| Summary: | The Global System for Mobile Communications (GSM) has been widely accepted around the world. The implementation of this system for a comunity are expensive because to use high-cost equipment, but thanks to the development of software-defined radio systems, it is possible to develop this type of network at a reduced cost. Access to telecommunications services in rural communities in Cuba is today a great challenge, mainly caused by the geographical location and the small number of habitants that make the deployment of infrastructure not economically feasible. The main contributions of the present work focus in an alternative cellular system and GSM network management software. It was shown that it is possible to build a mobile telephone network using free software components and low-cost hardware, which can be used in sparsely populated rural communities, as well as in emergency situations.
