Long-range radio refers to communication systems that can transmit signals over vast distances, often exceeding hundreds of miles. This technology utilizes low-frequency radio waves, which can travel long distances by bouncing off the ionosphere, a layer of the Earth's atmosphere. Long-range radio is commonly used in maritime, aviation, and emergency services for reliable communication. One popular application of long-range radio is in amateur radio, where enthusiasts use various frequencies to connect with others around the world. Additionally, long-range radio plays a crucial role in military operations, enabling secure communication in remote areas where traditional networks may not be available.
