  • Patent number: 6748218
    Abstract: Wireless communication methods and systems using multiple sectored cells. In one example, each cell of a cellular coverage area is divided into a number of sectors. A number of different half duplex or full duplex channels are used in each cell to communicate between a base station and a number of subscriber stations located in the cell. At least some of the channels may be reused in other cells of the coverage area. Additionally, some channels may be reused both amongst sectors of a given cell and in other cells of the coverage area. The sectored cells are arranged with respect to one other such that interference amongst similarly oriented sectors of different cells using one or more same channels is reduced.

    Abstract: Wireless communication methods and systems using multiple sectored cells. In one example, each cell of a cellular coverage area is divided into a number of sectors. A number of different half duplex or full duplex channels are used in each cell to communicate between a base station and a number of subscriber stations located in the cell. A number of different cell configurations may be derived based on different channel sequences amongst cells using same channels, different rotations (azimuth orientations) of the cells with respect to one another, and/or different channel types used amongst cells. Based on the different cell configurations, a variety of core sectored cell groups may be formed and implemented in extended formations.

  • Patent number: 6046701
    Abstract: A sectored antenna system has one or more dielectric lenses, each having a surface and two or more antenna feed devices tilted non-parallel to the lens surface and preferably angled in a V pattern. At least one of the feed devices radiate signals into said lens that emerge as separate directional beams, or the lenses receive incoming signals from different directions and focus them onto different antenna feed devices. The feed devices of the sectored antenna system have a dielectric constant of between about 5 and 15 and preferable about 10 and further has a mounting collar to mount the antenna feed devices about the lens to adjust for elevation, azimuth, radial and rotational orientation.
