Abstract
There is disclosed a launch delay controller, for use in a wireless messaging system having a defined coverage area. The launch delay controller controls the transmission of paging messages from a plurality of transmitters in the wireless messaging system. The launch delay controller comprises: 1) a memory capable of storing a) a delay spread associated with a selected point in the coverage area between a first signal transmitted by a first of the plurality of transmitters and a second signal transmitted by a second of the plurality of transmitters, and b) distances between the selected point and the first and second transmitters; and 2) a processor capable of determining from the delay spread and the distances an offset delay, wherein the offset delay is used by the first transmitter to delay a transmission of the first signal with respect to a transmission of the second signal, the delayed transmission of the first signal thereby reducing the delay spread.
