In this paper, the impact of user mobility on the performance of random beamforming (RBF) is studied for possible practical scenarios of millimeter wave (mmWave) broadcast downlink systems. Both mathematical modeling and simulation scenarios' results were investigated to estimate the upper bound of the degradation in the overall system throughput that results from the mobility of users in a small cells systems. Different possible factors that can affect the throughput are taken into consideration, which include the user location, direction of movement, speed, and the beam angle. Simulation results show that for all the typical mobility cases (walking, running, biking, and riding a car), the degradation in performance resulting from user mobility is marginal, while the Base Station (BS) will be able to deliver at least one message after each beamforming training period with high probability exceeding 99.99% theoretically and more than 96% in the worst case simulations.
