摘要
为解决城市环境下应急无线通信网络的快速机动部署,提出并实现了一种可用于局域、城域等多种维度的无线自组网络整体方案。该网络利用大增益无线网桥、室内小型无线网状网络路由器及无线接入点等设备,实现了一种长短距离结合、室内外覆盖结合的无线自组网络。该网络在实际建设过程中具有部署快速、成本低廉等优势。介绍了该方案的实现方式,并对网络进行了实际测试。测试结果表明,在传输距离1 km且无遮挡情况下,网络带宽最高可达到180 Mbps以上,可用于无线城域网及局域网的实际部署。
In order to meet the requirement of rapid and flexible deployment of wireless emergency communication networks in urban environment,a multi-scale wireless ad-hoc network scheme is proposed which can be used in wireless LAN and MAN. Devices such as high gain wireless network bridges and indoor wireless mesh routers are used to realize a wireless ad-hoc network which combines long and short distance as well as indoor and outdoor coverage scenarios.It has advantages such as rapid deployment and low cost.The whole scheme and the implementation method are introduced and tested.The result shows that the network bandwidth can reach above 180 Mbps when the transmission distance is about 1 kilometer without any shelter,and the network can be used in practical applications.
