Abstract

Optimizing performance between a wireless distribution system (WDS) and a macro network(s). In this regard, a macro network optimization system is configured to detect a performance indicator(s) between a WDS and a macro network and optimize the performance of the macro network based on the detected performance indicator(s). The macro network optimization system analyzes a macro network performance report provided by the macro network and/or a WDS performance report provided by the WDS to detect the performance indicator(s) between the WDS and the macro network. The macro network optimization system reconfigures operations of one or more macro network elements to optimize performance between the WDS and the macro network based on the detected performance indicator(s). By detecting and optimizing performance between the WDS and the macro network, capacity, throughput, and/or coverage of the WDS and the macro network can be improved, thus providing better quality of experience (QoE).
