+To see what frequency the radio is configured for, use the following command and example with channel=28 and op_class=71 in the host ap conf file:

+Note, some OS's will report the HaLow radio working over 5GHz due to the standard WiFi not being aware of sub-1GHz. 
+
+There are times that Linux can recognize the interface as a generic 5Ghz radio and allow you to configure it as an AP or a STA. Linux does not understand that the channels map to the sub-1GHz band. The bandwidths will map as follows:
+ - 20MHz = 1MHz sub-1G
+ - 40MHz = 2MHz sub-1G
+ - 80MHz = 4MHz sub-1G
+ - 160MHz = 8MHz sub-1G
