Over reliance on GPS ?

[Chip Fetrow]

I think you mean base stations.

Many digital networks are timed via GPS.  I was in that industry, and  
Nextel was sort of first as some cellular providers were going D-AMPS  
(TDMA) and Verizon and Sprint went CDMA. D-AMPS providers went to GSM  
(also a form of TDMA) which is also very dependent upon timing, or  
time slots.  They also use GPS.
