DEFINITION
The process of Gi-Fi would use a chip that transmits at
an extremely high 60GHz frequency versus the 5GHz used
for the fastest forms of Wi-Fi. The sheer density of the
signal would allow a chip to send as much as five gigabits
per second. While the spectrum would limit the device to
the same 33-foot range as Bluetooth or UWB (Ultra-Wide
Band), it could theoretically transfer an HD movie to a cell
phone in seconds, the researchers claim [7].
The size of the Gi-Fi chip is 5×5 millimeter and can be
placed in different devices such as mobile phones, as it is
shown in the fig. 1 and fig. 2.
Low Cost Chip
Gi-Fi’s chip uses only a tiny one-millimeter-wide antenna
and less than 2mili watts of power. Low-cost chip allows
technology to be readily incorporated into multiple devices.
The chip in Gi-fi would likely cost about $10 or less to build
[8, 12]. This and a small design would allow cell phones and
other small devices to add the technology without significantly
drive up the price, according to the company. Gi-Fi is based
on an open, international standard. Mass adoption of the
standard, and the use of low-cost, mass-produced chipsets,
will drive costs down dramatically, which is very less in
compare to present technologies.
C. Security
Among the factors that have held back enterprise uptake of
wireless LANs outside green field sites have been security
fears and lack of performance compared to wire line Ethernet.
About 70 per cent of firms have deployed their WLAN in a
secure firewall zone but are still using the old WEP protocol,
which does not protect the application layer effectively, so
better encryption is urgently needed [9]. Secure encryption
technology in Gi-Fi ensures privacy and security of content
FUTURE OF GI-FI
A completely integrated single chip transceiver has been
fabricated, tested and demonstrated in Gi-Fi chip and a
transceiver with integrated phased array antenna on 65nm
CMOS technology has been sent for fabrication. Gi-Fi
technology demonstrates the world’s first fully integrated
transceiver on CMOS technology operating at 60 GHz and
provides new technique for integrating antennas on CMOS.
Demonstrations of Gi-Fi technology can be arranged
showing the huge potential it has to change the way consumers
use their in-home electronic devices. The GiFi team is looking
for partners interested in commercializing its 60GHz chips and
with growing consumer adoption of High-Definition (HD)
television, low cost chip and other interesting features of this
new technology it can be predicted that the anticipated
worldwide market for this technology is vast. Within next few
years, we expect Gi-Fi to be the dominant technology for
wireless networking. By providing low-cost, high broadband
access, with very high speed large files swapped within
seconds it could develop wireless home and office of future.
CONCLUSION
In this paper Gi-Fi technology is defined that will allow
wireless transfer of audio and video data up to 5 gigabits per
second, ten times the current maximum wireless transfer rate,
at one-tenth of the cost, usually within a range of 10 meters
that operates at 60GHz on the CMOS process. This technology
removes cables that for many years curled the world and
provides high speed data transfer rate. The comparison that is
performed between Gi-Fi and existing wireless technologies in
this paper shows that these features along with some other
benefits such as Low-cost chip, No Frequency Interference,
Low Power Consumption and High Security that are explained
in detail in this paper, makes it suitable to replace the existing
wireless technologies for data transmission between devices
that are placed in the short distances from each other. Gi-Fi
technology has much number of applications and can be used
in many places and devices such as smart phones, wireless pan
networks, media access control and mm-Wave video-signals
transmission systems. This chip could also replace HDMI
cables and develop wireless home and office of future. Finally
some of the future works related to Gi-Fi has given and it is
conspicuous that more research should be done in the field of
this new wireless technology and its applications.
