In such a scenario, the detection threshold is taken to a value of 0 dB (Figure 164) much higher than the sRSS level (average = -82.09 dBm) (Figure 165). Therefore, no victim system has been detected and the WSDs are allowed to transmit in any of the specified channels (Figure 166) per event.

In such a case the e.i.r.p.used in the simulation is the Txpower (=-33 dBm) + Gmax (=0 dBi), meaning that the in-block e.i.r.p. limit does not apply. This means that whatever the frequency selected by the WSD its e.i.r.p.. is the same (Figure 168) (here assuming that the Power Control at the It is OFF).

Figure 169 illustrates that on average there are 1.17 WSDs active at 1000.5 MHz per event, 1.23 WSDs in 1001.5 MHz, 1.34 WSDs in 1002.5 MHz and 1.26 WSDs in 1003.5 MHz for the same out of 5 which were input to the simulation. In this case all the WSDs were active (but in different frequencies) since the sum equal to 5 (i.e. none of the WSDs have been turned off).
