Abstract
A system for managing the operation of a plurality of radio modules integrated within the same wireless communication device. In at least one embodiment of the present invention, time may be allocated for use in communicating over one or more wireless communication mediums. This time may be allocated based on a determination that a maximum power usage threshold will not be exceeded, and that potential communication conflicts may be avoided, over a period of time. The allocation may result in an operational schedule that may be utilized by radio modules in the wireless communication device that support the one or more wireless communication mediums.
