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.

7. 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.

8. Comparison between Bluetooth & Wi-
Fi

9. 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.

10. Architecture of Gi-Fi
The core component of a Gi-Fi system is the
subscriber station .
It supports standard of IEEE 802.15.3C Wireless
PAN
An 802.15.3C based system often uses small
antenna at the subscriber station.
It supports line of sight operation.

11. 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 :
1. High bit rate
2. High security
3. Faster data transmission

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

13. Applications of Gi-Fi
1. Household appliances :
It makes the wireless home and office of
the future.
2. Office appliances :
As it transfers data at high speeds that
made work very easy .
3. Video information transfer:
We can transfer at a speed of gbps.
4. Inter-vehicle communication system

14. 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.

15. 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.
