  • Publication number: 20030139136
    Abstract: Transmissions of a Bluetooth device are optimized to overcome signal interference. Mapping rules dictate different Bluetooth packet types to be used for transmission under various specified conditions including prescribed signal interference characteristics. The Bluetooth device measures signal interference characteristics upon different Bluetooth frequencies. The Bluetooth device identifies messages pending transmission to one or more remote Bluetooth devices, and receives designation of frequencies to be used in transmitting the pending messages to the remote Bluetooth device according to a predetermined frequency hopping scheme. The Bluetooth device applies the mapping rules to conditions including at least the measured signal interference characteristics for the designated frequencies to select Bluetooth packet types for use in transmitting the identified messages to the remote Bluetooth device.

  • Publication number: 20030036354
    Abstract: In a dual mode Bluetooth/wireless mobile unit, the next sleep mode Bluetooth wakeup time is rescheduled to synchronize with any upcoming idle mode wireless wakeup time that will otherwise precede the Bluetooth wakeup time. The Bluetooth clock is advanced, or other reconfiguration made to the Bluetooth module, as appropriate to prevent the scanning frequency from changing during a sleep mode Bluetooth wakeup/scanning interval commencing at the resynchronized Bluetooth wakeup time.

  • Publication number: 20030036416
    Abstract: Method for reducing power consumption in Bluetooth and CDMA modes of operation is disclosed. According to a disclosed embodiment, the time for a next scheduled CDMA wakeup process to be performed by a CDMA module is established. Thereafter, if the next CDMA wakeup process is scheduled to be performed before the next Bluetooth wakeup process, a Bluetooth wakeup process is synchronized to be performed by a Bluetooth module at the same time as the next CDMA wakeup process. Following, when the time arrives for the CDMA module to perform the next CDMA wakeup process, the Bluetooth module also performs the Bluetooth wakeup process.
