通常计算机组网的传输媒介主要依靠铜缆或光纤构成有线局域网 ,但有线网络要受到布线的限制 ,布线、改线工程量大 ,线路容易受损 ;网络中各节点不可移动 ,特别是要把相距较远的局域网或节点联结起来时 ,敷设专用通信线将受到布线施工的限制 (费用高、耗时长、施工难度大等 ) ,对迅速扩大网络的需求形成严重的阻塞。无线组网技术就是为解决有线网络的以上问题而出现的。本文介绍福建电视台在市区内几个子网采用无线网络技术组网的尝试
Usually, the transmission media of computer networking relies mainly on copper cables or optical fibers to form wired LANs. However, the wired networks are limited by cabling. Large quantities of cabling and rewiring are required and the lines are easily damaged. The nodes in the network can not be moved. In particular, When the remote LANs or nodes are connected, laying dedicated communication lines will be limited by the wiring construction (high cost, long time consuming, difficult construction, etc.), causing a serious congestion to the demand of rapidly expanding the network. Wireless networking technology is to solve the above problems of the wired network. This article describes Fujian TV station in the urban area several subnets using wireless network technology network attempt
