Education and e-health for developing countries using NVIS communications

In this paper we present a new communications solution for remote villages in developing countries. The system is based in the Near Vertical Ionospheric Skywave (NVIS) technique, able to achieve coverage areas up to 250 Km without line of sight. It is a low-cost, low-power system that can be easily installed and put into operation. The radio system communicates with a smartphone, where a messaging app is running, so text and low resolution images can be sent without the need of any mobile operator. The system has been tested between one of the Andean communities of the Sacred Valley of Incas in Peru and Urubamba, the nearest city.
