Abstract
An MPAC OTA test system and method are provided that can be used to perform radiated testing of 5G BSs and 5G UEs. The arrangement and number of active probe antennas in the anechoic chamber can be selected based at least in part on a simulation of the channel model of the RC emulator to improve testing while also reducing the overall number of probe antennas that are needed and reducing the channel resources of the RC emulator of the MPAC OTA test system, thereby allowing the overall complexity and cost of the MPAC OTA test system to be reduced.
