WebTwo terms commonly used to describe RF noise are Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). EMI is random, broadband noise whereas RFI is narrowband noise broadcast at specific frequencies. EMI is generated by non-broadcast electronic devices and electric motors. http://mwp.nuaa.edu.cn/_upload/article/files/90/61/7c515cc6418f8cb5f5fbc0543f4e/3defa65f-eec5-4a93-8118-916a8120548f.pdf
