摘要： A point-to-point, wireless, millimeter wave trunk line communications link at high data rates in excess of 1 Gbps and at ranges of several miles during normal weather conditions. This link is combined with an Ethernet network to provide high speed digital data communication among a large number of users. In a preferred embodiment a trunk line communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. 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. 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 spectrum. Antennas and rigid support towers 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. In this preferred embodiment the Ethernet network is a Gigabit Ethernet providing data communication among switch banks at 1 gigabits per second and communication among a large number of users at 100 Mbps.

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： A point-to-point, wireless, millimeter wave communications link providing data transmission rates of over 1 billion bits per second (more than 1 Gbps) at ranges of several miles during normal weather conditions. In a preferred embodiment a communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. 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. The transceivers are equipped with antennas providing divergence of less than 10−4 steradians so that an almost unlimited number of transceivers can use the same spectrum. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz. During very bad weather conditions this data link will not provide a 10−10 bit-error rate and 99.999% availability. Therefore, a second transceiver pair operating in the 3 to 30 GHz microwave range acts as a backup to achieve the above bit-error rate and availability requirements, but at a temporarily lower data rate.

摘要： A low cost microwave antenna. Microwaves are radiated from or collected by a thin layer radiating-collecting microwave guide section in which a dielectric slab is sandwiched between a metallic bottom plate and a metallic radiating-collecting cover plate. The cover plate contains a large number of slots spaced to produce outgoing or define incoming microwaves beams having directions determined: (1) by the directions of propagation of microwave radiation within the radiating-collecting microwave section and (2) by the frequency of the radiation. In a collection mode, a microwave lens focuses microwave radiation propagating in the waveguide section at focal locations which are dependent on the direction of propagation of the radiation in the waveguide. Alternatively, in a radiation mode, the lens converts microwave energy broadcast from said focal locations into parallel beams propagating in the radiating-collecting microwave guide section.
