Gi-Fi is a new wireless technology that offers faster data transfer speeds than Wi-Fi. It uses integrated transceiver chips and small antennas to transmit data at 5 Gbps within seconds. Gi-Fi operates at 60GHz which enables high-speed data rates and transfer of large files. It has advantages over Wi-Fi such as lower power consumption and cost for short-range communication. Gi-Fi is expected to become the dominant wireless technology within 5 years, enabling wireless homes and offices of the future with easy transfer of videos and files.

3. What is Gi-Fi ?
 It offers some advantages over Wi-Fi, a
similar wireless technology. In that it offers faster
information rate in Gbps, less power consumption and
low cost for short range transmissions
 Gi-Fi which is developed on a integrated wireless
transceiver chip. In which a small antenna used and
both transmitter- receiver integrated on a single chip
which is fabricated using the complementary metal
oxide semiconductor (CMOS) process. Because of Gi-
Fi transfer of large videos, files will be within seconds.

5. Why Gi-Fi?
 The reason for pushing into Gi-Fi technology is
because of slow rate, high power consumption, low
range of frequency operations of earlier technologies
i.e. Bluetooth and Wi-Fi, see the comparisons and
features of those two technologies
Bluetooth
Wi-Fi

7. Disadvantages of Bluetooth and Wi-Fi?
 From the table we can conclude that the bit rate of
Bluetooth is 800Kbps and Wi-Fi has 11Mbps. Both are
having power consumptions 5mw and 10mw. They have
lower frequency of operation 2.4GHz. For transferring
large amount of videos, audios, data files take hours of
time. So to have higher data transfer rate at lower power
consumption we move onto GiFi Technology

8. Working Principle…
 Time Division Duplex
 Emulates Full Duplex Communication Over Half
Duplex
 Data from IF range to RF60GHz range
 Availability Of 7GHz spectrum
 Transfer Within Seconds

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

10. Gi-Fi Features
High Speed Data Transfer
Speed of Gi-Fi is 5 Gbps; which is 10 times the
data transfer of the existing technologies
Provides High Security
Gi-Fi technology is based on IEEE
802.15.3C and this standard provides more
security during transmission

11. Flexibility (No More Complex
Connections)
One of the problems with wire connections and
cables is complexity for connecting, but in the
Gigabit wireless technology simplicity is one of
the features. No wiring at
all.

12. Small in size
The size of the Gi-Fi chip is 5×5 millimetre
and can be placed in different devices such as
mobile phones.

13. Architecture of Gi-Fi :

14. 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.

15. FUNDAMENTAL TECHNOLOGIES IN 802.15.3C
*It transmits multiple signals simultaneously
across the wireless transmission paths within
separate frequencies to avoid interference

16. Frequency Of Operation…
 Point-to-point Communication At 60GHz
 Millimeter Wave Antenna At 60GHz
 High Oxygen Absorption At 60GHz
 High Data Rate Energy Propagation
 Co-channel Interference , High Security , Frequency
re-use

17. 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

18. 4- Household appliances :

19. CONCLUSION
 Within five years, we expect Gi-Fi to be the dominant
technology for wireless networking. By that time it will
be fully mobile, as well as providing low-cost, high
broadband access, with very high speed large files
swapped within seconds which will develop wireless
home and office of future.
 If the success of Wi-Fi and the imminent wide usage of
Wi-Max is any indication, Gi-Fi potentially can bring
wireless broadband to the enterprise in an entirely
new way
