Abstract

The invention discloses a message transmission method and device applied to a WLAN (Wireless Local Area Network) as well as network equipment. The message transmission method provided by the embodiment of the invention comprises the following steps that: after RRM (Radio Resource Management) is carried out for each time, an AP (Access Point) determines receiving sensitivity according to a minimum receiving power value and a sending power value, and receives a message according to the determined receiving sensitivity; and the AP can regulate the receiving sensitivity according to current conditions of receiving power and sending the power in real time, set the receiving sensitivity within a relatively proper range, and screen relatively multiple interference signals and relatively weak signals from user equipment, so that the receiving error package rate is reduced, and the frequency spectrum resource use ratio and the network throughput ratio can be improved.

Description

technical field [0001] The present invention relates to wireless communication, in particular to a method and device for receiving and sending messages applied to WLAN, and network equipment. Background technique [0002] The original intention of the Institute of Electrical and Electronics Engineers (IEEE, Institute of Electrical and Electronic Engineer) 802.11 specification is for home and small office applications. In this case, the transmit power of a single access point (AP, Access Point) is generally set to The maximum value that can be achieved (the relevant regulations are up to 100mw), and the receiving sensitivity is set to the lowest value that can be achieved, that is, the threshold of the received signal is set as low as possible (the relevant regulations are generally -85dBm), so that the AP can both Send signals to as many user terminals (STA, Station) (or handheld devices) as possible, and also receive weaker signals as much as possible, so as to improve sign...
