ration is required and all that is needed is to connect the Base Station to a GPS.
When the Base Station detects that a 1 pps GPS signal is present then it will synchronize its TDD gate to
the GPS and if it does not detect a 1 pps GPS signal then it will s
In the event that there are co-
located multiple Base Stations, it is important to synchronize all the Base
Station to a 1 pps GPS such that this will co

This is especially important if neighboring Base Stations are set to operate on overlapping
or identical frequency channels.
