Re: [ns] wireless interference studies



satish,
  i mean two different modulation schemes or two different protocols
operating in the same spectrum (e.g. 2.4 GHz ISM). are there any simulators 
available that would allow you to do that?
  also, regarding your description of the current implementation of 
interference, wouldn't it be more accurate to probabilistically drop the two 
packets to simulate spread spectrum?

thanks,
neeraj
