* Introduction to Gi-Fi :

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.

*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.

*Comparison between Bluetooth & Wi-Fi

7

*Disadvantages of Bluetooth & 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.

*Architecture of Gi-Fi

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.

FUNDAMENTAL TECHNOLOGIES IN 802.15.3C

*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 rate2.High security3. Faster data transmissionGIGABIT WIRELESS PAN NETWORKS

*FEATURES OF Gi-Fi

High speed of data transferLow power consumptionHigh securityCost effectiveSmall sizeQuick deploymentHighly portable, high mobility

11

*Applications of Gi-Fi

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 :

*Applications Cont...

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.13

* Technology Considerations

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.
