Wi Max Updated Presentation Transcript

  • 1. Enabling Deployments through Standards & Certification Margaret LaBrecque WiMAX President ma [email_address]
  • 2. What is IEEE 802.16* / WiMAX* / ETSI HiperMAN*?
    • ETSI HiperMAN and IEEE 802.16 represent a GLOBAL standard for a wireless broadband access
      • akin to Cable, DSL and Ex-level services
    • Designed from the ground up for outdoor, long range, carrier class applications
      • High throughput, non line of sight propagation, scalability for up to 1000's of users, QoS
    • Supports both licensed and license-exempt spectrum
    • Applicable in many markets – from dense urban environments to rural areas
      • Where there is no existing or poor wired infrastructure
    • IEEE 802.16e extension enables nomadic capabilities for laptops
      • Broadband connectivity beyond hot spots
    • Wi-Fi and WiMAX are complementary
    • WiMAX* is to 802.16 as Wi-Fi* is to 802.11
    * Other brands and trademarks are property of their respective owners
  • 3. Global Wireless Standards IEEE 802.15 Bluetooth WAN MAN LAN PAN ETSI HiperPAN IEEE 802.11 WirelessLAN ETSI HiperLAN IEEE 802.16 WirelessMAN ETSI HiperMAN & HIPERACCESS IEEE 802.20 (proposed) 3GPP, EDGE (GSM)
  • 4. Wireless Platforms Fixed Licensed and Unlicensed E1/ T1 & DSL level service Portable Licensed and Unlicensed Consumer DSL level service Mobile Licensed Wideband Data Rates 802.16 HiperMAN Enterprise / Backhaul 802.16 HiperMAN Residential access Nomadic Cellular Wideband 2.5G, 3G Destination based 802.11 Hot Spots 802.16e
  • 5. What is WiMAX?
    • Ensure interoperability of IEEE 802.16* and other interoperable (ETSI HiperMAN*) systems
      • Equivalent in purpose to Wi-Fi Alliance for 802.11
    • Develop Conformance Test Specifications
      • Two year, multi-company process to develop test suites
        • Based upon ISO/IEC 9646 processes
      • System Profiles correspond to market-driven usage modes
        • e.g., license exempt at 5.x GHz, licensed at 3.5 GHz, etc.
    • Set up certification labs for testing
    • Host interoperability events
      • Conformance does not equal Interoperability
      • Provide WiMAX-Certified stamp of approval
    * Trademarks or servicemarks are the property of their respective owners. WiMAX members represent over 75% of current 2-11 GHz BWA equipment sales!
  • 6. Why has BWA not taken off?
    • Pre-Standard:
    • Proprietary, vertical solutions
    • No volume silicon market
    Service Providers System Design & Architecture Custom MAC Custom Radio Custom, 802.11 or DOCSIS PHY Network Software System Integration Equipment Mfrs Focus
    • Post-Standard:
    • Equipment interoperability
    • Economies of scale
    • Superior price/performance
    Service Providers Equipment Manufacturers Volume Integrated MAC/PHY Silicon Solutions Volume Radio Supplier Network Mgmt Software Supplier System Integrator Equipment Mfrs Focus* * Varies by equipment mfr. Some will still do their own S/W and SI.
  • 7. Enable Standards & Interoperability 1980s 1990s 2000 Volume Ethernet 2010
    • Formula :
    • Existing proprietary technology & market
    • Standards adoption
    • Low cost manufacturing through economies of scale
    • Wireless: available spectrum
    IEEE: The Path to Volume Economics *Other names and brands may be claimed as the property of others.

  • 11. 802.16 and HiperMAN: Designed from Ground Up for the Outdoors
    • Higher throughput at longer ranges (up to 50 km)
      • Better bits/second/Hz at longer ranges
    • Scalable system capacity
      • Easy addition of channels maximizes cell capacity
      • Flexible channel bandwidths accommodate allocations for both licensed and unlicensed spectrum
    • Coverage
      • Standards-based approach to advanced techniques (mesh, beam-forming, MIMO) to improve non-line-of-sight performance
    • Quality of Service
      • Connection oriented MAC supports voice and video
      • Differentiated service levels: E1/T1 for business; best effort for residential
    • Cost & Investment Risk
      • Interoperable equipment lets operators purchase equipment from more than one vendor – WiMAX-Certified
      • A stable, standards-based platform improves OpEx by sparking innovation at the network management layer, antenna layer & elsewhere
