4. A.CABLES
A cable is two or more wires running side by side and
bonded, twisted, or braided together to form a single
assembly. The term originally referred to a nautical line
of specific length where multiple ropes, each laid
clockwise, are then laid together anti-clockwise and
shackled to produce a strong thick line, resistant to water
absorption, that was used to anchor large ships.
B.OPTICAL FIBRE
An optical fiber cable is a cable containing one or
more optical fibers that are used to carry light. The optical
fiber elements are typically individually coated with
plastic layers and contained in a protective tube suitable
for the environment where the cable will be deployed.
5. C. WIRELESS ACCESS:
In computer networking, a wireless Access
Point (AP) is a device that allows wireless
devices to connect to a wired network using Wi-
Fi, or related standards. The AP usually connects
to a router (via a wired network) as a standalone
device, but it can also be an integral component
of the router itself.
D.BLUETOOTH
Bluetooth is a wireless technology standard for
exchanging data over short distances (using
short-wavelength UHF radio waves in
the ISM band from 2.4 to 2.485 GHz) from fixed
and mobile devices, and building personal area
networks (PANs).
6. E.WI-FI
Wi-Fi is based on the IEEE 802.11wireless
local area network (WLAN) specification.
Actually it was designed tube used indoors at
close range for example home user and office
environment. The main goal of Wi-Fi technology
is to provide service for mobile computing
device like laptop
Many devices can use Wi-Fi, e.g., personal
computers, video-game consoles, smart phones,
some digital cameras, tablet computers and
digital audio players. These can connect to a
network resource such as the Internet via a
wireless network access point. Such an access
point (or hotspot) has a range of about 20 meters
(66 feet) indoors and a greater range outdoors.
7. F.WI-MAX
WIMAX stands for Worldwide
interoperability for Microwave access.
This technology is capable of transmitting
data at a rate of 1Gbps.
GIFI is the technology that uses
extremely high frequency of 60GHz for
the transmission of data.
The process of mixing and signal
filtering enhances the strength of the
signal, with minimal losses in the
medium.
Just like Bluetooth, this technology uses
short-range wireless communication. This
feature competes with the contemporary
wireless communication technologies.

10. GIFI STANDS FOR GIGABIT WIRELESS.
GIFI is a wireless transmission system which is ten times faster than other
technology and its chip delivers short-range multi gigabit data transfer in a
local environment. GIFI is a wireless technology which promises high speed
short range data transfers with speeds of up to 5Gbps within a range of 10
meters.
The GIFI operates on the 60GHz frequency band. This frequency band is
currently mostly unused. It is manufactured using (CMOS) technology.
11. G. GIFI-TECHNOLOGY
GIFI or Gigabit Wireless is the world’s first transceiver integrated at 60GHz a
wireless transmission system which is ten times faster than WI-FI.
The need of data transmission is increasing drastically day-by-day. The
technologies are accelerating with rocket pace. Data transmission was through
optical fibers in the first generation.
In the latest generation Bluetooth, WIFI WIMAX have become the
technologies of wireless communication. But because of the limitations of the
technologies, a need of alternative technology has always prevailed.
In connection with this, the researchers of Melbourne University are carrying
out their researches and coined a new technology in the name GIFI.
12. INTEGRATED TRANSCEIVER
GIFI or Gigabit Wireless is the
world’s first transceiver
integrated at 60GHz a wireless
transmission system which is ten
times faster than WI-FI and its
chip delivers short range multi
gigabit data transfer in an indoor
environment it will allow
wireless transfer of audio and
video up to 5 gigabits per second
low power consumption, usually
within the range of 10 meters the
size of the chip is (5*5) mm and
can be placed in different devices
such as mobile phones.
13. HIGH SPEED DATA TRANSMISSION THROUGH GIFI.
WHY GIFI IS THE BEST TECHNOLOGY
When telling people to migrate from Wi-Fi or
WI-Max to GIFI, the question you usually hear is
why. There are actually a few good reasons to
move to the new technology. The process of GIFI
would use a chip that transmits at an extremely
high60GHz frequency versus the 5GHzused for
the fastest forms of Wi-Fi .
Mixing and signal filtering used in GIFI
technology would keep the signal strong versus
the longer ranged but slower and more drop
prone Wi-Fi option of today. 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.
14. The core components of a GI-FI system is the subscriber station
which available to several access points .
It supports standard of IEEE 802.15.3C
The Wirelessspan 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.
17. ADVANTAGES OF GI-FI:
The valuable advantages of the GIFI technology can be abbreviated as
follows:
• Profitable Chip
The chip in GIFI would likely cost about $10 or less to build a small design
would allow cell phones and other small devices to add the technology
without significantly drive up the price, according to the company. As go on
development the price will be decreased.
• Small in size
The size of the GIFI chip is 5×5millimetre and can be placed indifferent
devices such as mobile phones. The chip has a tiny 1mmantenna and uses the
60GHz‘millimetre-wave’ spectrum.
18. Faster Data Transmission
GIFI is a wireless transmission system which is ten times faster than Wi-Fi
and it’s chip delivers short-range multi-gigabit data transfer in an indoor
environment. It will allow wireless transfer of audio and video data up to 5
gigabits per second.
Low Power Consumption
As the large amount of information transfer it utilizes milli-watts of power
only. Power consumption of the present technologies such as Wi-Fi and
Bluetooth are 5mili watts and 10mili watts but chip of GIFI uses a tiny one-millimeter-
wide antenna and it has less than 2milli watts of power
consumption that in compare to the current technologies is very less.

21. FUTURE SCOPE
Within five years, we expect GI-FI to be the dominant technology for wireless
networking. By that time it will be fully mobile, as well as providing low- cost, high
broadband access, with very high speed large files swapped with in seconds 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. A completely integrated single chip transceiver has been
fabricated, tested and demonstrated in Gi-Fi chip and a transceiver with integrated phased
array antenna on 65nm CMOS technology has been sent for fabrication. Gi-Fi technology
demonstrates the world’s first fully integrated transceiver on CMOS technology operating at
60 GHz and provides new technique for integrating antennas on CMOS. Demonstrations of
Gi-Fi technology can be arranged showing the huge potential it has to change the way
consumers use their in-home electronic devices. The Gi-Fi team is looking for partners
interested in commercializing its 60GHz chips and with growing consumer adoption of High-
Definition (HD) television, low cost chip and other interesting features of this new technology
it can be predicted that the anticipated worldwide market for this technology is vast.
