Range
RSSI
Note
A
RSSI level (transponder) ≥ RSSI threshold
The transponder is within the recommended range of
the reading field.
B
RSSI threshold (parameterized)
The RSSI threshold can be defined individually (Index:
43h, Sub-Index: 03)
C
RSSI level (transponder) ≤ RSSI threshold
The transponder is within the maximum range of the
reading field.
D
–
The transponder is outside the reading field.
