Introduction Broadband access for rural communities is one of the objectives of the European Commission. The EC FP7 project ICT-601102 STP TUCA
26、N3G, “Wireless technologies for isolated rural communities in developing countries based on cellular 3G femtocell deployments“ has addressed this problem and has provided a system design for deployments of Telefonica in Peru. The present document includes the main outcome of the project. ETSI ETSI T
27、R 103 293 V1.1.1 (2015-07) 61 Scope The present document describes the architecture and implementation guidance for rural BWA based on 3G femto base stations, and a variety of terrestrial and satellite backhaul solutions. The implementation guidance includes self-optimization of physical layer param
28、eters and recommendations for femto-to-femto and femto-to-backhaul interaction. Additionally, deployment examples, at least for Peru, are included. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-
