9.3.2.4.2 Operational Model
The operational model quantifies the total data rate and bandwidth used by the rail sector in Europe. It
also takes into account the communication tariffs depending on each technology.
9.3.2.4.3 Deployment Model
The deployment model quantifies the km of rail present in Europe, the number of terminals required,
gap fillers, SATCOM hubs and base stations.
9.3.2.4.4 Formulation of the model
As mentioned previously, the model is structured in terms of CAPEX and OPEX cost for each solution
group (terrestrial or SATCOM). In this section, flow diagrams will be used to detail how the cost model
has been built and how the costs have been modelled.
9.3.2.4.4.1 CAPEX
The CAPEX costs for terrestrial and SATCOM exhibit significant similarities regarding terminal costs.
Each technology has its own terminal price and investment requirements. Nevertheless, the same
strategy has been applied for both solution groups. The main difference between terrestrial and
SATCOM regarding CAPEX costs is that the SATCOM solution requires gap fillers while terrestrial
requires base stations.
Figure 72 shows the flow diagrams for computing the CAPEX depending on the solution group.
