A Unified Approach for Uncertainty Analyses for Total Radiated Power and Total Isotropic Sensitivity Measurements in Reverberation Chamber

With the rapid development and explosive application of the Internet of Things (IoT) technology, IoT devices become ubiquitous and indispensable in people’s daily lives. IoT devices with various forms and massive production impose challenges on their over-the-air (OTA) testing. Nowadays, conducting OTA testing in an efficient, reliable, and cost-effective way has become an urgent demand for the IoT industry. Owing to the particular properties (e.g., low cost, high efficiency, and good repeatability) of the reverberation chamber (RC), it has become a popular OTA testing facility. This paper analyzes the statistical uncertainties of two fundamental metrics for IoT devices, i.e., the total radiated power (TRP) and the total isotropic sensitivity (TIS), measured in the RC. Based on the derived probability density functions (PDFs) and associate statistics, a unified approach for uncertainty analyses of TRP and TIS has been proposed, which can greatly facilitate the uncertainty characterizations in the OTA testing.
