Embodiment Construction

[0036] In view of the problem that the RSSI value of the channel obtained by the arithmetic mean algorithm in the prior art cannot accurately reflect the quality of the channel, the embodiment of the present invention provides a method for determining the RSSI value of the channel. The process of the method is as follows figure 1 As shown, in the set scan period, for each channel to be adjusted, execute:

[0037] S10: The process starts.

[0038] First set four parameters, the RSSI of the AP is represented by the parameter ap_rssi; the current count value is represented by the parameter rssi_gap_cnt; the preset difference threshold value is represented by the parameter rssi_gap_max; the preset average value is represented by the parameter rssi_avg. The initial value of ap_rssi can be set as a value or a character, such as -1, -2, 0, a, b, etc., rssi_gap_max and rssi_avg can be set according to actual needs, or determined by statistical results. The scan period can be set acco...

Abstract

The invention discloses a method and a device for determining an RSSI (Received Signal Strength Indicator) value of a channel, and access point (AP) equipment. The method comprises the steps that A, an RSSI value in a received message is acquired, whether a current RSSI value of an AP is an initial value is determined, if so, Step D is executed, and if not, Step B is executed; B, an absolute value of a difference between the current RSSI value of the AP and the acquired RSSI value in the message is calculated, whether the absolute value is greater than a preset difference threshold value is determined, if so, Step D is executed, and if not, Step C is executed; C, the RSSI value of the AP is readjusted according to the current RSSI value of the AP, the acquired RSSI value in the message and a preset average value; and D, the acquired RSSI value in the message serves as the current RSSI value of the AP. With the adoption of the scheme, the RSSI value of the AP can be determined more precisely.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and access point device for determining a received signal strength indication (RSSI) value of a channel. Background technique [0002] With the rapid development of wireless communication network technologies and the rapid growth of services, available spectrum resources are becoming less and less. However, most users and emerging wireless access technologies tend to prefer those limited and crowded frequency bands, which reduces the actual utilization of available spectrum resources. [0003] In the 802.11 protocol, an access point (Access Point, AP) and multiple stations (Station, STA) connected to the AP form a Basic Service Set (BSS). With the evolution of the 802.11 protocol, the channel has expanded from the original 20M to 40M, 80M, 120M, etc. These large bandwidths are formed by bonding several 20M, for example, 40M is formed by bonding tw...
