For many years cables ruled the world, but installation of this causes great difficulty.

Mans continuous quest for even better technology led to the Introduction of GI-FI.

As there is no recent development which transfers the data faster. “This leads to introduction of GI-FI technology .“

Developed at “National Information And Communication Technology Research Center” - MELBOURNE,AUSTRALIA.

INTRODUCTION TO GI-FI

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 .

Comparison of Bluetooth and Wi-Fi with Gi-Fi

characteristics

Bluetooth Wi-Fi Gi-Fi

Frequency 24GHz 24GHz 60GHz

Range 10 meter 100meters 10meters

Primary application WPAN cable replacement WLAN Ethernet Embedded in devices

Data transfer rate 800 Kbps 11Mbps 5Gigabps

Power consumption 5mw 10mw 2mw

Primary devices Mobile phones,PDAs,consumer electronics,office and industrial devices

Notebooks, desktop computer

Fax , Printer , Cellular phones

Primary uses Travelling employees,electronics consumers,office ad industrial workers

corporate users Wireless Home & office appliances ,etc.

Usage location Anywhere atleast two bluetooth device exist-ideal for roaming outside buildings

Within range of WLAN infrastructure,usually inside a buildings

WPAN Networks

Specification Bluetooth S&G IEEE 802.11b,WBCA IEEE 802.15.3C

7

Disadvantages of Bluetooth & Wi-FiBit rate : Bluetooth-800kbps Wi-Fi -11mbpsPower consumption :

Bluetooth- 5mw Wi-Fi-10mw

Lower frequency-2.4GHz.

So, to have higher data transfer rate at lower power consumption we switch onto GI-FI technology

6

What Is GI-FI ?What Is GI-FI ?World's First transceiver integrated on a single chip CMOS.

Operates - 60GHz.

Transfer of Audio & Video data - 5Gigabs.

Ten times faster then the current wireless transfer rate.

Technologies used- MIMO (Multiple Input Multiple Output) SOP (System-On-a-Package)

7

ARCHITECTURE OF GI-FI:

8

Core component is the Subscriber station available to several access points .

Standard- IEEE 802.15.3C

This system often uses Small antenna at the subscriber station.

This antenna supports Line of sight operation.

Working of Gi-Fi

Use of Time Division Duplex for both transmission and receiving.

TRANSMITTING : Conversion of data from IF range to RF 60Ghz range.

RECEIVING : The incoming RF signal is converted to an IF signal and then to normal data ranges.

Uses Heterodyne principle. Data is transferred.

9

FEATURES OF GI-FI :

High speed of data transfer

Low power consumption

High security

Cost effective

Small size

Quick deployment

Highly portable

High-mobility.

GI-FI ACCESS DEVICES:

APPLICATIONS OF GI-FI

2. Office appliances .

3. Video information transfer.

13

1. House hold appliances :

14

4. Inter-vehicle communication systems.

5. Broadcasting video signal transmission system in sports st system in sports stadium.

NEXT TO GI-FI

Specifically, Wireless-HD has a stated goal of enabling wireless connectivity for streaming high- definition content between source devices and high-definition displays.

15

CONCLUSION :

Within five years, we expect GI-FI to be the dominant technology for wireless networking. Develops wire-less home and office of future.GI-FI potentially can bring wireless broadband to the enterprise in an entirely new way.
