4.1 Fundamentals of application planning
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

Width of the transmission window

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