First Claim
Patent Images
1. A method, comprising:
- determining whether to perform near-field communication (NFC)-type operations in a near-field mode or a far-field mode;
performing the NFC-type operations inside a near-field region using an NFC loop antenna when in the near-field mode;
performing the NFC-type operations outside the near-field region using a repurposed wireless wide area network (WWAN) antenna when in the far-field mode; and
performing, in response to determining the far-field mode, a packet arbitration procedure for WWAN communication and the NFC-type operations outside the near-field region.

Abstract
A method for performing near-field communication (NFC)-type operations in the far-field region using a repurposed antenna is described. The method includes determining whether to perform NFC-type operations in a near-field mode or a far-field mode. The method further includes performing NFC-type operations outside a near-field region using a repurposed antenna when in the far-field mode.
