Design and Implementation of a Mobile Device Transmission Mechanism with LoRa

Abstract

Close-range wireless communication technologies such as Zigbee BLE and NFC have matured but the transmission distance of these technologies is about 10 meters so there are many restrictions when the long-distance transmission is required LoRa (Long Range) combines long-range low-power consumption etc allowing users to have an additional choice for long-distance communication over IOT devices It is also suitable for applications in terms of usage due to its long-range characteristics Therefore this paper will explore the effects of various parameter settings on the long-distance wireless transmission across the sea on its receiving rate and error rate transmit the GPS grease value corrected by RTK obtain the parameter results between the various distances and analyze the transmission of different parameters at different intervals The data select the most power-saving and high packet correct rate at each range and realizes a mobile device equipped with LoRa The device can adjust the most suitable parameters according to different distances transmission success rates Achieve the most efficient transmission method
