The invention discloses a method for improving the anti-interference capability of wireless communication, communication equipment and a storage medium. The method comprises the following steps: S1, detecting interference characteristics of a current wireless channel, and judging an interference level of the current wireless channel according to the obtained interference characteristics; and S2, adjusting the anti-interference capability according to the interference level of the current wireless channel. According to the invention, a data transmission frame interval with the highest priority is adopted, CCA detection before data transmission is closed, a burst mechanism is adopted, NAV occupation time of equipment data is prolonged, and an interference avoidance mechanism is adopted, so that the anti-interference capability of equipment can be improved to a great extent, the time delay of the data is reduced, and the transmission efficiency of wireless data of the equipment is improved; and meanwhile, by dividing the interference levels, a corresponding anti-interference mechanism is executed according to the interference level of the current wireless channel, so that influences on other equipment are avoided, and the invention can flexibly aim at different application scenes.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for improving the anti-interference capability of wireless communication, communication equipment and a storage medium. Background technique [0002] With the continuous popularization of intelligent devices, more and more devices are connected to other devices or interconnected using WIFI. These intelligent devices generally use the IEEE802.11 standard protocol to achieve communication. Wireless transmission technology based on IEEE 802.11 has been widely used due to free spectrum resources and simple equipment deployment. [0003] Based on IEEE 802.11 wireless transmission technology, since the data sent by the device adopts the free competition method, as more and more devices are deployed, when there are a large number of devices and data in the network, the data transmission bandwidth will decrease, and the data transmission The increase in d...
