Hi! I guess you're planning a two.radio mesh to improve troughput. I recently went trough a similar experience and learnt thanks to this list, turns out, this might sound counterintuitive at first, but in some setups, using just 2 channels, spaced further apart, will avoid interference better than 3 ('almost') overlapping channels. I.e. Using channel 1 and 11 works better than 1 and 6.
I'm assuming you're not using 5.8g , etc
I suggest you to check a thread on this list last month archives, 'bandwidth degradation on p2p links', there are some interesting references to read on the subject.

Hi guys. I’m trying to make a for nodes WMN using four devices with two wireless cards each. I would like to use three different channels to reduce the interference, like this: [Node A] <- channel 1 -> [Node B] <- channel 2 -> [Node C] <- channel 3 -> [Node D] First I configure eight wireless cards to the specific channel in ad-hoc mode using “iw dev wlan0 ibss join …”. Then, I think I should add wlan0 and wlan1 to the same batman-adv interface (that is bat0) in every device. So I need to configure four nodes with the same commands like: echo bat0 > /sys/class/net/wlan0/batman_adv/mesh_iface echo bat0 > /sys/class/net/wlan1/batman_adv/mesh_iface Last configure an IP address to each bat0. (Node A-10.0.0.1, Node B-10.0.0.2, Node C-10.0.0.3, Node D-10.0.0.4). But it seem Node A can reach Node B and Node C(using ping), but can’t for Node D.
Am I following the right procedure? Sorry for my poor English. Any help would be appreciated.
Puyou Lu.
