  7. 7. 7 09/05/2014 LSA Trial 3 in DySPAN 2014 (McLean, VA)
  8. 8. 8 09/05/2014
  9. 9. 9 09/05/2014
  10. 10. 10 09/05/2014 Regulation, standardization, business Contributions to CEPT on LSA concept (ECC Report 205) and ITU-R on cognitive radio systems in the land mobile service with chairmanship. Business studies on LSA work flow and tasks of key stakeholders, business models for MNOs, scenarios for incumbents and benefits for key stakeholders. Technical research on LTE SON and LSA architecture. Finland (Finnish Trial program) as the single most contributing country at COST Action IC0905 TERRA 2010-2014.
  11. 11. 11 Lessons learnt
  12. 12. 12 09/05/2014 Lesson 1: The Power of Collaboration Trial program introduced a new way of doing research in a collaborative way Required a big change in attitude which was not always easy Project internal between organizations (research, industry, regulation) Between Trial program projects Collaboration turned out to be the key for achieving big results Concrete example: Joint LSA trials Collaboration should continue to share information and avoid overlapping and duplication of work
  13. 13. 13 09/05/2014 Lesson 2: Holistic view covering interrelations of technology, research and regulation Regulation (CEPT, ITU-R) Standardization (ETSI, 3GPP) Business aspects Technical research Trials All interrelated and on the same topic.
  14. 14. 14 09/05/2014 Lesson 3: Agile/Lean/Iterative methods for trial development Consecutive public LSA trial demonstrations with new features (several per year) Force you to work efficiently by selecting and developing the most important features first, integrate and test continuously with others Opportunity to collect feedback from stakeholders Essential in the development of new concepts whose features are unknown in the beginning of the project Opportunity to take into account technical/business/regulation developments in the trials
  15. 15. 15 09/05/2014 Lesson 4: Publicity LSA concept brought to the attention of the whole world Public trials in Europe, US and Asia (?) to promote the LSA concept and Finland’s cutting edge position in spectrum sharing Presentations to all involved stakeholders in different forums with clear and simple messages to collect feedback Regulation (regulatory forum workshops), research (academic conferences), and industry Active publication work coupled with trials to get publicity Trials and papers in same events
  16. 16. Trial environment future plans
  17. 17. 17 09/05/2014 Other related activities – European LSA development LSA concept development in Europe continues in ETSI and CEPT Only 2.3-2.4 GHz band considered so far European Commission Current mandate on geolocation database Upcoming mandate on the 2.3-2.4 GHz band for wireless broadband with LSA (if needed) in 2015 On-going work on RSPG report “Efficient awards and use of spectrum bands harmonised for Electronic Communications Services” (best practices on spectrum award approaches and related conditions, including spectrum sharing and/or pooling with a view to achieve higher transmission speeds and capacity in 2015) Identification of beneficial sharing opportunities (BSOs)
  18. 18. 18 09/05/2014 ETSI timeline for LSA TS 103 235: System architecture for LSA, target Nov 2014 TS 103 154: System requirements for LSA in 2300- 2400 MHz, target Aug 2014 Interface definitions expected to start in 2015 2013 2014 2015 TR 103 113: SRdoc Mobile broadband services in the 2300 – 2400 MHz band under LSA
  19. 19. 19 09/05/2014 Other related activities US spectrum sharing developments Three-tier hierarchy model under study in 3.55-3.65 GHz band ITU-R work on spectrum sharing ITU-R WP5A will finalize its work on CRS in 2014 giving the general guidelines for spectrum sharing ITU-R WP1B work on “dynamic access” is on-going and could expand in the future Current sharing models (LSA and US model) are only for the first band – and not yet implemented even there There is a need to continue the spectrum sharing studies and trials
  20. 20. 20 09/05/2014 Future trial topics New interfaces in LSA Larger LSA LTE network Different types of incumbents Visualisation Small cells and clusters of small cells LSA with Active Antenna Systems (AAS) Load balancing and traffic steering Interference studies
  21. 21. 21 09/05/2014 Conclusions Power of collaboration Trial program introduced a new way of doing research in a collaborative way => This has led to results with big impact. Holistic view covering interrelations of technology, research and regulation Looking at the concept from different angles improves the quality. Agile/Lean/Iterative methods for trial development Consecutive public trials increase the quality by getting feedback. Publicity Spectrum sharing still requires further research and trials Current models (LSA and (US model) are being studied for single band and not yet implemented even there.
