Abstract: Systems and methods which utilize wireless charging to initiate near field communication (NFC) pairing between mobile systems which utilize wireless charging and wireless charging base stations. Wireless signals sent by a mobile system over a wireless charging channel are used to initiate communication between an NFC reader presented in a base station and a passive NFC tag (or an active NFC tag used in a passive mode) present in the mobile system. Such feature allows the mobile system to act as an initiator for NFC communication without requiring the mobile system to be equipped with an NFC reader. A wireless power receiver of a mobile system may communicate with a wireless power transmitter of a base station using backscatter modulation. Commands of a standard wireless charging protocol may be repurposed to send a request for initiation of an NFC session from a mobile system to a base station.

Abstract: Systems and methods which allow for the coexistence of wireless charging (WCH) and short-range communication (e.g., NFC) in a close spaced relationship. A cradle may include a plurality of slots which each removably receive one of the mobile systems. The cradle and the mobile systems may each include NFC and WCH coils that are closely spaced but are placed orthogonally relative to each other. A time multiplexer may be used to disconnect WCH while performing NFC communication to prevent crosstalk in the same mobile system. A filtering system may act on the NFC circuits to allow contemporary activation of WCH and NFC communication on mobile systems. A slot multiplexer may be provided in the cradle to allow for selection of a single mobile system slot at a time to activate NFC communication with the mobile systems, using a single NFC communication controller for all of the mobile system slots.
