Fast Method for OTA Performance Testing of Transmit-Receive Cofrequency Mobile Terminal

Abstract

This paper provides a novel method for measuring of a wireless user equipment, when the equipment uses the same frequency for both transmitting and receiving. The proposed method is based on the fact that the total radiated power (TRP) and the total isotropic sensitivity patterns are complementary for transmit-receive cofrequency mobile terminals. Thus, the proposed method only requires a full TRP test and an accurate efficient isotropic sensitivity test to complete a total OTA performance measurement, resulting in improved test accuracy and decreased measurement time compared to the traditional test method defined in the OTA testing standard. The proposed method is suitable for OTA testing of transmit-receive cofrequency and single-input single-output radio systems, such as cellular communication, Wi-Fi, ZigBee, and Bluetooth.
