Overview
The transponder and reader complete with their antennas are inductive devices. Any type of
metal in the vicinity of these devices affects their functionality. Some points need to be
considered during planning and installation if the values described in the "Field data
(Page 48)" section are to retain their validity:
● Minimum spacing between two readers or their antennas
● Minimum distance between two adjacent data memories
● Metal-free area for flush-mounting of readers or their antennas and transponders in metal
● Mounting of multiple readers or their antennas on metal frames or racks
The following sections describe the impact on the operation of the RFID system when
mounted in the vicinity of metal.

Reduction of interference due to metal

Description
Problem:
A metal rack is located above the
transmission window of the reader.
This affects the entire field. In par-
ticular, the transmission window
between reader and transponder is
reduced.
Remedy:
The transmission window is no
longer affected if the transponder is
mounted differently.
