A system for managing the simultaneous operation of a plurality of radio modems in a single wireless communication device (WCD). The multiradio control may be integrated into the WCD as a subsystem responsible for scheduling wireless communications by temporarily enabling or disabling the plurality of radio modems within the device. The multiradio control system may comprise a multiradio controller (MRC) and a plurality dedicated radio interfaces. The radio interfaces are dedicated to quickly conveying delay sensitive information to and from the radio modems. The modems may further include control features that take information from the MRC as an input in determining the priority of messages to be sent out to a receiving device.
