The word "telematics" is derived from TELEcommunication andinforMATICS (information technology). Telematics combines the powerof information technology with advanced telecommunicationtechnologies.
Telematics technology is used across many fields. For example,fixed telemetry devices such as water and gas consumption metersmay process data and wirelessly transmit consumption information toa billing office, while remote sensors (e.g., weather stations ortraffic sensors) wirelessly transmit their information to a centralcontrol center.
Automotive telematics systems connect vehicles to acommunication infrastructure to provide services to users. Thisinvolves exchanging information among vehicle systems, attachedconsumer electronic devices, and telematics service centers.
Vehicular communications started in 1921 with experimental radiotelegraph installations. Since Motorola's invention of the first AMcar radio in the 1930s, people's desires to have informationdelivered to their cars and to have the ability to communicate withothers outside their vehicles have increased steadily. In the late1930s, Motorola installed the first mobile communication radios inpolice cars, using modified car broadcast radio designs. In 1942,two-way capability began to be added to most police cars in mostregions. In 1947, the Citizen Band (CB) radio was created in the 27MHz band. Since the early 1950s, the CB radio has brought mobilewireless communication to the consumer, allowing drivers tocommunicate with nearby vehicles. Telematics-like applications weredeveloped as early as 1967, when General Motors ResearchLaboratories presented its CB-radio-based Driver Aid InformationRadio System (DAIR), and Ford presented its Ford Radio Alert system[1, 2]
