Aussie scientists unveil 5Gps turbocharged wireless chip

Transmitter and receiver on a single chip

The world's first transceiver integrated on a single chip that operates at 60GHz on the CMOS (complementary metal-oxide-semiconductor) process, which is the most common semiconductor technology, was announced today by NICTA.

The development will enable the truly wireless office and home of the future, according to NICTA which is Australia's Information and Communications Technology (ICT) Research Centre of Excellence.

As the integrated transceiver developed by NICTA is extremely small, it can be embedded into devices.

The breakthrough will mean the networking of office and home equipment - without wires - will finally become a reality.

Researchers from NICTA's gigabit wireless project, which is based out of NICTA's Victoria research laboratory, are the first in the world to have developed an integrated transceiver, a complete transmitter and receiver, on a single chip at 60GHz on CMOS.

NICTA CEO, Dr David Skellern, said this technology breakthrough will enable the wireless transfer of audio and video data at up to five gigabits per second, 10 times the current maximum wireless transfer rate, at one-tenth the cost.

"Our team, which includes 10 PhD students from the University of Melbourne, has overcome some significant challenges in developing this breakthrough technology," he said.

"Developing very high frequency radio components in a standard CMOS process and then integrating those components on a single chip has posed challenges in dealing with the inherent limitations of that process for radio circuits.

"Now that NICTA researchers have successfully addressed these challenges, the ICT industry will soon have access to low cost, low power and high broadband chips that will be vital in enabling the digital economy of the future."

NICTA gigabit wireless project leader Professor Stan Skafidas said the design and development of the world's first 60GHz transceiver integrated on a single CMOS was the result of a three-year research effort.

NICTA's research involved a close collaboration with leaders in the global semiconductor industry.

The technology was developed using the IBM 130nm RF CMOS process.

Skafidas said the collaborators IBM, Synopsys, Cadence, Anritsu, Agilent, Ansoft and SUSS MicroTec have been critical to the success of the project.

"Our innovative design methodology and access to leading design, test and measurement, and fabrication technology has allowed us to deliver this world-first success," he said.

NICTA researchers chose to develop this technology in the 57-64GHz unlicensed frequency band as the millimetre-wave range of the spectrum makes possible high component on-chip integration as well as allowing for the integration of very small high gain arrays.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
