SYSTEM AND METHOD FOR PERFORMANCE ENHANCEMENT IN HETEROGENEOUS WIRELESS ACCESS NETWORK EMPLOYING DISTRIBUTED ANTENNA SYSTEM

摘要

A system and method for dynamically optimizing the performance of indoor distributed antenna systems (8) communicating with user equipment (16) is disclosed. The user equipment evaluates information describing downlink signals such as the downlink data rate, the quality of the received signal and the location of the user equipment. The service module 30 collects this information and determines the optimized power level of each of the antenna units 20. [ The service module 30 may optimize only one antenna unit power level or a subset of antenna units in the distributed antenna system 8 in one preferred embodiment. At this time, one or more of the antenna units 20 transmit downlink signals at optimized power levels. The optimized power level may be lower than the initial power level in one preferred embodiment. In another aspect, the system enhances the performance of multiple carrier base stations 300.
