Heinlein described mobile pocket phones in 1948, 1953, and 1962. (although they were probably analog) http://www.technovelgy.com/ct/content.asp?Bnum=595 http:/

  Amazing, but a bit different prediction, Heilein (from the link provided) described mobile phones at a time where there was walky-talkies (invented in 1937). The difference between walky-talkies and mobile phones is in the lack of phone switches and base stations, not so much in the terminal. Brunner described phones (not necessarily mobile) that had a camera and a screen and that were used to access encyclopedias. There was at that time ATT's picturephone, but it was point to point connections through the switched network. Given it used a Vidicon tube for the camera an a cathodic tube for the screen, it must have been quite large. And it was not used to find information on online encyclopedias. Hey it was published even before Arpanet was launched!

  You just started me foraging in Wikipedia :-) There was a public wireless phone system in trains in Germany that was launched in 1924. And behind the iron curtain, there were people that did develop pocket phones (one weighted only 70g). Thanks for starting this discussion! https://en.wikipedia.org/wiki/History_of_mobile_phones https://en.wikipedia.org/wiki/History_of_mobile_phones
