Nigel King - UK WISPA - Flexible Spectrum Access

  1. 1. Flexible Spectrum Access Nigel King 21 May 2018
  2. 2. 3.6 to 3.8 GHz Sharing Opportunity • Auction in 2019 • Ofcom still consulting • WISPs need the Spectrum in Rural • 7% of properties do not have access to superfast broadband (Ofcom Number) • ~1% do not have access to any broadband • MNOs need the Spectrum in Urban • 7% of the landmass • 83% of the population • MNOs will not deploy in this frequency band in rural • Surely this can be made to work in a simple manner
  3. 3. Mobile inability to use 3.5GHz Spectrum in Rural • Trees have 3 times the loss at 3.5GHz than at 1.8GHz • Houses have 6dB more loss at 3.5GHz than at 1.8GHz • Power limits close to the maximum already for safe operation • 5GIC have stated in consultation that this band will not be used in rural • Vodafone have stated to me that they will not deploy this frequency in Rural • 93% of the landmass will remain unused without geographic sharing
  4. 4. Advantage to WISPs of using 3.5GHz • Only currently able to use 5.8GHz for mass deployment • Not able to provide Service Level Agreements • Need more than 2x the number of base stations to cover an area to 99% than at 3.5GHz • Nevertheless • Demonstrated 300k properties deployed (Ofcom figure) • 107 WISPs using 5.8GHz spectrum (Ofcom figure) • 3.5 GHz gives • Much longer range at least 2x • Penetration through some trees • Protection from interference
  5. 5. WISP Networks • Much greater capacity than mobile 5G networks (efficient spectrum use) • Many low cost unobtrusive base sites giving high Mbps/sqkm • Directional Subscribers (CPE) giving good frequency • 256QAM capability normal • MUMIMO Normal • Connectivity through • 7m CPE height • 1 point on house required • High gain at (CPE) giving high uplink and downlink gain
  6. 6. Sharing methods (1) • MNOs • Need to decide what areas they want – I suggest a list of OS 1km squares • Need to sign up to deploying in those areas within 5 years – I suggest 90% of purchased areas • Need protection from the WISPs – I suggest a 5km clear zone. • WISPs • Need simplicity • Need low cost licenses • Providing for a public need - sometimes subsidized • Each need to be able to start small and increase area and capacity through time • No need for space between WISPs • Normally arrange frequency reuse plan with neighbouring WISPs • Enough total spectrum for 2 WISPs in an area if 3.4 to 3.8GHz was revisited • Certainty of use for 7 years • Fast reallocation on business failure
  7. 7. Sharing Methods (2) • Equipment specifications • Need to ensure that low cost mobile (LTE/5G) chipsets are useable • May mean that DSA processes are inapplicable or required • Whitespace and CBRS specifications have caused extra equipment cost • Spectrum Trading regulations are not obvious • I have asked Ofcom Trading desk a week ago without response • Regulation looks complex • Looking for comments and plan of action
  8. 8. THANK YOU This cannot be difficult!
