Ok let us supose the Pt_ value is 0.282w . At that transmission power level to have transmission range of 250m RxThreshold 3.65472e-10.If you take carier sense range double the tx range ie 500m the csthresold will be 1.559e-11.
So set it like this Phy/WirelessPhy set CSThresh_ 1.559e-11 Phy/WirelessPhy set RXThresh_ 3.652e-10 Phy/WirelessPhy set Pt_ 0.2818 These are the parameters u have to set at the starting of the tcl script.
