The proposed project consists of creating a complete LTE infrastructure based on the use of existing LTE libraries and supported by cloud technology. Last years, wireless technology is moving to incorporate cloud computing concepts into the wireless environment. Therefore, eNodeB must be properly virtualized and executed inside the cloud, connecting with the remote radio head, RRH, through high-speed networks. In that project, we propose to set up a complete eNodeB, the Core Network, CN, and the User Terminal, UE, implemented by software and move eNodeB and CN, by means of creation of Virtual Machines, VMs, to the cloud. We envisage several phases in the project development: 1) We need to develop a complete solution, eNodeB, CN, and UE using independent PCs properly connected among them and to the RRHs. RRHs will use USRPs or LimeSDR boards. 2) Full test of the developed system based on independent PCs. 3) In a second phase, we need to address the cloud computing technology, using proper virtualization tools to create the VMs to be deployed into the cloud. We will use a cloud developed using OpenStack. 4) Full test of the developed system based on cloud technology. The complexity of the full system where clearly differentiated component needs to work in cooperation and coordination claims for a wide set of people to work in. Is because of that that we propose a group of three students. Although they must work in close coordination each one of them can address different parts of the work. As the first division of activities, we can think of: eNodeB+CN, UE, OpenStack framework. In that way, students will get a better understanding of the complete system behavior and issues. |

| Overview (resum en anglès): | |
|
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. |
