Dwell time of the transponder
The dwell time is the time in which the transponder remains within the transmission window
of a reader. The reader can exchange data with the transponder during this time.
The dwell time is calculated thus:
t
V
:
Dwell time of the transponder
L:
Length of the transmission window
v
Tag
:
Speed of the transponder (tag) in dynamic mode
0,8:
Constant factor used to compensate for temperature impacts and production toler-
ances
The dwell time can be of any duration in static mode. The dwell time must be sufficiently long
to allow communication with the transponder.
The dwell time is defined by the system environment in dynamic mode. The volume of data
to be transferred must be matched to the dwell time or vice versa. In general:
t
V:
:
Dwell time of the data memory within the field of the reader
t
K
:
Communication time between transponder and communication module
