General
Because of sea reflex and air asymmetry, each antenna configuration shall insure that the circuit transmission index allowance is above 10dB in the case of 25mm/h storm condition, for the purpose of good transmission quality. Each router adopts horizontal and vertical polarization across to reduce the frequency interference.
Therefore the following requirements have to be fulfilled:
Dachan Island Station – Inner Lingding Island station
• Microwave transceiver with 8×E1
• 1+1 hot standby
• Communication range is 12.5 km
• 95% of the route is across the water surface and 5% is across the mountainous region of island
• Circuit transmission index allowance is above 10dB in the case of 25mm/h storm condition
• Altitude of microwave antennas
o Dachan Island radar station 145.0m
o Inner Lingding Island radar station 66.0m

因为海水反射和气流不平均,每个天线装置应该保证通行信号的指标高于10分贝在25毫米/小时的暴风雨的情况下,这个为了良好的通信品质。
每个路由器都采用水平和垂直的交叉方式来减少频率的冲突。
所以下面的要求是必须要实现的:
Dachan Island(地名) 站点 - Inner Lingding Island(地名)站点
• 微波无线的发射器是 8×E1
• 1+1 热准备
• 通信的范围是12.5公里
• 95%的路由器是穿过水面的5%的是穿过岛上山岭
• 保证通行信号的指标高于10分贝在25毫米/小时的暴风雨的情况下
• 微波电线的海拔
o Dachan Island (地名)雷达站 145.0米
o Inner Lingding Island (地名)雷达站 66.0米
概要
由于海水的折射/映象和空中的不对称,看看后面的蛮难的
算了不花太多时间弄了
不好意思啊
呵呵
