Abstract:
1. A system comprising: a beam-weight generator configured to generate a plurality of beam weights including at least first and second sets of beam weights; and a beamformer coupled to the beam-weight generator and configured to apply the first and second sets of beam weights to signals in a cellular communication system providing coverage over a geographic region divided into cells arranged in overlapping first and second layers of cells having criteria optimized for communication by respective, distinct first and second types of user terminals, the criteria being reflected in the first and second sets of beam weights; wherein the criteria include satellite-antenna criteria, cell size and frequency reuse pattern, the satellite-antenna criteria include antenna gain and side-lobe suppression, and wherein the first layer of cells includes first-sized cells arranged in a first frequency reuse pattern, and is optimized for antenna gain, and the second layer of cells includes second-sized cells arranged in a different, second frequency reuse pattern, and is optimized for side-lobe suppression, and wherein the second-sized cells are smaller in size than the first-sized cells.
