Transcript

  • 1. LTE Metrocells Telco Evangelist 23 January 2013 London
  • 2. About ThinkSmallCell• David Chambers, B.Sc. • Metrocell MasterClass (Hons), MIET, C.Eng, “Become a Metrocell Expert Dip. M., MCIM, in one day” • 3 independent industry Chartered Marketer experts• Founded Sept 2007 as • Choice of 2 locations ThinkFemtocell – 21 Feb: IET, Savoy Place, London• Independent news, – 21 March: Homerton analysis, insight into Conference Centre, Cambridge Small Cells • bit.ly/Metrocell Sign up for our free monthly newsletter on all aspects of Small Cells at ThinkSmallCell.com
  • 3. Agenda• Why small cells?• What are LTE Small Cells?• Where and when LTE metrocells will be introduced• Metrocell Backhaul• Technical and practical constraints• Potential market size
  • 4. Coopers Law – Looking back• The number of voice or data conversations which can be conducted by all useful radio spectrum within the same area.• Doubled every 2.5 years for 100 years Of 1 million times improvement in last 45 years • 25x additional spectrum • 25x spectral efficiency • 1600x spatial efficiency (i.e. smaller cell sizes)
  • 5. Cooper’s Law – Looking ahead • 3GPP workshop[1] on how best to grow capacity 1000x capacity increase can be achieved by: – 3x additional spectrum – 6x spectral efficiency – 56x spatial efficiency (i.e. small cells)[1] June 2012: http://www.3gpp.org/Future-Radio-in-3GPP-300-attend
  • 6. Differing scope of small cells terms Small Cells ORFemtocells Small CellsResidential Enterprise Metrocell Rural
  • 7. Different scope of small cells 3G 4G/LTE Unlicensed Licensed Licensed Spectrum Spectrum SpectrumPlanned 3G LTE Carrier(location pre- Metrocells Metrocells Wi-Fidetermined prior to 3G Rural LTE Ruralsite build) Small cells Small cells Enterprise EnterpriseUnplanned Wi-Fi Femtocells(location unknownuntil operational) Residential Residential Femtocells Wi-Fi

  • 9. Modular Design Height: 296 mm (11.6 in.) Width: 124 mm (4.9 in.) Depth: 118 mm (4.6 in.) Volume: 4.3 l (1.1 gal) ~3.5 kg (7.7 lb) Power: 40W Capacity: 32 concurrent voice/data sessions*Alcatel-Lucent 9764 3G Metro Cell Outdoor
  • 10. Coloured to match: Cameleon AtomCell Invisible Design :*Huawei Atomcell
  • 11. Street Layout
  • 12. The Mobile Network Architecture including LTE Interfaces 2G 3G Data (IP) Voice (PSTN) Network Network 2.5G 4G GGSN PDN-GW S5 Gn S11 Gs Core S4Network MME S-GW SGSN MSC S3 Iu-ps Iu-cs S1-MME S1-U Iur RNC RNC Access X2Network Iub eNodeB’s Node B’s Air LTE-UuInterface Uu UE UE
  • 13. SKT LTE Small Cell Architecture Typical Femtocell Gateway specifications: • Up to 100K LTE small cells per gateway • Up to 3.8Gbit/s total traffic capacitySource: SK Telecom June 2012
  • 14. System Engineering Issues• Timing/Sync – LTE Advanced requires Phase & Frequency sync• Self-Organising – Self-Configuration – Self-Optimisation – Self-Healing• Beam forming – Tailored radiation footprint to reduce macrocell interference
  • 15. Choice of Spectrum• Higher frequencies • Shared vs – Shorter range Dedicated – Lower in-building penetration Spectrum – Less interference Macrocell Metrocell700 800 900 1800 1900 2100 2300 2600 3500MHz MHz MHz MHz MHz MHz MHz MHz MHz 10x Spectrum Pricing Differential 1x
  • 16. Backhaul Capacity It’s debatable how much required - Typical might be: 30-60Mbps per small cell 1Gbps per cluster including macrocell 10Gbps major concentration points*Source: NGMN BackhaulRequirements 2012
  • 17. Backhaul Considerations• Hot-Spot or Not-Spot• Point-to-Point vs Point-to-Multipoint• Reliability vs Availability• Line-of-Sight or NLoS• Capex vs Opex• Installer Skillset
  • 18. Backhaul Wireless Spectrum 800MHz 6GHz 57GHz 64GHz 85GHz Optical 600THz TV White Microwave 60GHz Space Non Line-of-Sight E-BandDynamic & Unlicenced or Licenced Lightly Lightly Licenced Licenced Unlicenced
  • 19. SK Telecom LTE small cell roadmap
  • 20. Deployment Issues• Three main concerns – Site acquisition – Power – Backhaul• But also – Planning tools to identify ideal site locations – Skill set for technicians to install equipment – Scalability of planning, deployment processes – Reducing future site visits
  • 21. New commercial models• Metrocell Hosting – Virgin UK – COLT – BT• Benefits – Councils/landlords deal with few suppliers – Operators outsource to companies with matching skillsets and fieldforce
  • 22. Forecast Growth*Source: Rethink Research
  • 23. Metrocell Masterclass• Become a Metrocell Expert in one day – 21 Feb 2013: The IET, Savoy Place, The Strand, LONDON – 21 Mar 2013: Homerton Conference Centre, CAMBRIDGE• Learn from three small cell experts – David Chambers/Zahid Ghadialy/Justin Paul• Full details and online store – bit.ly/Metrocell – ThinkSmallCell.com• Discounts for early booking & 3 for 2 offer
