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 IEE 802.11 standards marketed under the trademark Wi-Fi.
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.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. Some press reports called this "GiFi". It was developed by Melbourne University-based laboratories of NICTA (National ICT Australia Limited), Australia s Information and Communications Technology Research Centre of Excellence.
In 2009, the Wireless Gigabit Alliance was formed. It used the term "WiGig" which avoided trademark confusion.
Why GI-FI
The reason for pushing into Gi-Fi technology is because of
slow rate,
high power consumption,
low range of frequency operation
of earlier technologies i.e. , Bluetooth and Wi-Fi.
Currently Using Technologies
Bluetooth
Wi-Fi
Features of Gi Fi Technology
High speed of data transfer
Low power consumption
High security
Cost effective
Small size
Applications of Gi Fi Technology
In wireless PAN networks.
Inter-vehicle communication system.
Huge data file transfer.
Office appliances.
Video information transfer.
