At that time, the word'coherer', coined by Lodge, was used in the English-speaking world for Hertzian wave receivers or detectors.

More important for the future, the coherer could not detect AM radiotelephone signals, which began to be experimented with in the first years of the 20th century.

He later improved Branly's coherer by adding a " " trembler " " which dislodged clumped filings, thus restoring the device's sensitivity.
34.
In August 1898 he got, " Electric Telegraphy ", that made wireless signals using a Ruhmkorff coil for the transmitter and a Branly coherer for the detector.

Popov was the first to develop a practical communication system based on the coherer, and is usually considered by the Russians to have been the inventor of radio.
36.
In 1895-96 Popov and others utilized the coherer to show the existence of atmospheric electricity, using for the purpose a vertical wire attached to the coherer.

In 1899, Marconi announced his invention of the " iron-mercury-iron coherer with telephone detector " in a paper presented at Royal Society, London.

Therefore a "'decoherer "'mechanism was added, to tap the coherer, mechanically disturbing the particles to reset it to the high resistance state.
