body	${{R}_{simu}}=\sqrt{\frac{{{n}^{active}}}{\pi \ \times \ dens_{ILT}^{active}}}$

(Eq. 178)

dens_it^active isthe density of active transmitters and is defined as follows:

Mathinline

body	$den{{s}_{ILT}}^{active}=den{{s}_{ILT}}.{{p}_{ILT}}.activit{{y}_{ILT}}(time)$

(Eq. 179)
where:
n^active - number of active transmitters set in the scenario for IT-VR path (note htat that n^active should be sufficiently large so that the (n+1)^th interferer would contribute with a negligible additional interfering power);
dens_it - density of transmitters, 1/km2, user-defined parameter in the table Interferers density of ILT-VLR path;
P_it - probability of transmission, user-defined parameter;
activity_it(time) - user-defined temporal activity function (i.e. look-up table). The time value used for calculation is specified in the parameter time (see below).
time - parameter defining which of the values in the above activity function should be used in calculations (e.g. if the activity(time) function contains three pairs: (1;0.5), (2;0.7), (3; 0.9) and the time parameter is set to 2, then the activity(time) function will return a value 0.7).

body ${{n}_{active}}=den{{s}_{transmitter}}.pro{{b}_{transmission}}.\pi \ {{\left( R_{simulation}^{{}} \right)}^{2}}$
(Eq. 180)

When setting up your simulation, if the relevant input parameter is the simulation radius, it is recommended to use the mode “None” instead of the “Uniform density” mode. In that case, the activity of the transmitter may be simulated using e.g. the parameter duty cycle, which defines a distribution of the transmit power.
