Gi-Fi or gigabit wireless refers to a wireless communication at a data rate of more than one billion bits (gigabit) per second. By 2004 some trade press used the term "Gi-Fi" to refer to faster versions of the IEEE 802.11 standards marketed under the trademark Wi-Fi.[1] In 2008 researchers at the University of Melbourne demonstrated a transceiver integrated on a single integrated circuit (chip) that operated at 60 GHz on the CMOS process.[2] It will allow wireless transfer of audio and video data at up to 5 gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost. Researchers chose the 57–64 GHz unlicensed frequency band since the millimetre-wave range of the spectrum allowed high component on-chip integration as well as the integration of very small high gain arrays. The available 7 GHz of spectrum results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 metres.[2] Some press reports called this "GiFi".[3][4] It was developed by Melbourne University-based laboratories of NICTA (National ICT Australia Limited), Australia’s Information and Communications Technology Research Centre of Excellence.[3] In 2009, the Wireless Gigabit Alliance was formed. It used the term "WiGig" which avoided trademark confusion

INTRODUCTION To Gi-Fi
 For many years cables ruled the world, but installation of cable
caused a greater difficulty and lead to wireless access.
Foremost of this is Bluetooth then Wi-Fi followed it. But the mans
continuous quest for even better technology led to the introduction of
new ,more up-to-date standard for data exchange rate i.e. Gi-Fi.
Wi-Fi and WiMax 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.

5. Why Gi-Fi ?
 The reason for pushing into Gi-Fi
technology is because of
 Slow rate
 Low range of frequency operations

7. 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

8. 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.

9. Architecture of Gi-Fi :
 The core components of a GI-FI system is the
subscriber station which available to several access points.
The wireless span is computer network use for
communication among computer devices (including
telephones and personal digital assistants) close to one
person
 Ancient system often uses small antenna at the
subscriber station. The antenna is mounted on the roof. It
supports line of sight operation.

 Use of Time Division Duplex for both transmission and
receiving.
 Conversion of data from IF range to RF60Ghz range.
 Then use heterodyne principle for this process to avoid
leakages and then data is transferred.

11. FEATURES OF GI-FI :
 High speed of data transfer
 Low power consumption
 High security
 Small size
 Quick deployment
 Highly portable,highmobility

 High data rate
 Low cost
 Ease of development
 Enabling the future of information
management
BENEFITS OF GI-FI

13. APPLICATIONS OF GI-FI
 House hold appliances
 Office appliances
 Video information transfer
 Inter vehicle communication system
 Broad casting video signal transmission system
in sports stadium

14. 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 WirelessHD, an industry-led
effort to define a specification for the next generation consumer
electronics products.

15. 15
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.

16. 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.
