PROBLEM TO BE SOLVED: To provide a system and a method that dynamically optimize the performance of an indoor distributed antenna system DAS communicating with a user device.SOLUTION: User devices 16a-16c measure information, such as a downlink data rate, the quality of a reception signal, and the location of the user devices, to describe a downlink signal. A DAS service module 30 collects the information, and determines power levels optimized for respective antenna units 20a, 20d, 22a and 22d. The service module optimizes the power level of only one antenna unit or a subset of the antenna units within a distributed antenna system 8. Then, one or more antenna units among the antenna units transmit a downlink signal at the optimized power levels. In addition, the optimized power levels may be below an initial power level.SELECTED DRAWING: Figure 1 |
