Broadband: the last mile

摘要

The regulatory and service drivers that are prerequisites for local access evolution to the broadband integrated services digital networks are discussed. A tutorial on the state of the art in relevant technologies is presented, and it is shown that many of the technologies are not yet mature. The broadband technologies discussed are analog cable television systems, optical fiber, optical amplifiers, optical receivers, transceivers, and image compression systems. Regulatory considerations include bandwidth on demand and competition.
