There seems to conflicting or inconclusive information the topics below. I have just been readying various docs using google searches. I am hoping to get some solid answers.
1) What channels for 802.11a are really non-overlapping? 8 or 12? I have read in some sources that it is 12 but the last 4 are for outdoor use(?).
2) in regards to 802.11a, channels 149 - 165 are considered for outdoor use so indoor availability is only 8 channels, correct?
3) What would be the non-overlapping channels for 802.11n? Indoor use only.
4) What happens when an 802.11n/a device and a traditional 802.11a device connect to the same network?
