WHAT IS GI-FI?GI-FI OR GIGABIT WIRELESS REFERS TO A WIRELESS COMMUNICATION AT A DATA RATE OF MORE THAN ONE BILLION BITS PER SECOND.IT WILL ALLOW WIRELESS TRANSFER OF AUDIO AND VIDEO DATA UP TO 5 GIGABITS PER SECOND,TEN TIMES THE CURRENT MAXIMUM WIRELESS TRANSFER RATE AT ONE-TENTH THE COST.IT IS WORLD’S FIRST TRANSCEIVER INTEGRATED ON A SINGLE CHI THAT OPERATES AT 60GHz ON THE CMOS

FEATURES OF GI-FI:HIGH LEVEL OF FREQUENCY RE-USE ENABLEDHIGHLY PORTABLEFLEXIBLE ARCHITECTURE:IT DEPLOYS LINE OF

SIGHT OPERATION HAVING ONLY SHORTER COVERAGE.

MULTI-GIGABIT WIRELESS TECHNOLOGY THAT REMOVES THE NEED FOR CABLES BETWEEN CONSUMER ELECTONIC DEVICES

100 TIMES FASTER THAN CURRENT SHORT RANGE WIRELESS TECHNOLOGY

COST EFFECTIVE AND LESS POWER CONSUMPTION WITH HIGH SECURITY

WHY GI-FI?GI-FI WILL HELP TO PUSH WIRELESS

COMMUNICATION TO A FASTER DRIVE.AS THE INTEGRATED CHIP IS EXTREMELY SMALL,IT CAN BE EMBEDDED INTO DEVICES WHICH WILL MEAN THE NETWORKING OF OFFICE AND HOME EQUIPMENTS WITOUT WIRES BECOMES A REALITY.

TECHNOLOGIES USED IN GI-FI:MULTIPLE INPUT -MULTIPLE OUTPUTS:MIMO IS AN EMERGING COST EFFECTIVE TECHNOLOGY THAT OFFERS SUBSTANTIA L LEVERAGES IN MAKING 1Gbos WIRELESS LINKS A REALITY.USING THIS PRINCIPLE WE CAN THE 1Gbps DAT RATE REQUIREMENT IF THE PRODUCT OF BANDWIDTH AND SPECTRAL EFFICIENCY EQUALS 109.THE PERFORMANCE IMPROVEMENTS RESULTING FROM THE USE OF MIMO SYSTEM ARE DUE TO : -ARRAY GAIN --DIVERSITY GAIN –SPATIAL MULTIPLEXING GAIN –INTERFERENCE REDUCTION

SYSTEM-ON-A-PACKAGE:WIRELESS DEVICES IMPLEMENTING COMPLEX FUNCTION REQUIRE A LARGE AMOUNT OF CIRCUITRY AND HENCE,REQUIRES A LARGE CONVENTIONAL PACKAGE.

HOW BIG IS THE GI-FI

CHIP?

ADVANTAGES OF GI-FI REMOVING CABLES: OVER YEARS,OPTICAL FIBRES HAVE BEEN RULING THE WORLD.BUT

THE INSTALLATION OF WIRES CAUSED DIFFICULTIES WHICH LED TO WIRELESS ACCESS.GI-FI TECHNOLOGY REMOVES NEED FOR CABLE TO CONNECT CONSUMER ELECTRONICS DEVICES AND ALL THE DEVICES IN THE RANGE OF 10MTRS CAN BE CONNECTED IN ORDER TO TRANSMIT THE DATA WIRELESSLY

• LOW COST CHIP: THIS CHIP WOULD COST AROUND $10 OR LESS TO BUILD AND CAN FIT ONTO ANY DEVICE WITHOUT ANY EXTRA EXPENSE.

• SECURITY: THE FACTORS THAT HAVE HELD BACK ENTERPRISE UPTAKE OF WIRELESS LANs OF PERFORMANCE COMPARED TO WIRE LINE ETHERNET.SECURITY ENCRYPTION TECHNOLOGY IN GI-FI ENSURES PRIVACY AND SECURITY OF CONTENT.

• SIMPLICITY: GI-FI TECHNOLOGY ALSO ENABLES THE FUTURE OF INFORMATION MANAGEMENT IS EASY TO DEPLOYMENT WITH THE SMALL FORM FACTOR.GI-FI HAS FLEXIBLE ARCHITECTURE

APPLICATIONS OF GI-FI:

GI-FI ACCESSABLE DEVICES:

Broadcasting video signal transmission system in sports

stadium

Office appliances : Video transmission :

Inter vehicle communication:

Comparison of GI-FI with other technologies:

FUTURE OF GIFI:A COMPLETELY INTEGRATED SINGLE CHIP

TRANSCEIVER HAS BEEN FABRICATED,TESTED AND DEMONSTRATE IN GI-FI CHIP AND A TRANSCEIVER WITH INTEGRATED PHASED ARRAY ANTENNA ON 65nm CMOS TECHNOLOGY HAS BEEN SENT FOR FABRICATION.THE GIFI TEAM IS LOOKING FOR PARTNERS INTERESTED IN COMMERCIALISZING ITS 60GHz CHIPS AND WITH GROWING CONSUMER ADOPTION OF HIGH DEFINATION TELEVISON ,LOW COST CHIP AND OTHER INTERESTING FEATURES OF THIS TECHNOLOHY ,IT CAN BE PREDICTED THAT THE ANTICIPATED WORLDWIDE MARKET IS VAST FOR THIS TECHNOLOGY.

CONCLUSION:WITHIN NEXT FEW YEARS ,WE EXPECT GI-

FI TO BE THE DOMINANT TECHNOLOGY FOR WIRELESS NETWORKING.BY PROVIDING LOW COST,HIGH BOADBAND ACCESS,WITH VERY HIGH SPEED LARGE FILES SWAPPED WITHIN SECONDS;IT COULD DEVELOP WIRELESS HOME AND OFFICE OF FUTURE.NO FREQUENCY INTERFENCE,LOW POWER CONSUMPTION AND HIGH SECURITY MAKES IT SUITABLE TO REPLACE THE EXISTING TECHNOLOGIES.
