Abstract:
There is a continuing quest for increasing the data transmission rate in wireless systems. Cellular mobile radio systems have advanced from second generation digital technology with limited data capability to third generation systems with data transmission rates on the order of a few megabits per second and on to fourth generation systems with goals of even higher data rates. Wireless local area networks (WLANs) based on various versions of IEEE 802.11 standards and known collectively as WiFi, have evolved from having data transmission rates of several megabits per second to hundreds of megabits per second.

He received an Honorary Doctor of Science from the University of Nebraska in 1983. From 1960 to 1963 he did wireless communications system design at Wright-Patterson AFB, Ohio. From 1963 to 1968 he was at Stanford University doing research on tunnel diode amplifiers, microwave propagation, and electronically steerable arrays that evolved into multisensor signal processing for “smart” antennas. From 1968 to 1973 his research at Bell Laboratories, Holmdel, New Jersey, on mobile radio channels and high-capacity mobile radio systems provided important input to early cellular mobile radio systems, and is continuing to contribute to the evolution of digital cellular radio and other wireless systems. From 1973 to 1983 he was supervisor of a group at Bell Laboratories that did innovative propagation and system research for millimeter-wave satellite communications. In 1978 he pioneered radio system and propagation research for wireless personal communications systems. At Bell Laboratories in 1983 he organized and became head of the Radio and Satellite Systems Research Department that became a division in Bell Communications Research (Bellcore) in 1984 with him as division manager. It again became a department in 1991 with him as executive director. At Bellcore he championed, led, and contributed to research on all aspects of wireless personal communications and wireless loops, including Universal Digital Portable Communications (UDPC) and CDMA systems. He was instrumental in evolving the extensive research into the U.S. Standard for the Wireless or Personal Access Communications System (WACS or PACS). In September 1993 he became a professor of electrical engineering and director of the Center for Telecommunications at Stanford University where he started and continues to pursue research and teaching of wireless communications. He was appointed Harald Trap Friis Chair Professor of Engineering in 1994. He is a member of the National Academy of Engineering, and is a Fellow of the AAAS and the Radio Club of America. He was awarded the IEEE 1993 Alexander Graham Bell Medal “for pioneering and leadership in personal portable communications” was a co-recipient of the 1983 International Marconi Prize in Electromagnetic Wave Propagation (Italy); and received the Bellcore Fellow award in 1991, the IEEE 1985 Morris E. Leeds Award, the IEEE Third Millennium Medal 2000, the IEEE Communications Society 1992 L. G. Abraham Prize Paper Award and 1990 Communications Magazine Prize Paper Award, and the 1983 IEEE Vehicular Technology Society paper of the year award. He received an Alumni Achievement Award from the University of Nebraska in 2002. He is a member of Commissions B, C, and F of USNC/URSI, was an Associate Editor of IEEE Transactions on Antennas and Propagation (1983–1986), a member of the Administrative Committee of the IEEE Antennas and Propagation Society (1986–1988), and a member of the URSI Intercommission Group on Time Domain Waveform Measurements (1982–1984). He is author or coauthor of over 250 technical papers and conference presentations, including many invited and several keynote addresses, and books. He has been granted 19 patents. He is a member of Sigma Xi, Sigma Tau, Eta Kappa Nu, and Phi Mu Epsilon, and is a Registered Professional Engineer in Ohio and Nebraska.
