Fig. 15.3 Schematic of the multi-level-model
mobile radio network of a city center or a whole country. It will determine the user
density and network utilization intensity. The time reference is also important for
environmental assessments, as the energy demand and material demand accumulate
differently over a certain time duration. It furthermore allows to assess the network’s
energy consumption very detailed using dynamic load profiles on an annual, monthly,
daily or even hourly basis. The definition of the time horizon is important in the
preparation of forecasts, since this also determines technical parameters. The available technology (legacy and new), as well as the available frequency spectrum influences network capacity and defines the network deployment scenario. Based on these
conditions and parameters, it is now possible to select the network architecture and
create the first process flow. The flowing list summarizes the parameters of the first
modelling step:
Area and time scope:
• Total reference area (Germany)
• Model granularity/reference area (km
