Are you referring to the software part of the product description(RAK7289V2/RAK7289CV2 WisGate Edge Pro | RAKwireless Documentation Center)? If so I need to tell you this is a misunderstanding and we will fix the docs as soon as possible to bring some clarification. This is an optional feature of the software, but only the hardware supports it, which is not the case with the RAK7289. Apologies for the inconvenience!
