| 摘 要： | 在广东省最恶劣的气候是降暴雨，研究降雨对WLAN室外传输的影响很有必要。对于802，11bWLAN的固定无线接入系统，导出在自由空间、晴朗天气和降雨时的接收功率表达式。把晴朗天气的接收功率表达式与降雨时的接收功率表达式进行比较，可以得到降雨衰耗的表达式，进而求得降雨衰减系数。研究得出的降雨衰耗和降雨衰减系数值，不仅对WLAN的固定无线接入，而且对移动通信都具有参考价值。

| Abstract: | Rainstorms are the worst climate in Guangdong. Therefore, the research on rainfall on WLAN outdoor transmission is very essential. As for 802.11b WLAN fixed wireless access system, compared with the received power expression during sunny days and that during rainstorms, the received powerexpression can be obtained in difference weathers. The research result and the rain attenuation coefficient thus obtained provide valuable reference not only in WLAN and immobile wireless accessibility but also in mobile communi- cation. |
