1. A method for frequency allocation in a wireless network, comprising the acts of:
- allocating a first frequency at a first power level and a second frequency at a second power level in a first sector of a cell site;
allocating a third frequency at the first power level and the first frequency at the second power level in a second sector of the cell site; and
allocating the second frequency at the first power level and the third frequency at the second power level in a third sector of the cell site, wherein each sector is allocated at most two frequencies.

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.

13. A method for frequency allocation in a wireless network, comprising the acts of:
-
allocating a first pair of frequencies to a first sector of a cell site;
allocating a second pair of frequencies to a second sector of the cell site;
allocating a third pair of frequencies to a third sector of the cell site, wherein each pair of frequencies are allocated at first and second power levels and at least one frequency of the pair of frequencies allocated to the first and second sectors is not allocated to the third sector. - View Dependent Claims (14, 15, 16, 17, 18)
