A method and device for saving energy in a wireless local area network

Abstract

The invention discloses an energy-saving method and an energy-saving device of a wireless local area network. The energy-saving method and the energy-saving device of the wireless local area network are applicable to the wireless local network which comprises a wireless controller, a wireless access point and a webmaster server. The energy-saving method of the wireless local network includes the steps of collecting current information of access point (AP) equipment of a hot spot region at regular intervals by the wireless controller, judging whether a hot spot weak signal coverage mode is applicable or not according to the collected current information of the AP equipment of the hot spot region, adopting the hot spot weak signal coverage mode when the hot spot weak signal coverage mode is applicable, and adopting a hot spot strong signal coverage mode when the hot spot weak signal coverage mode is not applicable. According to the energy-saving method and the energy-saving device of the wireless local area network, under the condition that an application effect of the wireless local area network is guaranteed, consumption of the hot spots of the whole network is greatly saved.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method and device for saving energy in a wireless local area network. Background technique [0002] WLAN (Wireless Local Area Network, wireless local area network) provides a wireless connection service of local area network, which can provide high-speed wireless data access in a small range. It is one of the more popular technologies in the IT industry and is also a popular wireless access. Way. AP (Access Point, access point) is an important component device in the wireless local area network. converted into data and forwarded to the wired network. [0003] With the popularization of WLAN networks, a large number of wireless access point AP devices have been deployed, and the three major operators currently have more than one million access point APs working. For access point APs with different signals, the required power consumption also changes with the access of wirele...

Problems solved by technology

However, in the existing technology, always keeping the access point AP in working condition will waste energy and money

For example, a coffee shop hotspot coverage, there are almost no wireless users from 4:00 am to 10:00 am. During this time, all access points APs of the hotspot are always on standby, which is actually a waste of energy.
