Problems solved by technology

[0012] However, in the method of automatic channel selection by the AP, since the AP does not understand the entire WLAN network topology, each AP only selects the channel from its own perspective and pursues its own channel optimization, which may cause key APs (such as the central AP in the WLAN network area) ) cannot obtain channel resources more preferentially

Abstract

The invention discloses an AP channel selection device, method, AP, central controller, software and equipment, wherein the AP channel selection device includes: a self-priority information processing module, which is used to obtain an access point after the access point is started The priority parameter corresponding to the channel itself; the channel allocation module is used to obtain the priority parameter of the access point, and after judging the priority of the access point relative to the channel according to the obtained priority parameter, allocate the channel to the For an access point that has not been allocated to a channel, the access point that has been allocated to the channel has the highest priority in the allocated channel compared to other access points that have not been allocated to the channel after startup. By judging the priority of APs and assigning channels to APs with high priority, the present invention effectively avoids local optimization of AP channel allocation, does not rely on RF planning tools, and realizes automatic, efficient, and globally optimized AP channels The choice is simple.

Description

technical field [0001] The present invention relates to the access point in WLAN (Wireless Local Area Network, wireless local area network), particularly a kind of access point and channel selection method thereof, make key AP (Access Point, access point) can preferentially obtain RF (Radio Frequency , radio frequency) resources. Background technique [0002] WLAN can provide wireless connection service of local area network. In WLAN, AP is an important component device of wireless local area network. The incoming wireless signal is converted into data and forwarded to the wired network. [0003] AP needs to work on a certain channel when performing wireless signal sending and receiving, and provide physical channel for user access. g stipulates that the number of available channels is 11, while b / g has only 3 non-overlapping channels. [0004] In principle, adjacent APs should use non-overlapping channels as much as possible. However, in an enterprise WLAN network, there...
