The IEEE 802.11ad standard operates at the 60GHz band. The frequency band covers from 57.24 to 70.20 GHz, which is subdivided into 6 channels, and the bandwidth for each channel is 2.16 GHz. The Texas Instruments (TI) mmWave radar operates at 60-64 GHz spectrum. The mmWave radar is widely used for gesture and motion detection as well as in the automotive industry for short-range collision detection. IEEE 802.11ad supports up to 6.75 Gbps short-range communications. IEEE 802.11ad and the mmWave radar operate at overlapping unlicensed spectrums, and naturally, they interfere with each other. A systematic analysis of interference between a communication link and a radar is a complex problem because both devices benefit from multiple-input and multiple-output (MIMO) antenna systems with beamforming. This thesis presents an empirical analysis of the mutual interference between the IEEE 802.11ad communication link and the TI mmWave radar. The thesis presents the impact of the IEEE 802.11ad communication link on the mmWave radar coverage and precision. It studies and models mmWave radar interference on the IEEE 802.11ad wireless communication packet loss rate. The thesis develops and models interference based on the angle between the interfering antennas. It analyzes the effects of IEEE 802.11ad on the coverage and precision of the radar measured by the Cramer-Rao Lower Bound. The thesis uses a testbed for empirical measurement of the packet loss rate of the IEEE 802.11ad as a result of its interference with a mmWave radar.
