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.

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
1. House hold appliances :
it makes the wireless home
and office of the future
2. Office appliances :
3. Video information transfer:

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.
