An Adaptive Modulation Method for Wireless Router

Abstract

The invention discloses an adaptive modulation method for a wireless router. The method comprises steps as follows: (A1), wireless interference strength of current channels is scanned, and wireless interference parameter sets are obtained; (A2), the obtained wireless interference parameter sets are matched with a plurality of preset application scenes, and each application scene corresponds to one wireless interference parameter set; (A3), the application scenes are matched with the channels according to dynamic channel selection strategies to obtain the channels corresponding to the application scenes; (A4), the current channels are switched to the channels corresponding to the application scenes; (A5), preset time is delayed, and the step (A1) is conducted. According to the adaptive modulation method for the wireless router, the channels are correspondingly switched according to different performance requirements of the channels on different scenes, and the channel with the optimal performance under wireless interference of different degrees is selected from the current channels for wireless data transmission, so that the purpose of increasing the transmission rate is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to an adaptive modulation method of a wireless router. Background technique [0002] The wireless channel is the wireless "frequency band (Channel)", which is a data signal transmission channel using wireless signals as the transmission medium. The commonly used wireless standard IEEE 802.11b / g works in the 2.4-2.4835GHz frequency band, and these frequency bands are divided into 11 or 13 channels. In the IEEE 802.11b / g standard, there are 3 non-overlapping transmission channels, which are: channel 1, 6, 11 or 13, so these three channels are the main channels used in the wireless gateway device. [0003] Since the default setting of most wireless gateway devices is Channel1, it is easy to appear that there are more than two APs within the coverage area of ​​the wireless AP (Wireless Access Point, wireless access point), and it is necessary to set the channel for each AP. different frequen...

Problems solved by technology

[0004] However, since there is only one criterion for switching channels at present, which can only be adapted to one application scenario, the criterion is fixed in different scenarios, and the result of channel selection will be affected if the standard is too high or too low. It is impossible to accurately select the best channel, which affects the transmission rate of wireless data, and there is a problem of being too sensitive or too slow to respond to wireless interference
