How can interference in radio communication be reduced?

Utilizing frequency hopping techniques is an effective method to reduce interference in radio communication. Frequency hopping involves rapidly switching the transmission frequency among many different frequency channels during radio transmission. This technique makes it difficult for potential interferers to target the signal because they would need to anticipate the next frequency in the hopping sequence. Moreover, frequency hopping can enhance resilience against narrowband interference and jamming, as it distributes the signal over a wider spectrum, reducing the likelihood that any given interference will collide with the signal.

This method is particularly crucial in environments where multiple devices operate in close proximity or where the possibility of unintentional interference from other communications is high. By constantly changing frequencies, the communication system can maintain a clear connection despite the presence of noise or interference on some of the frequencies, effectively enhancing overall communication reliability.
