AIXM 5 defines the class RadioCommunicationChannel as follows:
A radio frequency band of sufficient width and associated identification data used for one- or two-way communication from or to a transmitter on the ground or in the air.
Basically, a RadioCommunicationChannel is used by a Service or a NavaidEquipment.
The main attributes of the RadioCommunicationChannel are the frequency or channel or logon address on which the Service or the Navaid is transmitting and can be received.
- for one way broadcast (e.g. ATIS);Â frequencyTransmission is coded
- for two-way radio communication on the same frequency (single channel simplex); both frequencyTransmission and frequencyReception contain the same value
- for two-way radio communication on two distinct frequencies (double channel simplex, offset frequency simplex, duplex); frequencyTransmissioncontains the transmission frequency and frequencyReception contains the reception frequency (as seen by the service provider).
The RadioCommunicationChannel.rank attribute can be used indicating the role of the communication channel, in terms of primary, alternate, emergency, etc.
The RadioCommunicationChannel may have also an associated schedule, which indicates the usage time of that particular communication frequency or channel.
