Lte, Lte-Advanced and Wimax

Towards Imt-Advanced Networks

• Gebundenes Buch

Produktbeschreibung

This book provides a concise introduction to WiMAX and LTE, covering both interface and networking considerations. While many books examine LTE or WiMAX, few compare the two technologies. While Parts I and II introduce and examine WiMAX and LTE respectively, Part III of this book offers a multi-faceted comparison, carefully analyzing and distinguishing the characteristics of each technology and spanning both technical and economic merits. As well as offering a comparison between the two technologies, this book provides a comprehensive description of each technology and its services at the practical and research level.

A concise introduction to IMT-Advanced Systems, including LTE-Advanced and WiMAX

There exists a strong demand for fully extending emerging Internet services, including collaborative applications and social networking, to the mobile and wireless domain. Delivering such services can be possible only through realizing broadband in the wireless. Two candidate technologies are currently competing in fulfilling the requirements for wireless broadband networks, WiMAX and LTE. At the moment, LTE and its future evolution LTE-Advanced are already gaining ground in terms of vendor and operator support. Whilst both technologies share certain attributes (utilizing Orthogonal Frequency Division Multiple Access (OFDMA) in downlink, accommodating smart antennas and full support for IP-switching, for example), they differ in others (including uplink technology, scheduling, frame structure and mobility support). Beyond technological merits, factors such as deployment readiness, ecosystem maturity and migration feasibility come to light when comparing the aptitude of the two technologies.

LTE, LTE-Advanced and WiMAX: Towards IMT-Advanced Networks provides a concise, no-nonsense introduction to the two technologies, covering both interface and networking considerations. More critically, the book gives a multi-faceted comparison, carefully analyzing and distinguishing the characteristics of each technology and spanning both technical and economic merits. A "big picture" understanding of the market strategies and forecasts is also offered.
Discusses and critically evaluates LTE, LTE-Advanced and WiMAX (Legacy and Advanced)
Gives an overview of the principles and advances of each enabling technology
Offers a feature-by-feature comparison between the candidate technologies
Includes information which appeals to both industry practitioners and academics
Provides an up-to-date report on market and industry status

Autorenporträt

Najah Abu Ali works extensively on broadband wireless network architectures, design, QoS provisioning and performance, and has published and lectured in the area of analytical and measurement based network performance management, in addition to QoS and resource management in both single and multihop wireless networks. She is currently an Associate Professor in the Computer Networks Engineering Track at the College of Information Technology in the United Arab Emirates University (Al-Ain, UAE). Her previous posts include a postdoctoral fellow at the Telecommunications Research Lab at Queen's, and an instructor and head of the engineering department at Queen Noor College. She received her B.S. and M.S. degrees in Electrical Engineering in 1989 and 1995 respectively from University of Jordan, Amman, Jordan and her PhD degree in 2006 in Computer Networks in Electrical Engineering department at Queen's University, Kingston, Canada. Abd-Elhamid M. Tah is a research associate at the Telecommunications Research Lab of the School of Computing at Queen's University, Kingston, Ontario. He received the B.Sc. (honors) and the M.Sc. from Kuwait University in 1999 and 2002, and the Ph.D. from Queen's University in 2007. Dr. Taha has worked extensively in the area of broadband wireless networks, especially in the contexts of radio resource management, mixed-technology access networks and extended wireless infrastructure. He has also lectured on emerging broadband technologies (LTE, LTE-Advanced and WiMax) in key IEEE venues such as Globecom and VTC. Hossam S. Hassanei is with the School of Computing at Queen's University working in the areas of broadband, wireless and variable topology networks architecture, protocols, control and performance evaluation. Dr. Hassanein obtained his PhD in Computing Science from the University of Alberta in 1990. He is the founder and director of the Telecommunication Research (TR) Lab (http: //www.cs.queensu.ca/ trl) in the School of Computing at Queen's. Dr. Hassanein has more than 350 publications in reputable journals, conferences and workshops in the areas of computer networks and performance evaluation. He has delivered several invited talks and tutorials at key international venues, including Unconventional Computing 2007, IEEE ICC 2008, IEEE CCNC 2009, IEEE GCC 2009, IEEE GIIS 2009, ASM MSWIM 2009 and IEEE Globecom 2009. Serving on the editorial board of a number of International Journals, Dr. Hassanein is also a senior member of the IEEE and is currently chair of the IEEE Communication Society Technical Committee on Ad hoc and Sensor Networks (TC AHSN). Dr. Hassanein is an IEEE Communications Society Distinguished Lecturer.
