INTRODUCTION
Gi-Fi is the world’s first tranciever integrated on a single chip.
Operates at 60GHz on the CMOS process.
Gi-Fi allows wireless transfer of audio and video data up to
5Gbps.
Gi-Fi is ten times the current maximum wireless transfer rate
usually within a range of 10 meters.

WHY Gi-fi?
The reason for pushing into Gi-Fi technology is because of :-
High power consumption
Low range of frequency operations
of earlier technologies i.e.,Bluetooth
and Wi-Fi.
Slow rate

RF signal is down converted to IF signal centered at 5GHz.
Converted to normal data range using heterodyne principle.
Filetered by using a LPF.
Amplified using an IF amplifier.

Millimeter wave antenna used will operate at 60GHz frequencywhich is unlicensed band. Because of this band, we areachieving high data rates.
Energy propagation in the 60 GHz band has uniquecharacteristics that makes possible many other benefits suchas excellent immunity to co-channel interference, high securityand frequency re-use.
WHY 60 GHz ?

FUTURE CONSIDERATIONS
The Gi-Fi integrated transceiver chip may be launched by end of this year by NICTA.
Due to less cost of chip, so many companies came 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, Si BEAM, Sony and Toshiba to
form Wireless HD, an industry-led effort to define a specification for the next
generation consumer electronics products.
