I just blundered across this paper on 802.11n interference: "802.11n Under the Microscope" <http://pages.cs.wisc.edu/~shravan/11n.pdf> Apparently, it doesn't take much to mangle 802.11n without or without channel bonding. We show that the throughput of an 802.11n link can be severely degraded (up to 85%) in presence of an 802.11g link. Our results also indicate that increased amount of interference due to wider channel bandwidths can lead to throughput degradation. In other words, just about any form of interference will trash 802.11n thruput. Most of the N boxes I've played with will revert to the slower 802.11g speeds at the first hint of any co-channel users (interfering or not including adjacent channel spillover). -- Jeff Liebermann jeffl(a)cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
