"Introduction The word ""telematics"" is derived from TELEcommunication and inforMATICS (information technology). Telematics combines the power of information technology with advanced telecommunication technologies. Telematics technology is used across many fields. For example@ fixed telemetry devices such as water and gas consumption meters may process data and wirelessly transmit consumption information to a billing office@ while remote sensors (e.g.@ weather stations or traffic sensors) wirelessly transmit their information to a central control center. Automotive telematics systems connect vehicles to a communication infrastructure to provide services to users. This involves exchanging information among vehicle systems@ attached consumer electronic devices@ and telematics service centers. Vehicular communications started in 1921 with experimental radio telegraph installations. Since Motorola's invention of the first AM car radio in the 1930s@ people's desires to have information delivered to their cars and to have the ability to communicate with others outside their vehicles have increased steadily. In the late 1930s@ Motorola installed the first mobile communication radios in police cars@ using modified car broadcast radio designs. In 1942@ two-way capability began to be added to most police cars in most regions. In 1947@ the Citizen Band (CB) radio was created in the 27 MHz band. Since the early 1950s@ the CB radio has brought mobile wireless communication to the consumer@ allowing drivers to communicate with nearby vehicles. Telematics-like applications were developed as early as 1967@ when General Motors Research Laboratories presented its CB-radio-based Driver Aid Information Radio System (DAIR)@ and Ford presented its Ford Radio Alert system [1@ 2] "
