Abstract
A beacon transmitter device (BTD1; 700; 900) is disclosed. The beacon transmitter device comprises a controller (710; 910) and a short-range wireless beacon transmitter (732; 932). The controller is configured to cause a first transmission (S12) of a short-range wireless beacon signal (BA1) by the beacon transmitter, the beacon signal identifying a beacon region. The controller is also configured to wait during a beacon delay time period (BDTP), and then cause a second transmission (S32) of the short-range wireless beacon signal (BA1) by the beacon transmitter. The beacon delay time period (BDTP) is sufficiently long to allow a short-range wireless beacon receiver device (P1), when being in a passive mode, being in range of the beacon region and having received the first transmission of the beacon signal, to receive and react (S34) on the second transmission of the beacon signal.
