Gi-Fi is a next generation wireless technology that was developed in 2008 to allow for wireless transfer of audio and video data at speeds up to 5 gigabits per second, which is 10 times faster than current wireless technologies. It operates using 60GHz frequency bands and integrated circuits on a single chip. Gi-Fi aims to address limitations of existing technologies like Bluetooth and Wi-Fi that have slower speeds and higher power consumption. It uses techniques like beamforming to avoid interference and supports the IEEE 802.15.3c standard. Potential applications include wireless connectivity for household appliances, offices, and high-speed file transfers.
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 (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.

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

Gi-Fi is ten times the current maximum wireless transfer rate usually within
a range of 10 meters.
It refers to wireless communication at a data rate of more than 1 billion per
second.
5. Why Gi-Fi ?
The common Wireless technologies currently used
are:

Comparison between Bluetooth, Wi-Fi and Gi-Fi
7. Disadvantages of Bluetooth & Wi-Fi
The bit rates of Bluetooth is 800 Kbps and Wi-
Fi has maximum of 11 Mbps
Both are having power consumptions 5mw
and 10mw
The lower frequency of operation 2.4GHz.
so, to have higher data transfer rate at lower
power consumption we move onto Gi-Fi
technology.
8. FUNDAMENTAL TECHNOLOGIES IN 802.15.3C
8
It transmits multiple signals
simultaneously across the
wireless transmission paths
within separate frequencies to
avoid interference.
It uses ultra wide band
Which consists of :
1. High bit rate
2. High security
3. Faster data transmission
9. Architecture of
Gi-FiThe 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.
10. ATTRACTIVE FEATURES
High bit rate:
5 gigabits persecond,
easily swapping video,audio,data files
Power consumption:
2 mill-watt power compared to 10 watt power
Security:
uses IEEE 802.15.3c standards
12. Applications of Gi-Fi
12
1. Household appliances :
It makes the wireless home and office of
the future.
2. Office appliances :
As it transfers data at high speeds
that made work very easy .
3. Video information transfer:
We can transfer at a speed of gbps.
14. Here we would use a time division duplex for
both transmission and receiving.
The data files are converted from IF range to RF
60Ghz range by using 2 mixers.
We will feed this to a power amplifier, which
feeds millimeter-wave antenna.
The incoming RF signal is first converted to an
IF signal centered at 5 GHz ,and then to normal
data ranges, here we will use heterodyne
construction for this process to avoid leakages
due to direct conversion.
Due to availability of 7 GHz spectrum the total
data will be transferred within seconds.
15. TECHNOLOGY
CONSIDERATIONS
The Gi-Fi integrated transceiver chip is may be
launched by starting of next year by
NICTA,Australia.
Due to less cost of chip so many companies are
forward to launch with lower cost.
mw-WPAN for ultra fast data exchange has
prompted companies like Intel, LG, Matsushita
(Panasonic), NEC, Samsung, Si-BEAM, Sony
and Toshiba.
17. 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.
