The Software Defined Radio (SDR), unlike conventional radio systems implemented only by hardware, has had a great impact thanks to the great flexibility offered by the software. The objective of this work has been to develop a remote radio header using the LimeSDR, an SDR board, connected to an ODROID XU-4. The connection will be made through the USB 3.0 port since it allows a high transmission speed. This remote radio header will be incorporated into a Cloud-RAN to facilitate the virtualization of radio resources. As the LimeSDR transmits and receives, the communication between ODROID XU-4 and server is full duplex. Looking for a high transmission speed, the connection between the ODROID XU-4 and the server in the Cloud-RAN will be made using Gigabit Ethernet cable. This communication between ODROID XU-4 and server will be carried out through sockets. To do this, two Virtual Network Functions (VNF) have been developed in such a way that one will be placed on the cloud server and the other on the ODROID-XU4. As the development of the remote radio header progresses, tests have been carried out. These verify the proper functioning of the SDR board, the correct operation of the VNFs, that the remote configuration of the most relevant parameters for transmission and reception of LimeSDR is carried out correctly and that the entire system works correctly. The present work, apart from the development and verification, also has documented an introduction to the software-defined radio, another for the remote radio headend, the design approach, the total number of hours that I have devoted to this work at the end of degree and the technology on which this remote radio headend is based, both its hardware and its software, in order to better understand both the opportunities it can offer and the limitations.
