--> F Letter from Vice President Albert Gore March 6, 1995 Dear Dr. Branscomb: On behalf of the Administration, I want to thank you for the work that you and your colleagues are doing in connection with the National Research Council's "NII 2000" Committee. There is one issue that the Administration is particularly interested in that I hope the Committee can shed some light on. Although the Administration's NII policy is technology neutral, we would like to see an NII that allows individuals to be producers as well as consumers of information, that enables "many to many" communication, and that provides a "general purpose" infrastructure capable of supporting a wide range of services. The NRC's previous report on the NII, Realizing the Information Future , concluded that some U.S. companies may invest in an infrastructure that is capable of providing one-way video delivery but not a broader range of services. For this reason, it would be very helpful to have an objective assessment of the capabilities of different residential broadband architectures (e.g., hybrid fiber-coax, fiber-to-the-curb, wireless alternatives) being deployed by the private sector. The NRC could select a representative sample of applications and services (videoconferencing, high-speed access to the Internet or other on-line services, telecommuting, distance learning, grassroots electronic publishing) and determine whether the

OCR for page 249
--> broadband architectures under consideration will be capable of supporting these applications. Clearly, market considerations will drive the technology and architectural decisions of U.S. telecommunications providers. Futhermore, a network that may originally support a limited range of services can be incrementally upgraded in response to consumer demand. The Administration has absolutely no interest in mandating a particular technology. This would be completely contrary to the Administration's NII philosophy. However, we are interested in working cooperatively with industry and academia to promote a shared vision of a versatile, general purpose infrastructure with a "Jeffersonian" architecture. We would welcome any concrete suggestions the Committee may have for advancing these goals. Thank you again for your work on this important NRC Committee. Sincerely, (signed) Al Gore
