- Gi-Fi allows for wireless transfer of audio and video data at up to 5 GB per second within a 10 meter range using a single-chip 60GHz transceiver. It was developed by NICTA to provide higher data transfer rates and lower power consumption compared to Bluetooth and Wi-Fi. Gi-Fi uses Time Division Duplex to transmit and receive data at 60GHz while avoiding interference through heterodyne down-conversion to 5GHz for transmission. It is expected to enable wireless broadband connectivity in homes and offices in the near future.

 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

Comparison between Bluetooth, Wi-Fi and Gi-Fi

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.
