Claim:
1. An apparatus including a system to facilitate wireless testing of a radio frequency (RF) multiple-input, multiple-output (MIMO) signal transceiver device under test (DUT), comprising: a structure defining interior and exterior regions and configured to allow placement of a DUT within said interior region and be substantially isolated from electromagnetic radiation originating from said exterior region; an electrically conductive signal path to provide a wired connection to said DUT and convey one or more electrical data signals between said interior and exterior regions; a plurality of antenna arrays, each of which includes multiple antenna elements, disposed at least partially within said interior region to radiate respective pluralities of phase-controlled RF test signals for wireless reception by said DUT; and RF signal control circuitry coupled to said electrically conductive signal path and said plurality of antenna arrays, and responsive to a plurality of signal data from said DUT related to said respective pluralities of phase-controlled RF test signals wirelessly received by said DUT and conveyed via said one or more electrical data signals, and to a plurality of RF test signals by wherein RF signal control circuitry receives said plurality of RF test signals via a plurality of conductive signal paths directly from the origin of said plurality of RF test signals, and said interior region contains the only over-the-air (OTA) signal environment between said DUT and said origin of said plurality of RF test signals.
