Its development during the Second World War has been variously credited to Donald Hings , radio engineer Alfred J. Gross , Henryk Magnuski and engineering teams at Motorola .
Donald Lewes Hings, CM MBE (November 6, 1907 – February 25, 2004) was a British-Canadian inventor, born in Leicester, England.In 1937 [1] he created a portable radio signaling system for his employer CM&S, which he called a "packset", but which later became known as the "Walkie-Talkie".

A land mobile radio system (LMRS) is a person-to-person voice communication system consisting of two-way radio transceivers (an audio transmitter and receiver in one unit) which can be stationary (base station units), mobile (installed in vehicles), or portable (handheld transceivers e.g. "walkie-talkies").
Signals were obtained between the first and last-named points, a distance of approximately 8 miles (13 km). The receiving instrument used was a Morse inkwriter [109] of the Post Office pattern. [110] [111] In 1898, Marconi opened a radio factory in Hall Street, Chelmsford, England, employing around 50 people. In 1899, Marconi announced his ...
