Dear All, I want to ask about the receving RxThreshold. I compute it for two distances, one with 300m and the other with 1000m, using TwoRayGround propagation model. I have for 300m , the following output: distance = 300 propagation model: TwoRayGround
Selected parameters: transmit power: 0.281838 frequency: 9.14e+08 transmit antenna gain: 1 receive antenna gain: 1 system loss: 1 transmit antenna height: 1.5 receive antenna height: 1.5 Receiving threshold RXThresh_ is: 1.76149e-10 Then, I applied with the same parameters for distance 1000m, and I have the following output. distance = 1000 propagation model: TwoRayGround Selected parameters: transmit power: 0.281838 frequency: 9.14e+08 transmit antenna gain: 1 receive antenna gain: 1 system loss: 1 transmit antenna height: 1.5 receive antenna height: 1.5 Receiving threshold RXThresh_ is: 1.42681e-12 I used the first receiving threshold 1.76149e-10 with distance of 300m of communication range. And I find that the communication is close to 300m. However, when I increased the distance with 1000m of communication range (RXThresh_ is: 1.42681e-12), then I found that the maximum communication range between nodes is 550m. It seems strange to me, that's why I want to ask, if I had to change the initialization parameters (Frequency, Transmission Power,..), because I didn't change them (I used them as their default parameters in threshold.cc file). Could you please, give me a hand, and if I have to modify some other parameters in WirelessPhy. Thank you, and Best regards.
