Wireless device and wireless communication method
First Claim
1. An electronic apparatus corresponding to a hub communicable with at least one terminal corresponding to a node via a first channel of a control channel and a second channel of a data channel, the electronic apparatus comprising:
- transmission circuitry configured totransmit a first beacon frame including “
1”
in a first field indicating a switch of the data channel and including a number of a third new channel in a second field indicating a channel number via the second channel informing the at least one terminal that the data channel will switch from the second channel to the third channel, andtransmit a second beacon frame including the number of the third channel in a third field indicating a data channel number via the first channel after the data channel is switched from the second channel to the third channel; and
reception circuitry configured to receive a data frame via the third channel after the data channel is switched from the second 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.
