4. Introduction to 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.

5. Cables

6. Currently Using Technologies:-
BLUETOOTH
WI-FI

7. Comparison between Bluetooth, Wi-Fi & Gi-Fi:-

Consumer Electronics etc.
Notebook Computers,
Desktop Computers,
Servers.
Both Areas
Primary Application WPAN: Cable
replacement

replacement
Both
Development Start Date 1998 1990 Under Development

8. Disadvantages of Bluetooth and Wi-Fi:-
The bit rate of Bluetooth is 800Kbps and Wi-Fi has 11Mbps.
Both are having power consumptions of 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 Gi-Fi Technology.

9. 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 of earlier technologies

10. Architecture of Gi-Fi:-
 Transceiver integrated on single chip
 The core components of a Gi-Fi system is the subscriber station which available to several
access points and wireless pan network.
 It supports standard of IEEE 802.15.3C.
 The wireless pan is computer network used for communication among computer
devices (including telephones and personal digital assistants) close to one person
 An 802.15.3C based system often uses small antenna at the subscriber station. The antenna is
mounted on the roof.

11. Transceiver Gi-Fi Chip:-

12. How Gi-Fi Technology works:-
 The data files like audio or video are converted from IF range to RF
range of 60GHz.
 This range will be feed to a power amplifier and forwarded to wave
antenna.
 The incoming signals i.e. RF signals are first down sampled to an IF
signal and further converted to normal data ranges.
 Available of 7 GHz spectrum helps us to transfer the data files within
seconds.

13. GI-FI Access devices:-

14. Features of Gi-Fi Technology:-
High speed of data transfer
Low power consumption
High security
Cost effective
Small size

15. APPLICATIONS:-
 In wireless PAN networks.
 Inter-vehicle communication system.
 Huge data file transfer.
 Office appliances.
 Video information transfer.

16. Benefits of GI-FI Technology:-
• Removing Cables
• Cost of Chip is low
• Privacy and Security
• Flexibility

17. 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 with in
seconds which will develop wire less home and office of future.
 If the success of Wi-Fi and the imminent wide usage of WiMAX is any
indication, Gi-Fi potentially can bring wireless broadband to the enterprise
in an entirely new way.
