They have different SSID's so by nature you can limit devices to a single band.

They however do not offer band steering (which is an essential feature for dual band AP's IMHO) but then again no home routers do no matter the price.

I've got my 5GHz-capable devices only using that by going through device, has helped clear some Wi-Fi noise as 2.4 being used by wireless phone.

Change the SSID's so they are both different. Then you select the network on your phone to connect to. AFAIK you cant have an individual password for each SSID.
