Increasing Sensitivity (was Re: [MLB-WIRELESS] <PLUG> Cheap prices for wireless gear)

[John Dalton]

On the subject, it would be an interesting
experiment to strap a Peltier device to a WLAN
card and see if freezing it lowers the
noise floor, increasing its sensitivity.
Might be useful for those who are into distance
records?

Two things to watch out for:

1) Make sure the low temperature doesn't cause
   condensation inside the card, causing it to
   to de-tune.
2) The temperature shift may cause oscillators to drift
   off channel.  Maybe keep both ends of the link
   at the same low temperature to combat this effect?
