Определение
РАДИОСВЯЗЬ
электросвязь, осуществляемая посредством радиоволн. Передача сообщений ведется при помощи радиопередатчика и передающей антенны, а прием - при помощи приемной антенны и радиоприемника. В радиопередатчике формируются радиосигналы - электрические колебания несущей частоты, промодулированные по амплитуде, частоте или фазе в соответствии с передаваемым сообщением (см. Модуляция колебаний). Радиосигналы излучаются (в виде электромагнитных волн) передающей антенной в окружающее пространство, достигают приемной антенны и поступают в радиоприемник, где они усиливаются и преобразуются в сигналы, адекватные передаваемому сообщению. Радиосвязь впервые продемонстрирована 7 мая 1895 А. С. Поповым. Линии радиосвязи используют для передачи телефонных (речевых) сообщений, телеграмм, факсимиле, цифровой информации, радиовещательных и телевизионных программ.

History of radio
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
