Abstract

This paper presents an empirical analysis of the mutual interference between the IEEE 802.11ad communication link and the Texas Instruments (TI) millimeter wave (mmWave) radar in 60 GHz bands. We study the impact of IEEE 802.11ad communication link on the mmWave radar coverage and precision, and we model the impact of mmWave radar interference on the IEEE 802.11ad wireless communication packet loss rate. The paper investigates interference based on the angle between the interfering multiple input multiple output (MIMO) beamforming antennas of the two devices. We benefit from the Cramer-Rao Lower Bound for the analysis of precision degradations of the mmWave radar due to interference from the IEEE 802.11ad, and we benefit from empirical path-loss models to analyze the impact of the interference on coverage of the radar. We measure the empirical packet loss rate of the IEEE 802.11ad due to the interference from the mmWave radar in a laboratory testbed.
