$10 Revolutionary Wireless Chip..Bye Bye WiFi, Hello GiFi
The "GiFi" was unveiled today at the Melbourne University-based laboratories of NICTA, the national information and communications technology research centre.
The tiny five-millimeter-a-side chip can transmit data through a wireless connection at a breakthrough five gigabits per second over distances of up to 10 meters. 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.
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.
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
