To get a optimal performance the reader has to be configured and run in one of the
Automatic Modes (Buffered Read, Notification or Scan Mode).
If multiple gates are arranged with short distances between each other, these will mutually
interfere with each other which could cause a loss of read performance. This could be
reduced by installing a suitable shielding.

Table 2: Capture area, unintentional detection
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 4: 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 60 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 4: 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.
-
The minimum distance between the antennas of a gate and antennas of RFID work station or
terminals (transmitting frequency 13,56 MHz) should be:
