[ns] Another CSThresh Question

[Rohan S]

Hi Saikat, 
In your previous post, you have mentioned that you can
use the same program threshold.cc to calculate
RXThresh and CSThresh 
http://mailman.isi.edu/pipermail/ns-users/2003-November/037646.html

and I did just that. However if I calculated the
CSThresh for 40m, that doesn't mean the CS range is
40m right. 

I am using the FreeSpace Prop model, is there a way to
set the carrier sense range to 40m in the TCL code, if
not how do I go about doing so (what paramaeters do I
have to change) ?

Thank You
