Electromagnetic interference

Electromagnetic interference is the unwanted influence of technical sources in the surrounding area on radio or electronic signals. It can disrupt the signal transmission of an RFID system and cause read errors, unstable detection, or a reduced read range. Common causes include motors, converters, welding equipment, cables, or other transmitters. These influences must be taken into account when planning the RFID antenna, installation location, and transmit power so that the system operates reliably under real conditions. To identify potential problems and sources of interference, we carry out technical pre-qualifications in the real environment in which identification will later take place. In this process, RFID hardware is set up temporarily and tested under actual conditions. This allows critical influences to be identified and reduced before final implementation.
