Good point Barry. Reading your post reminded me of a school debate subject.
The actual wording escapes me. Technology lags behind theoretical science.
The concepts are about 10 years old by the time the products go into manufacture. Which more or less agrees with what has been written here.
WW11 Walkie-talkies. Huge beasts. Very thirsty on batteries. Its reasonable that they are the predecessor to cell phones. Particularly with the support of the repeater stations network.
However it still needed the high speed switching and logic systems of computers to operate. Yes, the earliest I know of such a system being developed was in the early 80's. Telstra had informed its technicians of the concept.
