R&I group

Mobile Wireless Internet

The Mobile Wireless Internet (MWI) research group focuses on two main domains: i) 6G architecture, and ii) Intelligent transportation Systems (ITS). Regarding 6G architecture, MWI develops cutting-edge research in the areas of: i) NTN, ii) O-RAN, and iii) APIs to support vertical services. In the ITS domain, MWI focuses on: i) development of cooperative CCAM strategies leveraging ETSI-G5 protocol stacks, and ii) development of Vehicular Digital Twins that assist road operators in applying smart traffic management strategies.

Research lines

The Software Defined Wireless Networks (SDWN) research line works on 6G architectural concepts, including NTN, O-RAN and Network APIs. In the NTN domain, the group has developed Store & Forward mechanisms for NB-IoT networks with discontinuous feeder links. In the O-RAN domain, the group has focused on developing AI/ML mechanisms enabling MNOs to control the QoS and energy consumption trade-offs. In the domain of Network APIs, the group has developed a rate recommendation API for XR services and a predictive QoS API for teleoperated driving services.
The Vehicular Communications (V2X) is working on the development of cooperative applications based on the ETSI-G5 protocol stack and on the development of vehicular digital twins (VDTs). Regarding ETSI-G5 protocols, the group has open-sourced FlexStack, a Python-based stack developed in-house over the last years. Regarding VDTs, the group has developed a recommendation engine, which assists road operators in making traffic management decisions to mitigate traffic jams due to accidents on the road, or to reduce the impact of a pollution event.
