Gi-Fi is a new wireless technology that allows data transfer speeds up to 5 gigabits per second within a 10 meter range, which is 10 times faster than current wireless speeds. It was developed in Australia and operates at 60GHz on a single-chip transceiver. Gi-Fi is expected to become the dominant wireless technology in the near future, bringing wireless broadband to homes and offices through uses like connecting appliances and transferring video/audio files quickly. It has advantages over existing wireless technologies like Bluetooth and Wi-Fi through higher speeds, lower power consumption, and small chip size.

7. 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.

9. 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

11. 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.

13. 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.
An 802.15.3c based system often uses small antenna at the
subscriber station. It supports line of sight operation. 13

14. FUNDAMENTAL TECHNOLOGIES IN 802.15.3C :
It transmits multiple signals simultaneously across
the wireless transmission paths to avoid
interference.
It uses ultra wide band.
Which consists of :
1. High bit rate
2. High security
3. Faster data transmission

15. 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 AND THEN TO NORMAL DATA RANGES.
AND THEN DATA IS TRANSFERRED.

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

18. 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:

20. TECHNOLOGY CONSIDERATIONS :
 The Gi-Fi integrated transceiver chip is may be launched by
starting of few year by NICTA,Australia will be first .
 Due to less cost of chip so many companies are forward to launch
with lower cost.
The 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.

21. CONCLUSION :
Within few 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 indicate, Gi-Fi
potentially can bring wireless broadband to
the enterprise in an entirely new way.
