This document discusses next generation wireless technology called Gi-Fi or Gigabit Wireless. Gi-Fi allows wireless transfer of data at speeds up to 5 gigabits per second using the 60GHz frequency band. It was developed by Professor Stan Skafidis of Melbourne University to overcome limitations of existing technologies like Bluetooth and Wi-Fi that have slower speeds and higher power consumption. Gi-Fi uses less power than prior standards and is based on the IEEE 802.15.3c standard. It is expected to be the dominant wireless technology for networking within 5 years and enable wireless broadband and high speed transfer of audio, video and large files.

GI-FI (Gigabit Fidelity) or Giga bit wireless refers to wireless communication at a data rate of more than one billion bits (gigabits) per second. GI-FI offers some advantages over WI-FI, a similar wireless technology. In that it offers faster information rate in GBPS, less power consumption and low cost for short range transmission as compare to current technology. GI-FI consists of a chip which has facility to deliver short-range multi gigabit data transfer in a local environment and compared to other technologies in the market it is ten times faster. GI-FI has the data transfer speed up to 5 GBPS within a short-range of 10 metres. It operates in 60 GHZ frequency band. GI-FI is developed on an integrated wireless transceiver chip. It has both transmitter and receiver, integrated on a single chip which is fabricated using the CMOS (complementary metal oxide semiconductor) process and it also consists of a small antenna. GI-FI allows transferring large videos, audio files, data files etc. within few seconds.

GIFI stands for General Index of Financial Information.
The GIFI is a system that assigns a unique code to a list of items commonly found on income statements, balance sheets, and statements of earnings.
The purpose of the GIFI is to allow the CRA (Canada Revenue Agency) to collect and process financial information more efficiently. For instance, the GIFI lets the CRA validate tax table information electronically rather than manually.

LET'S THINK ABOUT THE PRESENT WIRELESS TECHNOLOGY THAT WE USE TO TRANSFER OUR FILES...ARE WE SATISFIED?? IF YES,IS IT ENOUGH? LET'S STEP INTO THE FUTURE AND LOOK HOW THIS TECHNOLOGY IS GOING TO BENEFIT US
Wi-Fi (IEEE-802.11b) and Wi-Max (IEEE-802.16e) have captured our attention, as there are no recent developments in the above technologies which cannot transfer data and video information at a faster rate and led to the introduction of Gi-fi technology. It offers some advantages over Wi-Fi, a similar wireless technology, that offers faster information rate in Gbps less power consumption and low cost for short range transmissions.
Gi-Fi or Gigabit Wireless is the world’s first transceiver integrated on a single chip in which a small antenna used and both transmitter- receiver are integrated on a single chip which is fabricated using the complementary metal oxide semiconductor (CMOS) process. Because of Gi-Fi transfer of large videos, files can be done within seconds.
Researchers of Melbourne University has come up with a wireless technology which promises high speed short range data transfers with a speed of up to 5Gbps within a radius of 10 meters. The new wireless technology is named as Gi-Fi and operates on the 60GHz frequency band, which is currently mostly unused. The Gi-Fi Chip developed by the Australian researcher’s measures 5mm square and is manufactured using existing complementary metal-oxide-semiconductor (CMOS) technology, the same system that is currently used to print silicon chips.
The best part about this new technology is its cost effectiveness and power consumption, it consumes only 2watts of power for its operation with antenna (1mm) included and the development of Gi-Fi chip costs approximately $10( Rs 380) to manufacture.
In theory this technology would transfers GB’s of your favorite high definition movies in seconds. So Gi-Fi can be considered as a challenger to Bluetooth rather than Wi-Fi and could find applications ranging from new mobile phones to consumer electronics
Gi-Fi or gigabit wireless refers to a wireless communication at a data rate of more than one billion bits (gigabit) per second.
By 2004 some trade press used the term "Gi-Fi" to refer to faster versions of the IEEE 802.11 standards marketed under the trademark Wi-Fi.[1]
In 2008 researchers at the University of Melbourne demonstrated a transceiver integrated on a single integrated circuit (chip) that operated at 60 GHz on the CMOS process.[2] It will allow wireless transfer of audio and video data at up to 5 gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost. Researchers chose the 57–64 GHz unlicensed frequency band since the millimetre-wave range of the spectrum allowed high component on-chip integration as well as the integration of very small high gain arrays. The available 7 GHz of spectrum results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 metres.[2] Some press reports called this "GiFi".[3][4] It was developed by Melbourne University-based laboratories of NICTA (National ICT Australia Limited), Australia’s Information and Communications Technology Research Centre of Excellence.[3]
In 2009, the Wireless Gigabit Alliance was formed. It used the term "WiGig" which avoided trademark confusion

3. 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 will allow 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.
4. Evolution of Gigabit
Technology :
WiMAX
Bluetooth Wi-Fi
Wireless Access
Cables Optical Fiber
6. 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.
7. 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
8. Architecture of Gi-Fi
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 wireless span 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.
9. FEATURES OF GI-FI :
High speed of data transfer
Low power consumption
High security
Cost effective
Small size
Quick deployment
Highly portable,highmobility
11. APPLICATIONS OF Gi-Fi

13. TECHNOLOGY CONSIDERATIONS :
The Gi-Fi integrated transceiver chip is may be launched
by starting of next year by NICTA,Australia will be first .
Due to less cost of chip so many companies are forward to
launch with lower cost. The potential of mw-WPAN for ultra 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.
Specifically, WirelessHD has a stated goal of enabling
wireless connectivity for streaming high- definition content
between source devices and high-definition displays.
14. CONCLUSION :
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.
15. Future Work :
As the range is limited to
shorter distances only we can
expect the broad band with same
speed and low power consumption.
