Abstract (en)

[origin: WO0139400A1] Described herein is a method of determining when propagation delays measured in both directions between two base stations <i>i</i> and <i>j</i> relate to the earliest path and not to a later path. Once synchronisation has been achieved, the measurement of the propagation delay is compared with predetermined limits and if falling within those limits is stored. Subsequent measurements of propagation delay are also compared with the predetermined limits and are only stored if they fall within those limits and are better than the currently stored measurement.
