Embodiment Construction

[0056] Referring to the accompanying drawings, methods and apparatus according to preferred embodiments will be described.

[0057] First, refer to figure 1 , an example of a user's premises including a wireless access point device will be described, which shows an overview of a user's premises with a wireless LAN system.

[0058] Within a user's premises 10, such as a user's home or office environment, a wireless local area network (WLAN) 13 is provided by a wireless access point (WAP), which is typically provided as part of a combined device that also Provides the functionality of a modem and the functionality of a router. Such a device may be referred to as a "home hub" or "hub", or as a "gateway device", but is generally referred to herein as a wireless access point device 20 .

[0059] refer later figure 2 , the functional modules of an exemplary wireless access point device will be described in more detail, but its normal function as a wireless access point device o...

Abstract

Methods and apparatus are disclosed for controlling wireless communication between a first wireless access point and one or more user devices, the first access point having an interface for communication with the user devices on one or more wireless communication channels in a predetermined frequency range, and also being configured to communicate with one or more other wireless access points. The access points each have a radar detector operable to detect possible radar signals within the frequency range, and are configured to provide information indicative of whether or not possible radar signals have been detected. The first access point receives communications relating to information provided by the other access points, and starts or stops wireless communications with its user devices on a particular channel based on whether or not it has detected possible radar signals together with whether or not the other wireless access points have detected possible radar signals.

Description

technical field [0001] The present invention relates to methods and devices for controlling wireless communications. In particular, embodiments of the invention relate to wireless access points and techniques that enable wireless access points to perform "Dynamic Frequency Selection," or DFS. Background technique [0002] In wireless networking, a wireless access point ("wireless AP" or "WAP") is used to create a wireless local area network ("wireless LAN" or "WLAN") to allow multiple wireless / Devices that communicate using radio transmissions within a local geographic area. Wireless access points that generate WLANs are typically based on the IEEE802.11 family of wireless protocols (more commonly known as WiFi or Wi-Fi TM ) to operate. [0003] WLANs can typically have a range of tens of meters, which is usually large enough to cover a home or small office. Despite possible range, the exact coverage and data rate achievable at a given location depends on transmit powe...
