Pricing Models

All-you-can-eat data (M1, M5) Limited-cap data packages (M2 – M4) All-you-can-eat plans boost users’ consumption

Behavioral Shift

  • Fixed-line accesses (F1-F5) peaks in the evening
  • Limited data caps (M2-M4) peak in commute hours

Mobile users watch more during commutes

Speculative Content Pre-fetching

Pre-fetch at home Watch during commutes Speculative pre-fetching can save up to 50% of mobile traffic

Conclusion

User Experience Infrastructural Support Business Models

  • user engagement depends on the level of infrastructural support
  • … as well as on pricing models
  • and there is a lot potential for mobile content pre-fetching
