Problems solved by technology

[0003] However, limited by the size of the deployment site, the distance between the more APs will be relatively short. Since the non-overlapping channels in the 2.4GHz frequency band are limited, in the standard 802.11n protocol, the interference outside the channel is known to be 20dBr, which means that when the distance between the APs of two adjacent channels is too close, they will interfere with each other, and the adjacent channel interference at this time will seriously affect the performance of the entire network
[0004] Therefore, in high-density user scenarios, it is necessary to optimize the services provided by APs. The existing optimization solutions are mainly realized through antenna technology and software optimization technology; by using antennas with high gain and excellent directional performance, each AP can only cover In the area within the ant

Abstract

Embodiments of the invention provide a wireless signal transmission method and an AP (access point). The method comprises the steps as follows: extracting signals of the working channel of a first wireless chip among wireless chips, and filtering interference signals of the working channel; adjusting the signal attenuation value according to the information between the first wireless chip and the other wireless chips or the information of a client; and processing the extracted signals according to the signal attenuation value. According to the wireless signal transmission method and the AP provided by the embodiments of the invention, multiple wireless chips working on different channels can be integrated in the same AP to provide high capacity, so that wireless service can be provided for a scene with high user density, and multiband wireless signal transmission is realized. Moreover, the signal attenuation value is adjusted according to the information between the wireless chips or the information of the client, the power of the signals is adjusted according to the signal attenuation value, and therefore, mutual interference between the wireless chips is reduced, and the performance of the wireless network is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless signal transmission method and a wireless access point (WirelessAccessPoint, AP). Background technique [0002] Most of the current APs are dual-band APs, that is, one AP integrates a 2.4G wireless network card and a 5G wireless network card. In order to provide services for areas with high user density, such as stadiums, theaters, conference centers, etc. Deploy more APs for support. [0003] However, limited by the size of the deployment site, the distance between the more APs will be relatively short. Since the non-overlapping channels in the 2.4GHz frequency band are limited, in the standard 802.11n protocol, the interference outside the channel is known to be 20dBr, which means that when the distance between the APs of two adjacent channels is too close, they will interfere with each other, and the adjacent channel interference at this time will seri...
