Stephen Temple - 5GIC - Dynamic Spectrum Expansion for 21 May SPF

  1. 1. Spectrum Policy Forum What is the problem I am trying to solve? Making a success of 5G for the 9 million people who live in Rural Britain with the aid of dynamic spectrum access Prof Stephen Temple CBE, 5G IC, University of Surrey
  2. 2. Band Area with spectrum waste* 3G at 2.1 GHz 87.5% 10 years after 3G auction 64% (Coverage 36%) 15 years after 3G auction 4G at 2.6 GHz 98% 5 years after 4G auction 5G at 3.6 GHz 5G at 3.6 GHz will be “capacity driven” thus urban focussed The raw ingredient for this 5G rural success is “spectrum waste” - Historic data suggest that a large geographic waste of 5G spectrum is likely to occur at 3.6 GHz Ofcom Data Industry Data These are very large numbers No coverage obligation to drive coverage down a common path * Spectrum waste is defined here as some unused spectrum perishing as a result of the spectrum not being employed to run services in that location.
  3. 3. What is rural…expressed in mobile coverage terms? …and why current spectrum policy leads to mobile spectrum waste in rural areas DEFRA Data 56.4m 86% Using the 3.4-3.6 GHz band as an example
  4. 4. Turning “geographic” spectrum waste into a 5G success story:
  5. 5. Which is the best band to begin to win the benefits of dynamic spectrum access for the 9m British people living in rural areas? Non-starters: 3.8-4.2 GHz band : too far away 26 GHz : too poor for coverage 3.4 GHZ 3.6 GHZ 3.8 GHZ Exclusive: But dynamic spectrum access could be via voluntary spectrum pooling Shared: Dynamic spectrum access via over-licensing on non- interference basis 3.4-3.6 GHz: already auctioned 3.6-3.8 GHz : ideal band • Perfect compromise of capacity and coverage • Soonest to arrive in all smartphones and devices • Likely to become the most widely diffused in the installed base • Ultra-low cost Gb/s cells will arrive in the market much faster Combine the best of exclusive and shared access Scope could be: •Rural public cells •Rural self provision •Building owners (if enough screening)
  6. 6. 1. An operator must have “anchor” spectrum in the 3.6-3.8 GHz pioneer band to qualify for dynamic expansion rights (to always ensure a basic service) eg 20 MHz 2. Where operator A is the sole operator at a location, they can expand their radio channel to exploit the full 200 MHz 200 MHz 3. When operator B (owning some of spectrum used by operator A) sets-up a cell at that location, operator A must release the spectrum of operator B THREE SIMPLE RULES – Using current powers for over-licensing non- interfering use Dynamic Spectrum Expansion for the 3.6-3.8 GHz band Source: Prof Temple (How it is to be implemented is a detail for later)
  7. 7. Where the UK is currently trending A view from space of a 5G small cell network* 10 years from now *ASSUMPTION for the illustrations: the same demographics that drive street lighting deployment will drive 5G small cell deployment We have to seize opportunity now to turn a “geographic” waste of spectrum…into a 5G success story National benefits of Dynamic Spectrum Access Where the UK should be trending
  8. 8. Summary:  Only spectrum about to perish is used  Simple, low cost and flexible  Can be implemented quickly  Gets 100% of spectrum into local use in every locality  Unlocks the power of the 5G technology to deliver Gb/s data rates by giving it the bandwidth  Offers a fairer deal to those 9m citizens living and working in rural areas of the UK  MNO winning spectrum in the 3.6-3.8 GHz band enjoy the same practical advantages as for exclusive spectrum in 3.2-3.4 GHz but at a lower price/MHz …and nobody is losing out from it The question is not, why…but why not? And why not now?
