1. A security control module for controlling access through a passageway of a secure control area, the security control module comprising:
an ultra-wideband transceiver configured to establish an ultra-wideband transmission with an ultra-wideband communication module of a mobile device; and
a processing unit configured to determine a first distance between the security control module and the mobile device by processing signal properties of the ultra-wideband transmission,
the security control module being configured to receive a second distance from a further security control module arranged at a spacing distance apart from the security control module, the second distance being indicative of a distance between the further security control module and the mobile device,
the security control module being further configured to transmit the first distance to the further security control module, and
the processing unit being configured to determine the relative position of the mobile device with respect to the security control module based on the first distance and the second distance.
