Implementación de una herramienta de radio definido por software que emule una red de telefonía celular móvil para ser usada en la enseñanza dentro del programa de ingeniería electrónica

Cellular telephony is one of the most basic forms of communication today, which requires an understanding by professionals trained in this field. In order to expand the access to this technology, a software defined radio tool was developed to analyze the operation of a GSM cellular telephony system; for this purpose, a review of the current state of the literature was carried out under 3 thematic axes, Trends in Software Defined Radio, Trends in Systems based on OpenBTS and Trends in tools for the modeling and implementation of a mobile cellular telephony system. To carry out this work we used the USRP N210 device, the free software OpenBTS and Asterisk in the operating system Ubuntu version 12.04, the communication standard used by the GSM, in order to implement a software defined radio system. The development of the work was divided in 4 phases; the first one identified the characteristics of the OpenBTS prototype to be developed, in which the necessary components to implement the system were determined and precedents were looked for; the second one allowed the characterization of the system to be developed, defining the software and hardware tools; in the third one the implementation and configuration of the proposed system was developed; finally in the last phase tests were made in the system. Based on the above, different tests were carried out in order to determine the maximum range of the signal in free and urban space; level of loss in the calls; connection of multiple mobile phones; call quality; sending of text messages. The result of the tests established that the device has a range of 120 m, its call quality and sending of messages are good.
