Estudio y diseño de un prototipo de bajo costo para emergencias utilizando software defined radio sdr y servidor asterisk para aplicaciones en sitios de bajo cobertura.

Abstract

In this project the design, development and implementation of a low-cost telecommunications system through software defined radio is detailed, which provides advanced mobile service access and simulates a communication channel with an emergency entity. the designed system is composed of two interconnected servers through a private local area network which is established using an access point. at the first server, an universal software radio peripheral u2920 from national instruments as hardware and openbts project as software for a base transceiver station implementation are used. although, in the second server, asterisk project to establishment a telephone exchange with call center and interactive voice response is used.
