4G TECHNOLOGY-THE WAY AHEAD

4G-MOST OF US HAVE HEARD ABOUT IT IN OUR DAY-TO-DAY LIFE BUT ONLY A FEW ARE AWARE WHAT IT IS.

I CALL IT A “MAGIC”.

YOU MUST BE WONDERING WHAT IS SO SPEACIAL ABOUT IT THAT I CALL IT THAT WAY.WELL THE ANSWER LIES AHEAD AND TRULY ITS NOTHING LESS THAN A MAGIC.

THE FOUTH GENERATION TECHNOLOGY,IS THE LATEST AND AN ULTRA-FAST TECHNOLOPGY.IT IS GETTING MORE AND MORE ATTENTION EVEN THOUGH THE PROCESS IS IN ITS INITIAL STAGES.THIS TECHNOLOGY CAN PROVIDE US WITH A VERY SPEEDY WIRELESS INTERNET ACCESS OF 1GBPS DATA TRANSFER RATE TO STATIONARY USERS AND 100MBPS TO MOBILE USERS.

MAGIC=MOBILE MULTIMEDIA,ANYTIME ANYWHERE,GLOBAL MOBILITY SUPPORT,INTEGRATED WIRELESS SOLUTION,CUSTOMISED PERSONALIZED SERVICES.

THE ROOT OF 4G PASSED THROUGH STAGES OF 1G WHICH WAS EARLIER USED IN TELEPHONE COMMUNICATION.LATER IT WAS REPLACED BY 2G WHICH WAS MAINLY USED FOR VOICE COMMUNICATION AND PROVIDED LIMITED DATA TRANSFER.LATER CAME 3 G TECHNOLOGY WHICH PROVIDED HIGHER QUALITY VOICE CHANNELS AS WELL AS BROADBAND DATA CAPABILITIES OF UPTO 2MBPS DATA TRANSFER RATE TO STATIONARY USERS AND MINIMUM 384KBPS TO MOBILE USERS.

4G TECHNOLOGY WILL HAVE BROADER BANDWIDTH,HIGHER DATA TRANSFER RATE,AND QUICKER AND MOOTHER HANDOFF.IT WILL BE FULLY IPV6(INTERNET WIRELES PROTOCOL VERSION 6)BASED WIRELESS INTERNET.

4G WILL BE ABLE TO SUPPORT INTERACTIVE SERVICES LIKE VIDEO CONFERENCING(WITH MORE THAN 2 SITES SIMULTANEOUSLY),WIRELESS INTERNET,ETC.

4G MAKES USE OF IMPROVED ACCESS TECHNOLOGIES LIKE OFDM(ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING) AND MC-CDMA(MULTI CARRIER CDMA.4G IS ALSO CAPABLE OF USING MULTIPLE INPUT/MULTIPLE OUTPUT TECHNOLOGY(MIMO),WHICH IS USED TO OPTIMIZE THE DATA SPEED AND REDUCE THE ERROR IN THE NETWORK.

3G UTILIZED WIMAX(WORLDWIDE INTEROPERABILITY FOR MICROWAVE ACCESS) AND WIFI(WIRELESS FIDELITY) AS SEPARATE WIRELES TECHNOLOGIES,WHEREAS 4G IS EXPECTED TO MERGE THIS TWO TECHNOLOGIES,O THAT HUMAN BEINGS REMAIN INTACT WITH THE WIRELESS TECHNOLOGY INTENTONALLY AND UNINTENTIONALY.

WIMAX AND LTE(LONG TERM EVOLUTION)ARE TWO 4G CELLULAR BROADBAND NETWORKS.

ADVANTAGES OF 4G TECHNOLOGY

v  FASTER DOWNLOADING AND UPLOADING

v  MORE RELIABILITY IN DATA TRANSFER

v  MORE AFFORDABLE COMMUNICATION DEVICES

v  TV,INTERNET,PHONE,RADIO ALL SENSOR REACHABLE THROUGH MOBILE.

v  IT IS EXPECTED TO PROVIDE FACILITY SUCH AS IP TELEPHONY,ULTRA BROADBAND INTERNET ACCESS,3D GAMING SERVICE,AND HDTV STEAMED MULTIMEDIA

ITS ONLY DISADVANTAGES ARE IT IS EXPENSIVE,INVASION OF PRIVACY,AND BREACH OF SECURITY.

THUS,4G SURELY A MAGIC TO WHICH WE CAN LOOK FORWARD FOR.IT IS AVAILABLE IN COUNTRIES LIKE CHINA,CANADA,USA,SINGAPORE.
