  1. 1. Regulation of NGA in Austria Kurt Reichinger Austrian Regulatory Authority for Telecommunications and Broadcasting The opinions expressed in this presentation are the personal view of the author and do not prejudge decisions of the Austrian regulatory authorities.
  2. 2. Agenda <ul><li>The regulator’s dilemma </li></ul><ul><ul><li>Life between hard-core SMP and soft law regulation </li></ul></ul><ul><li>The Austrian Unbundling market as an example </li></ul><ul><ul><li>From the ladder of investment concept to accepted products on the market </li></ul></ul><ul><li>Virtual unbundling </li></ul><ul><ul><li>New universal wholesale product … or just one remedy more on the list? </li></ul></ul>
  3. 3. The regulator‘s dilemma
  4. 4. It‘s not about incumbent bashing … <ul><li>Hard-core SMP regulation </li></ul><ul><ul><li>Market analysis procedure </li></ul></ul><ul><ul><ul><li>Definition of relevant markets  Analysis of competitive situation  Occurrence of significant market power (?)  Imposition of appropriate remedies </li></ul></ul></ul><ul><ul><li>Regulation often means definition of general conditions or a framework </li></ul></ul><ul><ul><ul><li>Regulation is more difficult in unknown waters </li></ul></ul></ul><ul><ul><ul><li>Regulation as an ex ante or ex post procedure </li></ul></ul></ul><ul><li>Soft law regulation </li></ul><ul><ul><li>EC recommendations, e.g. regarding NGA regulation </li></ul></ul><ul><ul><li>EC general strategies like the Digital Agenda </li></ul></ul><ul><ul><li>BEREC common positions </li></ul></ul><ul><ul><li>National topics </li></ul></ul>
  5. 5. Three tasks … not always easy to fulfil <ul><li>Safeguarding competition </li></ul><ul><ul><li>Mandating appropriate wholesale products (remedies) from SMP operator </li></ul></ul><ul><ul><li>Incentivising OLOs climbing the ladder of investment </li></ul></ul><ul><ul><li>Allowing sufficient margin for alternative and SMP operator </li></ul></ul><ul><li>Promoting innovation </li></ul><ul><ul><li>Promoting innovation from incumbent operator </li></ul></ul><ul><ul><li>Promoting innovation from alternative operators </li></ul></ul><ul><li>Incentivising investment </li></ul><ul><ul><li>Making investment scenarios attractive while safeguarding competition </li></ul></ul><ul><ul><li>But: Investors usually want return not regulation </li></ul></ul>
  6. 6. The Austrian unbundling market … as an example
  7. 7. Market definition and analysis <ul><li>Austrian definition of market 4 (“access to physical network infrastructure”) </li></ul><ul><ul><li>Included: Metallic loops only (!!) </li></ul></ul><ul><ul><li>Not included: Fibre, cable, mobile technologies </li></ul></ul><ul><ul><li>Included as ancillary service: Access to ducts and dark fibre, co-location, … </li></ul></ul><ul><li>Results of Austrian market analysis </li></ul><ul><ul><li>Copper access network of A1 Telekom Austria is „bottleneck resource“ </li></ul></ul><ul><ul><li>100% market share of A1 Telekom Austria </li></ul></ul><ul><ul><li>(Possible) disadvantages for alternative operators – also for broadband roll-out </li></ul></ul><ul><ul><li>A1 Telekom Austria has significant market power </li></ul></ul><ul><li>Now, what remedies to choose? </li></ul>
