The additional 5GHz channels and changes in requirements to use them can easily be supported on existing Aruba AP platforms through our DRT mechanism. As soon as we obtain the/updated certs, we can push out a new DRT version to enable the new capabilities. After that it is ultimately up to our customers to decide whether or not to enable these channels. Keep in mind that if client devices do not (yet) support them, these devices could be experiencing coverage holes in an enterprise system where the channels are used.
6GHz support is a completely different situation. First of all, support requires new chipsets, new radios, and new access point platforms. Also, for the same reason as above (client support), 6GHz support will need to be "in addition to" concurrent 2.4GHz and 5GHz support. It basically provides a "third spectrum layer", delivering a massive increase in Wi-Fi capacity. The typical 6GHz capable enterprise AP will be a tri-radio device.
That's a long way to answer "no" to your question about 6GHz support (and "yes" for 5GHz).
