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.7

EXISTING SYSTEMCOMPARISON BETWEEN BLUETOOTH & WI-FI

Disadvantages of Bluetooth & Wi-Fi

The bit rates of Bluetooth is 800Kbps and Wi-Fi has 11Mbps

Both are having power consumptions 5mw and 10mw

The lower frequency of operation 2.4GHz.For transferring large amount of videos, audios, data files take hours of time.

So, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology

WHY GI-FI ?

The reason for pushing into Gi-Fi technology is because of

slow rate,high power consumption,low range of frequency operations

of earlier technologies i.e. Bluetooth and Wi-Fi.

Architecture of Gi-Fi :

The core components of a GI-FI system is the subscriber station which available to several access points .

It is based on standards of IEEE 802.15.3C

The wireless span is computer network used for communication among computer devices.

An 802.15.3c based system often uses small antenna at the subscriber station. It supports line of sight operation.

13

FUNDAMENTAL TECHNOLOGIES IN 802.15.3C :

It transmits multiple signals simultaneously across the wireless transmission paths to avoid interference.

It uses ultra wide band.

Which consists of :

1. High bit rate

2. High security

3. Faster data transmission

WORKING OF GI-FI

USE OF TIME DIVISION DUPLEX FOR BOTH TRANSMISSION AND

RECEIVING.

CONVERSION OF DATA FROM IF RANGE TO RF60GHZ RANGE

THE INCOMING RF SIGNAL IS FIRST DOWN CONVERTED TO AN IF SIGNAL CENTERED AND THEN TO NORMAL DATA RANGES.

AND THEN DATA IS TRANSFERRED.

FEATURES OF GI-FI :

High speed of data transfer

Low power consumption

High security

Cost effective

Small size

Quick deployment

Highly portable,highmobility

APPLICATIONS OF GI-FI

1. House hold appliances :

-it makes the wireless home

of the future:

2. Office appliances :

3. Video information transfer:

4. Inter-vehicle communication system:

5. Broadcasting video signal transmission system in sports stadium:

TECHNOLOGY CONSIDERATIONS :

The Gi-Fi integrated transceiver chip is may be launched by starting of few year by NICTA,Australia will be first .

Due to less cost of chip so many companies are forward to launch with lower cost.

The fast data exchange has prompted companies like Intel, LG, Matsushita (Panasonic), NEC, Samsung, SiBEAM, Sony and Toshiba to form WirelessHD, an industry-led effort to define a specification for the next generation consumer electronics products.

20

CONCLUSION :

Within few years, we expect Gi-Fi to be the dominant technology for wireless networking.

which will develop wire less home and office of future.

If the success of Wi-Fi indicate, Gi-Fi potentially can bring wireless broadband to the enterprise in an entirely new way.
