A single host device, comprising a plurality of Bluetooth devices, estimates bandwidth requirements such as maximum rates and/or an average data rate expected by each of a plurality of Bluetooth applications to be run on the single host. For each Bluetooth device, available frequencies utilized are determined based on the estimated bandwidth requirements. Each of the plurality of Bluetooth applications is allocated to corresponding one or more Bluetooth devices based on the determined available frequencies so as to, for example, concurrently run corresponding Bluetooth applications on the single host. The determined available frequencies are assigned to corresponding Bluetooth devices based on the estimated bandwidth requirements. The determined available frequencies and the plurality of Bluetooth applications may be reassigned and reallocated, respectively. Each of plurality of Bluetooth applications is allocated to the corresponding one or more Bluetooth devices based on the assigned/reassigned available frequencies and/or the estimated bandwidth requirements.
