Probably the biggest flaw in the current TOSSIM radio model is that the RSSI is completely constant. The RF community has a bunch of terms they use to describe RF behavior which sound mostly incomprehensible to someone who doesn't know them (fast fading, slow fading, shadowing, etc.). In this case, I think he's talking about the fact that signal strength varies over time in slow fading models.
