description: With the onset of the information age, people's demand for information is growing. With the advent of big data and cloud computing, location information has become especially important. Location-based services have changed our lives. With the rapid development of wireless networking and smartphone technology, mobile terminals are used in a wide variety of fields. To meet the needs of indoor positioning, this article analyzes the positioning of Wi-Fi wireless LAN signals. The main research work is as follows: 1. Briefly describe the importance of positioning in the current situation. Summarizes the current types of indoor wireless positioning, briefly analyzes the characteristics of various wireless positioning systems, and studies the factors that influence positioning. 2. This paper discusses online matching algorithms, including Bayesian and Nearest Neighbor. 3. This paper discusses indoor positioning techniques and indoor positioning algorithms. The internal positioning method includes the TOA scoring method, the TDOA scoring method, the AOA scoring method, and the RSS scoring method. The internal positioning algorithm includes Nearest Neighbor, K Nearest Neighbor, Weighted Neighbor Algorithm, Kernel Function Method, BP Neural Network, Support Vector Machine Algorithm.
