Gi-Fi, or gigabit wireless, enables wireless data transfer rates exceeding one billion bits per second, offering speeds up to 5 gigabits per second at a fraction of existing costs. It boasts features like high frequency reuse, portability, and a low-cost chip that ensures data security and ease of deployment in various applications. With its potential to revolutionize wireless communication, Gi-Fi is expected to dominate future networking by delivering high-speed access with reduced interference and energy consumption.

3. 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 CHIP THAT
OPERATES AT 60GHz ON THE CMOS CHIP.

4. TECHNOGIES USED IN GI-FI:
MULTIPLE INPUT -MULTIPLE OUTPUTS:
MIMO IS AN EMERGING COST EFFECTIVE TECHNOLOGY THAT
OFFERS SUBSTANTIA L LEVERAGES IN MAKING 1Gbps WIRELESS
LINKS A REALITY.USING THIS PRINCIPLE WE CAN THE 1Gbps DAT
RATE REQUIREMENT IF THE PRODUCT OF BANDWIDTH AND
SPECTRAL EFFICIENCY EQUALS 10^9..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.

5. FEATURES OF GI-FI:
 HIGH LEVEL OF FREQUENCY RE-USE ENABLED
 HIGHLY PORTABLE
 FLEXIBLE 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

6. 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

7. HOW BIG IS THE GI-FI CHIP??

8. 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.

10. APPLICATIONS OF GI-FI:
GI-FI ACCESSABLE DEVICES:
Broadcasting video signal transmission
system in sports stadium

11. Office appliances : Video transmission :
Inter vehicle communication:

12. Comparison of gi-fi with other
technologies:

13. 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.

14. 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.
