Gi-Fi or Gigabit Wireless is the world's first integrated single-chip transceiver that operates at 60GHz in the CMOS process. It will enable wireless transfer of audio and video data to a maximum of 5 gigabits per second, ten times the current maximum wireless transfer rate, at one tenth of the cost. NICTA researchers have chosen to develop this technology in the 57-64GHz unlicensed frequency band. As the millimeter wave range of the spectrum enables the integration of high-level components on the chip, as well as the integration of high-gain arrays very small. The available spectrum of 7GHz results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 meters.

The new technology is expected to revolutionize the way household appliances talk to each other. It was developed by the laboratories of the University of Melbourne of NICTA (National ICT Australia Limited), the Center for Excellence in Research in Information and Communication Technologies of Australia.

Gi-Fi helps push wireless communications to a faster drive. For many years the cables ruled the world. Optical fibers played a key role for their higher bit rates and faster transmission. But the installation of the cables caused greater difficulty and therefore led to wireless access. The main of this is Bluetooth which can cover 9-10mts. Wi-Fi followed with coverage area of 91mts. No doubt, the introduction of Wi-Fi wireless networks has proven to be a revolutionary solution to the "last mile" problem. However, the original limitations of the standard for data exchange rate and reach, the number of channels, the high cost of infrastructure have not yet made it possible for Wi-Fi to become a total threat to cellular networks , On the one hand, on the other. But the continued search for even better technology despite the substantial advantages of today's technologies led to the introduction of new, more up-to-date standards for data exchange, ie Gi-Fi.

Gi-Fi or Gigabit Wireless is the world's first integrated single-chip transceiver that operates at 60GHz in the CMOS process. It will allow the wireless transfer of audio and video data up to 5 gigabits per second, ten times the current maximum wireless transfer rate, to one tenth of the cost, usually within a range of 10 meters. It uses a 5mm square chip and a 1mm wide antenna that burns less than 2 watts of power to transmit data wirelessly over short distances, just like Bluetooth.
