Abstract
MIMO test systems and methods are provided that eliminate the need for a wired connection between the test system and the antenna ports of the DUT, thereby eliminating the need to open up the housing of the DUT and risk damaging or destroying it. The MIMO test systems and methods also eliminate the need for an anechoic chamber, thereby eliminating the cost and space requirements associated therewith. A suitable non-anechoic, electromagnetically-shielded chamber can be used in the test system that is much less expensive and that has a much smaller spatial footprint than a typical anechoic chamber used in MIMO test systems.
