Radio Frequency CompatibilityAbility of antenna-connected RF receiver and transmitter subsystems operating within a system to function properly without performance degradation caused by antenna-to-antenna coupling.
Radio Frequency InterferenceAlso known as Electromagnetic Interference. A disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
RFIAlso known as Electromagnetic Interference. A disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
