Access points 3802i coverage distance

[mehranb]

Hello there,

I'm looking for some information on the coverage distance of Cosco Aironet 3802i and Aironet 1570.

Questions like these lead to 100% failure. Better get someone in to do a proper WLAN design.

No one in this forum is dumb and irresponsible enough to answer a fully loaded question like that.  

Get a wireless site survey/design done properly or provide more reliable information.

please refer to Cisco Aironet 1570 Deployment Guide

It appears @mehranb provided the raw numbers but what @Karsten Iwen and @Leo Laohoo are telling you, those numbers are almost meaningless in real world WLANs.  There are many possible impediments to AP coverage distance.  Further wireless performance is also impacted by other active wireless hosts.  I.e. a wireless host can receive poor service even with 10 meters and a direct line of sight.

Three weeks ago, I attended Cisco Live and went into a Breakout Session about tips-n-tricks about WiFi placement and design.  The speaker has seven tips and in Tip #1 answers the question about "how far should APs be positioned" and she put a number.  That was it.  

And the crowd "tore her to shreds".  The speaker completely lost the crowd  -- The number was so vague that a-truck-could-drive-through.  

@mehranb, just about anyone can easily make a bad wireless design (cheaply), however, the "big money" is fixing someone's bad wireless placement design.
