Hi, I was getting problems with the following 2 simulations: Phy/WirelessPhy set RXThresh_ 630e-15 Phy/WirelessPhy set CSThresh_ 630e-15
and i also added the following lines: Antenna/OmniAntenna set Gt_ 25.0 Antenna/OmniAntenna set Gr_ 50.0 I was using the FreeSpace model, and a distance of 880 m with Gr=50 and Gt=25. After runninn the script for a Pt_ = 0.0158 W (12 dBm), the power received using the Friis formula or the result printed by the function gives: OFDM phy receiving packet with mod=0 and cp=0.250000 0.031842: d: 880.000000, Pr: 1.199811e-09 But if I run the script for Pt= 0.01 W (10 dBm), there is no packet received, and Pr is not printed, but it should be more or less 7.2e-10. My question is, there must be another variable that i'm forgetting, because for 0.01 W, the received power should be 7.2e-10 >> 6.30e-13, I mean 7.2e-10/6.30e-13=1142 W/W, or 30.6 dB. I would like to know where is that 30.6 dB implemented? And then i checked the variable distCST_: for the first case: channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 1086.2 for the second case, Pt_=0.01 W: channel.cc:sendUp - Calc highestAntennaZ_ and distCST_ highestAntennaZ_ = 1.5, distCST_ = 862.8 ->In this case is less than the 880 m. So maybe the missing 30.6 dBm are calculated in the variable distCST_, do you have any ideias? Thanks in advance, Tiago Junqueira
