Radio-frequency Spectrum
In the maritime context, the radio-frequency spectrum refers to the part of the electromagnetic spectrum that is used for maritime communications and navigation. This spectrum ranges from 3 kHz to 300 GHz and is divided into specific frequency bands, each with its own designated purpose. In maritime operations, the radio-frequency spectrum is crucial for various applications such as ship-to-ship communication, ship-to-shore communication, navigation, radar operations, distress signals, and weather forecasting. The International Telecommunication Union (ITU) regulates the allocation of these frequency bands globally to ensure interference-free operation of maritime communication systems. The use of the radio-frequency spectrum in the maritime industry has greatly improved safety and efficiency. For instance, the Global Maritime Distress and Safety System (GMDSS), which operates within this spectrum, has revolutionized maritime safety by providing a fast and efficient way of calling for assistance at sea.
