In addition, positioning technologies such as Wi-Fi-based feature matching positioning are also in the process of research, and it is believed that they will be popularized in the lives of the public in the near future.

The realization of the above-mentioned types of positioning systems generally requires the following steps. First, analyze the structure of the indoor building and select the training points that need to collect data. Then let the mobile terminal enter the positioning environment, and stay at those designated training points that need to measure the signal strength, and the positioning tag measures and saves the signal strength sent by the mobile terminal. Finally, analyze the signal strength collected from the above multiple measurements, calculate the signal strength distribution in the positioning environment, and complete the construction of the positioning environment. After the user enters the built positioning environment with a mobile terminal, according to the strength of its transmitted signal, and referring to the data collected and calculated when setting up the environment, its specific position can be calculated.

Although the positioning of this type of system is relatively accurate, it can be seen that the construction of the positioning environment is very complicated. In addition, it also has disadvantages such as a large amount of data required for positioning, a large space occupation, and a complicated implementation algorithm.
