Impact of femtocell on the performance of WiMAX

Abstract

Femtocells are low power base stations operating in licensed spectrum with the intent to improve coverage and performance of multimedia and broadband services. The femtocells provide a solution to improve indoor coverage of cellular mobile devices in the areas where the coverage is weak and intermittent while using macrocells. The use of data hungry devices such as, tablets, smartphones and other wireless devices are increasing rapidly with time and is a driving force for innovative ways in wireless communication to provide fast access to the internet, more capacity and higher quality of service. Femtocells can provide a useful way for mobile operators to offer a better user experience and deliver indoors broadband services consistently and reliably for a comparable context of application, distances, and obstacles. The proposed work will analyze the efficiency of femtocells in terms of its convergence along with WiMAX wireless technologies. The study will show how the coverage is improved by femtocells and how the total network capacity gains can be up to many times as compared to the current macro layer networks. This analysis will be based on more detailed performance parameters such as throughput, packet loss, packet end to end delay, download and upload response times for multimedia traffic. The femto access points (FAPs) will enhance data rates via improving link quality, shorter communication distance and less penetration loss resulting into increased capacity of the entire system.
