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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
