(Auto) mobile communication in a heterogeneous and converged world

We discuss services and system architecture issues for future wireless communication in the vehicular environment. We consider the problem of wireless network heterogeneity that will be a consequence of emerging technologies such as wireless LANs, ad hoc networks, and broadcast systems, in addition to third-generation cellular standards like UMTS. In particular, a communication gateway architecture is proposed as an essential building block in future automobile systems. It enables services and applications within the car to transparently use different wireless communication systems. Our article gives a high-level view of the component architecture of the gateway and its adaptation layer to the wireless infrastructure
