Abstract

Power levels for transmitting Bluetooth paging signals are optimized by applying mapping rules dictating different power levels for different signal quality characteristics measured during an earlier, pre-paging inquiry process. A subject Bluetooth device initially receives responses to universally addressed, blind inquiry signals previously broadcast by the subject Bluetooth device. In response, the subject Bluetooth device measures signal quality characteristics of each device's response. When a Bluetooth device to be paged is identified, the subject Bluetooth device applies the mapping rules to the measured signal quality characteristics for the identified device to select an appropriate power level for use in paging that Bluetooth device.
