Abstract

In order to cope with the increase in demand for stable and high data rates among mobile users, femtocell or called as Home Evolve Node B (HeNB) has been developed to improve indoor capacity and coverage. Femtocell is a small base station aims for indoor usage such as at home or enterprise. The femtocell transmits a cellular signal that is received by mobile users then backhauled through the user’s wired broadband connection. It is very user deployed so it reduces operations cost for mobile operators, and at the same time provide a high user experiences to users. However, femtocell deployments caused interference between femtocells itself and also to the existing macrocells. This paper analyzed the interference management which are combining of Fractional Frequency Reuse (FFR) and Dynamic Power Control (DPC) methods by looking on the Signal to Interference plus Noise Ratio (SINR) performance based on the proposed fraction of cell radius (rth), fraction of system bandwidth (ß) and path loss compensation factor (a) value in our previous papers. The proposed rth, ß and a are then used in the simulation model in order to analyzed the SINR performance between the proposed method and the conventional method. The simulation results showed that the proposed method gives the higher values of SINR and show that there is a significant reducing of interference occurrence compared to the conventional method.
