Harmful Interference Mitigation in Sub-10 MHz Aeronautical Allocation Band

Wireless telecommunication needs spectrum frequency to convey information ubiquitously. Meanwhile, during a radio communication system deployment, harmful interference is a matter that should be avoided or at least to be mitigated because it causes degradation of the radio performance. Each particular spectrum frequency band has the threat of interference that comes from neighborhood service emitting radio waves based on improper manner. The interference sources could come from intentional activity or unintentional activity. In this paper, we will discuss an acute case of interference in sub-10 MHz of the Aeronautical Allocation Band that is pirated by traditional fishermen during their fishing activity in the Java sea in which an area of high density traditionally fishery activity. In this discussion, we propose a fundamental mitigation action to the Administration to avoid more destructive results, by giving a system called two ways radio simplex by using a 5.2 MHz/VHF-UHF crossband radio communication system. The Administration agrees to carry out POC (Prove of Concept) activity by this fiscal year.
