  • significant funder of wireless research.

    In the early 1990s, DARPA was involved in the research on and adoption of asynchronous transfer mode (ATM) technology, as well as research into packet technologies for voice and video. Along with nearly 40 other organizations, DARPA also completed work on the Gigabit Testbed Initiative, an effort by...
  • systems that provide long-reach communications

    In addition to emphasizing the impact of U.S. communications research on C4I (i.e., command, control, communications, computers, and intelligence2), it is also important to briefly note the relevance to C4I of the engineering disciplines. Much of the basic mathematics that underlies telecommunicatio...
  • telecommunications had a clear meaning

    Before the emergence of the Internet and other data networks, telecommunications had a clear meaning: the telephone (and earlier the telegraph) was an application of technology that allowed people to communicate at a distance by voice (and earlier by encoded electronic signals), and telephone servic...
  • the advanced mobile phone system

    Growing consumer demand and the need to make better use of available spectrum resources fueled the development of a second generation of wireless technologies (also commonly referred to as 2G technologies). This second generation marked the transition to a fully digital technology, providing enhance...
  • the biggest contributor to support

    The numbers are not definitive: there might, for example, be some physical sciences work that supports telecommunications, and (similarly uncounted) physical sciences work that supports IT as well. Also, not all of the LSN budget supports networking research per se. For example, the biggest contribu...
