大型商场wifi覆盖方案首选cable WiFi方案
发布日期：2016/08/17 08:00:00
大型商场WIFI覆盖方案中，要满足各个角落都有wifi均匀覆盖，需要的设备和搭建技术更先进和复杂。一般来说，为了保证较高的wifi覆盖率，为了减少对人体的辐射，为了节省成本又有较好的效果，在构件大型商场wifi覆盖时，会采用cable WiFi方案。
cable WiFi方案是目前wifi覆盖服务商主推的大型商场wifi覆盖方案，包括同创双子等大型的wifi覆盖供应商均采用这种解决方案。
CableWi-Fi系统是一种利用墙体内原有的CATV同轴电缆来传输Wi-Fi信号，低损耗地穿过墙体，实现绿色环保均匀覆盖的目的。它的原理是：把Wi-Fi信号与CATV信号高隔离地混合在一起，然后通过多根CATV同轴电缆传输到各个房间的TV专用面板，通过TV专用面板把两种信号无失真地分离开来，并通过面板附带的Wi-Fi天线发射出来，以达到绿色环保均匀无缝覆盖的效果。由于Wi-Fi信号经过分路器以及同轴电缆的衰减，到达各个房间后，发射出的信号远远低于直接安装无线路由器发射的功率，从而实现了无线局域网绿色环保覆盖的效果;同时，采用这种方案也有效地缓解由于手机或PAD终端相对无线路由器的发射功率弱带来的上下行信号不平衡的问题;也解决了在安装多个路由器情况下，终端用户移动时频繁切换路由器带来性能下降的问题，相对于目前比较流行的插墙式AP来说，CableWi-Fi方案具有AP的频点少，交叉干扰小和绿色环保的优势。
所以说，cable WiFi方案是大型商场wifi覆盖方案的首选。
