The history focuses on communication devices which connect wirelessly to the public switched telephone network. The transmission of speech by radio has a long and varied history going back to Reginald Fessenden's
invention and shore-to-ship demonstration of radio telephony. The first
mobile telephones were barely portable compared to today's compact
hand-held devices. Along with the process of developing more portable
technology, drastic changes have taken place in the networking of
wireless communication and the prevalence of its use.
