Despliegue de una red 5G NSA implementada en software de código abierto OAI con USRPS ETTUS B210 para el laboratorio de comunicaciones de la FIE.

Abstract

In the present work, a 5G NSA network implemented in Open Air Interface open-source software with USRP's Ettus B210 was deployed for the communications laboratory of the Faculty of Informatics and Electronics (FIE). For the development of this work a descriptive investigation was used, in addition the iterative methodology called Rational Unified Process (RUP) was used, which consists of four phases: in the requirements phase, the requirements that the system must meet, both hardware and software, were defined; In the design and analysis phase, the design that the 5G NSA network must comply with for proper communication between each of its components was established; in the implementation phase, the installation of the evolved packet core (EPC) and radio access network (RAN) components was carried out, using the official repositories of the OAI platform to subsequently launch the network; and finally, in the testing phase, the correct operation was verified. In addition, network measurements were carried out through an Indoor test to determine the coverage within the FIE communications laboratory; The successful connection of a UE to the 5G NSA network was obtained as a result, with response delays of 12 milliseconds and providing the user with access to the Internet. Likewise, tools such as T Tracer and SoftScope were used, which allow the analysis and monitoring of the radio interface of the network. Concluding that, it was possible to implement a 5G NSA network, providing a didactic environment for the study of these technologies. However, it was found that the USRP B210 model has limitations in terms of its bandwidth and sampling rate, which did not allow exploiting the characteristics of 5G obtaining low transmission speeds, therefore, for future work it is recommended use current models and with better bandwidth capabilities.
