Most wireless networks will not see the effect of co-channel interference and degradation from neighboring networks unless they are moving serious amounts of traffic. Remember the Network Computing's tests used Chariot to fill the pipe.
So just because you haven't seen a problem in your deployments doesn't mean it's not happening, it's just more likely that it's not noticeable in casual-use networks. And even if you did try to systematically evaluate the performance of those APs that 'touch' neighboring wireless networks, the existence of your own production traffic and neighboring APs would make it difficult to tease out the specific causes.

It's always good to know what to keep an eye out for when you're designing something. We're not seeing problems in our still Cisco buildings that are near Meru buildings that we are aware of, and the users are pretty good at telling us if it quits working. > > If there's a silver lining here, it may be that 11n is likely to > push most enterprises towards more pervasive 5 GHz deployments, > where co-channel interference is not such a big issue. > > dm > > ----- -debbie Debbie Fligor, n9dn Network Engineer, CITES, Univ. of Il email: [EMAIL PROTECTED] <http://www.uiuc.edu/ph/www/fligor> "My turn." -River ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
