WirelessMAN: Inside the IEEE 802.16 Standard for Wireless Metropolitan Networks

Carl Eklund received his M.S. in engineering physics from Helsinki University of Technology in 1996. He joined the Communication Systems Laboratory of Nokia Research Center in 1998, working mainly on radio protocol design and standardization. In the IEEE 802.16 effort, he chaired the MAC Task Group that developed the IEEE 802.16 medium access control layer (MAC) protocol for IEEE Std 802.16-2001. He also served as the technical editor for the protocol implementation conformance statement (PICS) and test suite structure and test purposes (TSS&TP) specifications for IEEE Std 802.16-2001. Eklund currently is a principal engineer in the Radio Communications Laboratory of Nokia Research Center, Helsinki, Finland. Since October 2005, he has been heading the research and standardization program for WiMAX and IEEE 802.16 in Nokia. Roger B. Marks initiated, in 1998, the effort leading to the formation of the IEEE 802.16 Working Group on Broadband Wireless Access, chairing it since inception and serving as Technical Editor of the group's first two standards. He also serves actively on the IEEE 802 Executive Committee and holds the position of China Liaison Official. Marks is a physicist with the (U.S.) National Institute of Standards and Technology (NIST) in Boulder, Colorado, USA. He received his A.B. in physics in 1980 from Princeton University and his Ph.D. in applied physics in 1988 from Yale University. A Fellow of the IEEE and an IEEE Distinguished Lecturer, Marks developed the IEEE Radio and Wireless Conference and chaired it from 1996 through 1999. He is the author of over 90 publications and the recipient of numerous awards, including the Individual Governmental Vision Award from the Wireless Communications Association and the IEEE Technical Field Award in measurement technology. He has received the U.S. Department of Commerce Gold, Silver (three times), and Bronze Medals. Subbu Ponnuswamy was one of the early participants in the IEEE 802.16 Working Group and a contributor to the IEEE 802.16 and IEEE 802.11 standards. He is also a coauthor of a WiMAX course for development engineers, offered by Doceotech. He has many years of industry experience in the design and development of wireless local area network (LAN) and metropolitan area network (MAN) products, including those based on the IEEE 802.16 and IEEE 802.11 standards. As the director of engineering at Kiwi Networks, Ponnuswamy led the design and development of interference-resilient IEEE 802.16 and IEEE 802.11 systems in the license-exempt bands for indoor and outdoor applications. He also led IEEE 802.11 MAC application-specific integrated circuit (ASIC) and software development at Vivato for smart antenna systems. During his tenure at Malibu Networks, he designed and developed a qualityof-service-centric broadband wireless MAC. He has also held various technical positions with Honeywell, Sequent Computer Systems, and Lincom Wireless. He is currently with Aruba Networks. Ponnuswamy is the author of many publications and patents in the areas of wireless communication, realtime systems, and multiprocessor communication networks. He graduated with an M.S. in computer engineering from Wayne State University and a B.E. in electronics and communication engineering from the University of Madras, India. He is a member of the Association for Computing Machinery (ACM) and the IEEE Communications Society. Kenneth L. Stanwood is president and chief executive officer of Cygnus Communications, which makes products for wireless multimedia distribution. He was previously chief technology officer of Ensemble Communications, which produced local multipoint distribution services (LMDS) equipment and provided key technology to IEEE 802.16 and WiMAX. As a representative of Ensemble, Stanwood was one of the founders of the WiMAX Forum and served on its board of directors. Stanwood is vice-chair of the IEEE 802.16 Working Group and has been involved with IEEE 802.16 and the European Telecommunications Standards Institute (ETSI) Broadband Radio Access Networks (BRAN) Technical Committee for over 6 years. He was a primary designer of the IEEE 802.16 MAC. He holds 11 patents and has numerous patent applications, all related to broadband wireless access. He received his master's degree from Stanford University. Nico J.M. van Waes received an M.S.E.E from the Technical University Delft in the Netherlands in 1994 and a Ph.D. from New Jersey Institute of Technology in 1998. He joined the Wireless Router Division of Nokia Networks in 1999 as a systems engineer, working primarily on physical layer (PHY) and radio frequency (RF) issues as well as standardization. From 1999 till 2004, van Waes held various standards-related public positions such as chief technical editor of IEEE Std 802.16a, IEEE P802.16.2a, and early versions of IEEE P802.16d; area coordinator and editor for ETSI BRAN HiperMAN; and chair of the OFDM Forum's fixed wireless access (FWA) working group. From 2004 till 2005, he led Nokia Research Center's efforts in IEEE P802.11n standardization. Since early 2006, van Waes has been a manager with Nokia IPR, responsible among others for the IEEE 802.16 and IEEE 802.11 portfolios. He has half a dozen patents filed and is the author of several published papers.
