Overview of state-of-the-art OTA measurements of wireless devices in reverberation chamber

We present an overview of the state-of-the-art over-the-air (OTA) measurements in reverberation chamber (RC) of wireless devices for the long term evolution (LTE) MIMO system based on our previous work. The measured throughput is well described by a simple and basic theoretical model based on an ideal threshold receiver, under different channel conditions and system configurations. Intuitive explanations to the measurement results are given. The reverberation chamber (RC) is shown to be an effective tool for active OTA tests, which extends its capabilities considerably compared to its original application for EMC tests.
