Introduction to Gi-Fi :
Gi-Fi or Gigabit Wireless is the 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 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 GiFi operates on the 60GHz frequency band.
The GiFi measures 5mm square and it is manufactured using existing complementary metal – oxide-semiconductor(CMOS) technology.
It was developed at the National Information And Communication Technology Research Center in MELBOURNE,AUSTRALIA.

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.
Why Gi-Fi ?
Comparison of Bluetooth and Wi-Fi with Gi-Fi
characteristics Bluetooth Wi-Fi Gi-Fi
Frequency 24GHz 24GHz 60GHz
Range 10 meter 100meters 10meters
Primary application WPAN cable replacement WLAN Ethernet Embedded in devices
Data transfer rate 800 Kbps 11Mbps 5Gigabps
Power consumption 5mw 10mw 2mw
Primary devices Mobile phones,PDAs,consumer electronics,office and industrial devices
Notebooks,desktop computer
Fax,Printer, Cellular phones
Primary uses Travelling employees,electronics consumers,office ad industrial workers
corporate users Wireless Home & office appliances ,etc.
Usage location Anywhere atleast two bluetooth device exist-ideal for roaming outside buildings
Within range of WLAN infrastructure,usually inside a buildings
WPAN Networks
Specification Bluetooth S&G IEEE 802.11b,WBCA IEEE 802.15.3C
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 hours of time.
So, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology
What Is Gi-Fi ?
Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip that operates at 60GHz on the CMOS process.
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.
Gigabit wireless: The Gi-Fi integrated wireless transceiver chip, developed at the National ICT Research Centre, Australia.
Architecture of 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 (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.
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
Working 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.
FEATURES OF GI-FI :
High speed of data transfer Low power consumption High security Cost effective Small size Quick deployment Highly portable,highmobility
APPLICATIONS OF GI-FI
1. House hold appliances :
-it makes the wireless home
of the future:
2. Office appliances :
3. Video information transfer:
4. Inter-vehicle communication system:
5. Broadcasting video signal transmission system in sports stadium:
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 and Toshiba to form Wireless HD, an industry-led effort to define a specification for the next generation consumer electronics products.
Next To Gi-Fi
Specifically, Wireless HD has a stated goal of enabling wireless connectivity for streaming high- definition content between source devices and high-definition displays.

CONCLUSION :
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.
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.
