Santo Tomás University does not currently have the entire telecommunications infrastructure that allows its students to perform laboratory practices in the area of mobile telephony. Therefore, this research work has the purpose of implementing a mobile cellular telephone base (TMC), GSM 2G and the development of a LTE 4G signal reception system, all this through the use of software-defined radio and free software tools. The implementation of the base station generates and manages the wireless resource issued by it, in order to provide short text messaging services and voice call. On the other hand, the LTE 4G signal reception system was developed in the GNURadio software, which allows replicating a didactic and educational form of the whole process of generation and reception of basic mobile telecommunications services.
