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.

3. INTRODUCTION
 The name itself specifies its gigabit transfer rate.
 It was developed in 2008 at the National Information And Communication
Technology Research Center in MELBOURNE,AUSTRALIA.
 Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a
single chip.
 Operates at 60GHz on the CMOS process.
 Gi-Fi allows 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.
 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:
Bluetooth
Wi-Fi
The disadvantages of existing technologies; i.e.
 Slow rate.
 High power consumption.
 Low range of frequency operation.
All this gave invention to this new technology.

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-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.

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

11. Small size:
5mm preside
1mm antenna at bottom
uses 60Ghz millimeter wave spectrum
Easily Installed
Less cost:
10$ per chip

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.

13. Gi-Fi Access Devices

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.
