摘　　要：使用Wi-Fi无线技术进行室外数据远距离传输时,设备在室外通信中不可避免地会遇到降雨影响无线通信距离的问题。通过量化分析雨天对Wi-Fi无线信号传输造成的影响,说明了当前Wi-Fi无线信号远距离传输方案应对雨天时的局限性,并提出有效的应对措施,以保证Wi-Fi设备间的正常通信。When Wi-Fi wireless technology is used for outdoor long-distance data transmission, equipment in outdoor communication is inevitably affected by rain, leading to wireless communication distance. The impacts of rain on Wi-Fi wireless signal transmission were quantitatively analyzed and the limitation of existing Wi-Fi wireless signal long-distance transmission schemes to deal with rain was illustrated. In addition, correspondingly effective countermeasures were presented to guarantee the normal communication between Wi-Fi equipment.
