3. INTRODUCTION
 Gi-Fi or Gigabit Wireless is the world's first transceiver
integrated broadband chip based on CMOS process. It can
be easily embedded into devices that operates at 60GHz.
 Gi-Fi allows wireless transfer of audio and video data upto
5 gigabits per second (i.e.) more than 5 billion bits per
second.
 Gi-Fi facilitates wireless data transfer in an indoor
environment with a span of 10 meters.

EVOLUTION

5. CURRENT TECHNOLOGIES
The existing technologies are:
 BLUETOOTH
 WI-FI(Wireless Fidelity)
The above mentioned existing technologies stay behind from
Gi-Fi in terms of:
 Low range of frequency operation
 Slow speed of data transfer
 High power consumption

6. WHY GI-FI?
 Gi-Fi uses the frequency range of 57-64Ghz(7Ghz).
 This is because of high oxygen absorption at 60 Ghz.
 This absorption attenuates signals over distance so that the
signal cannot travel beyond the intended receiver.
 Using Gi-Fi, large amount of files can be swapped within
seconds.

9. ARCHITECTURE OF GI-FI
 A Gi-Fi system works based on a subscriber station with a
small antenna.
 This subscriber system is available to several access points
surrounding it.
 It satisfies the standards of IEEE 802.15.3C (i.e.)Wireless
PAN.
 It supports line of sight operation.

10. WORKING OF GI-FI
 Gi-Fi system works on the basis of TDD(Time Division
Duplex) for both transmission and reception of data.
 Gi-Fi uses Radio waves for data transfer.
 The incoming radio wave frequency is converted into IF and
the data is thus transferred.
 It uses heterodyne principle to avoid leakage of data.

11. ADVANTAGES
 Excellent immunity to co-channel interference
 High security
 Frequency re-use
 High speed data transfer
 Cost effective
 High portability due to smaller size
 Numerous users within a small geographic area

Gi-Fi Technlogy stands ahead of existing systems like
BlueTooth and Wi-Fi.
It gives a hope that it will be a trending technology
occupying the future.
