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.
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.
FEATURES OF Gi - Fi
TECHNOLOGY
High speed of data transfer
Low power consumption
High security
Cost effective
Small size
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.
