Reflection characteristics of the envi-
ronment
In a multiple-reflection environment (e.g., in rooms with
reflecting surfaces, machinery, or concrete walls), the read-
ing range can be significantly higher than in a low-reflection
Number of transponders in the antenna
field
The typical ranges always relate to a transponder installed
at the maximum possible distance from the antenna.
If there are several transponders located in the antenna
field, the distances to all other transponders must not ex-
ceed the maximum possible distance to be able to be de-
tected from the antenna field.
The width and height of the antenna field within which its
transponders can be arranged at a certain distance from
the antenna depend on the following:
• The radiated power,
• Only reading or reading and writing of the transponders
(writing requires more power, typically double the pow-
er)
• The aperture angle (horizontal)
• The aperture angle (vertical)
You will find detailed information about the reading range of the individual readers in the
"Technical specifications" in the sections for the various readers.
4.3.7 Static/dynamic mode
Reading or writing can be either static or dynamic.
● Reading/writing is counted as being static if the tag does not move in front of the antenna
and is read or written.
● Reading/writing is counted as being dynamic if the tag moves past the antenna during
reading/writing.
The following overview shows which environments are suitable for which read or write mode:
Static Recommended in normal UHF
Recommended in normal UHF
Dynamic Recommended under difficult
Not recommended in difficult
