Question : Acceptable signal to noise ratio...

Hello everyone.  I'm sure this will be more of an opinion based answer, but here goes:  I work for a local school system and we are currently trying to make some of the high schools completely wireless.  We've taken our WAPs up to our different halls and tried different placement just to see what kind of numbers we get (using a program called NetStumbler v3.01 I believe if that matters).  I was mainly just wondering what others have decided to use as their "acceptable" signal to noise ratio - of course we all want it to be next to nothing, but we're on a budget!  Any thoughts would be appreciated.

Thanks.

Answer : Acceptable signal to noise ratio...

Yea, its just a rule. It can be broken.  It just depends on the amount of funds available for a project. 32 might be high. But it is not a must.  Data quality is really only effected up to a 20 SNR.  Above that the effect is minimal. I just like to give it room for a cloudy day. Literally. Clouds effect signal. Water in the clods.  Also the 32 takes in to effect a slient with a sub-par card.  

I never caught what freq. yo were using? 2400mhz or 5800mhz ?  Other?

Regards.
