Note: The calculation of the iRSS at each trial will be performed only if the location of the ILT satisfies the following condition .

Figure 133 129 presents how to set-up SEAMCAT (See also A13.2 for further details).

The simulation radius (see Figure 135131) may then be calculated by using the following formula:

If the distance between the VLR and the ILT is equal to the protection distance (0.5 km), then:

...

These results are in line with those depicted on Figure 135131. We can then increase the number of active transmitters to 10 as shown in Figure 136132.
