Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip that operates at 60GHz on the CMOS process.
Gi-Fi allows wireless transfer of audio and video data up to 5 gigabits per second.
Gi-Fi is ten times the current maximum wireless transfer rate usually within a range of 10 meters.

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.

The bit rates of Bluetooth is 800 Kbps and Wi-Fi has 11 Mbps
Both are having power consumptions 5mw and 10mw
The lower frequency of operation 2.4GHz.
so, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology.

The core component of a Gi-Fi system is the subscriber station .
It supports standard of IEEE 802.15.3C Wireless PAN
An 802.15.3C based system often uses small antenna at the subscriber station.
It supports line of sight operation.

1.Household appliances :It makes the wireless home and
office of the future.
2.Office appliances : As it transfers data at high speeds
that made work very easy .
3.Video information transfer:We can transfer at a speed of gbps.
4. Inter-vehicle communication system :

Due to less cost of chip so many companies are
looking forward to launch with lower cost.
Specifically, Wireless HD has a stated goal of
enabling wireless connectivity for streaming
High definition content between source devices
and high-definition displays. 05/06/2313
Within five years, we expect Gi-Fi to be the dominant technology for wireless networking.
Gi-Fi can bring wireless broadband to the enterprise in an entirely new way.
