Problems solved by technology

The positioning range of Beacon is divided into three levels: Immediate, Near, and Far. Different levels can have different reference signal settings. Since the transmission power of Bluetooth devices is smaller than other mainstream indoor positioning technologies, the overall positioning accuracy of Bluetooth is The current mainstream indoor positioning technology is the highest (<10m), but the deployment density is also the highest, and the positioning accuracy is also proportional to the spacing and density of Beacon equipment deployment.
[0004] At present, under the existing deployment density of station spacing based on LTE technology, the accuracy is difficult to meet the requirements of indoor positioning (<6m). The positioning accuracy can be improved by adding indoor LTE sites, but this will increase the cost of deploying base stations. On the other hand, adding new equipment to indoor scenes with established LTE coverage will introduce problems such as reconfiguration, transmission, and wiring. Therefore, it is a key issue for indoor positioning to adopt a low-cost and low-complexity solution to improve LTE indoor positioning accuracy.
[0005] In addition, while providing high-precision positioning through high-density deployment of Bluetooth Beacon devices indoors, it will also bring deployment and management problems, and the Bluetooth positioning service requires the terminal to turn on the Bluetooth switch, and it needs to be available when the terminal is not in power-saving mode. Therefore, the samples using Bluetooth positioning must be limited, so the use of Bluetooth networks alone to provide indoor positioning also has certain limitations.
