> Are you sure? According to wiki, there are plenty allowed 5GHz channels in Turkey.

Pretty, yeah. Doesn't the same wiki page list a bunch of not-allowed 5Ghz channels too? Or only allowed ones?

I didn't mean to claim it's completely banned, but some channels are, which leads to some hardware makers to just eschew the entire 5Ghz stuff instead of just specific channels, like what this submission is about.
