Stand-Alone Terrestrial and Satellite Networks for Nationwide Interoperation of Broadband Networks

摘要

The current status of fiber optic and related broadband terrestrial networks is reviewed. That includes summaries of link and switch capabilities as well as present and future standards for broadband systems. In the domain of communication satellites, both existing and advanced future technologies are described. Advantages and disadvantages of both terrestrial and satellite stand-alone networks are discussed from the service survivability and restoration point of view. The presented material is largely technical. As a consequence, the report does not address such important nontechnical issues as economics, costs, policies, and the regulatory environment.
