  • MOBILE WIRELESS COMMUNICATIONS DEVICE HAVING NFC SENSOR AND MAGNETIC SENSOR AND ASSOCIATED METHODS
    Publication number: 20130143486
    Abstract: A mobile wireless communications device includes a near field communications (NFC) device, and a magnetic sensor. A processor is coupled to the NFC device and the magnetic sensor, and is switchable between an active mode and an idle mode based upon the magnetic sensor. The processor is configured to remain in the active mode based upon communication via the NFC device irrespective of the magnetic sensor.

  • MOBILE WIRELESS COMMUNICATIONS DEVICE HAVING A SINGLE BLUETOOTH / WIRELESS LOCAL AREA NETWORK ANTENNA AND ASSOCIATED METHODS
    Publication number: 20120106525
    Abstract: A mobile wireless communications device includes a wireless local area network (WLAN) radio configured to generate a WLAN transmit signal, and a Bluetooth radio configured to generate a Bluetooth transmit signal. A circulator is coupled downstream of an antenna. A transmit path couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously. In addition, a receive path also couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously.
