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

Wireless access point 116 and/or 126 is a network device and can include other network devices, such as a hub, a router, a switch, and/or a bridge. The network device may be a combination of network devices, such as a wireless router that includes a router, a switch, and a wireless access point. The network device can be a wireless router with a built in modem (e.g., cable modem) for example. Other network devices can also be utilized in implementations of the subject technology.

Wireless local area networks 110 and 120 can include, but are not limited to, a computer network that covers a limited geographic area (e.g., a home, school, computer laboratory, or office building) using a wireless distribution method (e.g., spread-spectrum or OFDM). Wireless devices 112 and 114 may associate with wireless access point 116 to access wireless local area network 110 using WiFi standards (e.g., IEEE 802.11). Some WiFi access points are mobile hot spots that provide, e.g., a WiFi-to-cellular bridge. This type of access point may be carried around by individuals or used in automobiles to provide mobile WiFi service. For example, wireless device 116 acts as a wireless access point (e.g., mobile hotspot), where wireless client devices 112, 114 and/or 122 may associate with wireless device 116 to access network 102 (e.g., LTE) using the WiFi standards.
