Wireless \Wire"less\, a.
   Having no wire; specif. (Elec.), designating, or pertaining
   to, a method of telegraphy, telephony, or other information
   transmisssion, in which the messages, data, etc., are
   transmitted through space by electric waves; as, a wireless
   message; a wireless network; a wireless keyboard.
   [Webster 1913 Suppl. +PJC]

   Wireless telegraphy or Wireless 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.
      [Webster 1913 Suppl.]

The Free On-line Dictionary of Computing (30 December 2018):

wireless

    A term describing a computer network where
   there is no physical connection (either copper cable or fibre
   optics) between sender and receiver, but instead they are
   connected by radio.

   Applications for wireless networks include multi-party
   teleconferencing, distributed work sessions, personal
   digital assistants, and electronic newspapers.  They include
   the transmission of voice, video, images, and data, each
   traffic type with possibly differing bandwidth and
   quality-of-service requirements.  The wireless network
   components of a complete source-destination path requires
   consideration of mobility, hand-off, and varying
   transmission and bandwidth conditions.  The wired/wireless
   network combination provides a severe bandwidth mismatch, as
   well as vastly different error conditions.  The processing
   capability of fixed vs. mobile terminals may be expected to
   differ significantly.  This then leads to such issues to be
   addressed in this environment as admission control,
   capacity assignment and hand-off control in the wireless
   domain, flow and error control over the complete end-to-end
   path, dynamic bandwidth control to accommodate bandwidth
   mismatch and/or varying processing capability.
