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

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

17. Gigabit wireless: The Gi-Fi integrated
wireless transceiver chip, developed at
the National ICT Research Centre,
Australia.

18. APPLICATIONS
 In wireless PAN networks.
 Inter-vehicle communication system.
 Huge data file transfer.
 Office appliances.
 Video information transfer.

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.
