A communication base station, also known as a wireless base station, refers to a low-power wireless antenna that communicates with a user's mobile phone. Depending on its service range and number of users, the transmission power ranges from a few watts to hundreds of watts. In general, base station antennas are installed on buildings or transmission towers 15 to 50 meters above the ground. With the development of society and the improvement of people's lives, the increasing popularity of the Internet of Things, as well as the further enhancement of mobile terminal functions, the demand for location-based services is becoming increasingly strong, and the application of location-based services (LBS) is also widely popular. Mobile operators and software developers are researching and releasing attractive LBS products and services, and in modern logistics, transportation Emergency search and rescue have been widely applied in various fields of the national economy, becoming a universal social basic service. This article classifies and studies wireless positioning technology from the perspective of mobile communication base stations, and summarizes and prospects typical products and applications based on location services, providing useful reference for future research on the Internet of Things based on wireless base station positioning P>
