摘要

An access system for a wireless local area network is provided. The access system initiates operation in a first frequency band of a plurality of frequency bands of the wireless local area network to provide one or more wireless client devices of the wireless local area network with access to a wireless wide area network. The access system also processes one or more association requests received in the first frequency band to identify one or more associated wireless client device. The access system also determines whether each of the one or more associated wireless client devices supports a second frequency band. The access system also sends a request to the one or more associated wireless client devices to transition from the first frequency band to the second frequency band based on determining that each of the one or more associated wireless client devices supports the second frequency band.

說明書

Association module 242 may include instructions to grant access to wireless local area network 110 in response to an association request, such as from wireless client device 114. Association module 242 may include instructions to associate with wireless client device 114 to access wireless local area network 110 based on authentication of user account credentials. In example aspects, association module 242 may include instructions to send a notification of the association of wireless client device 114 to server 130. In some implementations, the association request includes a capability field associated with a wireless client device (e.g., 114) that sent the association request. In some aspects, the association module 242 receives an association request from each wireless client device within a range of the wireless access point 116. The wireless access point 116 may process each association request. The wireless access point 116 may then, after a given amount of time, assess the capabilities of each of the wireless client devices that successfully associated with the wireless access point 116. These capabilities may be determined from the capability field, or known from history if that device had a prior association with the wireless access point 116. In some aspects, the wireless access point 116 may determine the capabilities of a wireless client device by trial and error with band switching.
