Automatic mobile telephone system

Mobile radio-telephone service has been available to the American public since its inauguration in St. Louis in 1946. While this service is quite extensively in use today by mobile subscribers, and to some extent in rural areas, the present system requires an operator to complete the connection between a mobile and land subscriber. This paper covers a development of equipment that will work satisfactorily into present dial telephone equipment. The system has been developed for the telephone section of the Rural Electrification Administration, and was the result of work done in the laboratory since 1946. The pilot system originally was installed in the North Florida telephone company´s property in Branford, Fla., and recently was transferred to the same company´s exchange in Live Oak, Fla.
