Abstract

An enhanced cellular layout for cellular networks having six-sectored cells is disclosed. In one embodiment, the cellular layout is implemented by rotating directional antennas located at each cell site of a triangular cellular layout of a six-sectored CDMA network clockwise or counterclockwise by approximately 10.893° or rotating directional antennas located at each cell site of a parallelogram cellular layout of a six-sectored CDMA network clockwise or counterclockwise by approximately 19.107°.

Claims

AMENDED CLAIMS
[received by the International Bureau on 12 January 1999 (12.01.99); new claims 31-50 added; remaining claims unchanged (3 pages)]
31. A code division multiple access ("CDMA") network comprising a plurality of six-sectored cells each having at least one directional antenna located at a cell site thereof, wherein for each of said six-sectored cells, each said at least one directional antenna thereof is oriented such that a line bisecting a corresponding one of said sectors of said six-sectored cell forms an angle β with a line between said cell site of said six-sectored cell and said cell site of an adjacent one of said six-sectored cells, wherein said angle β is selected from a range of angles consisting of 19.107° ±3°.
32. The CDMA network of claim 31 wherein said cell site comprises at least six directional antennas.
33. A code division multiple access ("CDMA") network comprising a plurality of six-sectored cells each having at least one directional antenna, said CDMA network created by rotating each said directional antenna an amount β with reference to a corresponding antenna oriented for creating a parallelogram CDMA network cellular layout, wherein β is selected from a range of angles consisting of 19.107° ±3°.
34. The CDMA network of claim 33 wherein said rotating is performed in a clockwise direction.

45. The method of claim 41 wherein each said at least one cell comprises six sectors.
46. A method of improving performance of a cellular communication network comprising at least one cell: providing at least six directional antennas at each cell site; orienting each said directional antenna such that a cellular layout of said cellular communication network is a triangular cellular layout; and rotating each said directional antenna at each cell site in a first direction a first predetermined amount; wherein said first predetermined amount is selected from a range of angles consisting of 10.893° ±3°.
47. The method of claim 46 wherein said first direction is clockwise.
48. The method of claim 46 wherein said first direction is counterclockwise.
49. The method of claim 46 wherein said cellular communication network is a code division multiple access ("CDMA") network.
