Abstract
Due to the insufficiency of available bandwidth and the continuously growing demand for cellular communication services, there are many cells using same frequency band. All the cell using the same channel are physically located apart by at least reused distance, even though the power level is controlled carefully so that such "co-channels" do not create a problem for each other, there is still some degree of interference due to non-zero signal strength of such cells .This paper simulate the co-channel interference ratio (CCIR) for mobile station at the various distance from BS and shows, as the path loss propagation increases, the value of CCIR increases exponentially and achieved a fabulous result and also simulate, for the same value of path loss propagation & varying distance results shows that CCIR decreases linearly. In this paper, two tier model is used for simulating the result. Simulation is done for 1-Tier, although there are negligible interference between focused cell and 2-Tier of CCIR cells over same frequency band.

1. Introduction
In current scenario there are tremendous increases in the demand of cellular phone but insufficiency of available frequency bands have forced to reuse the same frequency channel for the different BS; it introduces the concept of reuse distance for reducing the co-channel interference. If we discuss the strategy of 2-Tier system in mobile system then we need to know that the CCIR is negligible but still non- zero. The system working scenario will be discussed later. In this paper results confined that what will be the CCIR exactly for the MS at various distances for the...
