Ubiquitous, higher-performance, more-affordable broadband access that enables richer, more interactive applications, including applications in such important areas as health care and education;Telepresence and telecollaboration environments that reproduce a local space at a distance and enable spatially separated individuals or teams to work more readily in concert;Public safety networks that offer higher mobility, better adaptation to harsh and changing conditions, and increased resiliency to damage;Adaptive/cognitive wireless networks that enable higher-performance communications, make more efficient use of radio spectrum, and complement or supplant today’s chiefly wired networks;Location-based wireless networks that provide information and services tailored to the local environment;
Self-organizing sensor networks that have large numbers of nodes, are energy efficient, and have self-organizing capabilities, which would enable ubiquitous, cheap monitoring of the environment and weather, sensing of biological or chemical agents, and monitoring of facilities; and New semiconductor devices that enable higher performance and new forms of communications and computing.
Major innovation in telecommunications has always depended on the industry’s ability to make major architectural shifts. Telecommunications networks are large, complex systems
whose reliability, security, and evolvability are dependent on the development of coherent and well-conceived architectural concepts. Historical examples within the public telephone network of such major architectural shifts include direct-distance dialing, digital transmission and switching, and the incorporation of cellular telephony into the public telephone network. The Internet is another example of a major architectural advance, one made possible by a multiyear research effort funded by the federal government for the first couple of decades (largely on behalf of military and internal research applications).
