Gi-Fi or Gigabit Wireless is the world's first Transceiver integrated on
a single chipThat operates at 60GHz on the CMOS process.
Gi-Fi allows 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.
The GiFi measures 5mm square and it is manufactured using existing
complementary metal -oxide-semiconductor(CMOS) technology.
introduction
The common Wireless technologies currently
used are:
-Blutooth
-Wifi
The disadvantages of existing technologies
- Slow rate.
- High power consumption.
- Low range of frequency operation.
Why Gi-Fi?
Evolution of Gi-Fi
Characteristics Gi-Fi Wi-Fi Bluetooth
Frequency 57-64GHz 2.4 GHz 2.4 GHz
Data Transfer Rate 5 Gbps 11Mbps 800Kbps
Range 10Meters 100Meters 10Meters
Power
Consumption
< 2 mw 10 mw 5 mw
Primary
Application
Embedded in
Devices
WLAN Ethernet WPAN Cable
Comparison
Transceiver integrated on single chip.
The core components of a Gi-Fi system is the subscriber station which
available to several access points and wireless pan network.
The wireless pan is computer network used for communication among
computer devices (including telephones and personal digital assistants)
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.
Architecture
Structure
Measures 5mm²
With antenna 1mm
Consumes 2W of
power
Operates in millimeter wave spectrum
(30-300)
Made of silicon
Uses CMOS technology
Working Principle
• Time Division Duplex for both
transmission and receiving.
Transmission :
• Data files from IF range to RF-60Ghz
range.
• Conversion using 2 mixers
• Fed to a power amplifier
• Fed to millimeter wave antenna.
Data Up linking [8]
11
› RF signal down
converted to an IF
signal at 5 GHz .
› Converted to normal
data ranges using
heterodyne principle to
avoid leakages.
› Availability of 7 GHz
spectrum . Data down link
Reception:
High speed data transfer.
Low power consumption .
High security.
Small size.
High portable and hig mobilty.
Cost effectiveness.
Advantages
Application
House hold appliances .
Video transfer.
Office appliances.
Inter vehicle communiction
Disadvantage
Short distance
RTS/CTS signals are not used
in GiFi technology unlike WiFi
standard.
Future scope
Easily Embedded Into Devices
Wireless Office and Home Equipment
Great Reliability And Ability
Greater Potential
Wireless HD
Without doubt, Gi-Fi wireless technology represents a
considerable improvement if compared to the existing
technology. The new technology provides innumerable
features that improve both the overall functionality as
well as some specific security functions.
Gi-Fi can bring wireless broadband to the enterprise in an
entirely new way.
Conclusion
Thank
You FOR YOUR ATTENTION
