There is no "1, 6, 11" anymore. You're not listening. Back in the day, the adjacent (1 on 6, 6 on 1, 11 on 6, 6 on 11) channel rejection spec for 802.11b was 35dBm at 11Mbps modulation There never was an alternate (1 on 11, 11 on 1) channel rejection spec in the days of 802.11b. Most decent sup

No, I get this bit. Totally. I had to deal with this with HT40 channels where .. the rejection isn't as great. Adjacent channel interference into the secondary channel just killed things. I'm right now more interested in making sure we can gather the data we need first. The channel selection bit i

Yes, the interference can be calculated by averaging the beacon RSSI (dB) of the overlapping channels, e.g. for channel 6, the beacon RSSI of channels 4, 5, 6, 7, 8 are averaged. Normally channels 1, 6, and 11 are chosen, although other channels may have less interference, in order to be a 'good ne

Hi Adrian, I'd be happy to work on it. What is the SVN URL to check out and commit? My router is OpenWrt compatible. Is that good enough? Yes, the metric involves interference and noise floor. Thanks for your help, Tek Wiz On Wed, Dec 4, 2013 at 9:56 AM, Adrian Chadd wrote: > >> On 3 Decem
