A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. A control strategy may be employed to manage both more predictable and more spontaneous wireless communication mediums, wherein a local controller may be employed in a radio module utilizing an unscheduled wireless medium, like WLAN, for determining whether adequate time has been allocated to complete a transaction. If the transaction cannot be completed in the allowed time, it may be delayed until adequate time exists, and the delay may be reported so that the time may be reallocated to other radio modules. The radio module may then enter a power-saving mode until the transaction can be completed.
