4.3.1

Overview

The MDS and SLG are inductive devices. Any type of metal, in particular iron and
ferromagnetic materials, in the vicinity of these devices will affect their operation. Some
points need to be considered during planning and installation if the field data described in the
preceding chapter are to retain their validity:
● The use of permissible mounting material
● The minimum distance between two antennas
● The minimum distance between two adjacent MDS
● The metal-free area for flush-mounting of SLGs in metal
● Mounting of multiple antennas on metal frames or racks
The following sections describe the impact on the functionality of the MOBY D identification
system when mounted in the vicinity of metal.
