Performance Evaluation of WiMAX Femtocell

Abstract

Worldwide Interoperability for Microwave Access (WIMAX) , is considered today the most interesting opportunity able to provide coverage distance of almost 50 Km and data throughput to 70 MbPs and to complete wired network architecture enquiry a flexible and cheap solution for the last mile. WiMAX is suffers from poor indoor coverage and the high cost of deploying base station. We can solve this problems by using Femtocell , it is very small cell or home access point ( Femto 10ð€¬¿ð€¬µð€¬¹ ) Femtocells provide better in-premise coverage and reduce macro network deployment costs. While operators are benefited by low backhaul cost, and low power, backward compatible and scalable deployment, the end users enjoy better in-premise coverage, low service usage costs, and a better access to new and innovative applications. In this research a study and analysis of WiMAX network is done by using simulation written in MATLAB. In which the used of Femtocell resulted in improvement in the signal to interference ratio by 63% .and throughput increase by 47%. And also bit rate increased by 10% to 25% the increased of bit rate mean increased in spectral efficiency by 40% .and that the value of time delay decreased in Femtocell case applied by 9% .due to the above recorded enhancement in the performance parameters recommendations are made in assaying and Appling Femtocell for WiMAX network that are to be a technology to solve poor indoor coverage problem.
