There's also the fact that bodies (full of water) are rather absorbant in the 
2.4GHz band, so when there are a lot of people in the room the signal doesn't go 
as far.

When I'm setting up wifi for a conference, I take advantage of that to let me 
deploy more APs (re-using the channels at closer distances than I could normally 
get away with)
