4. Introduction to Gi-Fi :
Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip that operates at 60GHz on the CMOS process.
Gi-Fi allows wireless transfer of audio and video data up to 5 gigabits per second.
Gi-Fi is ten times the current maximum wireless transfer rate usually within a range of 10 meters.

6. HOW GIFI IS DEVELPED
It was developed by Melbourne University- based laboratories of NICTA(National ICT Australia Limited).
NICTA develops a world’s first transceiver in semiconductor technology for the wireless home and office of the future.

8. Why Gi-Fi ? The reason for pushing into Gi-Fi technology is because of
slow rate,
high power consumption,
low range of frequency operation of
earlier technologies i.e. Bluetooth and Wi-Fi.

10. Disadvantages of Bluetooth & Wi-Fi
The bit rates of Bluetooth is 800 Kbps and Wi-Fi has maximum of 11 Mbps
Both are having power consumptions 5mw and 10mw
The lower frequency of operation 2.4GHz.
so, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology.

11. Architecture of Gi-Fi
The core component of a Gi-Fi system is the subscriber station .
It supports standard of IEEE C Wireless PAN
An C based system often uses small antenna at the subscriber station.

12. FUNDAMENTAL TECHNOLOGIES IN 802.15.3C
It transmits multiple signals simultaneously across the wireless transmission paths within separate frequencies to avoid interference.
It uses ultra wide band
Which consists of :
High bit rate
High security
Faster data transmission
GIGABIT WIRELESS PAN NETWORKS

13. FEATURES OF Gi-Fi High speed of data transfer Low power consumption
High security
Cost effective
Small size
Quick deployment
Highly portable, high mobility

14. Applications of Gi-Fi Household appliances :
It makes the wireless home and office of the future.
Office appliances :
As it transfers data at high speeds that made work very easy .
Video information transfer:
We can transfer at a speed of gbps.

15. Applications Cont...

17. Technology Considerations
Due to less cost of chip so many companies are
looking forward to launch with lower cost.
Specifically, Wireless HD has a stated goal of
enabling wireless connectivity for streaming high -definition content between source devices
and high-definition displays.

18. 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.
