The rise of the mobile phone and its role in the revolution of personal communication
The rise of the mobile phone and its role in the revolution of personal communication. In 1945, researchers in the US came up with a way of allowing a weaker telephony signal which could be re-used without interference. This enabled a smaller battery to be held in a hand-held or cellular phone. However it needed the invention of a new technology - microprocessors - before the first cellphone was built.
