Abstract |
|
The quality of life and on-line economy depends on the
availability of ubiquitous low-cost broadband access. Demands on
end-user bit-rate continue to increase as new broadband services emerge.
Fibre-to-the-home (FTTH) could fulfil these needs, but investment costs,
required to replace the existing multitude of last-segment copper-based
infrastructure, are too prohibitive, even seen over long investment
times. Therefore, there is a strong need for a more cost-effective
solution, offering FTTH rates, but at much lower investment costs. DSL
technology opened the market for broadband Internet access whereas Very
high speed Digital Subscriber Line (VDSL2) fed by Fibre-To-The-Cabinet
is now opening the market for IPTV services. A next step in fibre
extension calls for a new enabling technology from the last distribution
point. A 4th-generation DSL technology, approaching gigabit-rates via
existing copper wiring, could be deployed from these points, e.g.
basements, poles, street corner or footway boxes. Such a technology is
lacking and very challenging to develop, since telephony wire was
designed for voice-band frequencies.
The goal of the 4GBB project is to provide
proof-of-concept for an ultimate DSL technology, which will close the
gap between VDSL2 and the long term scenario of FTTH. The 4th generation
of DSL will offer truly high bit-rate broadband at low costs for all. It
will facilitate new services and strengthen the industry in broadband
access. |
