Problems solved by technology

[0005] The purpose of the present invention is to provide a dual-frequency WiFi intelligent switching algorithm based on 2.4G adaptive threshold, which mainly solves the problem that the WiFi frequency switching threshold in the prior art is a fixed value. When the dual-frequency signal strength value reaches the threshold at the same time, the wireless terminal No frequency point can be connected or repeatedly switched between two frequency points, causing the wireless terminal to fail to use the network normally and affecting the user's online experience

Embodiment

[0024] Such as figure 1 As shown, a kind of dual-band WiFi intelligent switching algorithm based on 2.4G adaptive threshold disclosed by the present invention comprises the following steps:

[0025] (S10) Determine whether the terminal is a wireless dual-band terminal device supporting the 802.11v wireless network protocol, if so, enter step (S20); otherwise, do not do any processing.

[0026] (S20) When the wireless terminal associates or scans WiFi, it sends a request command such as a prob detection request frame to the two frequency points of the 2.4G connection frequency point and the 5G connection frequency point. The difference Δr of the current signal strength of the frequency point.

[0027] (S30) According to the positive and negative relationship of Δr, determine the dynamic threshold value R (2.4) of frequency switching of WiFi at the 2.4G connection frequency point of the wireless terminal. If Δr≥0, then R(2.4)=Δr+R(5)+X; if Δr<0, then R(2.4)=R(5)+X, where R(5) ...

Abstract

The invention discloses a double-frequency WiFi intelligent switching algorithm based on a 2.4 G adaptive threshold value. The algorithm is used for wireless double-frequency terminal equipment supporting an 802.11 v wireless network protocol. By dynamically setting a frequency cutting threshold value of WiFi of a wireless terminal on a 2.4 G connection frequency point and fixedly setting the thefrequency cutting threshold value of the WiFi of the wireless terminal on a connection frequency point, so that the wireless terminal can be successfully switched to a proper frequency point when theWiFi needs frequency cutting, and meanwhile, the wireless terminal is ensured not to be switched back and forth at two frequency points. It is guaranteed that the routing device or the AP can have onefrequency point to be provided for the wireless terminal to be connected, and the user experience under double-frequency WIFI frequency switching is improved. Therefore, the routing equipment or theAP can process the switching of different terminals more smoothly, and the switching of the wireless terminal is smoother. Therefore, the algorithm has very high use value and popularization value.

Description

technical field [0001] The invention relates to a WiFi intelligent switching algorithm, in particular to a dual-frequency WiFi intelligent switching algorithm based on a 2.4G adaptive threshold. Background technique [0002] At present, WiFi frequency switching in the market is based on the RSSI (received signal strength) received by the wireless terminal by the routing device or AP (Access Point, that is, wireless access point) as the threshold for frequency switching. When the strength r(2.4) is higher than the 2.4G frequency switching RSSI threshold R(2.4) of the routing device or AP, it is required to switch to 5G; when the signal strength r(5) of the wireless terminal on 5G is lower than the routing device or When the 5G threshold R(5) of the AP is reached, it is required to switch to 2.4G. [0003] However, the 2.4G and 5G frequency switching thresholds used in the market are both fixed thresholds. There is a defect. When 5G is weak and 2.4G is strong, at the same loc...
