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.
The 4GBB project, formed by leading European industry and academia, will develop advanced cable-models, high-performance wideband transmission techniques, as well as multi-channel communication and resource management methods to enable ultimate DSL. 4GBB is expected to impact standards regarding wideband cable models, transmission schemes and spectrum allocation, and to initiate a new 4GBB standard.
