Embodiment Construction

[0062]The present invention will be further described below with specific embodiments in conjunction with the accompanying drawings.

[0063] The present invention discloses a power control method of an AP, the first embodiment of which is shown in Figure 1, comprising the following steps:

[0064] S101. Determine whether the AP uses the same channel as the adjacent AP, and if yes, go to step S102.

[0065] In a WLAN, due to limited channel resources, APs usually have to select the same channel to use, thus generating CCI (co-channel interference, co-channel interference) between AP fingers. The AP power control method of the present invention uses the neighboring APs that use the same channel as the AP as the reference objects for power control. As for adjacent APs that use different channels from the AP, it is not necessary to consider the impact of the AP's power control on them, and the AP should try to work at the maximum power allowed by the network to ensure sufficient...

Abstract

The disclosed power control method for AP comprises: combining distance factor to determine the reference AP, then according to the effect on reference AP led by power adjustment, initiating the AP emission configuration, then continual dynamic controlling. This invention can reduce channel interference, and makes the WLAN more reliable.

Description

technical field [0001] The present invention relates to the field of wireless local area networks, in particular to an AP (Access Point, access point) power control method and equipment. Background technique [0002] With the increasing development of wireless network technology, a WLAN (Wireless Local Area Network, wireless local area network) capable of providing a local area network wireless connection service is more and more widely used. AP is a wireless transceiver device in WLAN, which converts the data received from the wired network into wireless signals for transmission, and converts the received wireless signals into data and forwards them to the wired network. [0003] At present, WLANs based on the IEEE 802.11 specification have been widely used. Because users lack professional knowledge of WLAN network deployment during use, and wireless signals are greatly affected by factors such as the environment, co-channel or adjacent channel interference is difficult to...
