Point of fact:

1) unless you have a rather expensive spectrum analyzer, 802.11b
   'packets' will look a whole lot like (low, wide) noise.

2) Most NICs have a 'test' mode that puts the card into a continous
   transmit mode (required to get through FCC testing.)  On a Prism 2
   this is "test mode E".
