Power savings in mobile networks by dynamic base station sectorization

The authors conclude that instantaneous cell-load and buffer service-rate measurements can serve as input to various energy saving network algorithms. For example, such algorithms can control intelligent sleep modes in a mobile network, and can turn on and off radio resources according to the temporal and spatial variations of traffic. In particular, the authors demonstrate that underutilized 3-sector base stations can be reconfigured to omnicell base stations without significant service degradation in a network and that can save the power of two out of three radio units on typical 3-sector base stations.
