    1. “Where WiMAX Fits - Mobile WiMAX at various bands V.K.Arya DDG (N), TEC, DOT

    2. 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

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

    6. Bandwidth Requirement

    7. WiMAX Profiles

    9. 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)

    11. 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
