4G Wireless Systems

Abstract :

The ever-increasing growth of user demand, the limitations of the third generation of wireless mobile communication systems and the emergence of new mobile broadband technologies on the market have brought researchers and industries to a thorough reflection on the fourth generation. Many prophetic visions have appeared in the literature presenting 4G as the ultimate boundary of wireless mobile communication without any limit to its potential, but in practical terms not giving any design rules and thus any ....etc

4G Activities in Korea



INTRODUCTION

korea is one of the world's most concentrated markets for
high-speed Internet connections. There are also about
36.6 million mobile phones users, or 75 percent of the
population. Broadband service providers have recently been
hit by slow growth, saturation in the market and weak
consumption caused by an economic downturn that has put
the emphasis on the need for new services. We hope the
WiBro service ....etc

ABSTRACT

As the virtual centre of excellence in mobile and personal communications (Mobile VCE) moves into its second core research programme it has been decided to set up a fourth generation (4G) visions group aimed at harmonising the research work across the work areas and amongst the numerous researchers working on the programme. This paper outlines the initial work of the group and provides a start to what will become an evolving vision of 4G. A short history of previous generations of mobile communications systems and a discussion of t ....etc
