, Kharagpur, Distinguished Alumni Award (2012), and the Schwarzkopf Prize for Technological Innovation (2008). Dr. Raychaudhuri is a leading researcher/technologist in the field of wireless networking based on his sustained technology contributions and leadership over the past 38 years. He is acknowledged as a pioneer who helped bring broadband wireless access technology from concept to reality in the 1990s. This is a technology domain (high speed WLAN, WiMax, etc.) which has made it possible for hundreds of millions of people connect to the Internet. Prof. Raychaudhuri is also recognized today in the US academic research community as a forward-looking network architect who is leading National Science Foundation supported R&D initiatives to innovate the future mobile Internet from a "clean slate" perspective (FIA), and to develop open, programmable wireless and network testbeds (ORBIT, GENI and COSMOS). Finally, as director of WINLAB since ~2001-, he has led development of an internationally acclaimed academic research center specializing in wireless technology, and in this capacity plays a visible leadership role in advancing basic research and education in the field. Dr. Raychaudhuri has also been active in technology entrepreneurship, helping to incubate startup companies in the wireless networking and media areas over the past 18 years. He serves as technical advisor or board member to several new technology companies, and has previously served on the advisory council of the NJ Economic Development Authority's Edison Innovation Fund. He has also served as editor of several leading journals including ''

Notable achievements

Notable technology innovations by Prof. Raychaudhuri include design and implementation of one of the world's first broadband wireless local area networks. He published his concept for an ATM-based broadband wireless access network in a landmark paper (in ''IEEE J. Selected Areas in Communications'', 1992) - this paper went on to become the 2nd most highly-cited journal paper in the communications field between 1990 and 2005 according to ISI Thomson-Reuters. Dr. Raychaudhuri's research group at NEC C&C Laboratories in Princeton subsequently demonstrated the feasibility of reliable 25 Mbps mobile services in the 5 GHz band and successfully conducted proof-of-concept field trials as early as 1998. Other important research results in his career include design and prototyping one of the earliest VSAT (very small aperture terminal) data networks during the 1980s. This technology enabled the first generation of data networks in the US and is still used to provide Internet access to remote areas all over the world. In the early 1990s he was a co-lead for a multi-company research team which designed one of the first

in 1991, significantly influencing the “ATSC” digital TV standard in wide use today. After joining Rutgers as a Professor, Dr. Raychaudhuri collaborated with Ivan Seskar (Chief Technologist at WINLAB) to build the "ORBIT radio grid testbed" the world's largest open research testbed for evaluation of future wireless networking protocols. During the period 2010-18, his group at WINLAB has also developed a novel clean-slate mobility-centric future Internet architecture called “MobilityFirst”, which proposes a new “named object” approach to Internet routing based on the use of globally unique identifiers (GUIDs) in place of conventional IP addresses. More recently, his research group at WINLAB has been leading a major NSF project funded under the Platforms for Advanced Wireless (PAWR) program aimed at deploying the city-scale, open/programmable COSMOS testbed in New York City for research on next-generation wireless networks with edge cloud capabilities.
