Over-the-Air Testing of Cellular Large-Form-Factor Internet-of-Things Devices in Reverberation Chambers *

We demonstrate the applicability of the reverberation chamber for over-the-air testing of power-based metrics for cellular-enabled wireless internet-of-things devices. A recent industry-sponsored round robin illustrates agreement between labs to within the industry specified limits of ± 2 dB for radiated power and ± 2.3 dB for receiver sensitivity.
