'Interference' in radio transmission specifically refers to unwanted signals that disrupt the desired communication. This occurs when additional signals, whether from other radio sources or noise, overlap with or detract from the intended transmission. Such interference can lead to distortion, reduced clarity, or even complete loss of the primary signal, making it difficult for the receiving device to accurately interpret the information being transmitted.

Understanding interference is crucial for ensuring effective communication within radio operations, as it highlights the need for techniques to minimize these disruptive influences. Methods may include frequency selection, signal filtering, and using modulations that can withstand external noise, all aimed at maintaining clear and reliable communication channels.
