This project propose a functional free software option for the implementation and optimization of a Radio Access Network (RAN) focused on a pedagogical purpose to the students can understand the 5G technology. The software called RAN Simulator it is the one selected with this propose due to the capability and option to communicate with ONAP Software which is in the future the software selected to operate Virtual Network Functions (VNF) and Physical Network Functions (PNF). This project has used to optimize a proposal of new carrier add on Long Term Evolution (LTE) which can be described as a new 5G network, this with the tools provided by RAN Simulator which it is capable to analyze and help to avoid and correct issues in a real RAN related to Physical Cell Identification (PCI). The effect of improve a network with this kind of tool can be seeing in the Key Performance Indicators (KPI), where drop calls, errors during hand over, and missing information sent to and from the user equipment can be improved and avoided, this with the immediate effect of offer better service to the users and improve the network. Understand, operate and get conclusions of the RAN Simulator software will be helpful to implement in operating networks and with the option of communication with ONAP, the ONAP software will be a complete option for operators due to the possibility of improvement and implement changes to the network.
