In 1880, and his assistant created a very early precursor to fiber-optic communications, the, at Bell's newly established in. Bell considered it his most important invention. The device allowed for the of sound on a beam of light. On June 3, 1880, Bell conducted the world's first wireless transmission between two buildings, some 213 meters apart. Due to its use of an atmospher.
