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.

COMPARISON

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

Working principle
Time Division Duplex
Technology used
1.Multi input multi output
2.System On Package

EXPLANATION
Data files from IF range to RF range(60GHz).
Conversion using 2 mixers.
Fed to a power amplifier.
Fed to a millimeter wave antenna.

EXPLANATION
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.

WHY 60 GHz ?
Millimeter wave antenna used will operate at 60GHz frequency
which is unlicensed band. Because of this band, we are
achieving high data rates.
Energy propagation in the 60 GHz band has unique
characteristics that makes possible many other benefits such
as excellent immunity to co-channel interference, high security
and frequency re-use.

ADVANTAGES OF Gi-Fi
Profitable Chip
 Small in size
 Faster Data Transmission
 Low Power Consumption
 Security

APPLICATIONS
1.Gi-Fi access devices

2. Broadcasting Video Signal Transmission
System in
Sports Stadium
3. Office Appliances

4. Video Information Transfer
5. Inter Vehicle Communication System

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.
