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 ...

In telecommunications and signal processing, information is transferred on a radio carrier wave by either modulating the amplitude or the frequency of a radio carrier wave. Radio waves have frequencies between 20 kHz and 300 GHz, corresponding to wavelengths of 15 km to 1 mm, and travel at the speed of light.

Commercial Radio Communications
1971Before discussing the problems of reliability experienced with individual component types, it is fundamental that the reader be given a wider insight into the generalities of this area of the electronics industry. What are the equipments used? How are they made, sold and serviced? What type of components are used?

Abstract : The results of an investigation of size reduction of the packet radio are present in this document. This results include: (1) The identification of the limitations and constraints to size reduction of the packet ratio; (2) Solutions and alternatives to these constraints; and (3) Design exercise for a small packet radio.
