Bell's photophone Less than 10 years had passed since the appearance of a wired phone, when its author, Alexander Bell, developed the first device designed for wireless transmission of non-coded speech. This device was named Photophone. Structurally the Photophone consisted of two main components: a transmitter, which arranged modulating of the signal, and a receiver, in which the light signal, modulated in the transmitter, turned into modulated light vibrations. Structurally this was arranged by a flexible film, metalized on one side and polished. The light from a powerful source, situated at a specific angle to the transmitter, got on the microphone mirror and was modulated by the sound from the microphone. Modulated signal in the form of light was sent to a selenium photoelectric sensor. There the light was converted into voltage and was sent to the headphones as an audio signal. The radio range of this device depended on the conditions, time of the day, the source brightness, etc. However, experiments with the photophone can be considered one of the first successful experiments in wireless telephony and the first step to the mobile phone.

The Washington Post 2013-11-27The photophone (also known as a radiophone) is a telecommunications device which allowed for the transmission of both articulated sounds and normal human conversations on a beam of light. It was invented jointly by Alexander Graham Bell and his assistant Charles Sumner Tainter on February 19, 1880, at Bell's 1325 'L' Street laboratory in Washington, D.C. Both were later to become full associates in the Volta Laboratory Association, created and financed by Bell.
On April 1, 1880, Bell's assistant transmitted the world's first wireless telephone message to him from the roof of the Franklin School to the window of Bell's laboratory, some 213 metres (700 ft) away.
Bell believed the Photophone was his most important invention. Of the eighteen patents granted in Bell's name alone, and the twelve he shared with his collaborators, four were for the Photophone, which Bell referred to as his 'greatest achievement', writing that the Photophone was "the greatest invention [I have] ever made, greater than the telephone".
