Problems solved by technology
However, the above method is only applicable to the sector antenna of the base station, and the scene universality is not enough
In addition, the above method needs to obtain the antenna pointing information of the base station sector in real time, build a gain difference and direction correspondence table, and finally traverse the correspondence table to realize direction finding, which consumes a lot of data processing resources
[0004] To sum up, the direction finding method in the existing technology is not universal in scenarios, and consumes a lot of data processing resources

The invention relates to the technical field of communication, and discloses an RSSI (Received Signal Strength Indicator)-based client direction finding method, device and equipment and a storage medium, and the method comprises the steps: obtaining an RSSI value of a current position of each antenna and an RSSI value of an adjacent direction, and extracting a current position feature; performing feature matching according to the current position feature and a pre-configured RSSI local feature map to obtain a matching direction position of each antenna; recording the matching direction position of each antenna to a preset public directional diagram; and obtaining the final direction position of the client according to the direction position which is recorded most frequently on the public direction diagram. According to the method, client direction finding can be realized based on the multi-antenna RSSI distribution map, the processing speed of the direction finding process is high, and the method can be suitable for various scenes.
Description
technical field [0001] The present invention relates to the field of communication technology, and in particular to an RSSI-based client direction finding method, device, equipment and storage medium. Background technique [0002] Most household wireless routers use omnidirectional antennas. In actual use, the antenna radiation is not ideally omnidirectional, but there are dominant and inferior radiation directions. If the position and direction of the client relative to the antenna can be obtained, and the dominant direction of antenna radiation is aligned with the client, the performance and experience of the client can be improved to a certain extent. Therefore, how to use general-purpose equipment to perform wireless direction finding with as little resource dependence as possible is a research hotspot in the field of wireless direction finding. [0003] At present, the Chinese patent (application number CN200710092805.3) discloses a single-antenna terminal direction fi...
