18. Making QoE data available within industry
ETSI Guide
Web-based system

24. Please visit the web-based system & provide your feedback!
Conclusions
Service developers want end-user data
Much data not available
Tutorial support required
Standardisation bodies well positioned to disseminate QoE data
ETSI STF284
Please visit the web-based system & provide your feedback!
