3. INTRODUCTION
• Gi-Fi stands for Gigabit Wireless and it is worlds
first transceiver integrated on a single chip.
• It operates at 60 GHz on the CMOS process.
• Allows wireless transfer of audio and video data at
up to 5 GB per second.

4. LITERATURE SURVEY
1. Gi-Fi: Future of Wireless Technology
Author : Shikhar Bahl, Rishabh Rai ,June 2015
 Proposed a model in which they implement a technology which gain
flexibility of infrastructure, reduce capital expenditure, gain
advantages over competitors and to solve business problems.
2. Effective GI-FI Wireless Technology
Author : M.karthika, A.K.SathiyaBama ,Jan 2016
 Proposed that wireless dual band router and wireless dual band USB
adapter are based on the next generation Wi-Fi technology, which is a
new wireless computer networking standard in the 802.11 ac family.

Features
Author :Rakesh Kumar Jha ,Pooja Kharga, 2015
 Proposed a model that MIMO (Multiple input Multiple output) increase
the capacity 10 times and the system enables significant reduction of
latency on the radio interface using the low numbers.
4. A Survey on GI-FI Technology
Author :Sonali B. Maind, Pravin V. Khawse, May 2015
 Proposed a model that the introduction of Gi-Fi wireless network has
proved a solution to Bluetooth and Wi-Fi problem, the limitations for
data exchange rate and range.

6. HISTORY
 It was developed at the
National Information And
Communication Technology
Research Center in
MELBOURNE,AUSTRALIA.
 It can have a span of
10 meters.

8. 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.

9. COMPARISON WITH
BLUETOOTH , WIFI AND GI-FI

10. Disadvantages of Bluetooth &
Wi-Fi
 The bit rates of Bluetooth is
800Kbps and Wi-Fi has 11Mbps .
 The 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

11. Architecture of Gi-Fi
 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.

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 :
1. High bit rate
2. High security
3. Faster data transmission
GIGABIT WIRELESS PAN NETWORKS

13. WORKING OF GI-FI
 Use of Time Division Duplex for both transmission and
receiving.
 Conversion of data from IF range to RF 60Ghz range.
 The incoming RF signal is first down converted to an IF
signal centered at 5 GHz and then to normal data
ranges.
 Then use heterodyne principle for this process to avoid
leakages.
 And then data is transferred.

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

16. GI-FI CHIP

17. BENEFITS OF GI-FI
 Removing cables
 Low cost chip
 Security
 Simplicity
 Enabling the future of information management

18. APPLICATIONS
 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.

19. Continued….
 Inter-vehicle communication

20. TECHNOLOGY
CONSIDERATION
 Due to less cost of chip so many companies are forward to
launch with lower cost.
 The potential of mw-WPAN for ultra fast data exchange has
prompted companies like Intel, LG, Matsushita (Panasonic),
NEC, Samsung, SiBEAM, Sony and Toshiba to form
Wireless HD, an industry-led effort to define a specification for
the next generation consumer electronics products.

21. FUTURE SCOPE
 Easily Embedded Into Devices
 Wireless Office and Home Equipment
 Great Reliability And Ability
 Greater Potential
 Wireless HD

22. 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
files can be swapped within seconds.
 Gi-Fi can bring wireless broadband to the enterprise in
an entirely new way.
