Wireless \Wire"less\, a.
   Having no wire; specif. (Elec.), designating, or pertaining
   to, a method of telegraphy, telephony, etc., in which the
   messages, etc., are transmitted through space by electric
   waves; as, a wireless message.

   {Wireless} {telegraphy or telegraph} (Elec.), any system of
      telegraphy employing no connecting wire or wires between
      the transmitting and receiving stations.

   Note: Although more or less successful researchers were made
         on the subject by Joseph Henry, Hertz, Oliver Lodge,
         and others, the first commercially successful system
         was that of Guglielmo Marconi, patented in March, 1897.
         Marconi employed electric waves of high frequency set
         up by an induction coil in an oscillator, these waves
         being launched into space through a lofty antenna. The
         receiving apparatus consisted of another antenna in
         circuit with a coherer and small battery for operating
         through a relay the ordinary telegraphic receiver. This
         apparatus contains the essential features of all the
         systems now in use.

   {Wireless telephone}, an apparatus or contrivance for
      wireless telephony.

   {Wireless telephony}, telephony without wires, usually
      employing electric waves of high frequency emitted from an
      oscillator or generator, as in wireless telegraphy. A
      telephone transmitter causes fluctuations in these waves,
      it being the fluctuations only which affect the receiver.
