Underlay-Overlay of LTE Cells Capacity with Fractional Frequency Reuse

Mobile phones need connected to high speed network for multimedia service, LTE network can be offered. Micro/macro cell technique with FFR (Fraction Frequency Reuse) used to increase the capacity of cellular mobile system. Performance of system depend on co-channel interference from neighboring cells. Cell sector used for reducing the co-channel interference from neighboring cells and improve the system performance. For increase more system capacity, this paper proposes 3 models of overlay-underlay cell for LTE system. Simulation results show the best model for LTE cell layout.
