A communication gateway for infrastructure-independent 4G wireless access

Wireless communication infrastructure is characterized by an increasing multitude of heterogeneous systems. At the same time, service provider models are established and services designed to span physical networks irrespective of the access method used. To provide an infrastructure-independent access to services and applications for highly mobile users (e.g., in cars), we present a communication gateway architecture as an important component of fourth generation wireless communication systems. We especially emphasize the role of digital broadcast networks for future mobile networking.
