Abstract (in Japanese) (See Japanese page) 
(in English) The human blockage problem is an open issue in next-generation wireless access networks using millimeter-wave (mmWave) communications.A base station (BS) handover system is proposed for solving the human blockage problem.We proposed a camera-assisted proactive handover system where cameras observe the mmWave communication region and handover is triggered by a camera image based blockage prediction.In this paper, we propose a mmWave throughput estimation scheme using an online machine learning algorithm and depth-image.The algorithm learns the relationship between depth images and measured throughputs, and estimates throughput from depth images.The scheme provides a quantitative metric for BS selection in handover without transmitting any control frames.
We conducted a proof-of-concept experiment by using the shelf IEEE 802.11ad mmWave wireless local area network devices and an RGB-D camera.The experiment confirmed that in a situation where the throughput is limited to 1 Gbit/s, the proposed scheme estimates throughput from a depth image with an RMS error of 114--178 Mbit/s in real time.
