3. ABSTRACT
 Today’s world is changing drastically. With the changing world the Wireless
technology improvement has become follower in today’s modern life. One
of the biggest improvements made on wireless technology was inventing a
new wireless technology called GI-FI .
 GI-FI stands for gigabit wireless fidelity. It is a wireless transmission
technology; which is ten times faster than other wireless technology.
 Gigabit wireless is the world’s first transceiver integrated on a single chip
that operates at 60 GHz(60*10^9 Hz) frequency band. GIFI has data
transfer speed up to 5Gbps. It is manufactured using CMOS technology.

4. Cont’d.
• The best part of GI-FI technology is its power consumption. It
requires only 2watts of power for its operation with antenna
1mm.
• The evolution of GI-FI came into existence due to the need of
higher data transfer rate and lower power consumption.
• It is expected that Gi-Fi will be the preferred wireless
technology used in home and office of future.

5. INTRODUCTION
 In recent years, the technology has
changed a-lot from wired connection to
wireless connection. Weather it is wired
connection of optical fibers or wireless
connection of Bluetooth and Wi-Fi, the
need for better bandwidth and data
rates never ends. This need led to the
new technology that is more up-to-date
and has standard data exchange rates
named as Gi-Fi.
Gi-Fi or Gigabit Wireless is integrated on a single chip operating at 60GHz. It
uses 5mm Square Chip and 1mm wide antenna and consumes only 2mwatts of
power.

6. Cont’d
 The Gi-Fi solves the problems of
o low data rates
o high power consumption and
o low frequency range of earlier technologies.
 If we compare Bluetooth and Wi-Fi with Gi-Fi, we
would find that where Bluetooth provides
800Kbps with 10mw and Wi-Fi provides 11Mbps
transfer rate with 5mw power consumption, the
Gi-Fi provides 5Gbps transfer rate with just 2mw
of power.

7. ARCHITECTURE OF GI-FI
 The core components of a Gi-Fi system is the
subscriber station which is available to several access
points.
 It supports standard of IEEE 802.15.3C supports
millimeter-wave wireless PAN network. The wireless
PAN network is 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. It supports line of sight
operation.ARCHITECTURE OF GI-FI CHIP

10. FEATURES OF GI-FI
 HIGH SPEED OF
DATA TRANSFER
Speed of Gi-Fi is 5 Gbps, which is 10
times the present data transfer.
LOW POWER
CONSUMPTION
It consumes less than 2mwatt power
for data transfer of gigabits of
information

11. Cont’d.
HIGH SECURITY:
As the IEEE 802.15.3C provides more security, it provides link level security
COST-EFFECTIVE:
The Integrated wireless transceiver chip which transfers data at high speed low
power at low price is $10 which is very less.
QUICK DEPLOYMENT:
Once the antenna and equipment are installed and powered, Gi-Fi is ready for
service. In most cases, deployment of Gi-Fi can be completed in a matter of
minutes, compared with hours for other solutions.

12. Cont’d.
SMALL SIZE:
The chip is just 5mm per side, has a tiny 1mm
antenna and uses the 60GHz “millimeter-
wave‟ spectrum
 OTHER FEATURES:
•High level of frequency re-use communication needs of multiple customers within
a small geographic region can be satisfied.
•It is also highly portable-we can construct where ever we want.
•It deploys line of sight operation having only shorter coverage area.

13. APPLICATIONS OF GI-FI
HOUSE HOLD APPLICATIONS:
Consumers could typically download a high definition movie
in a matter of seconds to music player or smart phone and
having got home, could play it on a home theatre system or
store it on a home server for future viewing again within a
few seconds
OFFICE APPLICATIONS:
As it transfers data at high speeds which made work very
easy, it also provides high quality of information from
internet.
VIDEO INFORMATION
TRANSFER:
By using present technologies video swapping takes
hours of time, whereas by using GI-Fi we can transfer at
a speed of Gbps.

14. Cont’d
INTER-VEHICLE
COMMUNICATION
(IVC) SYSTEM:
Gi-Fi technology uses a wide number of
applications in inter vehicle
communication systems as it enables
the vehicles to stay connected.

15. CONCLUSION
•
 The comparison is performed between Gi-Fi and existing wireless technologies in
this paper shows that the features and benefits of GI-FI make it suitable to
replace the existing wireless technologies. It removes cables that for many years
ruled over the world and provides high speed data transfer rate. Gi-Fi technology
has more number of applications and can be used in many places and devices
such as smart phones, wireless PAN networks etc.
 As now GI-FI has been a developing technology on which still an advanced
research is going on its application.
