Abstract: The frequency reuse technique that is used to face the insufficiency of bandwidth available for cellular service operators to extend the network capacity. Although, cells use the same channels are physically separated by a reused distance, the problem of interference in the same channel that affect the system performance will be created. In this research, the simulation results are supported to study the impact of increasing carrier frequency for reduce cell radius size and frequency reuse factor on system quality. Where two tier co-channel interfering cells are effective. The up-link (reverse link) of cellular network and the dualslope path loss propagation model are used for analysis network performance. The results are shown that for higher frequencies and smaller cell radius, the two tier of co-channel interference cell become effective comparison to frequencies of 1800 MHz. This leads to a reduce in the quality of the system as well as increasing in reuse factor led to increase in the quality of system but this undesired for capacity.
