Base apparatus, wireless communication channel changeover method, and wireless communication channel changeover program

摘要

A base apparatus for wireless LAN, includes: two or more wireless units having; communication means for communicating with a terminal through wireless channel, channel selection means, detection means for detecting noise level of received signal, determination means for determining received signal is wireless LAN signal of another; unit setting means for setting one of two wireless units as communication unit, and setting another as retrieving unit for retrieving optimal wireless channel; channel setting means for setting up wireless channel for communications; state detection means for detecting state of channel, based on outputs from detection means and determination means; retrieval means for retrieving optimal wireless channel, based on outputs from detection means and determination means, candidate channel setup means for setting optimal wireless channel; and switch control means for replacing wireless unit for communications for retrieving switched for communication, when retrieved wireless channel is better than that already used for communications.
