In the options for the Mini 2's wifi, it lists 2.4Ghz, 5Ghz, and 5.8Ghz. Now, I understand 2.4Ghz vs 5Ghz wifi, but never heard of 5.8Ghz wifi. What is the difference between 5Ghz and 5.8Ghz wifi? In what circumstances should the 5.8Ghz option be chosen? I assume the phone running the VIofo app needs to be able to support 5.8Ghz wifi. I'm not sure, but is 5.8Ghz the same as the Wifi 6 standard?
