Abstract (in Japanese) (See Japanese page) 
(in English) Channel occupancy ratio is a key information to realize the efficient operation of the wireless system. In this paper, the relations between channel occupancy ratio and the throughput, and that between the channel occupancy and delay time, are evaluated by experimental studies for the basic data measurement for the heterogeneous wireless network. The experimental results show that there exists the threshold point of channel occupancy ratio over which channel occupancy ratio drastically increases. At such point, the throughput saturates and the delay time drastically increases. Moreover, in the case of many WLANs devices, e.g. over 12 WLANs, the throughput degrades due to the increase of channel occupancy ratio.
