Abstract
Example method, apparatus, and computer program product embodiments are disclosed to improve device discovery in near-field communication. Example embodiments of the invention include a wireless host device coupled to a near-field communication (NFC) controller via an NFC controller interface (NCI), the NFC controller capable of exchanging NFC radio frequency (RF) signals with other NFC controllers or with NFC tags, according to an embodiment of the present invention. In example embodiments of an NFC discovery RF signal sequence may be exchanged between two NFC controllers, each sequence of RF signals comprising a plurality of discovery periods including a poll interval, a listen interval, and an idle interval. Several methods are disclosed to improve the probability of detection of another NFC device by modifying the format of the discovery period.
