Research for Development of Future Interactive Generations of Hybrid Fibre Coax Networks (ReDeSign)
Start date: 01 Jan 2008, End date: 30 Jun 2010 PROJECT  FINISHED 

A reliable and cost efficient broadband infrastructure is vital for the economy and society of the 21st century. Broadband access based on hybrid fibre-coax (HFC) networks stimulates the accretion of broadband markets and features strong service innovation. The further development of HFC architecture and transmission technologies is essential for maintaining the ability to meet the future requirements of broadband users and to remain competitive with alternative access technologies.The aim of this project is to further evolve HFC network architectures and transmission technologies used in these networks by creating a smooth migration path towards future infrastructure concepts. In its technical objectives, the project addresses in a first scenario the evolution of the current HFC access network with state-of-the-art RF radio transmission technology. The development of related technologies will be performed through a liaison with the Digital Video Broadcasting (DVB) project which has recently started to compose Commercial and User Requirements for the second generation DVB for cable (DVB-C2) system. The timing of the project is aligned to the roadmap of the industry and the organisations involved in the DVB-C2 work. In a second scenario ReDeSign researches transmission techniques which accelerate the deployment of HFC bidirectional network investments towards more cost efficient, robust, and high quality HFC networks with higher orders of bandwidth capacity including deep fibre architectures where economically feasible. The objectives will be achieved via close alignments with the DVB project and the recognized standards body for cable CENELEC. Chairmen of DVB Technical Module, DVB-C2 Commercial Moudle and CENELEC TC 209 are members of the consortium. An operators Forum will be set up for information gathering and results dissemination purposes. First MSOs (KabelDeutschland, Telenor, Vectra) have already indicated their interest in supporting this activity
