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.
