$10 chip puts Australia on the fast track
A new silicon chip developed in Melbourne is predicted to revolutionise the way household gadgets like televisions, phones and DVD players talk to each other.
The tiny five-millimetre-a-side chip can transmit data through a wireless connection at a breakthrough five gigabits per second over distances of up to 10 metres. An entire high-definition movie from a video shop kiosk could be transmitted to a mobile phone in a few seconds, and the phone could then upload the movie to a home computer or screen at the same speed.
The "GiFi" was unveiled today at the Melbourne University-based laboratories of NICTA, the national information and communications technology research centre.
"I believe in the longer term every consumer device will have this technology," said project leader, Professor Stan Skafidas, who with his team spent almost a decade developing the chip.
Hotly contested area
Short-range wireless technology is a hotly contested area, with research teams around the world racing to be the first to launch such a product.
Professor Skafidas said his team is the first to demonstrate a working transceiver-on-a-chip that uses CMOS (complementary metal-oxide-semiconductor) technology - the cheap, ubiquitous technique that prints silicon chips.
This means his team is head and shoulders in front of the competition in terms of price and power demand. His chip uses only a tiny one-millimetre-wide antenna and less than two watts of power, and would cost less than $10 to manufacture.
It uses the 60GHz "millimetre wave" spectrum to transmit the data, which gives it an advantage over WiFi (wireless internet). WiFi's part of the spectrum is increasingly crowded, sharing the waves with devices such as cordless phones, which leads to interference and slower speeds.
But the millimetre wave spectrum (30 to 300 GHz) is almost unoccupied, and the new chip is potentially hundreds of times faster than the average home WiFi unit. However, WiFi still benefits from being able to provide wireless coverage over a greater distance.
Victoria's minister for information and communication technology, Theo Theophanous, said it showed Victoria was at the cutting edge of IT innovation.
He praised the 27-member team which worked on the development of the chip. The high-powered team included 10 PhDs students from the University of Melbourne and collaborated with companies such as computer giant IBM during the research.
"This new technology will dramatically change the way data and content-rich information is managed in the office and the home, as well as enabling new applications," Mr Theophanous said. "The possibilities are endless."
'Several breakthroughs in one'
For Professor Skafidas, the chip is several breakthroughs in one. It includes a world-first power amplifier that is only a few microns wide, with a micron being one 300th the width of a human hair.
It also has world's first signal mixing and filter technology, and a switch that isolates the transmitter and receiver so they do not interfere with each other.
There is about another year's worth of work on the chip before it is ready to be marketed to the public, he said, and the team still needs to develop technology that injects data into the transceiver.
Professor Skafidas said he sees several ways the technology could be put to use.
It could be used to transfer data-rich content such as video around the home between different storage and display devices, and it could help turn a mobile device into a "shopping cart" for data.
A mobile device could also become a fully-fledged computer through the GiFi, simply by placing it near similarly-equipped peripherals such as a screen, extra storage, optical drives, a keyboard and mouse
