Radio is the means of communication and signaling using radio waves. Radio waves are extremely long waves of electromagnetic frequency between thirty to two hundred gigahertz. These waves have the highest frequency that can be transmitted without causing interference. Advantages of using radio waves include availability, portability, and flexibility. Most use radio signals for communication in the form of radio announcements that are broadcast through various channels. Other uses include radio wave control machines, known as military use of radio waves, emergency rescue operations, weather forecasting, and entertainment. https://emisorasderadioonline.es/ frequencies are used in many parts of the world, especially in rural areas where mobile communication and entertainment are not available.
