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 10 )
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.
