The reason many cell sites went to GPS for time and frequency synchronization is that in many cases it was either less expensive or only possible to backhaul the cell site traffic to the MTSO (Mobile Telephone Switching Office) via microwave radio rather than wireline copper or fiber carrier.
That microwave backhaul did not always provide sufficiently precise phase and frequency reference needed at the cell site. -- Tom, N5EG _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
