1. A method of wireless communications, comprising:

  • sensing an operating volume for a presence of a field generated by a remote near field communication (NFC) device as part of an active communication mode collision avoidance procedure;

    determining that no field is sensed within the operating volume of an NFC device;

    initiating an unmodulated carrier as part of switching an operating field for the NFC device to an on state; and

    maintaining the unmodulated carrier for a collision avoidance threshold duration of time.
