Abstract

A system for managing the operation of one or more of wireless communication mediums supported by one or more radio modules integrated within a WCD. A control strategy may be employed to evaluate and manage pending communication activity down to the wireless message stream level through the creation of operational schedules. The operational schedules may be utilized by the one or more radio modules in the WCD in order to determine how resource usage should be allocated for supporting the communication activities conducted over a radio module.
