HISTORY The NICTA GI-FI research team has

succeeded in taking complex 60GHz

transmission technology and where it can

be built on a single silicon chip.

It can have a span of 10 meters.

Why GI-FI

WORKING OF GI-FI

Use time division duplex (TDD) for both

transmission and receiving.

Data are up converted from IF range to RF 60Ghz

range by using 2 mixers and we will fed this to an

power amplifier, which feeds millimeter wave

antenna.

Incoming RF signal is first down converted to an IF

signal centered at 5 Ghz and then to normal data

ranges.

TIME DIVISION DUPLEXING

Transmit signal is separate from receiver by

the allocation of different time slot.

Signal frequency channel is assign to both

the transmitter and receiver.

In this, there are allocated time slot for both

transmitter and receiver.

Gigabit wireless: The Gi-Fi integrated

wireless transceiver chip, developed at

the National ICT Research Centre,

Australia.

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 wirelesss 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. It

supports line of sight operation.

GI-FI ACCESS DEVICES

FEATURES OF Gi - Fi

TECHNOLOGY

High speed of data transfer

Low power consumption

High security

Cost effective

Small size

APPLICATIONS OF GI-FI

1. House hold appliances :- it

makes the wireless home of the

future18

FUTURE WORK

As the range is limited to only

we can except the broad band

with same speed and low

power consumption

CONCLUSION

Within five years, we expect Gi-Fi to be the dominant

technology for wireless networking.

Gi-Fi can bring wireless broadband to the enterprise in

an entirely new way.
