    • Network, method, base station and antenna are disclosed to establish three-dimension cellular signal coverage, especially coverage in upper floors of high-rise buildings in city, for a cellular telecommunication system. To expand base station coverage to space above ground, up-tilt antenna and down-tilt antenna are coupled together to share base station transceivers, so as to share cellular frequency spectrum, expand coverage and meanwhile avoid interferences. The down-tilt antenna covers ground; the up-tilt antenna covers space above ground, especially the upper floors of high-rise buildings in its cell. A multibeam multi-tilt base station antenna is invented to replace a down-tilt antenna and an up-tilt antenna to provide three-dimension coverage with single antenna. It has one beam pointing downward to cover ground and one beam pointing upward to cover space above ground in a base station.
    • 公开了网络,方法,基站和天线,以建立三维蜂窝信号覆盖,特别是在城市高层建筑物的上层覆盖,用于蜂窝电信系统。 为了将基站覆盖扩展到地面以上,将上行天线和下行天线耦合在一起共享基站收发信机,共享蜂窝频谱,扩大覆盖范围,同时避免干扰。 倾斜天线覆盖地面; 向上倾斜的天线覆盖地面以上的空间,特别是其单元中高层建筑物的上层。 发明了一种多波束多倾角基站天线来代替下倾天线和上倾天线,以提供单天线的三维覆盖。 它有一个光束向下指向地面,一个光束指向上方,以覆盖基站的地面以上的空间。
