WiMAX

WORLDWIDE INTEROPERABILITY FOR MICROWAVE ACCESS

PRESENTED BY:Akshay N MAhajan

WIRELESS TECHNOLOGIES ARE BECOMING MORE AND MORE POPULAR WITH GLOBALISATION

INTERNET IS BECOMING THE NEXT NECESSITY AFTER “THE MOBILE REVOLUTION”

THE WORLD TODAY

WAYS OF INTERNET ACCESS

• DIAL-UP

• BROADBAND

• Wi-Fi

PROBLEMS

DIAL-UP SLOW SPEEDBROADBAND EXPENSIVEWi-Fi SPARSE COVERAGE

KEY ELEMENTS OF WiMAX TECHNOLOGY

• LOW COST• WIDE COVERAGE• HIGHER CAPACITY

IEEE 802.16 SPECIFICATIONS:

• RANGE 30 MILE (50 KM) RADIUS FROM BASE STATION

• SPEED 70 Mbps

• LINE-OF-SIGHT NOT NEEDED BETWEEN USER AND BASE-STATION

• FREQUENCY BANDS 2 TO 11 GHz AND 10 TO 66 GHz

GOVERNMENT SECURITY

• WiMAX RECEPTORS RECEIVE FROM MULTIPLE TRANSMITTING TOWERS

• DESTRUCTION OF A TOWER BY TERRORIST ATTACK OR ANY CALAMITY WOULD NOT AFFECT CRUCIAL COMMUNICATION

NETWORK COMPARISION

PAN – PERSONAL AREA NETWORKEG. BLUETOOTH

LAN – LOCAL AREA NETWORKEG. Wi-Fi

MAN – METROPOLITAN AREA NETWORK

EG. WiMAX

IEEE STANDARD AND RANGE

WiMAX RANGE 8000 SQ. KMS

WiMAX APPLICATIONS

• 24 X 7 INTERNET ACCESS

• Wi-Fi ROUTERS CAN BE CONNECTED TO WiMAX

• VoIP (VOICE OVER INTERNET PROTOCOL)

• LAST MILE INTERNET CONNECTIVITY

VoIP SHARE OF INERNATIONAL TRAFFIC

•THE GRAPH SHOWS CLEAR INCREASE IN THE VoIP SERVICES

VoIP AND INDIA

WHY INDIA NEEDS WiMAX

• ONLY 50% OF INDIAN POPULATION HAS RESIDENTIAL INTERNET ACCESS

• THE REST RELY ON THE 9000+ CYBER CAFÉ’S

• 14% OF INDIA’S VILLAGES DO NOT HAVE A PUBLIC TELEPHONE

INDIA PREFERS WIRELESS TECHNOLOGIES

• CELLULAR PHONES REVOLUTIONISED TELEPHONY IN INDIA

• CELLULAR PHONE MARKET GREW 159% LAST YEAR

• INDIA ADDS APPROX. 1.7MILLION NEW CELLPHONE SUBSCRIBERS EVERY MONTH

THE IT REQUIREMENT

• INDIA BECOMING A MAJOR GLOBAL IT HUB

• BROADBAND INTERNET CONNECTIVITY A MUST

• MORE INTERNATIONAL COMPANIES WILL BE DRAWN IF BETTER NETWORKING FACILITIES PROVIDED

INDIA – LAND OF DIVERSE GEOGRAPHIES

• LAYING OUT WIRES CAN BE DIFFICULT IN SOME HILLY AREAS

• ISLANDS TOO POSE THE SAME PROBLEM

•WiMAX HAS SIMILAR OPERATION LIKE MOBILE TOWERS

DISADVANTAGES

THE INITIAL INFRASTRUCTURE AND INVESTMENT

PLUS POINT OF WiMAX

MOBILE TOWERS CAN ALSO BE USED FOR TRANSMISSION AS MOBILE AND WiMAX FREQUENCIES DO NOT INTERFERE EACH OTHER

OPPORTUNITIES IN INDIA

• 1.1 BILLION PEOPLE = WORLD’S LARGEST DEMOCRACY• 300 MILLION PEOPLE = WORLD’S LARGEST MIDDLE CLASS

• BROADBAND AND INTERNET GROWTH A PRIORITY – GOVERNMENT OF INDIA HAS SET MINIMUM GOAL OF 20MILLION BROADBAND SUBSCRIBERS BY 2010

E-GOVERNENCE

• E-SEVA ANDHRA PRADESH• GRAMDOOT RAJASTHAN

GUJARATKARNATAKAMADHYA PRADESHKERELAHAVE INITIATED SEVERAL E-GOVERNANCE PROJECTS

EDUCATION

• DISTANCE LEARNING

• ONLINE LIBRARIES

• VIDEO CONFERENCE LECTURES IN RURAL AREAS

AGRICULTURE & HEALTH

• PREVENT CROP DISEASES BY PERIODICALLY SENDING HIGH RESOLUTION IMAGES TO AGRICULTURAL EXPERTS

• DOCTORS CAN VIDEO CONFERENCE WITH PATIENTS TO DISCUSS SYMPTOMS & TREAT DISEASES

VISION 2020 : INDIA DEVELOPED

• WiMAX MORE EFFECTIVE ON RURAL INDIA ALONG-WITH THE URBAN

• WiMAX FACILITATES E-COMMERCE

• WiMAX = HIGH SPEED + WIDE COVERAGE + COST

EFFECTIVE

VISION 2020 : INDIA DEVELOPED

DEVELOPMENT OF RURAL INDIA IS ULTIMATELY THE DEVELOPMENT OF INDIA
