1. The transition to LTE, the role of policy & control.Policy Control, Amsterdam, Netherlands, 5th April 2011. Dr. Kim Kyllesbech Larsen, Technology EconomicsTechnology, Deutsche Telekom.
2. 2 Uncontrolled data growth ... Smartphone traffic has exploded over last 2 years. Ă7 Smartphone indicators Data signaling Ă6 Smartphones Ă4 Throughput Ă5 Volume December 2008 to December 2010 Kim Kyllesbech Larsen, Policy Control April 5th, 2011, Amsterdam.
3. 3 Uncontrolled data growth...Will accelerate spectrum shortage. The 3G traffic jam! 3G capacity crunch. Re-farming spectrum. New spectrum demand. Empty 2G roads - in time? Re-farming GSM! HSPA+ versus LTE ? Technology timing! Kim Kyllesbech Larsen, Policy Control April 5th, 2011, Amsterdam.
4. 4 Uncontrolled data growth ... Will it lead to the End of Profitability? Revenue Positive FCF Negative Flat price plans and uncontrolled traffic growth will accelerate the road to The End. Kim Kyllesbech Larsen, Policy Control April 5th, 2011, Amsterdam.

32. 15 Summary.What we need to be passionate about. We cannot wait for LTE to implement intelligent traffic management. Apps-based policy, charging & control needs (more) consideration. Optimized traffic growth means controlled profitability. Kim Kyllesbech Larsen, Policy Control April 5th, 2011, Amsterdam.
