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:

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
