近几年国际上发展了一种面向用户的数字微波通信系统,叫一点对多点(PMP)微波通信系统。它采用与数字卫星通信时分多址方式类似的原理,能较灵活经济地组织小容量多点通信网络。这种系统特别适用于农村、矿区、边远地区、沿海小岛群及海上油井群等场合使用。也可用这种原理构成城市地区的数据传输网及电视会议网。
In recent years, the international community has developed a user-oriented digital microwave communication system called Point-to-multipoint (PMP) microwave communication system. It adopts the principle similar to that of digital satellite communication time division multiple access and can organize small capacity multipoint communication network more flexibly and economically. This system is particularly suitable for use in rural areas, mining areas, remote areas, coastal islands and offshore oil wells and other occasions. This principle can also be used to construct data transmission networks and video conferencing networks in urban areas.
