Abstract
A system and method for dynamically optimizing the performance of indoor distributed antenna systems communicate to user equipment is disclosed. The user equipment measures information describing the downlink signals such as the downlink data rates, the quality of the received signal, and the location of the user equipment. A service module collects this information and determines an optimized power level for each of the antenna units. The service module may optimize only one antenna unit power level or a subset of the antenna units within the distributed antenna system in a preferred embodiment. One or more of the antenna units then transmits downlink signals with the optimized power levels. The optimized power level may be less than the initial power level in a preferred embodiment. As a result, the performance of the indoor distributed antenna systems is enhanced.
