operators. Please, do not ask why. Regards Jorge Mendoza
