What is radio frequency interference?
Radio frequency interference, RFI, is any undesirable electrical energy with content within the frequency range dedicated to radio frequency transmission. Conducted RFI is most often found in the low frequency range of several kHz to 30MHz. Radiated RFI is most often found in the frequency range from 30MHz to 10GHz.
Radio frequency (RF) is an electromagnetic wave that oscillates between the audio and infrared in the electromagnetic spectrum. Many natural RF signals exist in nature and indeed travel throughout the universe. But typical radio frequency interference (RFI) is defined as any unwanted signal received by a device that prevents clear or best wanted signal reception. This means that RFI can affect any signal receiving system such as televisions, computers, audio and security systems, and even automatic garage door openers. What are its causes? The FCC handles a wide range of signal interference complaints, RFI is but one of them. And RFI is hard to track down. This is because any device that generates or uses radio frequency as part of its operation can also cause radio frequency interference. The interference is broadcast through the air as radio waves or conducted through power lines. Naturally, communication equipment can cause interference, as can microwave ovens, computers, street lam
