3. INTRODUCTION TO GI-FI
Gigabit Fidelity or Gigabit Wireless
World's first transceiver integrated on a single chip
Fabricated using CMOS (Complementary Metal
Oxide Semiconductor) process
Wireless transfer of audio and video data up to 5
gigabits per second

4. INTRODUCTION TO GI-FI
Developed at the National Information And
Communication Technology Research Center in
MELBOURNE, AUSTRALIA
Gi-Fi is ten times the current maximum wireless
transfer rate usually within a range of 10 meters

7. WHY GI-FI
The reason for putting into GI-FI technology is
because of
Slow rate
High power consumption
Low range of frequency operation of earlier
technologies ie, Bluetooth and Wi -Fi

10. ARCHITECTURE OF GI - FI
The core component of GI – FI is the
subscriber station.
It supports standard of IEEE 802.15.3C.
An 802.15.3C based system uses small antenna
at subscriber station.
It supports line of sight operation.

11. WORKING PRINCIPLE
Time division duplex for both transmission and
reception
Transmission
Data files up converted from IF to RF at 60 GHz range
Conversion using two mixers
Fed to a power amplifier
Fed to millimeter wave antenna
1116-04-2017 GOPIKA S S
13. WORKING PRINCIPLE
Reception
RF signal down converted to an IF signal centred at
5 GHz
Converted to normal data ranges using heterodyne
principles to avoid leakages.
Availability of 7 GHz spectrum
Transfer within seconds

15. WHY 60 GHz?
Millimetre wave antenna operates at 60 GHz
Unique benefits like immunity to co-channel
interference, high security and frequency reuse
High oxygen absorption at 60 GHz
This absorption attenuates 60 GHz signals over
distance , so that signals cannot travel far beyond their
intended recipient

16. FEATURES OF GI - FI
High speed of data transfer - 5 gigabits per second
Low power consumption - 2 watt power
High security
Cost effective – 10$ per chip
Small size - 5mm per side
Easily Installed
Highly portable
Quick deployment
Flexible architecture

19. TECHNOLOGY
CONSIDERATIONS
Due to less cost of chip so many companies are looking
forward to launch with lower cost.
The Gi - Fi integrated transceiver chip is may be
available in by starting of next year by NICTA,
Australia will be first .
May become one of the important component in next
generation consumer electronic products

20. CONCLUSION
Within five years, we expect Gi-Fi to be
the dominant technology for wireless
networking.
Gi-Fi can bring wireless broadband to
the enterprise in an entirely new way.
