A invenção do rádio (Guglielmo Marconi)

A invenção do rádio estava na casa de Guglielmo Marconi, com a idéia de transmitir do ar usando ondas de rádio enquanto continuava sua pesquisa. Em 1902, o inventor italiano, que continuou a trabalhar nesta direção, descobriu uma maneira de enviar mensagens de um lugar para outro sem fios ou cabos. Desta forma, o inventor, que iniciou formalmente o uso do rádio, alcançou um sério sucesso comercial.

 

Em 1894 Marconi, o inventor do radar foi capaz de usar o gerador de faísca elétrica, que foi feito por hertz, e um receptor de onda que Branly inventou, para tocar uma campainha a 9 metros de distância de onde estava localizado, e todas as ondas de rádio que colocou as fundações de um GRE no desenvolvimento do mundo. Durante este período, muitas pessoas disseram que o rádio foi descoberto antes de Marconi, mas Marconi foi aceito e patenteado apenas pelo sucesso comercial.

 

Popov, Lodge, e Marconi estavam tentando desenvolver um veículo usado para detectar ondas de rádio chamado o tubo de farelo, que Edward Branly encontrado. A partir de 1890, estes esforços de desenvolvimento foram encerrados em 1895 com o desenvolvimento de Marconi e Popov desconhecem uns dos outros. Pela primeira vez em 1896, o nome "Heinrich Hertz" de Popov foi compreendido usando o alfabeto Morse. Nos anos seguintes, Lee de Forest e Edwin Howard Armstrong fizeram grandes inovações nos Estados Unidos usando circuitos de tecnologia de rádio.
