Abstract
A frequency reuse scheme that provides high spectral efficiency and reduced interference in areas where cell sites overlap is provided. Three frequencies are allocated per cell site, with each sector employing two frequencies, one frequency being transmitted at a higher power and the second frequency being transmitted at a lower power. The higher power frequency in one sector differs from the higher power frequency employed in the other two sectors, and the lower power frequency used in one sector differs from the lower power frequency used in the other two sectors.
