Wi-Fi router intelligent antenna user tracking method and system

Abstract

The invention discloses a Wi-Fi router intelligent antenna user tracking method and system. The method comprises the steps of: S1. receiving control message protocol response information sent by user equipment, and acquiring and recording a first round-trip delay; S2. rotating an antenna, and acquiring and recording a second round-trip delay; and S3. comparing the first round-trip delay and the second round-trip delay, rotating the antenna according to a comparison result, and acquiring and recording a new round-trip delay until the newly acquired round-trip delay is greater than a previously acquired round-trip delay. According to the Wi-Fi router intelligent antenna user tracking method and system disclosed by the invention, by using a directional antenna on a Wi-Fi router device, according to a round-trip delay of the user equipment and a router, an antenna angle is automatically calculated and regulated so as to achieve an optimal transmission angle and keep reliable and stable signal transmission always being established between the user equipment and the router. Moreover, according to the Wi-Fi router intelligent antenna user tracking method and system disclosed by the invention, the round-trip delay between the router and the user equipment is tested by a control message protocol; and the method is simple and effective and is very practical.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method and system for tracking users of smart antennas of Wi-Fi routers. Background technique [0002] With the continuous development of Internet technology, Wi-Fi communication has gradually become popular. In home life, a Wi-Fi router is usually used to implement Wi-Fi communication. At present, most Wi-Fi routers on the market use external omnidirectional antennas or built-in omnidirectional antennas, and the gain of the antenna is 0.5-5dB. When the above-mentioned Wi-Fi device transmits wireless signals through the antenna, due to the limited coverage area of ​​the signal, there may be problems of signal dead spots or unstable signal connection. There are two solutions to the above signal dead angle problem: one is to increase the signal transmission power, which requires a corresponding increase in the power amplifier or increase the output power of the power ...

AI Technical Summary

Problems solved by technology

However, when the Wi-Fi signal is transmitted in space, reflections will occur when encountering obstacles, resulting in multipath signals. Therefore, when calculating and comparing RSSI, sometimes the fluctuation of RSSI is relatively large, and it is difficult to accurately grasp the signal at a certain moment. intensity of the situation

On the other hand, the acquisition of the signal strength of the wireless router requires the receiving end to perform statistics and feedback, and the user terminal must install an additional application program to cooperate with it, which undoubtedly limits the application of this technical method to a certain extent
