METHODS AND APPARATUS FOR IMPROVING REMOTE NFC DEVICE DETECTION USING AN OSCILLATOR CIRCUIT |
摘要 |
A method, an apparatus, and a computer program product for wireless and/or inductive communications are provided in connection with improving remote NFC device detection through use of an oscillator circuit connected to an NFC antenna and matching network. In one example, a communications device is equipped to monitor frequency oscillations generated by an oscillator circuit associated with a transmitter path of a NFC antenna and matching network, determine that a number of occurrences of the frequency oscillations from a reference frequency is greater than a frequency deviation threshold, and perform a NFC polling procedure in response to the determination. |

1. A method of inductive communications, comprising:
monitoring frequency oscillations generated by an oscillator circuit associated with a transmitter path of a near field communication (NFC) antenna and matching network; determining that a number of occurrences of the frequency oscillations from a reference frequency is greater than a frequency deviation threshold; and performing a NFC polling procedure in response to the determination. |
