1. A cell cluster for use with a frequency re-use pattern, wherein the cell cluster comprises:
- seven cells arranged in first and second adjacent columns, wherein the first column includes four adjacent cells and the second column includes three adjacent cells; and
seven frequency groups assigned to the seven cells such that there are no adjacent channels between any of the adjacent cells once each of the frequency groups are assigned to a cell.

Abstract
A cell cluster for use with a frequency re-use pattern is disclosed. The cell cluster comprises seven antenna sites arranged in first and second adjacent columns having four sites associated with the first column and three sites associated with the second column. Frequency groups are assigned to each of the antenna sites such that no adjacent channel interference exist between the antenna sites or between any similarly configured cell clusters associated with the cell cluster.

13. A frequency re-use plan comprising:
-
a plurality of antenna sites less than nine and more than three associated together in a repeating pattern wherein the number of antenna sites is seven arranged in first and second adjacent columns, wherein the first column includes four adjacent sites and the second column includes three adjacent sites; a plurality of frequency groups assigned to the antennas such that no two adjacent cells have adjacent frequency channels between them once each of the frequency groups are assigned. - View Dependent Claims (14, 15, 16, 17)
