  37. 37. In Summary  London “activities” in 2012 have accelerated the deployment of 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  Next steps • Study further Femto/Wifi and Micro/Wifi integration • Study further the interaction with the Macro layers (EAP-SIM) • Further prove 5GHz/Fibre, 5GHz/28GHz • Investigation of other small cell backhaul technologies › VDSL › 28GHz Mesh, 60GHz P2P Small cells need to also come with a small cost!REC/12/083, Issue 3, 1/10/12 Confidential 37
