The number of active transmitters that will be uniformly located within the simulation radius is given by:

(Eq. 28)

Figure 120 presents the GUI with the input value.

(Note that the results of the simulation radius is displayed only after running simulation)

The simulation radius is calculated by using the following formula:

(Eq. 29)

In the example of Figure 120, this gives:

Figure 121: iRSS using the simulation radius for 1 active transmitter (R=0.178)

Figure 122: Calculated simulation radius with 1 active transmitter

Then for a single interefering link transmitter located at the edge of the simulation radius (R = 0.178 km), the iRSS_unwanted may be calculated:

When increasing the number of active transmitters to 10 (see Figure 123), the simulation radius becomes:

Then, for a single interefering link transmitter located at the edge of that simulation radius (R = 0.564 km), the iRSS_unwanted resulting from this terminal may be calculated as:

If 10 active terminals are located at the edge of the simulation radius, the iRSS_unwanted may be calculated in the following way:

Then the iRSS_unwanted should be above -24.5 dBm as shown on Figure 124.
