Now, it can also run in the 2.4 gigahertz band, but not for 802.11ac. This wireless access point right here has three antennas for n and three antennas for ac.

Why anyone would do that, but you could. So, it has the ability of backward compatibility, but simply by making a better access point, not because 802.11ac itself does it, so be sure you're comfortable with that difference.
