Immediately after the invention of Volta battery, S.T. von Soemmerring observed that electric current through an arid solution caused bubbles to appear. He invented a telegraph system using this principle in 1809, which used 26 parallel wires to transmit letters of the alphabet a distance of up to two miles. In this article, we survey an early history of wired and wireless communication technologies, and state a perspective of mobile communication technology in the future.
