描述

两点之间(如总部和分支机构、网络中心和小区等)建立通信连接。从客户的需求和实际勘查的状况来看传输方式，并进行适合的无线网桥设置，有以下几种传输方式：

(1)AB两点之间可视；没有障碍物阻挡；无电磁干扰，或干扰小；AB两点之间距离符合网桥设备通讯距离的要求。

可采用点对点方式直接传输：A大楼放置一台无线网桥，顶部放置一面定向天线；B大楼同样放置一台无网桥，顶部放置一面定向天线。两地的无线网桥分别通过馈线与本地天线连接后，两点的无线通讯可迅速搭建起来。无线网桥分别通过超五类双绞线连接各地的网络交换机。这样两处的网络即可连为一体。

产品广泛应用于：电力、石油、矿井提升、港口、供热、燃气、供水、污水处理、冶金、造纸、纺织、化工、水利等现代化工业领域！
