Abstract: A first component (CMP1) is connected to the antenna (ANT) and to an impedance matching circuit (CAI) configurable on command and connected to the antenna, and in the absence of another component (CMP2) connected to the antenna, the impedance matching circuit is placed in a first configuration in which it forms with the first component and the antenna a resonant circuit having a first resonant frequency compatible with a carrier frequency. In the presence of a second component (CMP2) connected to the antenna, the impedance matching circuit is placed in a second configuration in which it forms with the first component, the second component and the antenna a resonant circuit having a second resonant frequency compatible with the carrier frequency.

Abstract: A device includes near-field communication (NFC) control circuitry and transceiver circuitry. The transceiver circuitry is coupled to the NFC control circuitry. In a reader mode of operation, the NFC circuitry detects reception of NFC polling frames by the transceiver circuitry. When reception of an NFC polling frame is detected, the NFC control circuitry switches from the reader mode of operation to a card mode of operation.

Abstract: Devices and methods for configuration of a mobile terminal including a near-field communication device and a radio communication device separate from the near-field communication device are provided. One such method includes determining, by the radio communication device, an identifier of a wireless local network within a range of the mobile terminal. The method further includes selecting, from a configuration table, at least one configuration parameter of a plurality of sets of configuration parameters of the near-field communication device according to the identifier, and applying the at least one configuration parameter to the near-field communication device.
