<p>The unit has an antenna for receiving a clock signal with a clock frequency transmitted from a reader. Frequency sensors generate sensor frequencies for pulsing transmission of data. A frequency comparator determines frequency difference between the clock frequency and the sensor frequencies. A limiting device limits a data block parameter of the data to another data block parameter depending on the frequency difference. Transmission time points (121, 122) of a bit of the former parameter are compared with transmission time points (123, 124) estimated by the reader. Independent claims are also included for the following: (1) a system for data transmission including a transponder unit (2) a method for transmitting data from a transponder unit to a reader.</p> |
