Gi-Fi is a new wireless technology that provides data transfer speeds up to 5 gigabits per second, around 10 times faster than current Wi-Fi speeds, over short ranges of around 10 meters. It uses the 60GHz frequency band and can be integrated into a single chip. Gi-Fi has applications for wireless home devices and networks, office equipment, vehicle communication systems, and broadcasting high-definition video feeds. It is expected that within five years, Gi-Fi will become the dominant wireless technology and bring wireless broadband to both homes and enterprises.

3. • For many years cables ruled the world, optical fibers played a dominant
role for its faster transmission but installation of cable caused a greater
difficulty and lead to wireless access.
• Foremost was Bluetooth then Wi-Fi followed it. But man’s continuous
quest for even better technology led to the introduction of new ,more
up-to-date standard for data exchange rate i.e. Gi-Fi.
• Wi-Fi(ieee-802.11b) and Wi-Max (ieee-802.16e) have captured our
attention. However there is no recent developments that can transfer
data at faster rate, as Video information transfer taking lot of time.
This lead to the introduction of Gi-Fi technology.

5. • Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a
single chip that operates at 60GHz on the CMOS process.
• Gi-Fi will allow wireless transfer of audio and video data up to 5
gigabits per second.
• Gi-Fi is ten times the current maximum wireless transfer rate usually
within a range of 10 meters.
• It was developed at the National Information And Communication
Technology Research Center in Melbourne, Australia.

7. • It consists of a chip that is 5mm on each side.
• The core components of a GI-FI system is the subscriber
station which available to several access points.
• It is based on standards of IEEE 802.15.3C.
• The wireless pan is computer network used for
communication among computer devices close to one person.
• An 802.15.3c based system often uses small antenna at the
subscriber station. The antenna is mounted on the roof.It
supports line of sight operation.

8. • Initially we make use of Time Division Duplex for both
transmission and receiving.
• Then there is a conversion of data from IF range to RF
60Ghz range.
• The incoming RF signal is first down converted to an IF
signal centered at 5 GHz and then to normal data ranges.
• We make use of heterodyne principle for this process to
avoid leakages.
• And then data is transferred.

13.  The Gi-Fi integrated transceiver chip may be launched
by in the next five years by NICTA, Australia will be first .
 Due to less cost of the chip, there are many companies forward
to launch with lower cost.
 The potential of mw-WPAN for ultra fast data exchange has
prompted companies like Intel, LG, Matsushita (Panasonic),
NEC, Samsung, SiBEAM, Sony and Toshiba to form
WirelessHD, an industry-led effort to define a specification
for the next generation consumer electronics products.

15. • Within five years, we expect Gi-Fi to be the dominant
technology for wireless networking, which will develop wireless
home and offices of the future.
• We also can expect the current range of 10 meters to be
expanded and used as a broadband.
• If the success of Wi-Fi and the imminent wide usage of WiMAX
is any indication, Gi-Fi potentially can bring wireless
broadband to the enterprise in an entirely new way.
