Show HN: 1xBTS – Run your own CDMA network on an SDR
1xbts.orgThis is so sick! How'd you manage to get the specs for CDMA? Did you reverse engineer?
The specs are public from 3gpp2 (https://www.3gpp2.org/). I didn't have to reverse engineer but in the initial RF bringup, even with the specs, it took me a while and had to pick up some old CDMA test equipment to capture actual BTS signals to help me understand it better.
