Abstract
A wireless communication device comprises a control unit, an antenna interface, an active wireless transceiver operable together with the control unit and antenna interface, a passive wireless transceiver operable together with the antenna interface and operable by harvesting power from received radio messages. The device is further configured to deactivate the one or more active wireless transceivers and control unit to an inactive state and, subsequently, by the passive wireless transceiver, activate the control unit and an active wireless transceiver to an active state when the passive wireless transceiver receives a message from the antenna interface.

-15. (canceled)
A wireless communication device comprising:
- a control unit;
- and
- an antenna interface;
- and
- one or more active wireless transceivers operable together with the control unit and antenna interface;
- and
- a passive wireless transceiver operable together with the antenna interface and operable by harvesting power from received radio messages;
- and wherein the device is further configured to:
- deactivate the one or more active wireless transceivers and control unit to an inactive state;
- and
- subsequently, by the passive wireless transceiver, activate the control unit and at least one of the active wireless transceivers to an active state when the passive wireless transceiver receives a message from the antenna interface.
A computer-implemented method for managing a wireless communication device;
- the wireless communication device comprising:
- a control unit,
- an antenna interface,
- one or more active wireless transceivers operable together with the control unit and antenna interface,
- a passive wireless transceiver operable together with the antenna interface and operable by harvesting power from received messages;
- and
- wherein the device is further configured to:
- deactivate the one or more active wireless transceivers and control unit to an inactive state;
- and
- subsequently, by the passive wireless transceiver, activate at least one of the active wireless transceivers and control unit to an active state when the passive wireless transceiver receives a message from the antenna interface and stores the message in a memory;
- and
- wherein the method comprises the following steps performed by the control unit:
- upon activation, reading a configuration field of the message from the memory;
- and
- configuring the device according to the configuration field.
