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

This invention discloses one AP signal channel selection device, method, AP, central controller, software and device, wherein, the AP signal channel selection device comprises the following parts: self priority information process module to get interface point self and signal channel relative priority parameters after interface points started; signal channel align module to get interface point priority and to judge interface points priority according to the parameters and to align the signal channel into interface points of the channels.

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...
