Introduction Convergence start with Technology Intuition Case1 Case2 Example1 Example2 Observations • Technology itself is neutral • Competition based on the laws of physics • Competition based on the regulative acceptance (spectrum..) • Competition based on the adoption by standardization bodies • Competition based on the adoption by value systems • Competition based on the adoption of operators within value systems • Competition based on the adoption of the end users • Competition based on the inter-working • Competition based on the price ( cost ) of the primary service • Competition based on the innovation and re-use • Good Ideas and Technologies will be re-used Ref Rogers TKK/TIK 109.4300/TAV 2006
Introduction Consolidating, Converging, Diverging Intuition Case1 Case2 Example1 Example2 Observations • Technology is neutral • Technologies may be developed further forever • Value systems converge and merge and emerge, based on the factors that are much broader and deeper than just technologies • Regulation should be neutral for between value systems • Between value systems there is little need for compatibility anyway • Regulation should not be neutral inside each value system • Harmonization of technologies for each purpose is needed • Competition between technologies in the same value system does not provide added value for the end user but increases costs of the vendors and operators • Competition between operators and technologies (vendors) may increase innovation • Standardization is value system sensitive • Driven by people • Driven by companies • Driven by value system players TKK/TIK 109.4300/TAV 2006

Introduction Some Observations Intuition Case1 Case2 Example1 Example2 Observations • Traditional Internet and Mobile service will be available through many Value Systems, isolated “pipes” • Each value system includes internal and external competitive elements • Compatibility is crucial within each value system • Value systems gain and loose when merging together • Do not look at the symptoms only, Look at the deep structures • Value is created by Innovation but innovation leads to fragmentation • Value can be made better usable, utility is increased, by standardization • Harmonized solutions (technologies) add value only when directly visible to the end users • Unharmonized solutions (technologies) reduce value when applied within one value system • Unharmonized solutions (technologies) are natural in different value systems due to different regulative and end user requirements TKK/TIK 109.4300/TAV 2006
