The approaching 4G (fourth generation) mobile commu- nication systems are projected to solve still-remaining problems of 3G (third generation) systems and to provide a wide variety of new services, from high-quality voice to high-definition video to high-data-rate wireless channels. The term 4G is used broadly to include several types of broadband wireless access communication systems, not only cellular telephone systems. One of the terms used to describe 4G is MAGIC—Mobile multimedia, Anytime any- where, Global mobility support, Integrated wireless solu- tion, and Customized personal service. As a promise for the future, 4G systems, that is, cellular broadband wire- less access systems, have been attracting much interest in the mobile communication arena. The 4G systems not only will support the next generation of mobile service, but also will support the fixed wireless networks.
This paper presents an overall vision of the 4G fea- tures, framework, and integration of mobile communica- tion. The features of 4G systems might be summarized with one word—integration. The 4G systems are about seamlessly integrating terminals, networks, and applica- tions to satisfy increasing user demands.
The continuous expansion of mobile communication and wireless networks shows evidence of exceptional growth in the areas of mobile subscriber, wireless net- work access, mobile services, and applications. An esti- mate of 1 billion users by the end of 2003 justifies the study and research for 4G systems.
