    Abstract: A method is disclosed for providing syntonisation, synchronization, position or some combination to a wireless base station, micro-cell, pico-cell, femto-cell or access point, by providing holdover backup in a GPS clock module via at least one interface between the GPS clock module and an external time or frequency reference. Switching between synchronization modes is designed to occur on the control side of the oscillator portion of the module rather than at the output of two oscillators. A corresponding GPS clock module apparatus is disclosed for providing holdover backup via at least one interface between the GPS clock module and external time or frequency references.

    Abstract: A method and apparatus for positioning one of a set of mobile antennas capable of receiving signals from GPS satellites, each mobile antenna being associated with corresponding mobile user equipment and capable of communicating with a base station, wherein the mobile user equipment receives and decodes signals from each GPS satellite, and communicates to the base station data enabling knowledge of the identity of each satellite and uncorrected mobile antenna position, the base station decodes signals through a base station antenna from each of the set of GPS satellites used by the mobile user equipment, computes an uncorrected range from each satellite to the base station antenna, and compares the uncorrected range from each satellite to the base station antenna with an actual range based on computed satellite positions and a known base antenna position, to provide systematic range errors for each of the set of GPS satellites, and the base station utilises a known relationship between range error and antenna position error to deduce a correction to the mobile antenna position.
