Abstract:
A method, an apparatus, and a computer program product for inductive communication are provided in connection with providing mechanisms for detecting a remote NFC device without excessive power consumption. In one example, a communications device is equipped to monitor frequency oscillations associated with a NFC antenna using a calibrated LPO, 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.
