The Service will be provided by a Unit. At least the Unit.name has to be provided.

The Service will use one or more RadioCommunicationChannel. At least the RadioCommunicationChannel.frequencyTransmission, and in case of bidirectional communication also the RadioCommunicationChannel.frequencyRecpetion has to be coded.

Subsequently, the encoded Service is related to the HoldingPattern it controls or concerns.
