Abstract

A base station for use in a mobile communications network includes a frequency synthesizer for generating signals at desired frequencies and a packet data interface for transmitting and receiving packet data signals over a wide area network. The basestation is configured to determine an elapsed time since it last synchronized the frequency synthesizer to a master device. The basestation is also configured to request synchronization packet data signals from the master device when the elapsed time exceeds a predetermined holdover period.
