1. In a microcellular digital communication system having one or more mobile transceivers and at least one stationary transceiver with at least one antenna element comprising a set of antennas for sending and receiving a data signal having a carrier frequency propagated between any of said mobile transceivers and said stationary transceiver through a channel having a plurality of paths, a method for limiting the maximum signal fading loss duration in said propagation channel to a predetermined threshold value, said method comprising the steps of:

  • coupling together said set of antennas creating a radiation pattern thereof; and

    modulating said radiation pattern of said set of antennas at a predetermined rate so as to average power of said data signal sent and received over said plurality of paths by said set of antennas, said predetermined rate being selected to reduce said signal fading loss duration below said predetermined threshold value over any of said plurality of paths in said system.
