A method and device for antenna self-adaptation of a wireless access point

Abstract

The present invention provides an antenna adaptation method and apparatus for a wireless access point. The method includes the following steps that: a current service load situation is monitored, when the change of the current service load situation reaches a preset condition and / or a sampling interval time exceeds a preset time, service sampling data are obtained, and one of optional transmission link configurations is selected as a current transmission link configuration; the average service consumption of the current transmission link configuration is calculated according to N service sampling data, and is saved; a transmission link configuration with minimum average service consumption is determined as an optimal transmission link configuration; and a current transmission link configuration is determined according to the optimal transmission link configuration and the current optional transmission link configuration. According to the antenna adaptation method and apparatus for the wireless access point of the invention, the antenna configuration with the highest energy efficiency is selected automatically and intelligently according a current environment, so that the wireless access point can adaptively adjust the number of transmission links under different service environment requirements, and the reduction of the energy consumption of the wireless access point device can be realized under the premise that the throughput of a system is not affected.

Description

technical field [0001] The present invention relates to the field of wireless local area networks, in particular to a method and device for antenna self-adaptation of a wireless access point. Background technique [0002] In the next-generation WLAN standard, multiple-input multiple-output (MIMO) technology is widely used to achieve greater network throughput. Currently, a wireless access point (AP) can be configured with 2 or more antennas for communicating with its associated terminal equipment. [0003] With the rapid expansion of wireless local area networks, millions of wireless access points are deployed in different areas. Therefore, the problem of energy consumption of wireless access points has become increasingly prominent. One is to design an effective energy-saving strategy to save the energy consumption of wireless access points, and the other is to ensure that the throughput of the system is not affected while saving energy. In this context, periodic dormancy...

Problems solved by technology

[0006] 1. The existing periodic sleep solution mainly solves the problem of energy consumption waste during the idle period of the WLAN AP equipment (wireless local area network), and is not suitable for the non-idle period of the business

[0007] 2. The existing downlink power control scheme mainly achieves the effect of suppressing interference by reducing the average transmit power of WLAN AP equipment, but the energy saving effect is limited
