GI-FI
The Technology of New Era
-Blog By Akansha Jain (Final Year Student, ETC, ACET, Nagpur)
Idea: Gi-Fi (Gigabit Fidelity) or Gigabit Wireless refers to
wireless communication at a data rate of more than one billion bits (gigabit)
per second. Gi-Fi offers some advantages over Wi-Fi, a similar wireless
technology. In that it offers faster information rate in Gbps, less power
consumption and low cost for short range transmissions as compare to current
technology. Gi-Fi consists of a chip which has the facility to deliver
short-range multi gigabit data transfer in a local environment and compared to
other technologies in the market it is ten times faster. Gi-Fi has the data
transfer speed up to 5 gbps within a short range of 10 meters. It operates on
the 60GHz frequency band. Gi-Fi is developed on an integrated wireless
transceiver chip. It has both transmitter & receiver, integrated on a
single chip which is fabricated using the CMOS (complementary
metal–oxide–semiconductor) process and it also consists of a small antenna.
GiFi allows transferring large videos, audio files, data files etc. within few
seconds.
Outline: Gigabit Wireless is the world‟s first
transceiver integrated on a single chip which operates at 60GHz on the CMOS
process. Wireless transfer of large files, audio and video data upto 5 gigabits
per second is possible with this chip. The cost of wireless transfer rate is
one-tenth and it provides ten times faster speed within a range of 10 meters.
It uses a 5mm square chip and a 1mm wide antenna burning less than 2milli watts
of power to transmit data wirelessly over short distances, similar to
Bluetooth. Gi-Fi technology provides various different features like High speed
of data transfer, Low power consumption, High security, Cost effective, Small
size, Quick deployment, Highly portable, high mobility etc.
ARCHITECTURE OF GI-FI: The main and important component of a Gi-Fi system is its subscriber
station which is available to several access points. It supports standard of
IEEE 802.15.3C which uses small antenna at the subscriber station.. For the
communication among different computer devices, which includes telephones and
PDA, it supports millimeter-wave wireless PAN network. In this network, the
antenna is mounted on the roof and it supports Line Of Sight (LOS) operation.

What is 802.15.3C Technologies?
This millimeter-Wave WPAN will operate in the
new and clear band including 57-64 GHz unlicensed band defined by FCC 47 CFR
15.255. The millimeter-wave WPAN will allow high coexistence (close physical
spacing) with all other microwave systems in the 802.15 family of WPANs. It
transmits multiple signals simultaneously across the wireless transmission
paths within separate frequencies to avoid interference.

between Gi-Fi, Wi-Fi & Bluetooth
FEATURES OF GI-FI:
·
High Security: As the
IEEE 802.15.3C provides more security, it provides link level and service level
security, where these features are optional. Point-to-point wireless systems
operating at 60 GHz have been used for many years by the intelligence community
for high security communications and by the military for satellite-to satellite
communications.
·High speed data transfer: The main invention of Gi-Fi is to
provide higher bit rate Because of this high speed data transfer, we can
transfer large video, audio, data files within seconds. .As the name itself
indicates data transfer rate is in Giga bits per second it is 10 times faster
than the present data transfer rate. The speed of Gi-Fi is 5 Gbps. An entire
High-Definition (HD)movie could be transmitted to a mobile phone in a few
seconds, and the phone could then upload the movie to a home computer or screen
at the same speed.
· Small
Size: The chip, just 5mm per side, has a tiny 1mm antenna and uses the 60GHz millimeter-wave‟ spectrum.
· Low
Power Consumption: This is the best feature because although the large amount
of information is transferred, it utilizes milliwatts of power only. Generally
in present technologies it takes 10mwatt power, which is very high but this
technology consumes only 2mwatt power for data transfer of gigabits of
information.
·
Cost-effective: Gi-Fi is based on an open, international standard due to which
the use of low-cost, mass-produced chipsets, will bring down the cost
automatically. This also results in integrated wireless transceiver chip which
transfers data at high speed and low power at low price of $10 only which is
very less as compared to present systems. As time will pass and development
increases , the price of Gi-Fi will be decreased.
APPLICATIONS:
· House Hold Appliances: Consumers could typically download
a high definition movie from a kiosk in a matter of seconds to music player or
smart phone and having got home could play it on a home theatre system or store
it on a home server for future viewing, again within a few seconds, high speed
internet access, streaming content download (video on demand, HDTV, home
theater, etc.), real time streaming and wireless data bus for cable
replacement.
· Office Appliances: As it transfers data at high
speeds which made work very easy, it also provides high quality of information
from internet.
· Video information transfer: By using present technologies
video swapping takes hours of time, whereas by this we can transfer at a speed
of Gbps. Data transfer rate is same for transfer of information from a PC to a
cell or a cell to a PC. It can enable wireless monitors, the efficient transfer
of data from digital camcorders, wireless printing of digital pictures from a
camera without the need for an intervening personal computer and the transfer of
files among cell phone handsets and other handheld devices like personal
digital audio and video players.
· Future Considerations: As the range is limited to shorter
distances only we can expect the broad band with same speed and low power
consumption.
· Easily Embedded Into Devices
· Wireless Office and Home Equipment
· Great Reliability And Ability
· Greater Potential
· Wireless HD
INFERENCE:
Within five years, Gi-Fi is the powerful
technology for wireless networking. In this paper, the comparison is performed
between Gi-Fi, Bluetooth and Wi-Fi technologies shows that these features along
with some other benefits make it suitable to replace the existing wireless
technologies. Gi-Fi offers High speed of data transfer, Low power consumption,
High security, Cost effective, Quick deployment, Small size, Highly portable,
high mobility etc.for short range transmissions as compare to current technology.
Gi-Fi can be used in many devices such as media access control, Smartphone‟s,
wireless PAN network. high cost of infrastructure have not yet possible for
wi-fi to become a power network, then towards this problem the better
technology despite the advantages of rate present technologies led to the
introduction of new Gi-Fi. It removes cables that for many years ruled over the
world and provides high speed data transfer rate.
