摘要

本文针对低功率广域无线电在水产养殖中的应用，阐述了亚千兆频段无线电波的海上传播特性。该方案的一个特点是高灵敏度低功耗通信系统(RSSI:接收信号强度指标-典型142 dBm，发射机功率在920 MHz时为20 mW)，距离为22公里。此外，还确定了岛大小(传播线上的宽度)对衍射现象的影响很大，可以用多刀口模型来表示。

Analysis of Sub-Giga Band Propagation for Maritime Low Power Wide Area Application

In this paper, we clarify the characteristics of sub-Giga band radio wave propagation at sea for the application of LPWA (Low Power Wide Area) radio in aquaculture. A particular feature of this scenario is high-sensitivity low power communication system (RSSI: received signal strength indicator-142 dBm typical, transmitter power 20 mW at 920 MHz) over a 22 km distance. Additionally, it is determined that the island size (width on a propagation line) has a great influence on the diffraction phenomenon, which can be expressed by a multiple knife-edge model.
