3. Gi-Fi means Gigabit Wireless is World's first
transceiver integrated on a single chip that operates at
60GHz on the CMOS process..
Gi-Fi allows wireless transfer of audio and video data
at upto 5 GB per second.
Transfer data within a range of 10 ms.
It was developed by Melbourne University-based
laboratories of NICTA Limited.
National Information And Communication Technology Australia

INTRODUCTION TO GI-FI :
6. 6
The reason for pushing into Gi-Fi technology is because of
Slow rate,
High transfer rate(Gbps),
Low power consumption(<2 MW),
Lower cost of production,
As compared to earlier technologies i.e. Bluetooth,
Wi-Fi etc.
WHY GI-FI
7. SPECIFICATION BLUETOOTH WI-FI GI-FI

Comparison between Bluetooth, Wi-Fi and Gi-Fi
7
8. 8
The bit rates of Bluetooth is 800 Kbps and Wi-Fi has
maximum of 11 Mbps
Both are having power consumptions 5mw and 10mw
The lower frequency of operation 2.4GHz.
o so, to have higher data transfer rate at lower power consumption we move
onto Gi-Fi technology.
Disadvantages of Bluetooth & Wi-Fi
9. 9
The core components of a GI-FI system is the subscriber station
which available to several access points.`
It supports standards of IEEE 802.15.3C.`
The wireless pan is computer network used for communication
among computer devices (including telephones and PDA’s) 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.
ARCHITECTURE OF GI-FI
10. 10
Use of Time Division Duplex for both transmission and
receiving.
Here conversion of data from IF range to RF 60Ghz range.
The incoming RF signal down converted to an IF signal
centered at 5 GHz and then converted to normal data ranges.
Using heterodyne principle to avoid leakages.
And then finally data is transferred.
WORKING OF GI-FI
11. 11
High speed of data transfer. -5GB/s
Low power consumption. -<2 watt power
High security.`
Cost effective. (cheap rate compare to
others)
Small size. (5mm/side)
Easily Installed.`
FEATURES OF GI-FI :
12. 12
• House hold appliances :
-it makes the wireless home of the future:
• Office appliances :
As it transfers data at high speeds that
work very easy.
• Video information transfer:
We can transfer at a speed of Gbps.
APPLICATIONS OF GI-FI
13. 13
Within few years, expecting Gi-Fi to be the dominant technology for
wireless networking.
Which will develop wireless 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.
