Gi-Fi or gigabit wireless refers to a wireless communication at a data rate of more than one billion bits (gigabit) per second.

By 2004 some trade press used the term "Gi-Fi" to refer to faster versions of the IEEE 802.11 standards marketed under the trademark Wi-Fi.[1]

In 2008 researchers at the University of Melbourne demonstrated a transceiver integrated on a single integrated circuit (chip) that operated at 60 GHz on the CMOS process.[2] It will allow wireless transfer of audio and video data at up to 5 gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost. Researchers chose the 57–64 GHz unlicensed frequency band since the millimetre-wave range of the spectrum allowed high component on-chip integration as well as the integration of very small high gain arrays. The available 7 GHz of spectrum results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 metres.[2] Some press reports called this "GiFi".[3][4] It was developed by Melbourne University-based laboratories of NICTA (National ICT Australia Limited), Australia’s Information and Communications Technology Research Centre of Excellence.[3]

In 2009, the Wireless Gigabit Alliance was formed to promote the technology. It used the term "WiGig" which avoided trademark confusion.[5]
