Patent ID: 8000714

Claim:
An interference prediction apparatus that predicts a wireless channel in which channel interference will occur, the interference prediction apparatus comprising: a measurement unit that measures a received signal strength for each wireless channel; a prediction unit that predicts an interference area of a wireless channel in which channel interference will occur for each wireless channel on the basis of the received signal strength for each wireless channel; a wireless channel selection unit that selects a wireless channel to be used for wireless communication on the basis of the received signal strength for said each wireless channel and the interference area for said each wireless channel; a channel allocation unit that allocates the wireless channel selected by the wireless channel selection unit as the wireless channel to be used for wireless communication; and a calculation unit that calculates an interface-avoidance received signal strength for avoiding an occurrence of channel interference for said each wireless channel on the basis of the received signal strength for said each wireless channel and the interference area for said each wireless channel, wherein the wireless channel selection unit selects the wireless channel to be used for wireless communication on the basis of the interference-avoidance received signal strength calculated for said each wireless channel, wherein the wireless channel selection unit specifies a wireless channel corresponding to the least interference-avoidance received signal strength among corresponding wireless channels on the basis of the interference-avoidance received signal strength calculated for said each wireless channel, and calculates the specified wireless channel as the wireless channel to be used for wireless communication, and wherein the wireless channel selection unit selects the wireless channel to be used for wireless communication, in consideration of an interference-avoidance received signal strength of both neighboring wireless channels, when a plurality of wireless channels exists corresponding to the least interference-avoidance received signal strength.
