Gandalf – the research project, not the fabled wizard – has developed groundbreaking technology to boost existing dsl data rates a thousand-fold and wifi by up to a hundredfold. The technique allows data to flow seamlessly over both wireless and fixed-line communications, a world first when initially reported by ICT Results in 2005.
The culmination of nearly five years of EU-funded research – first with Obanet, then Gandalf – the new technique uses an optical feeder (“photonic beamformer”) to shoot data over both cable and wireless networks.
By simplifying the electronics involved at both the transmitter and receiving ends, this dual format is good news for operators because it is relatively cheap to deploy. In principle, cost savings could then be passed on to bandwidth-hungry end-users, whether in homes or offices.Counting on the savings
Most significantly perhaps, Gandalf’s then coordinator went on to suggest, the system would give operators access to more clients without having to undergo costly public works to lay new fibre optic cable. Existing cable could be used to relay data to the closest access node to clients’ homes before being converted into a wireless signal.
Following a period of successful testing, the Gandalf project concluded at the end of 2005. But ICT Results has received reports that a spin-off company, DAS Photonics, has been created to exploit the results and techniques developed in Obanet and Gandalf.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
