N=4 tri-cellular plan with alternate channel assignment

This paper presents a family of N=4 and N=3 tri-cellular plans for high density, high capacity cellular networks. The N-4 tri-cellular plan is based on dividing the available channels into 12 or multiples of 12 frequency groups, distributed evenly among 4 tri-cells. The N=3 tri-cellular plan is based on dividing the available channels into 9 or multiples of 9 frequency groups, distributed evenly among 3 tri-cells. The tri-cell is based on three identical cells, driven by a single source. Frequency assignment is based on an ODD/EVEN cyclic and alternate distribution of frequency groups which eliminates adjacent channels, ensuring better adjacent channel performance
