The 60 GHz band is being considered for many high bandwidth wireless applications. To support standards development for these applications, NIST has developed an untethered 60 GHz, 8×16 MIMO channel sounder. It employs a pseudorandom bit sequence with a bandwidth of 4 GHz. The sounder can precisely measure radio propagation channel characteristics such as path loss, small-scale fading, delay dispersion, absolutely delay, angle of arrival (AOA), angle of departure (AOD) and Doppler power spectrum. Its ability to measure the time dynamics of the millimeter-wave radio channel when untethered and in motion is unique. It employs electronically switched MIMO antenna arrays, a robot for moving measurements and an automated one dimensional positioner for precision measurements at fixed locations. Sounder performance is improved using pre-distortion filters and precision calibration of the RF and timing systems. Data showing initial AOD and AOD estimation error are presented along with initial test results for ground-plane reflection.
