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.

*It transmits multiple signals simultaneously across the wireless transmission paths within separate frequencies to avoid interference.

It uses ultra wide band

Which consists of :

1.High bit rate

2.High security

3.Faster data transmissionGIGABIT WIRELESS PAN NETWORKS

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. 04/11/2313

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.
