Agenda
  • Introduction
  • WiMAX Applications
  • Bandwidth requirement
  • Global Spectrum scenario for WiMAX
  • Global Harmonized bands Advantages
  • Where WiMAX Fits
  • Spectrum Availability for WiMAX in India
  • Conclusion

3
Introduction
  • The focus of this Conference is on
  • Affordable mobile broadband access mobile VoIP
    - using WiMAX Technology.

4
IEEE 802.16 Standard Evolution
  • Dec 2001- 802.16 ratified for wireless
    metropolitan areas network (MAN) in 10-66 GHz
    frequency range (LOS)
  • Jan 2003 - 802.16a extension for sub-11 GHz
    (2-11GHz NLOS)
  • June 2004 - 802.16d 2004 standard for Fixed
    WiMAX was ratified.
  • Dec 2005 - 802.16e approved now known as
    802.16e-2005 for Mobile WiMAX

WiMAX Applications
  • Applications
  • Broadband Internet Access
  • Personal (Mobile) Broadband
  • VoIP
  • Video
  • E-education
  • Public Safety
  • E-Governance
  • Entertainment and
  • Others

Global Spectrum scenario for WiMAX
Western Europe 3.5 GHz
China 3.5GHz
Canada 2.3,2.5, 3.5 GHz
Korea 2.3GHz
US 2.3,2.5 GHz
Eastern Europe 2.5,3.xGHz
SEA 3.5 GHz 2.5 GHz 2.3 GHz
Japan 2.5 GHz
Middle East 3.5,5.8 GHz
Africa 2.5GHz
Latin America 3.5 GHZ 2.5 GHz
India 3.3 GHz
Australia 2.3, 2.5 GHz

Global Harmonized bands - Advantages
  • Benefits of economies of scale - lower cost of
    equipment.
  • Interoperability and roaming of equipment and
    terminals Globally.
  • Success of WiFi and its world wide adoption is
    credited to the globally unified spectrum
    assignment in the 2.4 GHz band. The success of
    WiFi can be repeated in WiMAX by assigning
    globally harmonized spectrum bands.

10
Where WiMAX Fits
  • 2.3 - 2.4 GHz ( used in Aus, Singapore, Korea,
    Malaysia, USA, Canada etc., - so wide Adoption
    and suitability for Mobile Application)
  • 2.5 - 2.69 GHz ( used in USA, Latin America,
    Japan, SEA and, part band in Europe)
  • 3.4 3.6 GHz (More suitable for fixed
    applications- used in many countries)

Bands Availability and status of Frequency
Allocation in India
12
Licensed Vs Unlicensed Bands
  • Licensed
  • Required for assuring QoS and service reliability
  • Generally preferred in heavily populated areas
  • Network scalability under control of operator
  • Operator predetermine impact of license fees on
    business case
  • Fewer operators means less crowding
  • Unlicensed
  • Unlicensed spectrum in rural areas means lower
    cost for the end customer
  • Fast roll outs no need to wait for the
    licensing process
  • Counters the lengthy licensing process

13
Conclusion
  • 2.3-2.4 GHz Band
  • Presently, this band is used by several
    organizations for point-to-point and
    point-to-multipoint microwave links, spread all
    over the country.
  • Re-location of such links would be necessary to
    make available spectrum for WiMax in this band.

14
Conclusion
  • 2.5 2.69 GHz band (190MHz)
  • Availability of adequate spectrum for WiMAX is
    constrained due to existing usages, especially by
    the INSAT based satellite operations.
  • Release of a part of the spectrum in this band
    may be explored by mutual consent.

15
Conclusion
  • 3.4 - 3.6 GHz band
  • Internationally, the frequency band 3.4-3.6GHz is
    used for WiMAX.
  • In India, availability of spectrum for WiMAX, in
    this band, is constrained due to use of lower
    extended C-band (3.4-3.7 GHz) by existing
    operational INSAT system.
  • Discussions with Department of Space is in
    progress for release/ sharing part of 3.4-3.6
    GHz Band.
