iNet300 as an industrial wireless network radio is used in coal mines, water conservancy and other fields of wireless data transmission. This paper shows multiple iNet300 network radios in order to compose of point-to-point wireless data transmission link. The problem is solved that blind spots of public network is difficult to transfer geological hazard message to public network. Debris Flow of Everest Bridge is in plateau region where has lower noise, weaker interference, higher bandwidth for the signal environment in the Core Reserve of the Everest. By monitoring geological hazard with iNet300 network radio, it is proved that this device extends the public signal to blind spot in order to monitor the video and integrated data. In conclusion, requirement of design is to be achieved in actual experiment%iNet300作为一款工业级的无线以太网设备,多运用于煤矿,水利等领域的无线数据传输.本文利用多个iNet300网络电台,组成点对点的无线数据传输链路,以延伸公网信号来解决公网盲区地质灾害信息难以传输的问题.珠峰核心保护区的珠峰桥泥石流沟属高原地区,具有低噪声、弱干扰、高带宽的电磁环境,通过应用iNet300网络电台对其地质灾害进行了测试研究,首次证明利用该设备延伸公网信号以实现视频、数据综合业务的远程传输是可行的,达到了预期设计要求.
