FOR MICROWAVE ACCESS
PRESENTED BY:
Akshay N MAhajan

2. WIRELESS TECHNOLOGIES ARE
BECOMING MORE AND MORE
POPULAR WITH GLOBALISATION
INTERNET IS BECOMING THE NEXT
NECESSITY AFTER “THE MOBILE
REVOLUTION”
THE WORLD TODAY

3. WAYS OF INTERNET ACCESS
• DIAL-UP
• BROADBAND
• Wi-Fi

4. PROBLEMS
DIAL-UP  SLOW SPEED
BROADBAND  EXPENSIVE
Wi-Fi  SPARSE COVERAGE

5. KEY ELEMENTS OF WiMAX
TECHNOLOGY
• LOW COST
• WIDE COVERAGE
• HIGHER CAPACITY

7. 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

8. GOVERNMENT SECURITY
• WiMAX RECEPTORS RECEIVE
FROM MULTIPLE
TRANSMITTING TOWERS
• DESTRUCTION OF A TOWER
BY TERRORIST ATTACK OR
ANY CALAMITY WOULD NOT
AFFECT CRUCIAL
COMMUNICATION

9. NETWORK COMPARISION
PAN – PERSONAL AREA NETWORK
EG. BLUETOOTH
LAN – LOCAL AREA NETWORK
EG. Wi-Fi
MAN – METROPOLITAN AREA
NETWORK
EG. WiMAX

10. IEEE STANDARD AND RANGE
WiMAX RANGE  8000 SQ. KMS

11. WiMAX APPLICATIONS
• 24 X 7 INTERNET ACCESS
• Wi-Fi ROUTERS CAN BE
CONNECTED TO WiMAX
• VoIP (VOICE OVER INTERNET
PROTOCOL)
• LAST MILE INTERNET
CONNECTIVITY

12. VoIP SHARE OF INERNATIONAL TRAFFIC
•THE GRAPH SHOWS CLEAR INCREASE IN THE
VoIP SERVICES

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

15. 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

16. 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

17. 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

18. 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

19. 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

20. E-GOVERNENCE
• E-SEVA  ANDHRA PRADESH
• GRAMDOOT  RAJASTHAN
GUJARAT
KARNATAKA
MADHYA PRADESH
KERELA
HAVE INITIATED SEVERAL E-
GOVERNANCE PROJECTS

RURAL INDIA ALONG-WITH
THE URBAN
• WiMAX FACILITATES
E-COMMERCE
• WiMAX = HIGH SPEED + WIDE
COVERAGE + COST
EFFECTIVE

24. VISION 2020 : INDIA DEVELOPED
DEVELOPMENT OF
RURAL INDIA IS
ULTIMATELY THE
