    • Radio Frequency Interference Measurements of Industrial Machinery

    Metadata Updated: September 30, 2025

    The 2.4 GHz ISM band is shared by Wi-Fi, Bluetooth, Wireless HART, ISA100.11a, and several other industrial wireless systems. Our dataset contains comprehensive electromagnetic interference (EMI) measurements from machinery taken in various industrial environments. The measurements were taken at two frequencies: 900 MHz, 2.4 GHz. This dataset may be useful for understanding EMI emitters in factories and can be instrumental in developing interference mitigation strategies, aiding in RF band selection and enterprise frequency planning, improving wireless technology, and informing communications standardization activities such as the IEEE 3388 industrial wireless performance evaluation standard.The interference measurements were taken in the following types of industrial environments:1) Infrared Curing Machine: Curing process using infrared radiation producing EMI across the 2.4 GHz band, 2) Crane with an Unshielded VFD: Overhead gantry crane operating at 900 MHz with an unshielded variable frequency drive (VFD) causing broadband interference, 3) Microwave Dryer: Two independent sets of measurements of a microwave oven baking machines used for a ceramic drying process. Multiple magnetrons are used with a power output of 1100 Watts each, 4) Unidentified Interference: General recording of the 2400 MHz band capturing both wireless network traffic and an unidentified broadband RFI emitter possibly caused by an unshielded VFD.NIST Disclaimer: Certain commercial equipment, instruments, or materials are identified in this publication in order to describe the experimental procedures and data adequately. Such identification is not intended to imply recommendation or endorsement by the National Institute of Standards and Technology, nor is it intended to imply that the materials or equipment identified are necessarily the best available for the purpose.
