<br>
When I setup conference wifi, I take advantage of the fact that some walls block <br>
the wifi signals, so I can put the APs closer to the walls that block them <br>
without worrying about what's on the other side. I also place them on the ground <br>
(under the chairs) as the bodies of the attendees absorb the signal and let me <br>
use more APs in a room than I could get away with otherwise. I also stick to the <br>
standard 10MHz channels, as that lets me re-use a channel with more separation <br>
between APs using the same channel<br>
<br>
And yes, I agree that it makes no sense to run an AP at a higher power level <br>
than the stations talking to it, so I turn the power way down.<br>
<br>
I haven't knowingly run into the problem you describe of clients enumerating all <br>
available APs, but I may not have setup a high enough density of APs to run into <br>
the problem, can you give more info on that?<br>

As someone who has been looking at building a house, it's not that simple. Hard <br>
wired smoke detectors are only needed in some rooms, not in all, and only if the <br>
house is above a minimum size. Then you need different amounts of power to get <br>
through walls depending on how they are built.<br>
<br>
When I setup wifi in a conference center exibit hall that's 25,000 sq ft, I <br>
don't believe that there are 80 smoke detectors in that one room (not to mention <br>
the fact that the cealing is more than 29' away, even if I'm standing directly <br>
under it)<br>
<br>
Then there's the fact that not everything is inside.<br>
