Handover Performance Analysis on Femtocell Technology In Collaboration With Wimax

Abstract

Femtocell is a technology that uses micro BTS low power levels, using frequencies on wireless networks, and backhaul networks connected to the Internet. Femtocell used to expand the coverage and increase capacity and can be installed in homes and office buildings. Capacity at each femtocell base station is around 4-8 users, with a range of 30-100 meters. The most significant advantage of using a femtocell is to improve the quality of the indoor signal. This study discusses how users speed and distance between femtocell affect handover performance in WiMAX Femtocell. The performance here is calculated by the throughput parameters, data dropped, and HO delay. The users move from one femtocell to another femtocell, and from one femtocell to macrocells, so we can see user performance when handover. In the simulation results can be seen user’s handover performance on the network with the femtocell. Without femtocell, the results are that user performance becomes much better with femtocell installed on the network. It also can be seen the influence of user speed and the distance between femtocell user to HO performance. User speed does not affect user handover performance. However, the distance between cell affect user performance, the smaller the distance between femtocell, the greater possibilities of interference, thus affecting user handover performance.
