1. A method of calibrating a local radio reference clock for a radio operating in a radio network having a network reference clock, comprising the steps of:
- (a) determining at the radio an offset between the local clock and the network clock;
(b) placing the local clock in a calibration mode;
(c) calibrating the local clock using a radio link to reduce the offset.
