The business of telecommunications is undergoing a period of change
driven by changes in regulation, increasing demands for services and the
development of new access technologies. The market structure of
telecommunications is evolving rapidly as new and existing players
strive to compete in an increasingly volatile market, while the advent
of new data services is placing greater demands on the network as
operators strive to offer new broadband services. Underpinning much of
this change is the access technology itself, not only in the
transitional form of copper twisted pairs, but also increasingly through
the use of new fibre, radio and copper systems. The dominant cost of
most telecommunication networks is the access network itself, which
typically can demand up to 80% of the total investment required.
This book presents an overview of the access network and discusses the
technologies that are available. It begins with an introductory chapter
defining terms and technologies and goes on to discuss each technology
in turn, not only from a technology viewpoint but with a view on how it
might be best deployed. Chapters are also included on planning systems,
network management, DSL, fibre access networks, optical access networks,
fixed wireless access, broadband, wireless LANs, UMTS, and SDH in the
access network.
