The transponder can be used as soon as the intersection (SP) of the transponder enters the area
of the transmission window.
From the diagrams above, it can also be seen that operation is possible within the area between
S
a
and S
g
. The active operating area reduces as the distance increases, and shrinks to a single
point at distance S
g
. Only static mode should thus be used in the area between S
a
and S
g
.

Width of the transmission window
Determining the width of the transmission window
The following approximation formula can be used for practical applications:
: ɡ/
W:
Width of the transmission window
L:
Length of the transmission window
Tracking tolerance
The width of the transmission window (W) is particularly important for the mechanical tracking
tolerance. The formula for the dwell time is valid without restriction when W is observed.
