First Claim
1. A radio communication system, comprising:
- a system computer;
a radio communication device comprising a radio communication antenna;
an audio management system;
a user communication device connected to the audio management system; and
a data bus connecting the system computer, the radio communication device and the audio management system;
wherein said system computer is arranged to switch between a data communication service and a voice communication service upon receiving a signal from the radio communication device indicating that a carrier on a predetermined fixed frequency has been detected or has ceased to be detected by said radio communication device, or from the audio management system indicating that a request for a predetermined fixed frequency voice communication service has been detected or has ceased to be detected by said audio management system.
