STRANGE HISTORY - FIRST CAR PHONES - 1924

Mobile phones, (aka cell phones and portable phones), began to flourish in the 1980's. But research and development into mobile phones dates back to the 1920's.

First car phone 1924 Built long before the transistor, imagine the size of the wooden box filled with vacuum tubes used to house the first mobile “phone” (like the one shown in this 1924 picture). Likewise, imagine the size of the batteries used to power it. Walking around with such a phone was not only impractical, it was impossible. So the first mobile communications devices were built into vehicles, primarily for military and public safety use. They also worked on radio frequencies (VHF) and were never part of any phone system.

The technology concepts for true cellular networks were not conceived until the 1940's. With transistors replacing vacuum tubes and better networks becoming available, cellular car phones were introduced – once again battery size keeping true mobile communicators out of the pockets of the glitterati.
