Abstract
A method of improving frequency accuracy of a clock unit adapted to clock a femtocell local cellular communication home base station is provided. The method comprising: providing a local cellular communication home base station having an oscillator adapted to operate as a clock therein, wherein at least one cellular communication device is camped thereto, and wherein the at least one camped cellular communication device is further in communication with at least one neighboring cellular communication base station which is associated with an oscillator adapted to operate as a clock therein; periodically applying a derivative operator over periodically obtained local communication parameters and periodically obtained neighboring communication parameters thereby generating derivative communication parameters over time; and correcting the accuracy of the frequency of the clock in the femtocell local cellular communication home base station using the derivative communication parameters over time.
