yikes!

-> Bad idea unless we put a tube between point A and B and let the  
antennas talk directly to each other thru the tube ;-))
Wait! Wasn't that called coax cable back then ? ;-) Ok... let's get  
serious again.

Funny coincidence: just yesterday I finally got the ubiquiti sr71-a  
cards. And I think I got them somewhat working on openwrt. AP mode  
does not work yet, but ad-hoc seems to work. Still need to do stress  
tests.  I will see more on the weekend but if it works, we will also  
have an open source 802.11n solution.

Going back to the interference issues with N:
Do you think that this basically will exclude us from using 802.11n ?  
AFAIK now they use channel bonding and therefore there is not enough  
space for others. So, it would be a property of the N standard and not  
of the particular cards/OS, right?
Does anyone know more about spectral behavior of N?
