Chip offers 5Gbps short-range wireless

NICTA GiFi Chipset

A new wireless technology has been developed that should serve as an extremely fast replacement for technologies such as Bluetooth and ultra-wideband (UWB), says Australian research group NICTA. Nicknamed GiFi, the process would use a chip (not pictured) that transmits at an extremely high 60GHz frequency versus the 5GHz used for the fastest forms of Wi-Fi. The sheer density of the signal would allow a chip to send as much as five gigabits per second. While the spectrum would limit the device to the same 33-foot range as Bluetooth or UWB, it could theoretically transfer an HD movie to a cellphone in seconds, the researchers claim.

The technology could also be used for beaming full HD video in real-time and could be used by notebooks and other computers to wirelessly connect virtually all the expansion needed for a docking station, including a secondary display and storage. Mixing and signal filtering would keep the signal strong versus the longer-ranged but slower and more drop-prone Wi-Fi option of today.

NICTA does not expect a production-grade chip to leave the development stage until early 2009 but notes that any future chip would likely cost about $10 or less to build. This and a small design would allow cellphones and other small devices to add the technology without significantly drive up the price, according to the company. The change opens the possibility of a successor to UWB and its related technology Wireless USB, which matches the same range but roughly the same 480Mbps peak speed of its wired equivalent.

    you're all idiots

    The obvious use for this is for wireless monitors. Its one less cable on everyone's desk and makes media-center style apps a waste of time as you can just use your laptop wirelessly to send HD video to your TV.

    All I can say is.....

    WOW! That's fast.
