Electrical Engineering, 1948
The first experiments in radio communication with automobiles appear to have been made in 1921 by the Detroit police department. In 1927 the experiments were renewed and by April of 1928 the Detroit police had a system in successful operation. Experiments having proved the utility of the 30–40-megacycle band for car-to-land transmission; power ...

Journal of the Institution of Electronic and Radio Engineers, 1987
After a brief historical survey of radio telephony developments, the paper first looks at the present position of mobile radio, particularly paging, cordless telephone and cellular services. Consideration is then given to the rapid technological developments in electronic components and circuits (particularly digital technology) and the miniaturization
