5G is considered the next revolution in communication. Several researches focus efforts in tackling challenges for enhancing data rate, reducing latency, improving connectivity and reducing consumption. However there is one relevant mode that has not been strongly supported by the research efforts, which is Internet access for remote areas. As of today, we estimate 1.4 billion of unconnected people live in areas where mobile broadband coverage is not available, showing the immense impact of a network that can deliver high quality Internet access in remote areas. It is clear that a sustainable rural service will not be available unless network deployments and business strategies are specifically tailored to this scenario. The goal of 5G-RANGE is surpass the limitations of current technologies, making the coverage of low populate areas a feasible business. Clearly, this new 5G mode needs to be flexible to comply with different applications and services.
