4.7.1 Uniform density mode - simulation radius calculation

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

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

 

The simulation radius is calculated by using the following formula:

In the example of Figure 120, this gives:

Then for a single interefering link transmitter located at the edge of the simulation radius (R = 0.178 km), the iRSSunwanted 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 iRSSunwanted resulting from this terminal may be calculated as:

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

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