Interference and Collocation Interference Demonstration
Radio interference occurs when two or more RF systems affect one another’s smooth operation. This normally occurs when two or more RF systems are operating physically close to one another and they are operating in such a way that one of the transmitters negatively impacts one or more receivers. Through this demonstration video you will learn how to analyze and mitigate collocation interference on a ship and also how to analyze and find solutions for interferences between ground radio stations.
