WiMAX Evolution

Dr Marcos Katz, VTT, Finland Dr Katz received his PhD from University of Oulu, Finland in 2002. He has 20 years of experience in the field of wireless communications (industry, academia and, research institutions). He has edited 2 books and published widely in journals and conferences. He is currently a Technical Manager of EU FP6 Integrated Project dealing with new WiMAX scenarios, technical solutions and test-beds. He is developing multiantenna solutions for new WiMAX scenarios (environmental monitoring), and is also involved in exploring novel WiMAX architectures exploiting cooperation. Professor Frank Fitzek, Aalborg University, Denmark Frank Fitzek is an Associate Professor in the Dept. of Communication Technology, University of Aalborg, Denmark, heading the Future Vision and Mobile Device group. His current research interests are in the areas of wireless and mobile communication networks, mobile phone programming, cross layer as well as energy efficient protocol design and cooperative networking. Currently Dr. Fitzek is working on robust header compression (ROHC) techniques for WiMAX as well as exploring cooperative networking concepts in WiMAX
