Hi all serusers;

I have been using SER for a couple of years now (from 2004) and I have been really impressed. It has landed me more than 2 good jobs and when combined with Asterisk, you ask yourself what Telcos without it do!!!!

Given all SIP related software and ideas that are there, I have been asking myself this question:

Is it possible to design a GSM/CDMA Base Transceiver Station using Software Defined Radio (for signal acquisition and processing + some SER functions,)

A GSM switch (done through SER and/or Asterisk)

A GSM HLR,(Home Location Register and VLR, supposing that SER with GSM auth module act as such) which is I think a set of databases and some interfaces.

This may sound stupid but I thought maybe someone has thought abt sth like that?

The idea was provoked by these 2 links

Thanks
