Abstract
Data exchanges between an ultra-wide band communication module and a secure element are controlled such that the data exchanges pass through a near-field communication router. The near-field communication router controls routing of the data exchanges so that the data exchanges do not pass through a host circuit that is also coupled to the near-field communication router.
Claims26
A device, comprising:
- a near field communication router including a first port, a second port and a third port;
- an ultra-wide band communication module coupled for data communication over a first bus connected to the first port of the near field communication router;
- a host circuit coupled for data communication over a second bus connected to the second port of the near field communication router;
- and
- a secure element coupled for data communication over a third bus connected to the third port of the near field communication router;
- wherein data exchanges between the ultra-wide band communication module and the secure element pass through the near field communication router between the first and third ports connected to the first and third buses, respectively, and without passing through the second port, second bus and the host circuit.
A device, comprising:
- a near field communication router;
- an ultra-wide band communication module coupled for data communication to the near field communication router over a first bus;
- a host circuit coupled for data communication to the near field communication router over a second bus;
- and
- a secure element coupled for data communication to the near field communication router over a third bus;
- wherein the near field communication router includes routing means for controlling data exchanges between the ultra-wide band communication module and the secure element without passing through the host circuit, said routing means comprising:
- a communications bus;
- a first port coupling the communications bus to the ultra-wide band communication module;
- a second port coupling the communications bus to the secure element;
- and
- a third port coupling the communications bus to the host circuit;
- wherein the transmission of the data exchanges is controlled so as to not pass through the third port.
A method of managing data exchanges between an ultra- wide band communication module and a secure element, wherein said data exchanges pass through a near-field communication router without passing through a host circuit coupled to the near-field communication router, wherein the near-field communication router includes a first port coupled to the ultra-wide band communication module, a second port coupled to the secure element, and a third port coupled to the host circuit, said method further comprising controlling transmission of said data exchanges so as to not pass through the third port.
A method of managing data exchanges between an ultra-wide band communication module and a secure element, wherein said data exchanges pass through a near-field communication router without passing through a host circuit coupled to the near-field communication router, wherein the near-field communication router includes a communications bus, a first port coupling the communications bus to the ultra-wide band communication module, a second port coupling the communications bus to the secure element, and a third port coupling the communications bus to the host circuit, said method further comprising controlling transmission of the data exchanges so as to not pass through the third port.
