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.

DISADVANTAGES OF BLUETOOTH AND WI - FIBit RatePower consumptions Frequency of 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.
