Researchers at Melbourne University in Australia have unveiled a new wireless chip which allows for high-speed short range data transfers. GiFi, as it is called, offers data speeds of up to 5 gigabits per second over a 10 meter distance, and would, in theory, allow a full-length high definition movie to be transferred between two devices in seconds.
The chip measures 5mm square and is manufactured using existing complementary metal-oxide-semiconductor (CMOS) technology, the same system that is currently used to print silicon chips. This means it would cost roughly $10 to manufacture each chip, which uses less than 2 watts of power to run with its tiny, 1mm wide antenna. GiFi operates on the 60GHz frequency band, which is currently mostly unused. This offers GiFi a distinct advantage over current WiFi implementations, which share spectrum with cordless phones, Bluetooth, and other devices.
GiFi will not be ready for the public until 2009, though there are already several possible usage situations. The technology could be used to allow high-speed connectivity between consumer goods, such as television sets, home stereos, and remote storage devices. Cell phones could use the technology to quickly transfer and store large multimedia files.
