9.3.2 Data rate and data coding
The RWD to HITAG µ transponder IC communication uses Pulse Interval Encoding. The
RWD creates pulses by switching the carrier off as described in
between the falling edges of the pulses determines either the value of the data bit ’0’, the
data bit ’1’, a code violation or a stop condition.
Assuming equal distributed data bits ’0’ and ’1’, the data rate is in the range of about
