Open-source experimental B3G networks based on software-radio technology

We describe the overall architecture of an experimental software radio system providing direct interconnection with an IPv6 backbone network developped in the context of several publicly-funded research projects. RF and acquisition equipment ranges from high and low-power base stations (Radio Gateways) to reconfigurable terminals and can be made available to the research community for experimentation with real-time radio resources. Software can be configured for both real time deployment scenarios and radio network simulation on networked PCs. We describe issues related to interconnecting a third-generation cellular radio air-interface with an IPv6 backbone and its consequences on wireless networking architecture.
