  • Publication number: 20230019184
    Abstract: In a control apparatus, a channel selection control unit selects a “switching destination channel pair” from among a plurality of “switching destination channel pair candidates” in a plurality of radio channels. The “switching destination channel pair” is selected based on the degree of similarity between two BSSIDs of two radio channels constituting the currently-connected radio channel pair, and a plurality of degrees of similarity each of which is a degree of similarly between two BSSIDs of two radio channels constituting a respective one of the plurality of switching destination channel pair candidates. A channel switching control unit performs control so that radio units connect to the switching destination channel pair selected by the channel selection control unit.
