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:

Description
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
environment.
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)
