  3. An overview of the available spectrum • Analogue TV uses 368MHz in UHF band (470-862MHz) • Proposals looking at best options for: • 256MHz reserved for digital terrestrial TV (DTT) • 112MHz freed up by DSO ( plus 2 x 8MHz freed from aeronautical radar and radio astronomy) – in total 128MHz of cleared spectrum • Also use of white space in DTT network - “interleaved spectrum”.

  5. International and European developments • World Radiocommunication Conference 2007 • Primary mobile allocation for 790-862 MHz in more Region 1 countries from 2009 • Primary mobile application for 790-862 MHz in all Region 1 countries from 2015 • European Commission Communication on digital dividend • Proposed identification of common bands for clusters of similar networks • Did not address precise locations of those bands • CEPT band plan • 790-862 MHz

  6. costs v benefits to align with European harmonisation • Net incremental benefit of clearing channels 61,62 and 69 lies within a range of £2 - £3bn (NPV over 20 year period) • Benefits of clearing 800MHz band include: • Lower equipment costs • Fewer restrictions on spectrum use • More valuable spectrum made available • Increased competition • The costs • Less cleared spectrum available for DTT • Implementation costs • direct costs of moving existing DTT and PMSE use out of channels 61, 62 and 69 • Minimising impact on consumers and citizens £bn Key: DTT costs PMSE cost 3 2 1 0 Costs Benefits

  8. Statements on Cleared Spectrum • Publication of Digital Britain Final Report on 16/06/09 see http://www.culture.gov.uk/images/publications/digitalbritain-finalreport-jun09.pdf ; • Statement on “Digital dividend: clearing the 800 MHz band” http://www.ofcom.org.uk/radiocomms/ddr/published 30/06/09 contains proposals for: • clearing 790-862 MHz (channels 61 to 69) of existing and previously planned users and align the upper band of the UK’s digital dividend with CEPT Band Plan. • how we intend to move those existing and previously planned users – digital terrestrial television (DTT) and programme-making and special events (PMSE) – from channels 61, 62 and 69 to equivalent spectrum elsewhere in the Digital Dividend. • Our next steps including some information on how we intend to re plan the lower Digital Dividend to relocate the effected upper band DTT and PMSE services.

  10. Cleared spectrum: harmonised technical conditions • Response to EC Mandate split into 3 parts by CEPT • Development of Protection Criteria for Broadcast and PMSE services • Development of Least Restrictive Technical conditions for ECS • Development of Appropriate Channel Plan (s) for ECS • Draft Response to the EC Mandate approved at the ECC meeting (June 09) • TG4 developed Protection Criteria CEPT Reports 23,24,25,29,32 & ECC Report 138 • PT1 developed Channel Plan(s) CEPT Report 31 (also see ECC Decision (09) EE) • SE42 developed Least Restrictive Technical Conditions (BEM) CEPT Report 30 • Status in July 09 • CEPT Report 30 is currently open for public consultation www.ero.dk . • BEMs for ECN both FDD/TDD D/L and FDD/TDD U/L • BEMs for Low power services in the FDD Duplex Gap • BEMs for PMSE services in the TDD guard band • A number of CEPT Countries have indicated they intend to clear 790 – 862 MHz.

  11. Introduction to BEMs • A BEM is an emission mask that is defined, as a function of frequency, relative to the edge of a block of spectrum that is licensed to an operator. It consists of in-block and out-of-block components which specify the permitted emission levels over frequencies inside and outside the licensed block of spectrum respectively. The out-of-block component of the BEM itself consists of a baseline level and, where applicable, intermediate (transition) levels which describe the transition from the in-block level to the baseline level as a function of frequency. • BEMs shall be applied as an essential component of the technical conditions necessary to ensure coexistence between services at a national level. However, it should be understood that the derived BEMs do not provide full protection of victim services and additional mitigation techniques and/or a protection clause may need to be applied in order to resolve any remaining cases of interference.

  12. Introduction to BEMs • The BEMs for TDD devices are derived here with the assumption that TDD networks in adjacent frequencies are unsynchronised. Less stringent BEM limits may be used (subject to agreement by affected parties) if the TDD networks are synchronised. • The BEMs are presented as upper limits on the mean EIRP. These are defined as the maximum EIRP value measured or integrated by an RMS detector over the specified measurement bandwidth, and over an averaging time interval of a signal burst duration. • In general, and unless stated otherwise, the BEM levels correspond to the power radiated by the relevant device irrespective of the number of transmit antennas, except for the transition requirements which are specified per antenna.

  13. Outline of BEMs in CEPT Report 30 See the hidden slides in this presentation or CEPT Report 30 for the actual agreed BEMs for the following services : • FDD base stations • FDD terminal stations • TDD base stations • TDD terminal stations • Low-power services in the duplex gap of TDD band-plan • PMSE services in the guard-band of the TDD band-plan

  14. EC Consultation on Digital Dividend • The European Commission have issued a consultation on the digital dividend which was published last week (10 July). It emphasises the potential benefit of an appropriate co-ordinated European approach (which is estimated to provide an additional EUR 20-50 billion benefit between now and 2015 above individual national plans). The key points of this consultation are: • The Commission has indicated its intention to come forward with proposals later this year which will then need to be discussed with the European Parliament and the Council (Member States). The actions currently under consideration include: • Ensuring the availability of a compression standard at least as efficient as MPEG 4 on all DTT receivers sold after 1 Jan 2012; • Setting standards for the ability of digital TV receivers to resist interference; • Promoting co-operation between Member States; • Adopting a common position across the EU on potential use of white space; • Encouraging’ Member States to sign the WRC footnote covering clearance of 790-862 at next WRC. • In addition there are two more immediate actions proposed; • Proposal for an EC Decision which would not necessarily mandate clearance of 790-862 but if a MS does, would require that it is done in accordance with the CEPT band plan. • Plan is that this could be agreed over the autumn (through RSC) and come into force early next year. • Request MS to reaffirm their commitment to the EU target date for switchover (Jan 2012)

  15. Next Steps • Planning how to integrate new DTT plans into UK DSO plans. (Jul 09 onwards) • Re-negotiating GE06 agreements with neighbouring countries where necessary. Jul 09 onwards) • Prepare UK comments for public consultation for CEPT Report 30 and EC Decision (09) EE. (July – Aug 09) • Depending on the responses to the CEPT consultation, provide inputs to the next SE42 and ECC meetings. ( Aug – Oct 09) • Participate in EU Radio Spectrum Committee discussions on CEPT response to mandate – (Oct 09 onwards) • Participate in EU RSC discussions on CEPT response to mandate and possible EC Decision (autumn 09) • Ofcom are continuing to undertake a raft of work on ensuring that both the DTT and PMSE migration to the new channels is as smooth as possible, and we will be consulting on our implementation plans (separately for DTT and PMSE) in the late Autumn. (July 09 onwards)
