The evolution of copper access transmission

摘要

The great telecommunication success story of the last few years has been the mass take-up of the Internet and the world wide web. Its popularity as a medium for communication, entertainment and employment has resulted in astonishing growth. One complaint, however, is heard time and time again: its slowness. Watching a web page slowly load a picture or video clip has resulted in the cynical replacement of 'world wide web' with 'world wide wait'. Modem manufacturers have responded with faster modems, but the technology is nearing its limits and a fundamentally new approach is required for a substantial increase in speed.
