Abstract:
Gi-Fi will helps to push wireless communications to
faster drive. For many years cables ruled the world. Optical fibers played a dominant
role for its higher bit rates and faster transmission. But the installation of
cables caused a greater difficulty and thus led to wireless access. The
foremost of this is Bluetooth which can cover 9-10mts. Wi-Fi followed it having
coverage area of 91mts. No doubt, introduction of Wi-Fi wireless networks has
proved a revolutionary solution to “last mile” problem. However, the standard’s
original limitations for data exchange rate and range, number of channels, high
cost of the infrastructure have not yet made it possible for Wi-Fi to become a
total threat to cellular networks on the one hand, and hard-wire networks, on
the other. But the man’s continuous quest for even better technology despite
the substantial advantages of present technologies led to the introduction of
new,more up-to-date standards for data exchange rate i.e., 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.It will allow wireless transfer of audio and video
data up to 5gigabits per second, ten times the current maximum wireless
transferrate, at one-tenth of the cost, usually within a range of 10 meters. It
utilizes a 5mm square chip and a 1mm wide antenna burningless than 2watts of
power to transmit data wirelessly over short distances, much like Bluetooth.
The development will enable the truly wireless
office and home of the future. As the integrated transceiver is extremely
small, it can be embedded into devices. The breakthrough will mean the networking
of office and home equipment without wires will finally become a reality. In
this we present a low cost, low power and high broadband chip, which will be
vital in enabling the digital economy of the future.
Introduction
Wi-Fi (IEEE-802.11b) and Wi-Max
(IEEE-802.16e) have captured our attention, as there are no recent developments
in the above technologies which cannot transfer data and video information at a
faster rate and led to the introduction of Gi-fi technology. Itoffers some
advantages over Wi-Fi, a similar wireless technology,that offers faster
information rate in Gbps less power consumption and low cost for short range
transmissions.
Gi-Fi or Gigabit Wireless is the
world’s first transceiver integrated on a single chip in which a small antenna
used and both transmitter receiver are integrated on a single chip which is
fabricated using the complementary metal oxide semiconductor (CMOS) process.
Because of Gi-Fi transfer of large videos, files can be done within seconds.
Researchers of Melbourne
University has come up with a wireless technology which promises high speed
short range data transfers with a speed of up to 5Gbps within a radius of 10
meters. The new wireless technology is named as Gi-Fi and operates on the 60GHz
frequency band, which is currently mostly unused. The Gi-Fi Chip developed by
the Australian researcher’s measures 5mm square and is manufactured using
existing complementary metal-oxide-semiconductor (CMOS) technology, the same
system that is currently used to print silicon chips.The best part about this
new technology is its cost effectiveness and power consumption,it consumes only
2 watts of power for its operation with antenna (1mm) included and the development
of Gi-Fi chip costs approximately $10( Rs 380) to manufacture.
In theory this technology would
transfers GB’s of your favorite high definition movies in seconds. So Gi-Fi can
be considered as a challenger to Bluetooth rather than Wi-Fi and could find applications
ranging from new mobile phones to consumer electronics
Network Evolution
Communication technology can be
divided into two types.1) wired technology and 2) wireless technology. The
evolution of wireless technology will leads to the GI-FI technology.
