Yeah, not sure if author knows, they certainly don't share if they understand this or not, but these things aren't available because the some governments say those frequencies are illegal to use. Turkey for example has multiple frequencies under 5Ghz WiFi that is banned, hence consumer don't get to use 5Ghz WiFi. If you change that, you're breaking the law and you might get a visit, depending on how hardcore they are about the rules. Tend to be pretty strict and swift payback when it comes to using frequencies you shouldn't, as they're used for other stuff and easily seen when other traffic appears.

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

		> 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.

		In addition to the other (great) reply pointing out the difference between 5G and 5Ghz, there is also the nuance of channels within the 5Ghz band. While the band may be lawfully used within a region, some channels within that band may be banned. So it’s not enough to say “we have 5Ghz wifi here so it’s fine” because there are many channels within that band which may not all be treated equally.

		5G the cellular connection, or 5GHz bands for wifi? GP was talking about wifi.
