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.

The GiFi operates on the 60GHz frequency band.

The GiFi measures 5mm square and it is

manufactured using existing complementary metal

– oxide-semiconductor(CMOS) technology.

It was developed at the National Information And

Communication Technology Research Center in

MELBOURNE,AUSTRALIA.

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.

Why Gi-Fi ?

Comparison of Bluetooth and Wi-Fi with Gi-Fi

WPAN Networks

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

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

What Is 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 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.

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

(including telephones and personal digital

assistants) close to one person

An 802.15.3c based system often uses small

antenna at the subscriber station. The antenna is

mounted on the roof. 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 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 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

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 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 and Toshiba to form Wireless HD, an industry-led

effort to define a specification for the next generation consumer

electronics products.

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.

CONCLUSION :

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.

If the success of Wi-Fi and the imminent

wide usage of WiMAX is any indication, Gi-Fi

potentially can bring wireless broadband to the

enterprise in an entirely new way.
