DESCRIPTION
The OnCAT Project’s main objective is to provide connectivity to the entire territoryof Catalonia. Previously, is necessary to analyse the viability of the implementation andmake an action plan composed of the different stages of the projectThe first stage is focused on the core and aggregation networks’ design. This isthe stage we studied in this first delivery, which aims to define specifications anddetails of it. The second stage, which defines the access network, will be studied on thefinal delivery of the project. The available budget for the project’s design,implementation and operation starting is about 250M €.This document is structured in some sections that define the different designingparts that we have to take in account. Starting with the calculations requireddetermining the traffic in the regions of the territory and the technological solutionschosen, following the definition of topologies and equipment used, and ending with thebudgeting of the project.
