To provide flawless and high speed services among highly increasing users with limited bandwidth has become today's problem.To overcome this problem, a different but efficient frequency allocation system is needed.Instead of conventional Frequency Reuse system, the Fractional Frequency Reuse (FFR) could be a better solution for all voice channels.In this work, a new scheme namely Proposed Fractional Frequency (PFFR) has been proposed as well as a new system model that implements PFFR has been suggested.The main purpose of this analysis is to make a comparative analysis between the performances of PFFR and conventional or Traditional Frequency Reuse Factor (TFRF).Here, the performances of carrier to interference ratio, traffic and trunking efficiency are measured and analyzed to find improvements on frequency planning.In this proposed system module, the whole cellular area has been covered by using both Omni and Sectoring antennas to ensure the full coverage of not only in smaller cells but also at the cell edges of larger cells with the intelligent utilization of PFFR.This analysis is simulated by using a simulation tool MATLAB r2010a.The result of this work has shown a great improvement on CCI with PFFR as compared with the conventional frequency reuse.In this paper it has been shown that the intelligent implementation of PFFR can offer distinct advantages in terms of improved CCI, GoS (Grade of Service), and traffic and trunking efficiency to cellular mobile networks.
