4GBB: 4th Generation Broadband Systems
The 4GBB was a project under the EUREKA CELTIC cluster. It started in 2009 and ended in June 2012. It was coordinated by Ericsson AB, Sweden and had 12 partners from 6 countries.

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.
