+Radio Settings hierarchy
+========================
+
+Service org.ofono
+Interface org.ofono.RadioSettings
+Object path [variable prefix]/{modem0,modem1,...}
+
+Methods dict GetProperties()
+
+ Returns all radio access properties. See the
+ properties section for available properties.
+
+ Possible Errors: [service].Error.InvalidArguments
+
+ void SetProperty(string name, variant value)
+
+ Changes the value of the specified property. Only
+ properties that are listed as read-write are
+ changeable. On success a PropertyChanged signal
+ will be emitted.
+
+ Possible Errors: [service].Error.InvalidArguments
+ [service].Error.DoesNotExist
+ [service].Error.InProgress
+
+Signals PropertyChanged(string property, variant value)
+
+ This signal indicates a changed value of the given
+ property.
+
+Properties string Mode [read-write]
+
+ The current radio access selection mode, also known
+ as network preference.
+
+ The possible values are:
+ "dual" Radio access selection is done
+ automatically, using either 2G
+ or 3G, depending on reception.
+ "2g" Only GSM used for radio access.
+ "3g" Only UTRAN used for radio access.
+ "unknown" Mode currently unknown.
