Digitec's product description says that the U6+ has a single-band frequency band. I understand this to mean that it can only transmit/receive on 2.4GHz or 5GHz but cannot operate both in parallel, such as: Printer 2.4GHz and Laptop 5.0GHz. I did not find this information on the manufacturer's website. Now I am confused. Can anyone answer the question whether they can now operate both frequency bands in parallel?
