If multiple gates are arranged with short distances between each other, these will mutually
interfere with each other. The Readers for the respective gates must then be synchronized.
To achieve three-dimensional capture of the tag in the capture area drawn above, the following
conditions must be met:
-
The gate distance GD depends on the antenna configuration (see Table 2: Design notes).
-
The tags should be at least ISO card size (46 mm x 75 mm).
-
The activation field strength of the tags should be less than or equal to 80 mA/m.
-
The distance from tag to tag should be greater than 10 cm. If the tag to tag distance is reduced,
the gate distance GD must be reduced correspondingly. This applies in particular to distances
under 5 cm.
-
The maximum number of tags (serial number or data) depends on the traverse speed with
which the tags are brought through the capture area of the gate (see Table 2: Design notes).
The number of tags may be increased in the gate distance GD is correspondingly reduced and
the maximum speed adjusted accordingly.
-
The antenna should be at least 50 cm from metal parts.
-
There should be no interference of the Reader from other electrical devices in the environment.
The Noise Level difference should be less than 30 mV.
-
The ID ISC.LR2000 Reader should be set to an RF power of 8 watts.
-
When using ISO 15693 transponders, the Readers should be set as described
in
4.2.7
Reader
Configuration
with Power Splitter or
4.3.8
Reader Configuration
with Multiplexer.
-
If multiple gates are operated at the same time at a distance of less than 8 m, the Readers
must by synchronized. See Application Note
Synchronizing RFID LongRange Readers using
the digital in-/outputs
(N11200-1e-ID-B.pdf).
