Research on Real-Time Data Wireless Communication System Based on LoRa Technology

This paper takes the application of high-precision BeiDou positioning system as a starting point, and uses IoT wireless communication technology to build a dedicated network to meet the demand for real-time data transmission between mobile devices. LoRa technology, which has the characteristics of low power consumption and long distance, is chosen as the wireless communication method, and a wireless communication data transmission system based on FPGA and LoRa technology is proposed. The system comprehensively considers the actual working environment, transmission distance, reliability and other issues, and designs a multi-hop hybrid topology transmission network composed of multi-level devices to realize a long-distance and high-stability transmission link. The experiments show that the system has good signal coverage in the network-deprived areas and can support the centimeter-level positioning of BeiDou satellite data for fixed solving and decoding requirements. The research improves the data transmission volume and communication stability of LoRa network communication system, which reduces the communication cost of the mobile communication network and improves the real-time performance of the overall system at the same time, and the research has the value of engineering practice with a wide range of practical application prospects.
