On the application of LoRa LPWAN technology in Sailing Monitoring System

Sailing Monitoring System operating in the sea area has the basic transmission requirement of low power and long range. LoRa Low Power Wide Area Network (LPWAN) technology can be seen as an alternative solution to address this problem. This study focuses on transmission performance of LoRa technology and attempts to apply LoRa technology to Sailing Monitoring System. Experiments of LoRa technology parameters' (e.g. spread factor and bandwidth) influences on data transmission time and coverage were set up. Then, the optimal parameters of LoRa technology are used in Sailing Monitoring System, and the evaluation of system's performances is given. The measurements were conducted in Brazil Olympics sailing venue for two cases, and system's performance of coverage and packet loss rate in sea area are analyzed. It shows that the system based on LoRa technology can achieve the intended purpose of system design and meet the basic requirement of system applications. In the concluding section, measurement results are summarized and the future research directions are presented.
