MMDS在海岛地区有线电视联网中的应用和实践

Application of MMDS in Insular Zone CATV Network

介绍 2 .5GHzMMDS微波传输系统在地理环境和气候条件特殊的海岛地区有线电视联网的应用 ;探讨了大气衰落和雨、雾以及海上镜面反射对微波传输的影响。

This paper presents application of MMDS(2.5GHz) microwave transmission system in CATV Network in zone district where the geographic environment and climate are special, and approaches how to affect microwave transmission by atmospheric collapse, rain, fog and mirror reflection on the sea-level. It also accounts for how to select antenna and feed line system, and proceedings in the concrete execution.
