1. A logistics system for construction units comprising:
one or more signal transmitters, each configured to be mounted on a construction unit and to provide identifying information related to the construction unit to which it is mounted, the identifying information comprising an electromagnetic signal; and
a signal evaluation device comprising one or more loop antennas, each loop antenna configured to:
receive the identifying information from a first signal transmitter of the one or more signal transmitters by detecting a magnetic component of the electromagnetic signal when the first signal transmitter is in proximity to the loop antenna; and
evaluate the received identifying information;
wherein the one or more loop antennas are positioned about a construction site; and
wherein the system detects the presence and position of construction units at the construction site.
