With the development of society and the advancement of technology, location-based services (LBS) are widely used in traffic navigation, logistics management and other fields, gradually expanding from outdoor scenes to indoor environments, from production services to life and entertainment. Its application prospects will be very broad. A necessary prerequisite and important foundation for the application and development of LBS is good positioning technology, but the existing indoor positioning technology has many shortcomings in positioning accuracy, system cost, user experience, etc., which restrict the development of indoor LBS. Wireless Local Area Networks (WLAN) positioning has the advantages of low positioning system construction cost, support for more user terminals, and convenient use. It has become a hot spot in the research of indoor positioning technology. This paper conducts a more in-depth research on WLAN positioning technology, focusing on the commonly used location fingerprint positioning algorithms, and analyzes the propagation characteristics of wireless signals in the indoor environment from the perspective of positioning. The problems in computing time and other aspects are studied, and the corresponding solutions are given. Through experiment comparison, the effectiveness of the given method is verified.
