Shortwave broadcasting is a method of transmitting radio signals over long distances using shortwave radio frequencies, typically between 3 and 30 MHz. This type of broadcasting can reach listeners across continents, making it useful for international communication, news dissemination, and cultural exchange. Shortwave signals can bounce off the ionosphere, allowing them to travel beyond the horizon. Many countries use shortwave broadcasting to reach remote areas where other forms of communication may be limited. Organizations like the BBC World Service and Voice of America utilize shortwave to provide news and information to global audiences, especially in regions with restricted media access.
