  3. 2004: Going from Analogue to Digital Rationale: • Broadcasting will become a full part of modern integrated media systems (“all digital”) • New possibilities for value creation (mobile reception of TV) • More efficient use of scarce frequency resources (more channels) • Lower transmission cost Marc Le Devendec (ECO)

  4. RRC-04 Regional Radio Conference 2004 (RRC-04) • Identify/solve the technical issues • Fixed / Mobile reception • Coordination at the border • Transition period (analog and digital) • Definition of requirements for each countries Marc Le Devendec (ECO)

  5. RRC-06 Regional Radio Conference 2006 (RRC-06): Finalisation of the work and initiation of next steps... • Adoption of a Digital TV Plan • Procedures to modify the Plan • Transition period end in 2015 • Provisions to allow the possibility to use the boradcasting entries in the Plan for other use (Mobile) Marc Le Devendec (ECO)

  6. WRC-07 • Digital technology for TV allows to use less spectrum: Digital Dividend (DD) • Possibility for other services • Allocation of the frequency range 790 – 862 MHz to the Mobile Service • Call for studies to assess the compatibility between Mobile and Broadcast Services / Other Services

  7. 2011: Overview • 470 – 790 MHz: • TV • PMSE / Other Services • Studies relating to the white spaces / cognitive radio • 790 – 862 MHz: • Available for Mobile Service (regulations) • Aeronautical • PMSE possibly in center gap 823 - 832 MHz
