For many years, cables ruled the world. Optical fibers
played a dominant role because of 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 9-10metres.
Wi-Fi followed it having coverage area of 91metres. No doubt, introduction of
Wi-Fi (Wireless Fidelity) has brought 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 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 .It will help to push wireless communications to faster
drive.
Gi-Fi(Gigabit Fidelity) 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 2 mw of power to transmit
data wirelessly over short distances, much like Bluetooth.
The development will enable the truly wireless office and
home in 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 paper we present a low cost, low power and high
broadband chip, which will be vital in enabling the digital economy of the
future.
