4. INTRODUCTION OF GI-FI TECHNOLOGY
• Gi-Fi or GiGabite wireless is the world’s first Transciever integrated on a single chip.
• It operates at 60GHz on the CMOS process.
• Gi-Fi allows wireless transfer of audio and video data up to 5 gigabites per second (Gbps).
• GiFi is a wireless transmission system which is ten times faster than Wi-Fi .
• Gi-Fi is a ten times current maximum wireless transfer rate usually within a range of 10meters.
• It was developed at the National Information And Communication Technology Research
Center in MELBOURNE,AUSTRALIA.

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.
Blutooth & Wi-Fi .

7. MAN BEHIND GI-FI:-
Professor Stan Skafidis of Melbourne University.

8. DISADVANTAGES OF BLUTOOTH & WI-FI
• The bit rate of Blutooth is 800kbps and Wi-Fi
has maximum of 11Mbps.
• Both are having power consumption 5mw and
10mw.
• The lower frequency of operation 2.4GHz. For
Transferring large amount of Video,
audio,data files take hours of time.
So,to have higher data
transfer rate at lower power
consumption We move onto
Gi-Fi Technology.

10. ARCHITECTURE OF GI-FI
• The core component of a Gi-Fi system is the subscriber
station.
• It supports standard of IEEE 802.15.3C Wireless Pan.
• An 802.15.3C based system often uses small antenna at the
subscriber station.
• The antenna mounted on the roof.
• It supports line of sight operation.

11. WORKING OF GI-FI
• Use of “TIME DIVISION DUPLEX “ For both transmission and
receiving.
• Conversion of data from IF to RF 60GHz range.
• The incoming RF signal is first down Converted to an IF signal centered at
5GHz and then to normal data ranges.
• Then use HETERODYNE principle for this process to avoid leakages.
• And then data is transferred.
................................

12. GI-FI ACCESS DEVICE
• GI-FI technology has much number of applications and can be
used in many places and devices such as smart phones,
wireless pan networks, media access control and mm- Wave
video-signals transmission systems. This chip could also
replace HDMI cables and develop wireless home and office of
future.

13. FEATURES OF GI-FI TECHNOLOGY
1. High Speed of data transfer
2. Low power consumption
3. High security
4. Cost effective (Low cost)
5. Small size
6. High portable

14. APPLICATION OF GI-FI TECHNOLOGY
1. House 🏠 hold appliances
=> It makes wireless Home and office of the future.
2. Office appliances
=> As it transfer data at high speeds so that ,made work very easy.
3. Video information transfer
. => We can transfer at speed of Gbps.
4. Inter vehicle Communications system.
=>

15. TECHNOLOGY CONSIDERATION
• The Gi-Fi integrated Tranciever chip may be launched by starting of the
Next year by NICTA, Australia will be first.
• Due to less Cost of chip so many companies are looking forward to launch
lower cost.
• Specifically, Wireless HD has a stated goal of enabling wireless
connectivity gor streaming high definition Content between source
devices and high-definition displays.

16. .............CONCLUSION............
• Within next few years, Gi-Fi to be the dominant technology for
wireless networking.
• Which will develop wireless Home 🏠 and office of future.
• If the success of Wi-Fi and Eminent wide usage of WIMAX is any
indication, Gi-Fi potentially can bring wireless broadband to the
enterprise in an entirely new way.
