CONTENTS Introduction Network Evolution Why Gi-Fi is used Bluetooth , Wi-Fi & Gi-Fi Architecture of Gi-Fi Features / Advantages Applications Technology Considerations Conclusion

INTRODUCTIONThe name itself specifies its gigabit transfer rate.It was developed in 2008 at the National

Information And Communication Technology Research Center in MELBOURNE,AUSTRALIA.

Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip.

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.It refers to wireless communication at a data rate

of more than 1 billion per second.

Why Gi-Fi ?The common Wireless technologies currently used

are:BluetoothWi-FiThe disadvantages of existing technologies; i.e.

Slow rate. High power consumption. Low range of frequency operation.

All this gave invention to this new technology.

SPECIFICATION BLUETOOTH WI-FI GI-FI

Frequency 2.4Ghz 2.4Ghz 60Ghz

Primary Application 10 metres 91 mts 10 mts

Data transfer rate 800kbps 11Mbps 5Gbps

Power consumption 5mw 10mw 2mw

Primary Devices Mobiles phones,PDA’s,consumerElectronics etc.,

Notebook computers,Desktop Computers,Servers

Both areas

Primary Application WPAN cable replacement

WLAN Ethernet Embedded in devices

Development Start Date

1998 1990 Under development

Comparison between Bluetooth, Wi-Fi and Gi-Fi

Disadvantages of Bluetooth & Wi-Fi

The bit rates of Bluetooth is 800 Kbps and Wi-Fi has maximum of 11 Mbps

Both are having power consumptions 5mw and 10mw

The lower frequency of operation 2.4GHz.

so, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology.

FUNDAMENTAL TECHNOLOGIES IN 802.15.3C

8

It transmits multiple signals simultaneously across the wireless transmission paths within separate frequencies to avoid interference.

It uses ultra wide band Which consists of :1. High bit rate2. High security3. Faster data transmission

Architecture of Gi-Fi The core components of a GI-FI system is

the subscriber station which available to several access points .It supports standard of IEEE 802.15.3C The wireless span 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. It supports line of sight operation.

ATTRACTIVE FEATURES

High bit rate: 5 gigabits persecond, easily swapping video,audio,data files

Power consumption: 2 mill-watt power compared to 10 watt power

Security: uses IEEE 802.15.3c standards

Small size: 5mm preside 1mm antenna at bottom uses 60Ghz millimeter wave spectrum

Easily InstalledLess cost: 10$ per chip

Applications of Gi-Fi

12

1. Household appliances :It makes the wireless home and office of the future.

2. Office appliances : As it transfers data at high

speeds that made work very easy .

3. Video information transfer:We can transfer at a speed of gbps.

Gi-Fi Access Devices

Here we would use a time division duplex for both transmission and receiving.

The data files are converted from IF range to RF 60Ghz range by using 2 mixers.

We will feed this to a power amplifier, which feeds millimeter-wave antenna.

The incoming RF signal is first converted to an IF  signal centered at 5 GHz ,and then to normal data ranges, here we will use heterodyne construction for this process to avoid leakages due to direct conversion.

Due to availability of 7 GHz spectrum the total data will be transferred within seconds.

TECHNOLOGY CONSIDERATIONSThe Gi-Fi integrated transceiver chip is may be

launched by starting of next year by NICTA,Australia.

Due to less cost of chip so many companies are forward to launch with lower cost.

mw-WPAN for ultra fast data exchange has prompted companies like Intel, LG, Matsushita (Panasonic), NEC, Samsung, Si-BEAM, Sony and Toshiba.

CONCLUSION :

Within five years, we expect Gi-Fi to be the dominant technology for wireless networking. By that time it will be fully mobile, as well as providing low- cost, high broadband access, with very high speed large files swapped with in seconds which will develop wire less home and office of future. 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.
