Voice over WiMAX Development Trends Voice over WiMAX Development Trends Presentation Transcript

  • Topics
    • Challenges and complexity
    • Customer perspective
    • Service provider perspective
    • 3G new breed of services
    • Solutions & protocols
  • The Challenge
    • Hybrid solutions of WiFi/WiMAX and 3G/GSM enabled devices - next step in Mobile Broadband evolution
    • From a consumer perspective, these technologies should operate seamlessly
    • This hybrid of technology convergence
      • Introduces new challenges
      • Requires knowledge of a wide range of technologies
    How can the customer use it? What about the user experience ?
  • The Complexity
    • Convergence
      • Access (XDSL, Cable, Wi-Fi, WiMAX, 3G, …)
      • Networks (CS, PS, radio)
      • Device (per technology vs. cross technology)
      • Service (Service per network vs. unified services)
    • Technologies ( DMH, UMA, FMC, IMS)
    • Mobility (network independent services)
    • Coverage (roaming, handover, handoffs)
    • Usability (How can customers use it?)
    • Services (Quad play – voice, video, data, mobile)
  • The Broad Picture - WiMax Convergence The real developer challenge… WiMAX Packet Cable WiFi 2/2.XG PSTN/ DECT FTTx PSTN WCDMA CDMA2K UMA FMC DMH IMS
  • Customer objective: Preserve existing services
    • Telephony
    • Emergency call
    • TTY
    • SMS, MMS
    • Data/ Internet
    • Location Service
    • Supplementary Services (e.g. Caller ID, one voicemail, 3-way conference)
