That's correct. A student here (HyungJune Lee) has used this
functionality to generate high-frequency (1kHz) traces of
environmental noise. One thing you can do with the noise is then
recreate it in simulation, which can let you create effects that few
wireless simulators support, such as bursty losses. He has a paper on
the technique which will be appearing in IPSN in April; you can find
the submission version of the paper on our website as a technical
report.
Once we've finished with the camera ready, we're going to incorporate
the approach as a TOSSIM 2 module. What's especially nice about the
technique is you can take a noise trace from anywhere and then use it
to generate a simulation model. So you can, for example, simulate the
RF in the location you're planning on deploying a network...
