Abstract
A method of communication between an RFID reader (1) and a plurality of transponders (2a, 2b) via a radio channel (20) is disclosed. The method comprises the steps of measuring a noise level (SN) of the radio channel (20), selecting an error correction algorithm (ECA1, ECA2, . . . ECAx) depending on the result of the noise level (SN) measurement, and setting both the RFID reader (1) and the transponders (2a, 2b) to the selected error correction algorithm. Furthermore, an RFID reader (1) is disclosed, which is adapted to perform the method according to the invention.
