It doesn't need high bandwidth, does it?

So, 2.4GHz would give better coverage.

It's because of the chipset used. ESP 32 only does 2.4GHz.

Yeah.

But I meant that 5GHz is not needed at all.

It could even be worst if it supported it and switched to using 5GHz, because it would have worst coverage.

IMHO. Not needed. Yes.
