Abstract

Systems and methods for optimized telecommunications distribution are provided. For example, a distributed antenna system can include a master unit for transceiving signals with remote units operable for wirelessly transceiving signals with mobile devices in a coverage area. A self-optimized network analyzer can be in a unit of the distributed antenna system. A self-optimized network controller in the distributed antenna system can output commands for changing operation of a component in the distributed antenna system in response to analysis results from the self-optimized network analyzer. In some aspects, the master unit includes base transceiver station cards for receiving call information in network protocol data from a network and for generating digital signals including the call information from the network protocol data for distribution to the remote units.
