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. (Gigabit
Fidelity). 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 frequency band. GIFI has data
transfer speed up to 5Gbps. It is manufactured using CMOS technology. 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. In this paper, the comparison is performed
between Gi-Fi and some of existing technologies with very high speed large files transfers
within seconds. It is expected that Gi-Fi will be the preferred wireless technology used in
home and office of future.

CHAPTER 1
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. As still we
used Wi-Fi for better data exchange rates and ranges having good network coverage but the
needs always look-up for better. 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. About
its transfer rates, it can transfer the audio and video at the rate of 5Gbps at one-ninth of cost
that is approx. 10 times to that of current transfer rates. It uses 5mm Square Chip and 1mm
wide antenna and consumes only 2mwatts of power.
The Gi-Fi solves the problems of low data rates, high power consumption and low
frequency range of earlier technologies as Bluetooth and Wi-Fi. As it has integrated trans-
receiver (Transmitter and Receiver) on single chip and small antenna, it can provide better
transfer rates with low power consumption.
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.

CHAPTER 2
LITERATURE SURVEY
1) World survey: Australia is the pioneer in development of GI-FI technology.
Melbourne University researchers have invented 5Gbps data transfer rates on a
wireless chip. This is a very fast than our current Wi-Fi speeds. The world's first GI-
FI wireless network chip developed at Australia's peak federal technology incubator
has entered its commercialization phase.
The NICTA (National ICT Australia Limited) GI-FI research team successfully
invented 60GHz transmission technology. Ross and John in 2007 proposed a model
that MIMO increased capacity 10 times or more and improves radiating energy
efficiency of order of 100 times.
2) India survey: S. Dheeraj and S. Gopichand in 2002 proposed a model in which they
invented a technology which has gain flexibility of infrastructure, reduce capacity
expenditure, gain advantages over competitors and to solve business problem.
Goutam S Shetty in 2006 proposed that wireless dual band router and wireless dual
band USB adapter are based on upcoming WI-FI technology, which is new wireless
technology in 802.11ac family.
Sachin Abhyankar in 2009 proposed a model which show WI-FI which resolve all
problems which occur in Bluetooth, limitation of data transfer rate and range.
Ramiaz in 2011proposed that radio link can operate in indoor environment with
considerably small power consumption.

CHAPTER 3
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. The
antenna is mounted on the roof. It supports line of sight operation.
FIGURE 3.1: COMPONENTS OF GI-FI CHIP
The chip uses the 60GHz range, has a range of 10meters, is just 5mm in size, and uses
an antenna measuring 1mm wise Power consumption is also minimal, at just <2mwatts.
The chip was created by a team of 27 taken from the Gigabit Wireless Project and
headed up by Stan Skafidas. The new chip has been the culmination of 10 years development
and collaborations with well-known technology companies.

CHAPTER 4
EVOLUTION OF GI-FI
Communication or data transfer technology is mainly classified into two groups
which are 1) Wired technology and 2) Wireless technology.
Initially we come in contact with wired technology but there are lots of difficulties
arrived during installing of wired technology hence wireless technology was invented. This
wireless technology leads to GI-FI technology. Below diagram will give the network
evolution.
FIGURE 4.1: EVOLUTION OF GI-FI

4.1 CABLES
Being the oldest method of data transmission, trained manpower to repair and
service this media of communications are easily available.
Its disadvantage is that it can easily pick up noise signals which results in higher error
rates when the line length exceeds 100 meters. Being thin in size, it is likely to break easily.
4.2 OPTICAL FIBRES
Fibre optic cables have a much greater bandwidth than metal cables. Fiber optic
cables are much thinner and lighter than metal wires. They also occupy less space with
cables of the same information capacity.
Its disadvantage is that Fibers can be broken or have transmission loses when
wrapped around curves of only a few centimeters radius. Optical fibers require more
protection around the cable compared to copper.
4.3 WIRELESS ACCESS
The computer networks that are wireless means the computers are not connected with
wires. These networks help reduce cost of cables which are otherwise used to connect the
nodes. They make use of radio communication where radio waves are used to connect
devices like laptops to internet.
Its disadvantage is that the speed and the viability of the wireless signals drop as more
and more users use the same frequency. Moreover its original throughput is three times less
than it claims to deliver. Wireless technology is available in only three major channels
ranging from 2.5 GHz, 11 and 1.6 GHz, Which is much lower than the wired network. They
are 50 times slower than the wired network technologies.

4.4 BLUETOOTH
Bluetooth is now really popular and keeps getting more popular as time passes by. It
is now widely used across countries and almost by everyone. Companies are taking the
benefit by using this in their new and future products to make life much easier for everyone
Its disadvantage is that throughout all devices, when using Bluetooth internet, the
connection can sometimes run very slow so Bluetooth internet is not highly suggested for all
cases.
4.5 WI-FI
Wi-Fi network is particularly useful in cases where the wiring is not possible or even
unacceptable. For example, it is often used in the halls of conferences and international
exhibitions. It is ideal for buildings that are considered architectural monuments of history, as
it excludes the wiring cables.
Wi-Fi networks are widely used to connect a variety of devices, not only between
themselves but also to the Internet. And almost all modern laptops, tablets, and
some mobile phones have this feature. It is very convenient and allows you to connect to the
internet almost anywhere, not just where the cables are laid.
Today, you can access the network, for example, being in the park for a walk across
the street or in an airport lounge
Its disadvantage is its slower speed in busy network or to transfer read time data. In
real-world applications, wireless networking is significantly slower than wired networking
when transferring files over a local area network.
The problem becomes even more acute if you have a busy network or if your signal
strength is weaker than optimal.

4.6 WIMAX
WiMAX infrastructure is very easy and flexible therefore it provides maximum
reliability of network and consent to actual access to end users. The Wimax network
providing much higher speed and very long range as compared to Wi-Fi Technology.
The WiMAX network has lack of quality service because there are hundreds of
people trying to get access at the same tower so due to heavy traffic it is very hard to
maintain high quality.
The most disadvantage of WiMAX is its installation and operational cost. Due to
heavy structure, tower, antennas etc. makes the WiMAX network collectively high cost
network.
The quality of services decreases in rainy season because the weather condition could
interrupt the signal which may cause of bad signal and broadcasting may be stop or
interrupted.
The data rate of WiMAX as compared to other network such as fiber optics, satellite,
cables etc are very slow.
4.7 GI-FI
The new gigabit wireless system provides Multi-gigabit wireless technology that
removes the need for cables between consumer electronic devices and is More than 100 times
faster than current short-range wireless technologies such as Bluetooth and Wi-Fi.
This technology with high level of frequency re-use can satisfy the communication
needs of multiple customers within a small geographic region. The sheer density of the signal
would allow a chip to send as much as 5 gigabits per second. While the spectrum would limit
the device to the same 33-foot range as Bluetooth or UWB, it could theoretically transfer an
HD movie to a cell phone in seconds.
There are lots of reasons to use GI-FI instead of other wireless technology, these are
as given below:

a) In GI-FI technology chip is used which is work on 60GHz frequency and of speed of
5Gbps which is much greater than recently used wireless technology such as WI-FI
and Bluetooth.
b) In GIFI mixing and signal filtering is used which would keep the signal strong versus
the large range, but in slower speed as WIFI
c) The GIFI uses the short-range wireless technology would potentially be a competitor
or more than likely a replacement for WIFI, and things like Bluetooth might want to
look out as well.
d) GIFI technology consume less power as compared to WIFI and Bluetooth
e) The reason for pushing into GIFI technology is because of slow rate, high power
consumption, low range of frequency operations of earlier technologies i.e. Bluetooth
and Wi-Fi.

CHAPTER 6
FEATURES OF GI-FI
6.1 HIGH SPEED OF DATA TRANSFER
The main invention of Gi-Fi is to provide higher bit rate .As the name itself indicates
data transfer rate is in Giga bits per second. Speed of Gi-Fi is 5 Gbps, which is 10 times the
present data transfer. Because of this high speed data transfer, we can swap large video,
audio, data files within seconds. Because of wider availability of continuous 7 GHz
spectrum, it results in high data rates.
FIGURE 6.1.1: SPEED RATE OF GI-FI TECHNOLOGY

6.2 LOW POWER CONSUMPTION
As the large amount of information transfer it utilizes milli-watts of power only.
It consumes less than 2mwatt power for data transfer of gigabits of information, where as in
present technologies it takes 10mwatt power, which is very high.
FIGURE 6.2.1: POWER CONSUMPTION OF GI-FI TECHNOLOGY
6.3 HIGH SECURITY
As the IEEE 802.15.3C provides more security, it provides link level and service
level security, where these features are optional. Point-to-point wireless systems operating at
60 GHz have been used for many years by the intelligence community for high security
communications and by the military for satellite-to satellite communications. The combined
effects of O2 absorption and narrow beam spread result in high security and low
interference.

6.4 COST-EFFECTIVE
Gi-Fi is based on an open, international standard. Mass adsoption of the standard,
and the use of low-cost, mass produced chipsets, will drive costs down dramatically, and the
resultant Integrated wireless transceiver chip which transfers data at high speed low power at
low price is $10 which is very less As compare to present systems .As we go on
development the price will be decreased.
6.5 SMALL SIZE
The chip is just 5mm per side, has a tiny 1mm antenna and uses the 60GHz
“millimeter-wave‟ spectrum.
FIGURE 6.5.1 : SIZE OF GI-FI CHIP

6.6 QUICK DEPLOYMENT
Compared with the deployment of wired solutions, Wi-MAX requires little or no
external plant construction. For example,excavation to support the trenching of cables is not
required. Operators that have obtained licenses to use one of the licensed Bands, or that plan
to use one of the unlicensed bands; do not need to submit further applications to the
Government. 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.
6.7 OTHER FEATURES
 High level of frequency re-use enabled –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.
 It has more flexible architecture.

CHAPTER 7
APPLICATIONS OF GI-FI
There are many usage scenarios that can be addressed by Gi-Fi. The following are
some mobility usage applications of Gi-Fi.
7.1 HOUSE HOLD APPLIANCES
Consumers could typically download a high definition movie from a kiosk 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.
High speed internet access, streaming content download (video on demand, HDTV,
hometheatre, etc.), real time streaming and wireless data bus forcable replacement. It makes
the wireless home and office of the future.
FIGURE 7.1.1: HOUSE HOLD APPLIANCES.

7.2 OFFICE APPLICATIONS
As it transfers data at high speeds which made work very easy, it also provides high
quality of information from internet.
FIGURE 7.2.1: OFFICE APPLICATIONS (a)
FIGURE 7.2.1: OFFICE APPLICATIONS (b)

7.3 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. Data transfer rate is same for transfer of
information from a PC to a cell or a cell to a PC. It can enable wireless monitors. It supports
the efficient transfer of data from digital camcorders, wireless printing of digital pictures
from a camera without the need for an intervening personal computer and the transfer of files
among cell phone handsets and other handheld devices like personal digital audio and video
players.
FIGURE 7.3.1: VIDEO TRANSFER USING GI-FI
7.4 INTER-VEHICLE COMMUNICATION SYSTEM
Gi-Fi technology uses a wide number of applications in inter vehicle communication
systems as it enables the vehicles to stay connected and go and it also offers better speed of
vehicles in advent of communication system. The data exchange between vehicles is made
possible by ad-hoc networks.

CHAPTER 8
CONCLUSION
Gi-Fi has given and it is conspicuous that more research should be done in the field of
this new wireless technology and its applications. The Bluetooth which covers 9-10mts range
and WI-FI followed 91 meters . No doubt introduction of WI-FI wireless network has
proved a revolutionary solution to bluetooth problem.
The standard original limitations for data exchange rate and range, number of
chances, high cost of infrastructure have not yet made possible for WI-FI to become a
power network. Despite the advantages of present technologies, led to the introduction of
new, more up-to-date technology for data exchange that is GI-FI.
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. Iit 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 ,
media access control and mm-Wave video-signals transmission systems.
As now GI-FI has been a developing technology on which still an advanced research
is going on its application.
