Think about it in this way.
Each GSM (don’t know about CDMA’s)
Base Transceiver Station costs around 100,000 USD to set up, probably much more
for CDMA
So if what I said can be technically
implemented we can have a far cheaper mobile infrastructure (not talking about the
licensing stuff)
If that is applied to the other equipments
involved in a mobile network (like the BSC, HLR and the MSC), think how cheap
would that be. I am sure there are many more advantages of setting up such a
system.
Am not also a GSM/CDMA guy but I happened
to work for an ISP that is also offering mobile phone services and that made me
ask if it is possible to do it.
Thanks

I'm very curious to know why you want to do
that? While reusing SIM-identities on various access control points make
sense if you have customers with SIM (a WLAN/3G phone could then easily roam on
a service provider WLAN footprint, pending support for it in the phone, i.e.
pulling out SIM-data to be used in 802.1x), I cannot really see the reason for
doing what you propose?! (I'm not a GSM/CDMA person, so pardon me for being
ignorant)

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
http://www.mah.priv.at/siptrust/doit/sim-summary.html
http://cvs.berlios.de/cgi-bin/viewcvs.cgi/ser/gsm_auth/
what do you think?
Thanks
