Isn't a major problem with CDMA-based sources that the networks they depend on are getting shut down?

GPS inside a building probably isn't going to work unless you have the

Look at CDMA NTP Servers like the EndRun Sonoma. They use the cellular 
network which requires accurate timing and has good building penetration.
