Optimal Scheduling and Power Control for TDMA Based Point to Multipoint Wireless Networks

In TDMA-based point-to-multipoint rural wireless deployments, co-located base station radios and sector antennas are used to increase base station capacity. To achieve maximum capacity with limited availability of non-overlapping wireless channels, as many radios as possible are need to operate from different sectors on the same channel. However, operating co-located...
