The research group focuses on the analysis and development of advanced Information and Communication Technologies (ICT), with particular emphasis on networking, wireless and optical systems, sensor networks, Internet of Things (IoT) technologies, and mobile and satellite communications. The group’s expertise encompasses information and signal processing in telecommunications, energy-efficient ICT systems and networks, machine learning applications, network and system security, as well as the development of communication software and network-based services. Research activities cover energy-efficient ICT infrastructures, secure communication systems, positioning and synchronization in communication networks, wireless sensor and IoT networks, data transmission and processing systems, and emerging paradigms such as cognitive networking, software-defined networking (SDN), network function virtualization (NFV), cloud computing for data centres, and virtual reality systems.
