I'm responding to the question about why you might split SSIDs. SSIDs don't have anything to do with frequency necessarily, morso network segregation.

Yes. Old devices can only use limited data rates and they will drag down the throughput of other devices on the same channel. Some controllers or APs allow you to limit to lowest data rate you will accept a connection from.

Sure, I was only talking about splitting by bands as I thought that's what this entire conversation is about. Of course there are plenty other reasons to have more than one network in the world :)
> Old devices can only use limited data rates and they will drag down the throughput of other devices on the same channel.
They will do so regardless of which AP or SSID they are connected to, though, as the channel is a shared physical medium.
If the goal is to isolate slow/old devices from modern ones, that can be done regardless of the band.

In a multi-ap setup you can isolate those 2.4ghz devices to their own, short range said that allows very permissive datarates. Then everything else gets 5ghz or 6ghz with mediumish output power and restricting the lower data rates. This prevents clients that move to the edge of the coverage zone from hitting lower data rates and dragging the whole channel or SSID or both down.
It just depends on your setup, number of APs, type of devices, device demands, etc.
