4G Wireless Technology



With the emerging innovations in wireless communication networks, it is anticipated that fourth generation (4G) mobile systems will be launched within a decade or before. 4G mobile systems focus on seamlessly integrating the existing wireless technologies including WCDMA, HSUPA/HSDPA, 1xEVDO, Wireless LANs, and Bluetooth. 4G systems aspire to support comprehensive and personalized services, providing stable system performance and quality services. However, with everchanging specifications and standards, developing a prototype that provides the 4G system\'s capabilities requires a flexible process. Besides, migrating current systems to 4G present\'s enormous challenges. This paper is an attempt to give a brief description of fundamentals like dangers, challenges of 4G and about the visions that the network operators and service providers see for the evolution of 4G mobile systems. The paper endeavors to make an evaluation on development, transition and roadmap for fourth generation mobile communication system with a perspective of wireless convergence domain. Finally, a brief discussion on future research issues in 4G is presented.
