One of the transceiver units receives in a predetermined ranging session a time signal from an external device unit, which time signal comprises a device clock state of the device unit at a reference time in a device time zone. The receiving transceiver unit generates a synchronization dataset describing a time relationship between an apparatus clock state at the reference time in the apparatus time zone and the device clock state at the reference time in the device time zone. The receiving transceiver unit initiates a synchronization session, in which the receiving transceiver unit defines a synchronization time grid which has a periodically repeating synchronization block, which provides a session round. In a predetermined session slot of the session round of the periodically repeating synchronization block, the receiving transceiver unit transfers the synchronization dataset to the others of the transceiver units.
