Abstract(in English) Recently, the number of the mobile wireless LAN systems is increasing that includes mobile router or tethering. This suggests the possibility that more wireless LANs is crowded within a short distance than conventional assumption. Although commercially available AP decides channel to use with an original method that can avoid the interference and maximize throughput, most of them cannot deal with a large number of mobile wireless LAN systems. In this paper, the method of channel selection is investigated when numbers of APs become closer using commercially available APs. In this experiment, portable-type AP is used that selects channels which can reduce the number of contention between frames (intra-channel contention) as well as interference between channels (inter-channel interference). Moreover, because the number of interference between channels increases with many wireless LANs, the possibility is shown with calculation using measured data that neighbor channels are daringly used which cannot avoid interference between channels so as to increase total throughput of wireless LANs.
