ABSTRACT
This chapter surveys related literature on fractional frequency reuse (FFR) Worldwide Interoperability for Microwave Access (WiMAX) base station technology. It describes the cellular network concept and explains the intercell interference (ICI) phenomenon that occurs in cellular network deployment. The chapter describes the frequency planning and FFR as basic techniques that are used to address the ICI in cellular networks. It introduces the classification of the FFR technique. The chapter highlights the challenges and possible solutions to improve the performance of the FFR technique. WiMAX is a promising technology for accessing the Internet infrastructure and information highway. The cellular network concept overcomes spectral congestion and a reduction in cell capacity, where it enables the base station to reuse part of the available spectrum without a need for significant changes in technology. Base stations can be deployed adjacent to each other in a cellular network to cover a wide area.
