报告摘要:Over the ages, research in wireless communications has been evolving through a quest for answers to the fundamental questions: why, what and how? Why do people, separated by physical distances, cannot hear each other talking? Alexander Graham Bell’s invention of the telephone was driven by this curiosity; so was Guglielmo Marconi’s telegraphic signalling across the Atlantic Ocean in 1901.

Channel impairments and multiple access interference limit the capacity and the geographical coverage of a wireless system. Radio resource management is essential to achieve high system utilization, while global communication necessitates the interworking of different telecommunication domains. Interworking of different domains, however, has profound ramifications on the formulation and linkage of the building blocks to construct an information transport platform. This talk will first provide an exposition and a critical look at future evolution of wireless communications and networking, beginning with a brief historical perspective of wireless technology, a look at the obstacles posed by nature and the challenges facing the designers, and then an examination of power distribution/allocation mechanisms that are essential functions of radio resource management.
