  • Why LTE? • LTE = “Long Term Evolution” commonly referred to as 4G (e.g. 4G iPad) • O2’s trial is achieving peak downlink 100Mbit/s, with 30-50 Mbit/s typical • Compared to 3G, offers: x5Technology x10 x4 Higher peak user Higher spectral Decreased latency throughput efficiency Lower transmission Customer Faster data Shorter waiting costs per Mbit, so experience delivery for users times before data users can have more starts flowing data for their money
  • Telefonica Global LTE FDD Trials

  • London Small Cells – High Density (HD) Femto Deployment
  • London Small Cells – High Density (HD) Femto Deployment Telefonica UK has only 10MHz of U2100 spectrum and therefore has to share a Plot of Best Server HS-DSCH Throughput (Mbps) carrier between Macro and Femto layers For some time now we have been studying 21 22 23 24 25 the feasibility of deploying a dense Femto Distance in bins 16 17 18 19 20 layer under a macrocell 11 12 13 14 15 And more recently we have deployed what 6 7 8 9 10 we believe to be the world’s densest Femto cell deployment 1 2 3 4 5
  • London Small Cells – High Density (HD) Femto Deployment
  • London Small Cells – High Density (HD) Femto Deployment 11 Plots 65 Blocks (1 – 8 blocks per plot) 564 Floors (7 – 11 floors per block) 2818 apartments (typically 6 per floor) Up to 16,962 beds
  • London Small Cells – High Density (HD) Femto Deployment1. External CW TestingThis identified that the building penetration loss was in the order of 20dB for 900MHz and 30dB for 2100MHz.Therefore an in-building solution would be required to provide assured service to users.Subsequent O2 propagation modelling indicated that approx 20% of accommodation was likely to experienceacceptable 3G (2100MHz) service if the two proposed external macrocells are built. This reduces to 11% if theyare not built. For GSM900 the predicted coverage is approximately 40% with and 20% without macrocells.2. Internal CW testingThis confirmed that two antennas (DAS or Femto) radiating +10dBm at 2100MHz could cover all rooms on atypical floor to RSCP -85dBm or better. One antenna would cover to -105dBm or better. Central riser andapartment service cupboard locations were equally effective. Penetration loss between floors wasapproximately 20dB meaning that floors could be covered in relative isolation from each other.3. Femto-cell trialConfirmed that two ALU Enterprise Femto-cells, each located in a selected apartment service cupboardprovides satisfactory 3G voice and data performance in all rooms on a single typical floor. Further testingidentified no issues with femtos interfering between floors.
  • London Small Cells – High Density (HD) Femto Deployment Femto Home Hub Femto cell located within cupboard adjacent to BT Infinity Home Hub. Probably secured with cable ties to rear mesh (as shown by blue square) to minimise potential tampering and theft.
  • London Small Cells – High Density (HD) Femto Deployment
  • London Small Cells – High Density (HD) Femto Deployment
  • London Small Cells – High Density (HD) Femto Deployment Coverage provided via 1200 x ALU Enterprise V1.5 (100mW – 8 user) indoor femtocells with backhaul via BT Infinity FTTx. Deployment, testing and validation concluded. Alcatel-Lucent will provide a Managed Service to monitor and support the Femto Gateway and CPE 24/7. High Density “Open” group deployment proven Densest Femtocell deployment in the world!
  • And Finally: Small Cells - Solar Pole Concept
  • Small Cells: Solar Pole Test & Build Telefonica UK’s first Solar Powered 3G/4G/Wi-Fi Access Point
  • In Summary London “activities” in 2012 have accelerated the deployment of LTE & small cells for Telefonica UK • 3rd Party Poles, Indoor open Femto and Wifi are the way forward • Proven that lamppost mounted small cells are feasible – London Lampposts • Both fibre and Microwave is suitable for backhaul • High Density Open Femto deployments are possible – London Femtos Next steps • Study further Femto/Wifi and Micro/Wifi integration • Study further the interaction with the Macro layers • Further prove 5GHz/Fibre, 5GHz/28GHz • Investigation of other small cell backhaul technologies › VDSL › 28GHz Mesh, 60GHz P2P 2012 was the year of trialling and 2013 will the year of deployment!
