Type of Network Simulation

For radio network planning different types of simulations are available. Static simulations can be done either with homogeneous traffic assumptions for each cell of the networks, for example, using cell loads, or with location dependant traffic definitions. Monte Carlo Simulations use randomly distributed users, which are generated according to location dependant traffic definitions.

Simulation Parameters

Simulate Each Carrier Individually

For network projects with multiple assigned (frequency) carriers the ProMan provides the additional option to simulate each carrier individually. In this case the results are generated for each carrier individually (based on the individual cell assignment, assuming only the investigated carrier is defined) plus the “superposed” results considering all defined carriers (based on the corresponding cell assignment considering all carriers). Accordingly the “superposed” results include the resulting value for the serving cell on each pixel (the throughputs from different carriers are not superposed).

Maximum number of Monte Carlo simulations

Maximum number of snapshots (random samplings) during Monte Carlo simulation.

Note: This option is only available if Monte Carlo Simulation (location dependent traffic) check box is selected.

Draw mobile stations on screen during simulation

Draw mobile stations generated for each snapshot.

Note: This option is only available if Monte Carlo Simulation (location dependent traffic) check box is selected.

Selection of Mobile Stations for Cells

This option allows you to change the algorithm for the selection of mobile stations during cell assignment. Besides a default algorithm which is implemented in WinProp, it is also possible to implement a user-defined algorithm for the assignment of mobile stations to the cells of the network via an open application interface.

Selection of Mobile Stations for Cells

The algorithm for the assignment of mobile stations to the cells of the network can be selected if user-defined algorithms are implemented. Otherwise the default algorithm implemented in WinProp is used.

The algorithm implemented in ProMan sorts the generated mobiles and assigns them to the cells beginning from the first one until the maximum cell load is reached. All further mobiles are blocked.

Optionally the position (the priority) of the defined applications can be used to prioritize mobiles during selection for cells.

The randomly generated mobiles can be sorted either according to their path loss, independent of the actual cell load and interference situation or re-sorted after each modification of the cell load (according to the current interference).

Reports for Traffic Analysis

During simulation with location dependant traffic different reports for additional analysis can be stored in the result directory.

Note: This option is only available if Static Simulation (location dependent traffic) check box or Monte Carlo Simulation (location dependent traffic) check box is selected.

File Formats: The desired file format for the reports can be selected depending on further processing.
Evaluation Options: Evaluation details can be written for each defined application as well as for each clutter class used for the location dependant traffic definition.
Number of Reports: Reports can be written either only after convergence is reached or for each iteration step of the simulation.
Interaction between Cell Planning and Monte Carlo Simulator: Specify how to write the reports.

Cell load and traffic definitions used for interference calculations: These settings are specified on the Traffic Settings tab.
Interference Ratios: [Optional] Consider the influence of the polarization on the transmitted signals.

Figure 3. The Interference ratios dialog.

If transmitting antennas with different polarizations (V/H or +45°/-45°) are used within the radio network the co-channel interference depends on the polarization. Individual interference ratios depending on the LOS/NLOS situation and the polarization relation can be defined. Orthogonal polarization means 90° difference (for example, V and H for the two considered antennas) and different polarization means 45° difference (for example,V and +45° for the two considered antennas).
