摘要： A wireless cellular communication system in which groups of cellular base stations communicate with a central office via a narrow-band millimeter wave trunk line. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of transceivers will be able to simultaneously use the same millimeter wave spectrum. In a preferred embodiment the trunk line communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A large number of base stations are each allocated a few MHz portion of a 900 MHz bandwidth of the millimeter wave trunk line. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. Antennas are described to maintain beam directional stability to less than one-half the half-power beam width. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz and the half power beam width is about 0.36 degrees or less. Thus, in this system the low frequency band width is efficiently utilized over and over again by dividing a territory into small cells and using low power antenna. And a higher frequency bandwidth is efficiently utilized over and over again by using transmitting antennae that are designed to produce very narrow beams directed at receiving antennae. In a preferred embodiment cellular base stations are prepackaged for easy quick installation at convenient locations such as the tops of commercial buildings.

摘要翻译： 一种无线蜂窝通信系统，其中蜂窝基站组经由窄带毫米波干线与中心局通信。 收发器配备有提供足够小的光束发散的天线，以确保数据信道的有效空间和方向分割，使得几乎无限数量的收发器将能够同时使用相同的毫米波频谱。 在优选实施例中，干线通信链路在毫米波段的92至95GHz部分内工作。 大量的基站分配了毫米波干线的900MHz带宽的几MHz部分。 第一收发器以第一带宽发送并在上述频谱范围内以第二带宽接收。 第二收发机以第二带宽发送并以第一带宽进行接收。 描述天线将波束方向稳定性维持在半功率波束宽度的一半以下。 在优选实施例中，第一和第二光谱范围为92.3-93.2GHz和94.1-95.0GHz，半功率波束宽度为约0.36度或更小。 因此，在该系统中，通过将区域划分为小单元并使用低功率天线，可以一次又一次地有效地利用低频带宽。 并且通过使用被设计为产生指向接收天线的非常窄的波束的发射天线，一次又一次地有效地利用了更高的频率带宽。 在一个优选实施例中，蜂窝式基站预先包装，以便在诸如商业建筑物的顶部的便利位置容易地快速安装。
