| 摘 要： | 无线接入是有线接入的重要补充和应急备份,尤其对于通信比较落后的乡村或人口分散地区有着重要的意义,可以克服地形复杂、地广人稀、铺设有线电缆的方式不经济的缺点.以解决偏远地区分散用户的网络需求为目标,根据安徽地区的实际需求及合作企业提出的实际问题,以淮北地区"村村通"工程建设为例,与淮北市广电传输中心暨安广网络公司淮北分公司合作,基于当地数字电视微波频段进行宽带无线接入技术的研究.研究设计了基于MMDS(microwave multipoint distribution systems)微波电视网络的宽带无线接入系统,以实现数字电视微波的双向传输拓展,提高频谱资源的利用率,实现绿色通信.
