2. Why GI-FI
The disadvantages of existing technologies;ie
 Slow rate.
 High power consumption.
 Low range of frequency operation.
Give invention to this new technology

3. Currently using technologies:
 Bluetooth.
 Wi-Fi.

5. What is GI-FI?
 GI-FI means gigabit wireless.
 Worlds first transceiver integrated on single
chip.
 Operates on 60ghz on the CMOS process.
 Allows wireless transfer of audio and video data
at upto 5gb per second.
 Transfer data within an indoor environment
usually within a range of 10ms.

6. 5mm Gi-Fi chip

7. Working in GI-FI
 Time-division multiplexing.
 Intermediate frequency.
 Radio frequency.
 Hetrodyne principle.

8. Why 60GHZ?
 Immunity to co-channel interface.
 High security.
 Frequency re-use.
 High oxygen absorption at 60GHZ
attenuates signals over distance.

9. FEATURES OF GI-FI
 Small in size.
 Portable.
 High speed of data transfer.
 Low power consumption.
 Cost-effective.

10. GI-FI ACCESS DEVICES

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

12. Inter-vehicle communication

14. CONCLUSION.
Within five years,we expect Gi-Fi to
be the dominant technology for
wireless networking.
