(StringTypeLink["FrequencyAllocation", paclet:ref/entity/FrequencyAllocation]) entities represent particular, named sections of the electromagnetic spectrum.

Some properties are available for the (StringTypeLink["FrequencyAllocation", paclet:ref/entity/FrequencyAllocation]) entity type as a whole and can be given using the form (RefLink[EntityValue, paclet:ref/EntityValue])[(StringTypeLink["FrequencyAllocation", paclet:ref/entity/FrequencyAllocation]),property]. Such properties include:

The following annotations can be used in the third argument of (RefLink[EntityValue, paclet:ref/EntityValue])[(StringTypeLink["FrequencyAllocation", paclet:ref/entity/FrequencyAllocation]),property,annotation]:

The following annotations can be used in the second argument of (RefLink[EntityValue, paclet:ref/EntityValue])[property,annotation]:

A qualifier value of (RefLink[Automatic, paclet:ref/Automatic]) indicates that an applicable format of values can be used; e.g. for the "Date" qualifier, this includes a proper date or date span.
