Abstract

A system for managing the operation of a plurality of wireless communication mediums supported by one or more radio modules integrated within a wireless communication device. A control strategy may be employed to regulate the operation of at least one wireless communication medium operating in a continuous mode, such as an discovery or inquiry mode, so as not to conflict with other active communication occurring substantially simultaneously within the wireless communication device. The regulation may occur in the one or more radio modules, and may include rescheduling part of, or alternatively a whole, discovery hop train.
