Over the air Calibration and Testing of Beamforming-Based Multi-Antenna Devices in Anechoic and Non-Anechoic Environments
TL;DR: In this article, a method for wirelessly calibrating/testing RF and digital components of a multi-antenna device under test includes the step of wirelessly transmitting a first signaling information between the device under-test and a device tester, indicating a calibration request.
