Abstract

Network element (300) with reference clock (302) is fixed to base station (102) with local clock (330) via asynchronous data transmission connection (312). Reference clock sends time stamp signal (308) over connection. Station (102) receives time stamp signal and calculates deviation of local clock time from reference time. Based on deviation, speed correction factor is output and applied to local clock. A frequency synthesizer (212) generates frequency based on the corrected local clock. An independent claim is also included for the method of performing frequency synchronization of base station.
