Towards unconstrained mobility [intelligent transportation systems]

In this paper we give an overview of trends, options and new concepts for mobile Internet and intelligent transportation systems (ITS) services in Europe. We review technologies and standards and focus on new initiatives which allow for mobile, personalised and location-sensitive Internet and ITS services with a high degree of flexibility and user-friendliness. We give some examples of European research projects on the integration of cellular mobile radio (GSM, GPRS, UMTS) with broadcasting systems (DAB, DVB-T), satellite navigation systems (GPS, Galileo) and short range communications techniques (IrDA, Bluetooth).
