Germany's Fraunhofer ESK has launched a multi-year research project in collaboration with Lantiq and InnoRoute Gmbh aimed at achieving gigabit broadband rates over existing copper access lines.
The research will explore channel properties in the 300 MHz frequency range over relatively short lengths of existing copper. VDSL2 utilizes frequencies up to 30 MHz.
The project is funded by the Bavarian Research Institute.
