摘　　要：目前,电视信号已经从传统的模拟转换为数字,越来越多的广播电视频谱资源被释放出来。为了更好地满足通信传输频谱资源,提高频谱的利用效率,为"互联网+"接入服务商和创新应用提供机会,人们通过研究提出了WRAN,该网络在不影响授权用户业务的前提下可以使用广播电视的空闲频谱资源,为广大的偏远地区或广袤的农村提供数据传输功能。WRAN传输的范围高达100 km,能够为农村用户提供数据传输、路由转发功能,包括多个网元节点,比如基站、用户前端设备、服务器、无线路由器等,能够满足农村信息化需求。文章从农村信息化发展的应用需求入手,探讨了WRAN在农村信息化中的组建与设计。At present, television signals have been converted from traditional analog to digital, more and more radio and television spectrum resources are released. In order to better meet the communication and transmission spectrum resources and improve the utilization efficiency of the spectrum, to provide opportunities for ＂internet ＋＂ access to service providers and innovative applications, WRAN is proposed through research. WRAN can use idle spectrum resources of radio and television without affecting the service of authorized users and provide data transmission functions for vast areas in remote areas or vast rural areas. Transmission range of WRAN up to 100 km, can provide rural users with data transmission, routing and forwarding capabilities, including multiple network element nodes, such as base stations, user front-end equipment, servers, wireless routers, etc., to meet the needs of rural informatization. The article starts from the application demand of rural informatization development and discusses the formation and design of WRAN in rural informatization.
