Channel selection method and system based on WLAN wireless channel grading mechanism

Abstract

The invention provides a channel selection method and a channel selection system based on a WLAN wireless channel grading mechanism. The channel selection method comprises the following steps: step 1, scanning a current wireless channel, and making statistics about a wireless signal intensity indication values of each wireless router to a newly accessing wireless router on each wireless channel; step 2, working out the wireless channel with the lowest disturbance according to the wireless signal intensity indication values; and step 3, connecting to the wireless channel with the lowest disturbance. The channel selection method and the channel selection system are applicable to situations with complicated wireless environment and data disturbance among the wireless channels; when the router accesses the wireless network, the wireless router can automatically select an optimal wireless channel, so that the wireless data transmission efficiency is improved, the disturbance among the wireless channels is effectively reduced, the packet loss probability is reduced, and the quality of service of the wireless network is improved.

Description

technical field [0001] The present invention relates to a channel selection method and system thereof, in particular to a channel selection method and system based on WLAN wireless channel scoring mechanism. Background technique [0002] Currently, the wireless channel of the router is usually manually configured as a fixed value or directly initialized as a default channel. Correspondingly, when configuring the wireless channel mode, you can manually configure a wireless channel, or directly select a default value. Each wireless client communicates with the router using this channel. Since the wireless channel standards supported by different countries are different, it is necessary to select corresponding wireless channels according to the open wireless standards of each country. [0003] 802.11 wireless router technology supports 2.4G frequency band and 5G frequency band. There are 14 channels in the 2.4G frequency band, which is a relatively mature frequency band, so ...

Problems solved by technology

[0010] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a channel selection method and system based on the WLAN wireless channel scoring mechanism, which is used to solve the problem of wireless data packets in the complex situation of the existing wireless network environment. To solve the problem of unstable wireless network and high wireless packet loss rate caused by preempting wireless channels and large wireless interference, it uses a wireless channel scoring mechanism to select a better wireless channel for data transmission, thereby reducing wireless data during transmission. The probability of problems such as data frame retransmission, frame waiting, and frame collision caused by preempting the channel
