Next generation wireless communication systems require a higher broadband performance to support highly realistic rich content and still be capable of seamlessly supporting integrated services using a variety of different network access systems. This paper reviews the current trends in broadband wireless communication systems, including cellular, wireless LAN, and fixed wireless access (FWA) systems. Furthermore, we describe the recent activities in the development of software defined radios (SDRs) that are essential for realizing the systems beyond 3G, with a particular focus on processor and security issues.
