TUCAN3G is built upon the basic premise that considers information and communications as a key factor of human development. The diffusion of ICT in developing countries has been very asymmetric between densely populated urban areas and isolated rural areas. Geographical conditions have often conditioned solutions for Internet connectivity in rural areas, often based on wireless 2G cellular technologies. From a technological and socio-economical), this project proposes to study the introduction of 3G Femtocells (and its evolution to 4G) in outdoor environments, with backhauling heterogeneous WiLD (WiFi for Long Distances) - WiMAX - VSAT, to provide access to voice and data services to remote rural areas in developing countries. More specifically, the project aims to three specific objectives framed in: (SO1) technology development, (SO2) market research and elaboration of business models, and (SO3) in verification through proofs of concept in platforms installed in basins of the rivers Napo and Putumayo (Peru), which will allow deploying several femtocells in 4 remote rural locations. The technological objective (SO1) aims at optimizing access networks FWI (Femto-WiFi Integration) and heterogeneous transport networks WWVI (WiLD-WiMAX Integration VSAT) to provide 3G service to isolated rural populations in a progressive way . This objective will adopt interference management solutions studied in the ICT project FREEDOM (www.ict-freedom.eu) for the outdoor rural scenario and will introduce LIPA (IP Local Access) and SIPTO (Selected IP Traffic Offload) features to reduce the burden on the transport network. On its turn, optimal solutions for resource allocation and flow control for WiLD transport networks (WiFi parameterization for long distance and quality of service management) and VSAT (hard & soft acceleration) will be derived. In all cases we will consider the critical factors associated to the energy consumption.
