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 lineof 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.

OPTICAL

FIBRE

An optical fiber cable is a cable containing one ormore 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.

WIRELESS

ACCESS

:

In computer networki

ng, 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.

BLUETOOTH

Bluetooth is a wireless technology standard for

exchanging data over short distances (usingshort-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).

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 awireless network access point. Such an access

point (or hotspot) has a range of about 20 meters

(66 feet) indoors and a greater range outdoors.

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.

COMPARISON OF WIFI AND BLUETOOTH WITH GIFI

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 speedshort 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.

G. GIFI-TECHNOLOGY

GIFI or Gigabit Wireless is the worldsfirst 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.

GIFI or Gigabit Wireless is theworlds 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 thesize of the chip is (5*5) mm and

can be placed in different devices

such as mobile phones.

INTEGRATED TRANSCEIVER

14/22

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.

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 ondevelopment the price will be decreased.

Small in size

The size of the GIFI chip is 55millimetre and can be placed indifferent

devices such as mobile phones. The chip has a tiny 1mmantenna and uses the60GHzmillimetre-wave spectrum.

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 worlds 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.
