Motorola Car Telephone Model TLD-1100, 1964

AEG 4015C telephone for the German B Network ca. 1979

A car phone is a mobile phone device specifically designed for and fitted into an automobile. This service originated with the Bell System, and was first used in St. Louis on June 17, 1946. The original equipment weighed 80 pounds (36 kg), and there were initially only 3 channels for all the users in the metropolitan area. Later, more licenses were added, bringing the total to 32 channels across 3 bands (See IMTS frequencies). This service was used at least into the 1980s in large portions of North America. On October 2, 1946, Motorola communications equipment carried the first calls on Illinois Bell Telephone Company's new car radiotelephone service in Chicago. Due to the small number of radio frequencies available, the service quickly reached capacity.
