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 changes, 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 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. It utilizes a
5mm square chip and a 1mm wide antenna burning less than 2m watts of power to transmit data wirelessly over
short distance, much like Bluetooth. The breakthrough will mean the networking of office and home equipment
without wires will finally become a reality. In this report we present a low cost, low power and high broadband chip,
which will be vital in enabling the digital economy of the future.
Wi-Fi (ieee-802.11b) and WiMax (ieee-802.16e) have captured our attention. As there is no recent
developments which transfer data at faster rate, as video information transfer taking lot of time. This leads to
introduction of Gi-Fi technology. It 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. GiFi
which is developed on a integrated wireless transceiver chip. In which a small antenna used and both
transmitter- receiver 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 will be within seconds.
In theory this technology would transfers GB‟s of our 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. GiFi allows a full-length high definition movie to be transferred
between two devices in seconds to the higher megapixel count on our cameras, the increased bit rate on our
music files, the higher resolution of our video files, and so on.
We demand more than ever, but we also want this content to be transferred in the most expedient manner
possible. 802.11g and 802.11n are fine and all, but some people want to push the envelope even further. This
chip is 5mm per side and it can operate at a frequency of 60GHz while wi fi chip can operate only at 2.4GHz.
This have low power conception of 2 watt comes and comes with 1mm antenna.
