Gi-Fi is a next generation wireless technology that was developed in Australia to allow for faster wireless data transfer speeds of up to 5 gigabits per second, around 10 times faster than existing Wi-Fi technologies. It uses 60GHz frequency and has advantages over Bluetooth and Wi-Fi such as lower power consumption and cost. The core components include an IEEE 802.15.3c standard-based transceiver chip that can simultaneously transmit multiple signals to avoid interference and allows for high-speed, high-security data transmission. Companies are looking to integrate Gi-Fi technology into appliances, devices, and systems to enable the wireless home and office networks of the future.

4. INTRODUCTION To Gi-Fi:INTRODUCTION To Gi-Fi:
Wi-Fi(ieee-802.11b) and WiMax(ieee-802.16e) have captured our
attention.
As there is no recent developments which transfer data at faster
rate, as Video information transfer taking lot of time.
 This leads to introduction of Gi-Fi technology it offers
some advantages over Wi-Fi, a similar wireless technology.
It was developed at the National Information And Communication
Technology Research Center in MELBOURNE,AUSTRALIA.

6. 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.

8. Disadvantages of Bluetooth & Wi-FiDisadvantages 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 hours of time.

transceiver .
 Gi-Fi will allow 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.

12. ArchitectureArchitecture of Gi-Fiof Gi-Fi ::
 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 .
12

13. 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

14. Working of Gi-FiWorking of Gi-Fi
Use of Time Division Duplex for both
transmission and receiving.
Conversion of data from IF range to
RF60Ghz 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,highmobility

20. TECHNOLOGY CONSIDERATIONS :TECHNOLOGY CONSIDERATIONS :
 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, SiBEAM,
Sony.

 Specifically, WirelessHD has a stated
goal of enabling wireless connectivity
for streaming high- definition content
between source devices and high-
definition displays.

22.  Within five years, we expect Gi-Fi to be the
dominant technology for wireless
networking.
 which will develop wire less home and
office of future.
 Gi-Fi potentially can bring wireless
broadband to the enterprise in an entirely
new way.
