Analysis of the technology and development status of indoor positioning

Abstract

RFID technology is an automatic identification technology that can accurately read and write tags through the radio frequency signals emitted by its equipment. At present, this technology has been widely used in various fields. It also has advantages over other positioning technologies in indoor positioning. This article analyzes and compares eight mainstream indoor positioning technologies including RFID technology in terms of accuracy, anti-interference, etc. At the same time, it also analyzes and compares the algorithms applicable to RFID indoor positioning, and focuses on the analysis and use of neural network technology. Combined with RFID technology to achieve positioning algorithms with strong environmental adaptability.
