Abstract

A wireless communication device to improve multipath environments for multiple-input multiple-output (MIMO) wireless networks comprises a wireless communication transceiver and a processing system. The wireless communication transceiver is configured to receive MIMO performance information for a plurality of locations of a premises. The processing system is configured to process the MIMO performance information to determine individual ranks associated with each of the locations, wherein higher ones of the ranks indicate better MIMO performance, compare each of the individual ranks to a threshold to determine a group of suboptimal locations of the plurality of locations that have ranks falling below the threshold, and process the suboptimal locations with an in-building geometry of the premises to identify at least one location to install a scattering agent.
