A simulation scenario is a part of a scenario workspace, which defines all technical parameters of modeled links as well as some related modelling assumptions, such as physical (mutual) placement of transceivers, propagation modelling settings and so on. Within SEAMCAT a simulation scenario is based upon the concept of links. A link stands for a pairing of one transmitter with one receiver[1] operating together in a given radiocommunication systemwireless system. Such a link is also called a “system link”.

When a new workspace is created, all of its scenario elements are populated with default values (representing a hypothetical interference case between two systems at 900 MHz, as shown in Figure 27). Therefore  Therefore after creating a new workspace yourfirst the first step should be to review and modify the scenario parameters so that the resulting simulation scenario reflects the configuration of the radiocommunications wireless systems to be simulated. 

To create or update a simulation workspace, you need to follow the following steps need to be followed: 

1. Set the technical characterisitic of the various systems that you want to investigate. In the example of Figure 26 the first system is Generic and the second one is an OFDMA UL system. Do  Do not forget to export your system the systems used to the library environment so that you can reuse your work next they can be reused  at a latter point of time.

2. Set the scenario (see section ‎10);
3. Set the path characteristics between the victim and the interferer (relative position, interferer’s density, path loss correlation and propagation model). You  Links can also addbe added, duplicateduplicated, etc... links;
4. In The number of events to simulate can be set in the simulation control panel you can both set the number of events to simulate and decide whether you want to run the . It is also possible to choose  whether to run a simulation in the debug mode or not;
5. Having reviewed the scenario, you the simulation can be run your simulation.
