Abstract

A method, comprising: receiving during a wideband reception period and by a wideband reception circuit of a first wireless transceiver a wideband ranging message; transmitting during a wideband transmission period and by a wideband transmission circuit of the first wireless transceiver a wideband ranging response message; receiving by a narrowband reception circuit of the first wireless transceiver received narrowband messages; and transmitting by a narrowband transmission circuit of the first wireless transceiver transmitted narrowband messages.

Claims

1. A method, comprising:

receiving during a wideband reception period and by a wideband reception circuit of a first wireless transceiver a wideband ranging message;

transmitting during a wideband transmission period and by a wideband transmission circuit of the first wireless transceiver a wideband ranging response message;

receiving by a narrowband reception circuit of the first wireless transceiver received narrowband messages; and

transmitting by a narrowband transmission circuit of the first wireless transceiver transmitted narrowband messages.

2. The method according to claim 1 further comprising:

receiving a received narrowband message that comprises an indication about a future transmission of the wideband ranging message; and

causing the wideband reception circuit to search for the wideband ranging message within the wideband reception period that is defined in response to the indication.

3. The method according to claim 2 comprising closing the wideband reception circuit outside the wideband reception period.

4. The method according to claim 2 comprising starting wideband reception period after a predetermined delay period lapsed from the receiving of the received narrowband message that comprises the indication.

5. The method according to claim 2 wherein the indication comprises timing information about timing of the wideband reception period.

6. The method according to claim 2 comprising closing the wideband transmission circuit outside the wideband transmission period.

7. The method according to claim 2 wherein the indication further comprises at least one wideband reception parameter associated with a reception of the wideband ranging message.

8. The method according to claim 2 wherein the wideband ranging response message comprises timing information about a time difference between the receiving of the wideband ranging message and the transmitting of the wideband ranging response message.

9. The method according to claim 2 wherein the wideband ranging message is transmitted by a second wireless transceiver and wherein the response message comprises timing information about an estimated time difference between a transmission of the wideband ranging message by the second wireless transceiver and a reception of the wideband ranging response message by the second wireless transceiver.

10. A non-transitory computer readable medium that stores instructions that when executed by a computer cause the computer to execute the stages of:

receiving during a wideband reception period and by a wideband reception circuit of a first wireless transceiver a wideband ranging message;

transmitting during a wideband transmission period and by a wideband transmission circuit of the first wireless transceiver a wideband ranging response message;

receiving by a narrowband reception circuit of the first wireless transceiver received narrowband messages; and

transmitting by a narrowband transmission circuit of the first wireless transceiver transmitted narrowband messages.

11. A wireless tag that comprises a wireless transceiver that comprises a wideband reception circuit, a narrowband reception circuit, a wideband transmission circuit and a narrowband transmission circuit;

wherein the wideband reception circuit is arranged to receive during a wideband reception period a wideband ranging message;

wherein the wideband transmission circuit is arranged to transmit during a wideband transmission period a wideband ranging response message;

wherein the narrowband reception circuit is arranged to receive narrowband messages; and

wherein the narrowband transmission circuit is arranged to transmit transmitted narrowband messages.

12. The first wireless transceiver according to claim 11 wherein the narrowband reception circuit is arranged to receive a received narrowband message that comprises an indication about a future transmission of the wideband ranging message;

and wherein the wideband reception circuit is arranged to search for the wideband ranging message within the wideband reception period that is defined in response to the indication.

13. The wireless tag according to claim 12 that is arranged to close the wideband reception circuit outside the wideband reception period.

14. The wireless tag according to claim 12 that is arranged to start the wideband reception period after a predetermined delay period lapsed from the receiving of the received narrowband message that comprises the indication.

15. The wireless tag according to claim 12 wherein the indication comprises timing information about timing of the wideband reception period.

16. The wireless tag according to claim 12 that is arranged to close the wideband transmission circuit outside the wideband transmission period.

17. The wireless tag according to claim 12 wherein the indication further comprises at least one wideband reception parameter associated with a reception of the wideband ranging message.

18. The wireless tag according to claim 12 wherein the wideband ranging response message comprises timing information about a time difference between the receiving of the wideband ranging message and the transmitting of the wideband ranging response message.

19. The wireless tag according to claim 12 wherein the wideband ranging message is transmitted by a second wireless transceiver and wherein the response message comprises timing information about an estimated time difference between a transmission of the wideband ranging message by the second wireless transceiver and a reception of the wideband ranging response message by the second wireless transceiver.
