The document discusses Gi-Fi (Gigabit Wireless) technology. Gi-Fi allows wireless transfer of audio and video data at speeds up to 5 gigabits per second within a 10 meter range. It operates at 60GHz using a single-chip transceiver that is 5mm square, 1mm thin, and consumes only 2mW of power. The document compares Gi-Fi to Bluetooth and Wi-Fi, outlines the architecture and working of a Gi-Fi system, and discusses technologies that may succeed Gi-Fi such as using it for wireless home appliances and inter-vehicle communication. It predicts that within 5 years, Gi-Fi will be the dominant wireless technology.

wireless transceiver chip. It was developed at the
National Information And Communication Technology
Research Center in MELBOURNE AUSTRALIA

INTRODUCTION

4. Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single
chip it operates at 60GHz on the CMOS(Complementary metal–oxide-
semiconductor) 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
The Gi-Fi measures 5mm square ,1mm wide antenna and consumes only
2mwatts of power.It is manufactured using existing complementary metal –
oxide-semiconductor(CMOS) technology

5.  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

6.  The core components of a GI-FI system is the subscriber station
which available to several access points
 It is based on standards of IEEE 802.15.3C
 The wireless span 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. It supports line of
sight operation

of
Bluetooth and Wi-Fi
with
Gi-Fi

9. Characteristics Bluetooth Wi-Fi Gi-Fi
Frequency 2.4GHz 2.4GHz 60GHz
 Range 10 meter 100meters 10meters
 Data transfer
rate
800 Kbps 11Mbps 5Gigabps
 Power
consumption
5mW 10mW 2mW
 Primary devices Mobile phones,
Consumer electronics
office and
industrial devices
Notebooks,
dekstop
computer etc
Fax,Printer, Cellular
phones,cars etc
 Primary uses Travelling
employees,electronic
consumers,office ad
industrial workers
corporate users Wireless Home &
office appliances etc.
 Usage location Anywhere atleast two Within range of WPAN Networks

10. Disadvantages of
Bluetooth & Wi-Fi
 The bit rates of Bluetooth is
800Kbps and Wi-Fi has 11Mbps
 Both are having power consumptions
5mw and 10mw
 The lower frequency of operation
2.4GHz.For transferring large amount
of videos, audios, data files take min or
may be hours of time.
So, to have higher
data transfer rate at
lower power
consumption we
move onto Gi-Fi
technology

11.  IEEE 802.15.3c-2009 was published on September 11, 2009
It uses ultra wide band
Which consists of :
 High bit rate
 High security
 Faster data transmission
23-10-2017

12.  High speed of data transfer
 Low power consumption
 High security
 Cost effective
 Small size
 Quick deployment
 Highly portable,
 High mobility

16.  The GI-Fi integrated transceiver chip is may be launched by
starting of next year by NICTA, Australia will be first
 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,
Sony and Toshiba to form Wireless HD, an industry-led effort to
define a specification for the next generation consumer electronics
products
23-10-2017

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.
