The British phrase "wireless telegraphy" is one of those which, like aerodrome, was effortlessly transferrable between British and French forces during WWI, but which couldn't quite make it across the Atlantic to become fully accepted into American English. The French equivalent was télégraphie sans fil, which word-for-word translates as "telegraphy without wire." The British abbreviation, used by the military, was W/T. (When voice became transmittable over radio waves, the phrase used in the same era was "radio telephony," whose British abbreviation was R/T.)
