INTRODUCTIONGi - Fi or Gigabit Wireless is the worlds first transceiver integrated on single chip that operates at 60GHz on the CMOS process.It will allow wireless transfer of audio and video data up to 5 gigabits per second.

HISTORYThe 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.

MAN BEHIND GI-FI

WHY GI FI ?Slow Rate.High Power Consumption. Low Range of Frequency Operation.

ARCHITECTURE OF GI - FIThe core component of GI FI is the subscriber station.It supports standard of IEEE 802.15.3C.An 802.15.3C based system uses small antenna at subscriber station.It supports line of sight operation.

FEATURES OF GI - FIHigh speed of data transfer - 5 gigabits per secondLow power consumption - 2 watt powerHigh securityCost effective 10$ per chipSmall size - 5mm per sideEasily Installed Highly portable

APPLICATIONSHousehold Appliances-Consumers could typically download a high definition movie in a matter of seconds to music player or smart phone and having got home could play it on a home theatre system or store it on a home server for future viewing.

Office Appliances- It transfers data at high speeds which made work very easy, it also provides high quality of information from internet.

Video Information Transfer-Data transfer rate is same for transfer of information from a PC to a cell or a cell to a PC. It can enable wireless monitors, the efficient transfer of data from digital camcorders, wireless printing of digital pictures from a camera without the need for an intervening personal computer.4. Inter vehicle communication

TECHNOLOGY CONSIDERATIONSDue to less cost of chip so many companies are looking forward to launch with lower cost.The Gi - Fi integrated transceiver chip may be launched by starting of next year by NICTA, Australia will be first .

CONCLUSIONWithin five years, we expect Gi - Fi to be the dominant technology for wireless networking.If success of Wi - Fi and the imminent wide usage of Wi MAX is any indication, Gi - Fi potentially can bring broadband to the enterprise in an entirely new way.
