Abstract

This paper focuses on the analysis and performance evaluation of worldwide interoperability for Microwave Access using
MATLAB based approach. In the 5th generation of wireless mobile telecommunication network, the request for an elevated data
rate with access to portable customers is overwhelming. Mobile worldwide interoperability for Microwave Access (WiMAX)
becomes a favorable alternative that is intelligently developed than Wireless Fidelity (Wi-Fi). This technology makes use of
Orthogonal Frequency Division Multiple Access (OFDMA) for its two-way communications to enhance the system performance
in fading environments. Furthermore, in this paper, whenever the user stays away from the base station with a particular SNR, a
poor quality of signal can be achieved due to degradation. Also, whenever the user stays closer to the base station for the same
SNR, a good quality of signal can be maintained. The results obtained shows that OFDMA has the most increased capacity and
best performance according to the values of BER and SNR.
