IIT research units are its Labs which are structured in two research divisions and one services division.
- Intelligent Information Systems (IIS) Division, which includes the Computational Intelligence Lab (CIL) and the Software Engineering Lab (SKEL). It focuses on basic and applied research on Artificial Intelligence. Moving from text-centric AI to multimodal, web and social media content analysis, IIS has produced strong research outcomes in the field. Acknowledging early the importance of data analysis, IIS has also dedicated significant effort in the field of AI-based methods for big data management and processing.
- Telecommunications and Networks (T&N) Division, which includes the Media Networks Lab (MNL), the Telecommunications Network Lab (NeL), the Wireless Communications Lab (WiCom). The Division is a leader in the areas of 5G networks and produces significant results related to the relevant infrastructure, protocols used, and routing and packaging methodologies for optimising network performance and availability. The relevant expertise encompasses antenna technologies, Rx/Tx schemes and MIMO techniques, Radio Access Networks and multi-RAT connectivity, as well as technologies for network management, interoperability, softwarisation and virtualisation. Network performance, energy efficiency, QoS and QoE are also in focus, as are several networking technologies of IoT relevance.
- The Integrated Systems Lab (ISL), lies between the two divisions, being involved in research and product development in the areas of integrated information technologies and telecommunications, including GIS, location-based services, augmented reality and immersive VR/AR, indoor localization & navigation.
- Technological Services & Measurements Division, which includes the Net Media Lab – Mind & Brain R&D (NML- M&B) which develops various e-services and applications; the Networks – Internet Systematics Lab (ISLab) which studies internet security issues and has the responsibility of the core network infrastructure of NCSR, the Intelligent Software Solutions (ISS) which exploits the research outcomes of IIS, and the Mobile Communications Lab (MCL) which exploits the research outcomes of WiCom.
