INDEX:
GI-FI means gigabit fidelity that allows wireless transfer of audio and video data upto 5 gigabits per second.
It is 10 times faster than current maximum transfer rate within 10 metres range.

WHY GI FI
The reason for pushing GIFI technology is
High speed
Low cost
Small size
Low power consumption(<2mw )
When compared to earlier used networking systems i.e, WIFI or bluetooth.
ARCHITECTURE OF GI-FI
The core component of gifi is the subscriber station.
Small antenna at the subscriber station which is mounted on the roof.
It supports line of sight(LOS) operation.
It uses time division duplex for both transmission and receving.
Convertion of data from IF range to RF 60 GHz range.
The income RF signal is first down converted to an IF signal centered at 5GHz and then to normal data.
Uses heterodyne principle to avoid leakages.
Finally data is transferred.
COMPARISIONS WITH WIFI
CHARACTERISTICS GI-FI WI-FI
DEVELOPMENT START 2004 1990

TECHNICAL CONSIDERATIONS
•The GIFI integrated transceiver chip may be launched by starting of next year by NICTA,AUSTRALIA.
•Due to low cost many companies like INTEL,LG, PANASONIC ,SAMSUNG ,SONY and TOSHIBA are looking forward to launch for low cost.
•An industrial effort to define specifiction for next generation .
Within 5-6 years, we expect Gi-Fi to be the dominant technology for wireless networking.
By that time it will be high broadband access, which will develop high speed wireless home and office of future.
Gi-Fi potentially can bring wireless broadband to the enterprise in an entirely new way.
