在复合形网络拓朴中,使用工作频段为2.4-2.4835GHz的无线扩频通信设备、车载移动通信设备和多协议、多媒体路由器,与公用分组数据通信网紧密集成,构成具有抗干扰、抗截取、抗破密、可移动的有/无线混合城城数据通信网。网络无线主干带宽256kbps,无线支线带宽64kbps,有线主干带宽64kbps,有线支线带宽96kbps,有/无线互为备用,可动态地在有无线链路之间选择最佳链路。支持目前常用的通信协议(如TCP/IP,PPP,帧中继,DDN等)和话音、传真、图象等多媒体通信业务,无线基站位置、数量和天线的精心选择,可有效地覆盖地形地貌复杂的大面积地域。
In the complex network topology, the use of working frequency band of 2.4-2.4835GHz wireless spread spectrum communications equipment, automotive mobile communications equipment and multi-protocol, multimedia routers, and public packet data communications network closely integrated with anti-interference , Anti-interception, anti-breaking dense, removable / wireless hybrid city data communication network. Network wireless backbone bandwidth of 256kbps, wireless branch line bandwidth of 64kbps, wired backbone bandwidth of 64kbps, wired branch line bandwidth of 96kbps, with / wireless mutual backup, can dynamically choose the best link between the wireless link. It supports multimedia communication services such as TCP / IP, PPP, Frame Relay, DDN, etc. and voice, fax, video and other multimedia communication services. The location, number and antenna of the wireless base station are carefully selected to effectively cover the topography Complex large area.
