Abstract:
1. A method of arranging a wireless network coverage area, comprising: defining at least a first set of channel frequencies and a second set of channel frequencies by allocating distinct channel frequencies selected from an available bandwidth to the first set and the second set of channel frequencies; associating the first set and the second set of channel frequencies with a first set and a second set of antenna axes directions, respectively, such that each channel frequency is associated with a single antenna axes direction wherein each of the sets of antenna axes directions includes three antenna axes directions angularly spaced by about 120 degrees and wherein the first set of antenna axes directions is rotated by about 60 degrees with respect to the second set of antenna axes directions; and assigning the first set of channel frequencies and the associated first set of antenna axes directions, and the second set of channel frequencies and the associated second set of antenna axes directions to respective pluralities of antennas situated in the wireless coverage area, wherein the wireless coverage area comprises at least two rows of cells with each cell having the assigned first set of channel frequencies and the associated first set of antenna axes directions being adjacent to at least one cell having the assigned second set of frequencies and the associated second set of antenna axis directions.
