First Claim
1. An electronic apparatus, comprising:
- receiver circuitry configured to receive a first beacon via a first channel; and
control circuitry configured to;
specify a second channel according to channel information included in the first beacon;
change an operation channel of the receiver circuitry from the first channel to the second channel; and
change the operation channel from the second channel to the first channel if a first period has elapsed without receiving a second beacon via the second channel, whereinthe receiver circuitry is further configured to receive a third beacon via the first channel after the operation channel is changed from the second channel to the first channel, andthe control circuitry is further configured to specify a third channel according to channel information included in the third beacon, and change the operation channel from the first channel to the third channel.

Abstract
According to one embodiment, a wireless device includes a receiver configured to receive a first beacon signal via a first channel; and control circuitry. The control circuitry is configured to: analyze the first beacon signal to obtain channel information for specifying a second channel, change an operation channel of the receiver from the first channel to the second channel, and change, in a case of not receiving a second beacon signal via the second channel during a predetermined period of time, the operation channel of the receiver from the second channel to the first channel. The receiver is further configured to receive a third beacon signal via the first channel after the operation channel is changed from the second channel to the first channel.
