Abstract

A communication system comprises a wireless access node having a plurality of ports and a control system. The wireless access node is configured to exchange wireless communications over the ports with wireless communication devices that are individually identified by device identifiers. The control system is configured to individually allocate the wireless communication devices into categories based on the device identifiers and determine one of the categories having a majority of the wireless communication devices. The control system is configured to configure the ports of the wireless access node to utilize a MIMO 2T2R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a first data rate capability, and to configure the ports of the wireless access node to utilize a MIMO 4T4R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a second data rate capability.
