Visions of 4G

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 the limitations of third generation (3G) systems are followed by a vision of 4G for 2010 based on five elements: fully converged services, ubiquitous mobile access, diverse user devices, autonomous networks and software dependency. This vision is developed in more detail from a technology viewpoint into the key areas of networks and services, software systems and wireless access.

4G Wireless Technology

ABSTRACT

As the virtual centre of excellence in mobile and personal communications (Mobile VCE) moves into its second core research program it has been decided to set up a fourth generation (4G) visions group aimed at harmonizing the research work across the work areas and amongst the numerous researchers working on the program. With the major wireless service providers planning to start deployment of 4G wireless networks by mid 2010, research and industry communities are racing against time to find solutions for some of the prominent still open issues in 4G networks. The growing interest in 4G networks is driven by the set of new services will be made available for the first time such as accessing the Internet anytime from anywhere, global roaming, and wider support for multimedia applications.

This paper is provides technological features of an existing 4G communication technology and its architecture to integrate the social networking process. In this paper describe the Opportunities, key challenges and point to some proposed solutions.
