Future spectrum sharing scenarios - Tim Miller, Plum consulting

  1. 1. Plum Consulting, London | +44 (0)20 7047 1919 | www.plumconsulting.co.uk Future spectrum sharing scenarios Tim Miller UK Spectrum Policy Forum, Cluster 2 9 July 2015
  2. 2. Agenda  Possible sharing  Plausible sharing  Public sector sharing  Projected sharing © Plum 2015 1
  3. 3. What is sharing?  More than one party using the same frequency ・ Separated by time or geography ・ Requires coordination between parties © Plum 2015 2 Absolute licences Multiple licences for the same spectrum in different regions LSA Defined protection and usage DSA Usage undefined, permissions set in real time Licence exempt No protection, requiring sensing and interference protocols
  4. 4. The need for sharing  Spectrum use needs to be more efficient ・ The number of spectrum using applications is growing ・ Many (but not all) spectrum using applications need more spectrum to cope with rising demand (for example mobile, PMSE) ・ There are spectrum sweet spots where demand for spectrum is likely to peak © Plum 2015 3 0 500 1,000 1,500 2,000 2,500 3,000 3,500 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025 2026 2027 PB per month Mobile data traffic projection
  5. 5. Existing sharing © Plum 2015 4 Defence MobileBroadcasting PMSE  The UK Wireless Telegraphy Act regime is favourable for sharing ・ It does not have the exclusive use issues that occur in some other countries ・ There is an issue on licensing of databases
  6. 6. More sharing could be done © Plum 2015 5 Defence MobileBroadcasting PMSE UtilitiesConsumer WiFi Space AeronauticalPPDR Other public sector users
  7. 7. Plausible sharing © Plum 2015 6
  8. 8. Successful sharing requires incentives © Plum 2015 7 • As far as possible incentives should align across incumbents and sharers • Market driven is better than imposition • No or wrong incentives = no effective sharing Ability to make viable investments Ability to coexist on a technical basis An adequate compensation mechanism Favourable regulatory requirements Political pressure
  9. 9. Different objectives – different solutions © Plum 2015 Source: Ofcom (adjusted) 8 High LSA Low Medium DSA Medium Low Licence exempt High Reducing barriers to access Increasing service range and quality
  10. 10. Balancing supply and demand © Plum 2015 9 Supply Demand Certainty Provide good quality Value for money Flexibility Maintain output CompensationFinancial Interference Duration Regulatory environment voluntary | transparent | enforceable
  11. 11. Public sector sharing © Plum 2015 10
  12. 12. Public sector sharing  In theory sharing could occur between any combination of incumbent and user ・ In reality some scenarios will be more likely than others ・ There is public sector spectrum that could be shared  But public sector spectrum users need to be: ・ Incentivised to share ・ Legally able to share © Plum 2015 11 Commercial Public Sharer Incumbent Commercial Public
  13. 13. Public sector issues  Is the Crown RSA process fit for purpose as a means to enable sharing of spectrum? ・ Can it cope with change of use on a short or long term basis?  Can public sector players who share spectrum be adequately compensated? ・ Most see this as an issue at the moment © Plum 2015 12 Agree LSA contract Issue new licence Adjust licence if needed Payment Payment Direct payment or reduced AIP Sharer Public sector user Ofcom Central government
  14. 14. Projected sharing © Plum 2015 13
  15. 15. Sharing in the long term © Plum 2015 14  The easy pickings have mostly gone ・ Spectrum clearance will become more costly  As the demand for spectrum increases, so will the value of spectrum ・ The willingness to pay for shared spectrum will increase  Long term economic trends drive towards more spectrum sharing ・ There will be a role for both LSA and DSA ・ Technology improvements may make sharing easier  The demand for shared spectrum will not just come from mobile ・ Other users will want access to shared spectrum Defence MobileBroadcasting PMSE UtilitiesConsumer WiFi Space AeronauticalPPDR Other public sector users
  16. 16. Issues to address Need to clarify the regulatory framework around sharing • Ofcom should clarify what sharing can currently be done (LSA?) Need to ensure the pubic sector can share spectrum • Government should deal with the regulatory and financial issues Need to encourage the market through transparency of supply and demand • Policy makers should make it easier for supply and demand to match © Plum 2015 15
