The main goal of this Project consists in developing a remote radio head for a LTE system by means of srsLTE software. We used LimeSDRs boards acting as RF front-ends which have been connected to the computers through USB 3.0. The system has been tested first by using two computers to execute the eNodeB and the EPC software. Multiple performance tests have been carried out using a mobile phone first and later a second PC acting as UE. Once each part of the system were already configured and they work independently, the eNodeB can be executed in a cloud by using virtual machines. It required modifying the original srsLTE enodeB code to remove the dependency with RF front-ends. To incorporate the Cloud we considered, Openstack. This is an infrastructure manager dealing with available computing resources and where the instances could be managed. Finally, taking into account the remote radio head outdoor test, we designed and developed a box for protecting the RF board. This Project describes all previous activities that have to be taken into account to follow the complete development of the remote radio head, as also all the explanations of the configurations and possible issues during the system development process. In the annexes, the RRH protection planes designed in Solidworks, the used libraries for srsLTE software, and previous tests of the LimeSDR are included. By last, in conclusions, software defined radio advantages and disadvantages are detailed.
