measurement uncertainty

Reverberation chamber (RC) is a metal cavity which is often used for EMC measurements. During the last couple of decades, RC has proved to be a useful tool for Over-the-air (OTA) measurements such as antenna efficiency, diversity gain, etc. A well stirred RC produces Rayleigh fading environment which is considered as a common test environment for testing and simulating performance of wireless devices such as mobile phones in GSM, WCDMA, UMTS and LTE frequency ranges.
