I'll gladly work with any cellphone operator with this. But I know how they feel about research in SA.
I have no malicious intentions though.
I dont think v2.3 is openly available. please check the (now moved) openbts wiki on GnuRadio for more info
This sounds great. How much does ICASA charge for 900mhz licence/spectrum? Where in SA would you buy the necessary equipment, for 10000 clients? 5Km radius. The cheapest equipment.
