近年来互联网的高速发展,使网络技术在人们日常生活当中所起到的作用愈发重要。而长期以来,广电宽带网络的发展劣势非常明显。随着广电模拟电视完成数字化改造,700MHz频段逐步释放闲置。700MHz因处于低频段,信号覆盖范围广、穿透性强,较适宜应用于大范围网络覆盖,同时组网成本也相对较低。广电应充分利用这一频谱资源优势,构建双向无线网络,实现广电业务的转型升级。
In recent years, the rapid development of the Internet has made network technology more and more important in people’s daily life. For a long time, radio and television broadband network development disadvantage is very obvious. With the completion of digital radio and television analog transformation, 700MHz band gradually release idle. 700MHz due to the low frequency band, wide signal coverage, strong penetration, more suitable for a wide range of network coverage, while networking costs are relatively low. Radio and television should make full use of the advantages of this spectrum resource to build a bidirectional wireless network and realize the transformation and upgrading of radio and television services.
