1 Digital Dividend Overcoming obstacles Eric Fournier Director Spectrum Planning and International Affairs Agence Nationale des Fréquences

2 Three inter-related objectives Digital Dividend is a result of the analogue switch-off and digital switch-over. All three processes have to be seen in conjunction Example of France: Law of 5 th March 2007 –Extension of digital TV : Coverage of 95% of the population Additional multiplex (HDTV, mobile TV, bonus channels) from the 5 used for introduction of DTV –Analogue switch-off Switch off before 30 November 2011 Final plan to be decided by the Prime Minister Detailed plan for progressive switch off (area per area) should be published by the broadcasting authority (CSA) 9 month before its realization –Digital dividend National scheme for the reutilization of frequencies made free by the analogue switch off to be decided by the Prime minister after consultation of an ad-hoc parliamentary commission on the digital dividend The majority of the digital dividend is to be attributed to broadcasting

3 Analogue switch off and digital switch-over For countries like France where fixed reception remains the main TV reception mode, simulcast was necessary In a transition phase, it is necessary to ensure compatibility between –digital (inc. new services) –and analogue TV The final plan is the situation after the end of analogue : –It has to account for broadcasting and mobile dividend –It is progressively defined and achieved region by region During transition and at switch-over, it is necessary to coordinate with the neighbours

4 Three inter-related objectives Extension of DTV Arrêt de lanalogique Transition planFinal plan Digital Dividend for broadcasting 21/12/ % of population 95% of population Cambios de frecuencias Refarming of analogue Digital dividend for mobile Switchover

5 Current transition multiplex arrangement in France 18 free + 10 pay TV + 5 HDTV

6 Current TV reception modes TV Access (considering only primary TV set) % of households in 2008Evolution over a year DTT30.1%+14.3 points Digital satellite14.1%+2.5 points ADSL TV10.5%+5.1 points Digital Cable (pay-TV) 5.5%+0.8 point Exclusively analogue terrestrial access 28.5%-16.9 points Analogue cable (free and pay TV) 8.5%-0.7 point

7 Plan France-Numérique 2012 Plan published by the government in October Prime Minister decisions published 23 rd December Switch-over –First experience of switch-over in 2009 : Coulommiers, Kaysersberg, Cherbourg –General process for switch over (information, assistance …) –Starting simultaneously from East (Alsace, Lorraine, Champagne, Franche-Comté…) and West (Basse-Normandie, Pays de la Loire, Bretagne …) Digital dividend – MHz allocated to mobile service from 30 November 2011 ( previously used by Defence) –Objective of 11 multiplex for DTV and 2 multiplex for mobile TV in the band MHz –Negociation mandate to the ANFR for addressing the issue with neighbouring countries

8 What could we learn from our experience ? It is possible to densify the use of the UHF band : –For analogue/digital simulcast –For increasing broadcast services (mobile TV, HDTV, more programmes) –For digital dividend Two critical elements : –Timing –Cross-border coordination

9 Authorization process The last part of the UMTS core band (3 blocs of 2x5 MHz) will be allocated soon (beauty contest starting next month) Current public consultation covering both authorization process for : – MHz – MHz Auction envisaged Refarming necessary for both bands : –Defence Point to Point links at 2.6 GHz (>700 links) –New programme for tactical defence communication system initially planned in the band MHz

10 Cross-border coordination Negotiation for the transition plan quasi-finalized with French neighbours Three objectives for the final Plan : –Reconstituting broadcasting networks below 790 MHz –Adding new multiplex (today situation is 6/7 DTV multiplex + 5 analogue in simulcast) –But also protecting the sub-band MHz (in particular MHz) General principle is equitable access of spectrum, independently from the services Each neighbour has different objectives (use of the sub-band, broadcasting usage, timing)

11 Interference risk at the border

12 CEPT Harmonisation After WRC-07, CEPT has confirmed that the band MHz was THE sub-band For economies of scale, it is essential to agree on technical conditions applicable to this frequency band : –Channelling arrangement –Block edge mask ECC Decisions in 2009 would trigger the development of equipment for availability in 2012 Widespread use of the sub-band in the long term would be beneficial to all CEPT countries

13 Channelling arrangement Harmonised channelling arrangement will be FDD 2 x 30MHz Duplex gap of 11 MHz Block size in multiples of 5 MHz Reverse duplex direction. Guard band of 1 MHz with broadcasting

14 BEM technical conditions Technical conditions necessary for : –Coexistence between different operators –Coexistence with broadcasting below 790 MHz –Coexistence with systems which will be used in the centre gap (e.g. radiomicrophones) Consisting in block edge mask and eirp limitations

15 Protection of TV below 790 MHz Risk of local interference to TV reception around base stations The risk is dependent on TV receiver performance Adjacent channel protection (channel 60) and, in the immediate vicinity, possible overloading effect Measures to ensure compatibility (additional filtering, antenna pointing …) can only be taken at local level Discussions in France : –Extent of responsibility for mobile operators –Procedure to ensure that interference will be treated –Technical guidance to assess risk of interference and to mitigate interference

16 Coordination ARNS in Russia vs Mobile in other countries Protection of ARNS from mobile service is on the basis of RR 9.21 procedure except for those countries which had mobile allocation before WRC-07 : –Agreement is to be sought from ARNS countries which may be affected –Lack of technical elements for determining the affected ARNS administrations –Any objection is to be based on existing assignment –Review at WRC-11 under agenda item 1.17 From a technical standpoint, the most difficult issue is the protection of airborne ARNS receiver. However, existing assignments are very limited (only few MHz) However, from a regulatory standpoint both « ARNS » administration and « mobile » administrations may block new assignments (ARNS or mobile) based on broadcasting rights (GE- 06) !

17 Coordination ARNS in Russia vs Mobile in other countries (2) Status quo may be beneficial today for Russia but is not a long-term solution : –Russia should have the possibility to evolve ARNS usage and/or to plan for digital dividend –Neighbouring countries should have the possibility to deploy mobile service instead of broadcast In the context of 1.17 a compromise solution has to be found

18 THANKS ! Any question ?
