The people felt the need of communication from vehicles and the effort of carrying radio equipment on moving platform like steam engine started as early as 1901. This long wave radio equipment was based on spark gap transmitter of Marconi Telegraph Company. Also during World War I, similar radio equipment was carried by Wagons with large number of storage batteries. In 1907, Alfred Grebe operated a crystal-based radio-telephone on car from long Island, N.Y. which was later on made using vacuum tubes in 1919, the high voltage required for vacuum tubes was generated using dynamotor. In 1908, Professor Albert Jahnke and The Oakland Transcontinental Aerial Telephone and Power Company claimed to have developed a wireless telephone, however, could not take efforts to produce it. In 1910, Frederick Baldwin and John McCurdy attempted for wireless radio communication between two planes, while in 1918, German Railroad System tested wireless telephony for their military trains. In 1921, base station in central Detroit was erected for the purpose of vehicular communication, however, as per the study by Robert Batts, power lines near it were compromising its operation and hence was moved to Belle Island in Detroit. Robert Batts modified radio equipment to use crystal control that was made to communicate with a vehicle fitted with wireless radio equipment having antenna running across the rooftop of the car. William P. Rutledge of Detroit police tried vehicular radio communication with the help of Robert Batts which was finally operational in 1928. Finally, in 1922, Gregorie Frost was successful in the integration of a radio equipment into a Ford model-T.
