Patent ID: 7010304

Claim:
A wireless communication system, comprising: a first plurality of antenna sites situated in a coverage area and associated with a first set of antenna axes that are assigned channel frequencies from a first set of channel frequencies; a second plurality of antenna sites situated in the coverage area and associated with a second set of antenna axes that are assigned channel frequencies from a second set of channel frequencies, wherein the channel frequencies of the first set differ from the channel frequencies of the second set, and the second set of antenna axes is rotated with respect to the first set of antenna axes; a third plurality of antenna sites situated in the coverage area and associated with the first set of antenna axes and assigned channel frequencies from a third set of channel frequencies; and a fourth plurality of antenna sites situated in the coverage area, and associated with the second set of antenna axes and assigned channel frequencies from a fourth set of channel frequencies, wherein the channel frequencies of the first, second third and fourth sets are all different; wherein the antenna sites of the first plurality of antenna sites and the second plurality of antenna sites are alternating arranged in a first plurality of rows and antenna sites of the third plurality of antenna sites and the fourth plurality of antenna sites are alternatingly arranged in a second plurality of rows, and the rows of the first plurality and second plurality of rows are alternatingly arranged so as to substantially occupy the coverage area.
