Making qoe data available within industry

Making QoE data available within industry

ETSI Guide

Web-based system


Conclusions

Conclusions

  • Service developers want end-user data

  • Much data not available

  • Tutorial support required

  • Standardisation bodies well positioned to disseminate QoE data

    • ETSI STF284

    • http://portal.etsi.org/stfs/hf/STF284.asp
