Small cells and C-RAN: can they work together- Mobile World Congress 2014

  1. 1. Small cells and C-RAN: can they work together? Caroline Gabriel Research Director Maravedis-Rethink Mobile Operator Strategy Analysis CLIENT CONFIDENTIAL 1 Copyright © Maravedis Inc 2014.
  2. 2. Agenda • • • • • • February 2014 The operators’ 4G challenge Small cells – part of a wider network Evolution of C-RAN Early adopters How the two architectures support each other Next steps to HetNet www.maravedis-bwa.com CLIENT CONFIDENTIAL 2 Copyright © Maravedis Inc 2013.
  3. 3. February The 4G Challenge New topologies needed200 profitable 4G for 180 160 140 120 $bn • Operators must invest to handle 13fold rise in mobile data • With conventional technology, 4G capex will outrun revenue at least until 2017 • Solution: new infrastructure topologies and intelligence • LTE not enough on its own – a new way to build networks is needed for 4G to deliver full benefits 2014 100 80 60 40 20 0 2013 2014 2015 Capacity investments 2016 2017 2018 Data revenues Operator predicted capacity capex vs revenue Source: MOSA, MaRe survey 65 carriers www.maravedis-bwa.com CLIENT CONFIDENTIAL 3 Copyright © Maravedis Inc 2013.
  4. 4. February Two architectures 2014 Macro and small cell layers – new economics 350 • • • • • Compact small cells overtake macrocells in numbers 2014, by capex 2016 Small cell sales reach 15.2m in 2017, CAGR of 240% But this could be chaotic capacity Move towards two architectures – distributed and metrocell Macro base stations increasingly deconstructed leading to Cloud-RAN Intelligence focused in core or at the edge? Key to have intelligence end-toend 300 3,500 3,000 250 2,500 ,000 units • 4,000 200 2,000 150 1,500 100 1,000 50 500 0 0 2013 2014 Macrocell 2015 2016 C-RAN 2017 2018 Small cells Small cell and C-RAN macrocell growth Source: Maravedis Rethink RAN Services www.maravedis-bwa.com Source: MOSA Source: MOSA, MaRe survey 65 carriers CLIENT CONFIDENTIAL 4 Copyright © Maravedis Inc 2013.
  5. 5. February Many tools needed • • • Operators will use many tools Rising value of access to LTE spectrum and fiber But many other tools in play to achieve capacity New technology LTE upgrade Wi-Fi offload Public access small cells Deconstructed RAN (RRH and distributed antennas) New or refarmed spectrum and carrier aggregation LTE-A key features CoMP, eICIC Adaptive networking/SON 2014 % of required capacity increase 17% 16% 14% % of required TCO decrease 14% 20% 18% 11% 17% 17% 9% 14% 10% 11% 12% Capex spend on 4G RAN by base station type www.maravedis-bwa.com Source: MOSA Source: MOSA, MaRe survey 65 carriers CLIENT CONFIDENTIAL 5 Copyright © Maravedis Inc 2013.
  6. 6. February Technology milestones C-RAN part of a broader trend • Build on existing trend to separate radio head from baseband, RRH, base station hotel • RRH becomes intelligent antenna array • Enablers - antenna/radio integration; Active Antenna System • 2014 Elements of C-RAN • Baseband processing virtualized for >50 BTS per central server blade • Each BTS can be further extended with low cost antennas • Source: VPISystems Target $50 cell site at low power www.maravedis-bwa.com CLIENT CONFIDENTIAL 6 Copyright © Maravedis Inc 2013.
  7. 7. February Early deployers The first trials • • • • • • China Mobile driving ecosystem • Intel, ALU etc KT Cloud Communication Center • ‘Connect and Development’ to address intercell interference NTT Docomo Advanced C-RAN • AAS trials, driving Supercell and Phantom Cell SK Telecom SCAN • Seoul 1722 RUs, 609 DUs, 200K repeaters European interest eg DT All major small cell deployers also www.maravedis-bwa.com 2014 C-RAN at China Mobile.

  8. 8. February What’s needed to reach reality? 2014 Key steps still required to hit new economics • A C-RAN which integrates fully with small cells and Wi-Fi – Key enablers – CoMP, SuperCell • A C-RAN architecture which does not require fiber at every cell site – Key enablers – CPRI over microwave, CPRI/DAS integration, wireless fronthaul • Commoditized software and chip platforms – Key enablers – off-the-shelf Intel or ARM processors, common programming languages, ultra-low cost modem www.maravedis-bwa.com CLIENT CONFIDENTIAL 8 Copyright © Maravedis Inc 2013.
  9. 9. February C-RAN challenges and solutions Integration with small cells 2014 • Advanced C-RAN – master BTS • Small cells and distributed antenna extend BTS • Shifts economics again www.maravedis-bwa.com CLIENT CONFIDENTIAL 9 Copyright © Maravedis Inc 2013.
  10. 10. February C-RAN challenges and solutions SDN and elastic networking • Software driven capacity • Dynamic switching of capacity in urban areas • Move to SDN – C-RAN one app in NFV • But specialized processing and local presence also needed www.maravedis-bwa.com 2014 C-RAN in the NFV, Intel Source: MOSA Source: MOSA, MaRe survey 65 carriers CLIENT CONFIDENTIAL 10 Copyright © Maravedis Inc 2013.
  11. 11. February Developments 2014 • More processing power at the edge • Distributed core • Virtualized core and RAN functions • Backhaul • Advanced SON, location and presence • Changes to OSS/BSS approaches • Operator confidence Source: Intel www.maravedis-bwa.com CLIENT CONFIDENTIAL 11 Copyright © Maravedis Inc 2012.
  12. 12. February Macro interworking Small cells achieve full potential • Hybrid architectures 10,000 800 9,000 700 8,000 7,000 600 ,000 sites • Key trends • Cloud-RAN • Super Macro 900 6,000 500 5,000 400 4,000 300 3,000 200 • Integration of these technologies • Offload • Super sites • CoMP ,000 sites • Macro layer continues to evolve too 2014 2,000 100 1,000 0 0 2013 2014 C-RAN primary sites 2015 2016 C-RAN sub-sites 2017 2018 Small cells inc WiFi Cloud-RAN deployments Source: Tearing the Network Apart; The economics of the new RAN, Maravedis-Rethink October 2013 www.maravedis-bwa.com Copyright © Maravedis Inc 2013.
  13. 13. February Evolution of HetNet The two layers converge in Elastic network • • • • 2014 Carriers’ ultimate goal is heterogeneous network Full interworking and hand-off between macro layer and metro layer Different technologies (3G, 4G, WiFi) in different spectrum bands behave as single pool of capacity Common core, management and policy tools allocate resources where most needed The HetNet evolves.
