NTU and I²R scientists invent revolutionary chipset for high-speed wireless data transfer

25.05.2012
Data can now be transmitted 1,000 times faster than Bluetooth
Here is a new microchip that can transfer data the size of 80 MP3 song files (or 250 megabytes) wirelessly between mobile devices, in the flick of a second.

Or how about transferring a typical 2-hour, 8-gigabyte DVD movie in just half a minute compared to 8.5 hours on Bluetooth?
Such unprecedented speeds on the wireless platform are now a reality as scientists from the Nanyang Technological University (NTU) and A*STAR’s Institute for Infocomm Research (I²R) have developed a revolutionary microchip that can transmit large volumes of data at ultra-high speeds of 2 Gigabits per second (or 1,000 times faster than Bluetooth^).

The chipset employs wireless millimetre-wave (mm-wave) technology to transmit large packets of information while consuming little power. This enables low-power applications, like smart phones and tablets, to transmit/receive data between platforms, like projectors and TVs, without the need for cables for the very first time.
“The demand for ultra high-speed wireless connectivity has fuelled the need for faster data transfer rates. Unfortunately, current technologies are unable to meet these stringent demands. The NTU-I2R team, being at the cutting edge of research and development, has successfully demonstrated an integrated 60GHz chipset for multi-gigabits per second wireless transmission,” said Professor Yeo Kiat Seng, the Principal Investigator of the project and Associate Chair of Research at NTU’s School of Electrical & Electronic Engineering.

How the VIRTUS chipset works

Named the VIRTUS chipset, it consists of three components: an antenna, a full radio-frequency transceiver (developed by NTU) and a baseband processor (developed by I²R). The antenna is connected to the transceiver, which filters and amplifies the signals. It then passes the signals to the baseband processor, which comprises non-linear analog signal processing and unique digital parallel processing and decoder architecture – key to lower power consumption.

The team of scientists from NTU and I²R is the first in the world to successfully put together an integrated low-power 60 Gigahertz (GHz) chipset solution consisting of the three components, making it one step closer to commercialisation. It is also the first team to demonstrate one of the technology’s applications – in the form of a high-definition wireless video stream.

The VIRTUS chipset has garnered 16 international patents. It has also been featured in 51 top-tier international journal and conference papers, on top of its other international accolades such as two best paper awards and two best chip design awards.
“This ground-breaking mm-wave integrated circuit (IC) technology will have significant commercial impact, enabling a wide range of new applications such as wireless display, mobile-distributed computing, live high-definition video streaming, real-time interactive multi-user gaming, and more,” added NTU’s Prof Yeo, who is also founding director of NTU’s VIRTUS IC Design Centre of Excellence.

The collaboration, which began in December 2009, was funded by A*STAR’s technology transfer arm, Exploit Technologies Pte Ltd. The team has been approached by leading players and global brand names in the electronics and semiconductor industry to develop the chipset commercially. It will also showcase the technology at a leading technical innovation event in June this year – Computex (Taiwan).

About Nanyang Technological University

A research-intensive public university, Nanyang Technological University (NTU) has 33,500 undergraduate and postgraduate students in the colleges of Engineering, Business, Science, and Humanities, Arts, & Social Sciences. In 2013, NTU will enrol the first batch of students at its new medical school, the Lee Kong Chian School of Medicine, which is set up jointly with Imperial College London.

NTU is also home to four world-class autonomous institutes – the National Institute of Education, S Rajaratnam School of International Studies, Earth Observatory of Singapore, and Singapore Centre on Environmental Life Sciences Engineering – and various leading research centres such as the Nanyang Environment & Water Research Institute (NEWRI) and Energy Research Institute @ NTU (ERI@N).

A fast-growing university with an international outlook, NTU is putting its global stamp on Five Peaks of Excellence: Sustainable Earth, Future Healthcare, New Media, New Silk Road, and Innovation Asia.

Besides the main Yunnan Garden campus, NTU also has a satellite campus in Singapore’s science and tech hub, one-north, and is setting up a third campus in Novena, Singapore’s medical district.

Im Focus: LaserTAB: More efficient and precise contacts thanks to human-robot collaboration

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.

Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
