Research and system design of indoor positioning scheme based on 5G small cell

Abstract： The combination of high-precision indoor positioning technology and small cell communication network can effectively reduce the cost of deployment and operation and maintenance, and provide important solutions for various positioning application scenarios. Firstly, the common positioning technologies were summarized and compared, and the feasibility of different positioning technologies in small cells was further analyzed. Then, an indoor positioning scheme based on small cells was proposed, and its architecture was described in detail. The scheme had the advantages of easy expansion of transmission network, flexible transmission path and open positioning interface. Finally, the application scenarios and positioning processes of the two positioning technologies selected based on this scheme were presented. The results show that the indoor positioning scheme based on small cells can meet the positioning needs of the consumers and a wider range of vertical industries, which has great significance and application prospects.
