In Steamers at Wokingham station today. Here is a well allocated WiFi spectrum. All overlapping channel usage is "co channel". 1, 6 and 11. No "distorting" "adjacent channels" are present.
My main unanswered question is so what? These overlapping co channels are fully distorting if there are competing co channels present. Fully overlapping.
Whereas a partially adjacent channel would be less distorting by the amount it is not overlapping, all else being equal.
Can anyone tell me why co channel is better than adjacent channel, as it seems is the commonly accepted design practice, given competing channels may be present?
This is relevant in political economy. Radio spectrum is economic land. What wealth is made using it and how that is distributed among its users, forms the basis of everything else.
