Abstract:
1. A method of a controlling apparatus, comprising: selecting a first communication apparatus, which has a higher load than a second communication apparatus, based on a load of a plurality of communication apparatuses; determining interference on a plurality of communication channels caused by a signal sent from an uncontrolled apparatus which is not controlled by the controlling apparatus; selecting a first communication channel from among the plurality of communication channels, whose interference is lower than that of a second communication channel, based on the determined interference on the plurality of communication channels; and allocating the first communication channel to the first communication apparatus, wherein, in allocating, the same communication channel as the first communication channel is allocated to a third communication apparatus in a case where the third communication apparatus is classified in the same load class as the first communication apparatus, and the first communication apparatus does not receive a signal from the third communication apparatus wirelessly and the third communication apparatus does not receive a signal from the first communication apparatus wirelessly, or another communication channel is allocated to the third communication apparatus in a case where either the first communication apparatus receives a signal from the third communication apparatus wirelessly or the third communication apparatus receives a signal from the first communication apparatus wirelessly.
