Reading range

The reading range between the reader (antenna) and the transponder is affected by the
following factors:
The reading range depends on
Transmit power of the reader
Tag size and type
Absorption factor of the materials
Production quality of the tag
Reflection characteristics of the
environment
You will find detailed information about the reading range of the individual readers in Section
in the Appendix.

Description
The higher the transmit power of the reader, the larger the
reading range.
The larger the tag antenna, the larger the power input area
and therefore the larger the reading range.
The higher the absorption of the surrounding material, the
smaller the reading range.
The better the tag has been matched to the operating
frequencies during manufacturing, the greater the reading
range.
In a multiple-reflection environment (e.g., in rooms with
reflecting surfaces, machinery, or concrete walls), the
reading range can be significantly higher than in a low-
reflection environment.
