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 .
