Problems solved by technology

Among the above positioning solutions, Wi-Fi positioning is more common due to the popularity of mobile terminals such as mobile phones. It has the advantages of low hardware cost and convenient base station deployment, but the hardware power consumption of Wi-Fi positioning is high and the positioning accuracy is poor; The characteristics of the positioning signal itself determine that it is extremely susceptible to interference from other signals, the positioning accuracy is poor, and there are problems such as reflection and refraction in the non-line-of-sight (NLOS) environment, which makes the positioning environment strict and the positioning range is also small
