★ Frequency Reuse is one of the techniques for improving capacity and spectral efficiency

★ Commercial wireless systems are based on Frequency Reuse, that involves the partitioning of an RF radiation area into cell segments.

★ A frequency that is far enough away from the frequency in the bordering segment is used by one segment of the cell.

★ Similar frequency is used at least two cells apart from each other.

★ This practice enables various cellular providers to have several customers for a given site license.
