Problems solved by technology

[0003] The current practice is to use dual-channel or multi-channel to avoid competition and interference, that is, to use the data channel to send and receive data, and to use the control channel to send and receive control signals. When the amount of data in each communication is small, it is easy to cause more control signals. load

Embodiment 1

[0036] Embodiment 1. A power control method, such as figure 1 shown, including:

[0037] S101. Obtain the location information of each AP in the predetermined area;

[0038] S102. For each AP, calculate a first distance between the AP and an AP closest to the AP according to the location information;

[0039] S103. Calculate the critical maximum transmission power of each AP according to the first distance of each AP, the critical maximum transmission power of the AP is: the signal transmitted by the AP will not be within the first distance from the AP. The maximum transmit power that causes interference at the location;

[0040] S104. Send a power control message including the critical maximum transmit power of the AP to each AP respectively.

[0041] In this embodiment, the predetermined area can be defined according to the desired geographical scope of management and adjustment, such as but not limited to delineating the predetermined area by means of coordinate values ​...

Embodiment 2

[0066] Embodiment 2. A power control device, such as figure 2 shown, including:

[0067] Transceiver module 21, used to obtain the location information of each AP in the predetermined area;

[0068] The first calculation module 22 is configured to, for each AP, calculate a first distance between the AP and the AP closest to the AP according to the location information;

Abstract

The invention provides a power control method and device. The method includes the steps that position information of each wireless AP in a preset area is acquired; for each AP, a first distance between the AP and the closest AP is calculated according to the position information; the critical maximum transmitting power of each AP is calculated according to the first distance of the AP, wherein the critical maximum transmitting power of the AP is the maximum transmitting power capable of preventing signals transmitted by the AP from causing interference at the position the first distance away from the AP; power control massages containing the critical maximum transmitting power of all the APs are transmitted to the APs respectively. The power control method and device can reduce interference caused by dense WiFi distribution.

Description

technical field [0001] The present invention relates to the network field, in particular to a power control method and device. Background technique [0002] The public WiFi provided by the operator uses the ISM (Industrial Scientific Medical, industrial, scientific, medical) working frequency band in the wireless local area network. In this frequency band, the frequency bands that do not interfere with each other and do not overlap each other are very limited. For a high-density WLAN (Wireless Local Area Networks, wireless local area network), the same channel occupies different APs (Access Point, wireless access point) , the transmitting areas of these APs can easily overlap, and as a result, AP signals back off from each other, thereby degrading performance. Especially within 100 meters of AP radiation, if many APs are concentrated, the influence of this mutual interference will be very obvious. For example, in Shanghai Hongqiao Railway Station, there are many shops, and...
