Abstract :
A straightforward Over-The-Air (OTA) characterization method is proposed and conducted to characterize the MIMO performance of LTE devices. A “basic level” measurement in form of a sensitivity measurement in Downlink (DL) Transmit Diversity (TD) mode is used to evaluate diversity performance of User Equipment (UE) with multiple antennas in noise-limited scenarios. An “advanced level” measurement in form of throughput measurements in Spatial Multiplexing (SM) modes is used to characterize peak performance of UE in MIMO-favourable scenarios. Experimental results are presented for an E-UTRA band 7 USB dongle with three different arrangements of external antennas.
