Abstract
Bandwidth management techniques are provided for use in heterogenous wireless personal communications systems, designed minimize or eliminate interference between different personal communications units. Such units may be of various types including, for example, hearing health care units, telecommunications headsets and multimedia headsets. A bandwidth resource is shared among multiple autonomous communications systems in which a Remote Processing Unit and headset pair are coupled by a slotted wireless communications link. One of a pair of devices transmits real-time information to the other device of the pair. When difficulty is experienced receiving the real-time information because of interference from a different device pair, any of several different measures may be applied including physical adjustments such as (in an RF system) diversity and/or power control. If these adjustments are insufficient, a jump procedure may be performed in which the pair of devices jump to a different portion of the bandwidth resource determined to be free. A first negotiation procedure may be performed in which the Remote Processing Unit aligns its timebase to that of a selected other Remote Processing Unit; or a second negotiation procedure may be performed in which the Remote Processing Unit and the headset agree to cease exchanging audio information within one or more particular timeslots.
