This opens up the possibility of using the 60 GHz band for applications requiring rapid data transfer, such as uncompressed transmission of HDTV, fast Internet access for passengers on airplanes and trains, and applications in medical technology and TV studios.
Previous experiments with 60 GHz were based on transmitters and receivers alone. This means that data transmission is disrupted when something passes the antenna lobe, which is not acceptable for wireless networks. Now these scientists have used a technology called Multiple-Input-Multiple-Output, MIMO. With this technology antennas do not need to be lined up and previous problems with shadowing, interference, and blocking are eliminated.
With MIMO technology, several transmitters and receivers are used for transmission of the signal; the same signal is transmitted with a slight time delay to the receiver antennas, with the signal taking different paths. The signals are spliced together using special algorithms in the receiver so that the correct information can be extracted. Through a winning combination of findings from several years of research on MIMO algorithms and baseband electronics, and many years of experience from designing compact multifunctional MMIC (Monolithic Microwave Integrated Circuits) for 60 GHz, these scientists have successfully managed to pool their knowledge and construct the MIMO system.
The 60 GHz band is a license-free frequency band with several GHz of bandwidth, which opens up the possibility of wireless communication with transmission speeds of several Gbit per second.For further information, please contact:

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
