Wireless access point working channel selecting method and device

Abstract

The invention provides a wireless access point working channel selecting method and a wireless access point working channel selecting device. The wireless access point working channel selecting method comprises the following steps of: periodically transmitting broadcast signals outwards from an AP which is positioned in a working state; determining the interference level of an adjacent AP according to the signal strength by the AP receiving the broadcast signals; calculating the channel spacing between the working channel used by the adjacent AP and the working channel used by the AP; determining the corresponding interference degree according to the channel spacing and the preset channel spacing and an interference degree comparison table; multiplying the interference level by the interference degree to obtain the distribution information of the interference value; and selecting the working channel with the minimum interference value according to the interference distribution information. The wireless access point working channel selecting method and the wireless access point working channel selecting device can reduce the channel interference and improve the system capacity, does not need to occupy a common channel, avoids the resource waste, can be applied to the common fat AP framework and thin AP framework in the wireless local area network simultaneously, and has wide applicability.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless local area networks, and in particular to a method and device for selecting a working channel of a wireless access point (Access Point, AP for short). Background technique [0002] The existing wireless local area network is divided into a thin AP (Fit AP) architecture and a fat AP (Fat AP) architecture. figure 1 It is a schematic diagram of the structure of the existing thin AP architecture. As shown in the figure, each AP in the thin AP architecture is connected to a wireless access controller (Access Controller, AC for short) through the network, and the AP is only responsible for the wireless signal receiving and sending, all switching logic or network routing are completed by the AC. Multiple ACs can be connected through routers; ACs and APs can be connected through switches. [0003] figure 2 It is a schematic structural diagram of the existing fat AP architecture....

AI Technical Summary

Problems solved by technology

However, according to the existing wireless local area network standards, the total number of available channels is very limited, because the common channel is only used for channel allocation negotiation, and cannot provide services for customers, thus causing a waste of channel resources
