Abstract

Systems, processes, and structures allow enhanced near-field testing of the uplink and/or downlink performance of MIMO wireless devices (DUT), such as for any of product development, product verification, and/or production testing. Signal channels may preferably be emulated to test the performance of a device under test (DUT) over a range of simulated distances, within a near-field test environment. An enhanced process provides automated testing of a DUT over a wireless network, e.g. such as but not limited to a WLAN. The enhanced MIMO channel emulator may preferably be operated over a high dynamic range.

First claim

The invention claimed is:

1. A test system for testing multiple input multiple output (MIMO) devices, comprising:
a test chamber having an interior region defined therein for mounting a MIMO device to be tested, the test chamber comprising at least one power connection and at least one signal connection for the MIMO device;
an antenna matrix located within the test chamber, wherein the antenna matrix comprises a plurality of test antennas, wherein each of the test antennas corre…
