INTRODUCTION To Gi-Fi:INTRODUCTION To Gi-Fi:

Wi-Fi(ieee-802.11b) and WiMax(ieee-802.16e) have captured our attention.

As there is no recent developments which transfer data at faster rate, as Video information transfer taking lot of time.

This leads to introduction of Gi-Fi technology it offers some advantages over Wi-Fi, a similar wireless technology.

It was developed at the National Information And Communication Technology Research Center in MELBOURNE,AUSTRALIA.

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

Disadvantages of Bluetooth & Disadvantages of Bluetooth & Wi-FiWi-FiThe 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.

8

Gi-Fi or Gigabit Wireless is the world's first transceiver .

Gi-Fi will allow 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.

Gigabit wireless: The Gi-Fi integrated wireless transceiver chip, developed at the National ICT Research Centre, Australia.

ArchitectureArchitecture of Gi-Fi 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 .

12

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 transmission 13

Working of Gi-FiWorking of Gi-FiUse of Time Division Duplex for

both transmission and receiving. Conversion of data from IF range to

RF60Ghz rangeThe incoming RF signal is first down

converted to an IF signal centered at 5 GHz and then to normal data ranges.

Then use heterodyne principle for this process to avoid leakages.

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

TECHNOLOGY CONSIDERATIONS :TECHNOLOGY CONSIDERATIONS :

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

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

The potential of mw-WPAN for ultra fast data exchange has prompted companies like Intel, LG, Matsushita (Panasonic), NEC, Samsung, SiBEAM, Sony.

20

Next To Gi-Fi :Next To Gi-Fi : Specifically, WirelessHD has a stated

goal of enabling wireless connectivity for streaming high- definition content between source devices and high-definition displays.

21

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

which will develop wire less home and office of future.

Gi-Fi potentially can bring wireless broadband to

the enterprise in an entirely new way.
