ABSTRACT:
Cells in a radio telephone scheme are covered by beam-spots generated by multi-beam antenna system. Forward communication channels follow mobile units as they move between beam-spots. Additionally, each cell is divided into zones based on the mobile traffic patterns within the cell. Typically, there will be a high density zone covered by many, small area beam-spots, a medium density zone covered by two or three medium sized beam-spots, and a low density zone covered by one large beam-spot. As the mobile traffic patterns change throughout the day, multi-beam antenna dynamically reconfigures the zone and beam-spot layout for each cell, thereby keeping a nearly optimal zone and beam-spot configuration despite varying mobile traffic patterns.
