ACG 150


As part of the ACG 150 strategic plan, the RTIN seeks to combine the in-house research and innovation (R&I) potential stemming from ACG’s faculty, schools, departments, institutes, centers, programs and labs with an external network of collaborators and innovation players (corporations, investors, start-up clusters and incubators, funding agencies, innovation and market fora and think-tanks, venture capital funds, standardization and regulatory authorities, legal counsels, sponsors and donors). The doors of RTIN are open to all ACG faculty, while it hosts a number of research fellows and members from ACG, as well as resident and visiting researchers that work on various research and innovation-oriented projects.

Virtually unlimited in theme and scope, the Network’s activities track the evolution of many science and technology (S&T) disciplines that shape our world. Some current areas that are addressed through the activities of current Deree and ALBA faculty include: information and communication technologies (next generation networks including the Internet-of-Things, data science, artificial intelligence, cyber security, etc.), optimization and operations research, economics and finance, marketing, business and management, biomedical science and e-health, psychology and cognitive science, visual arts, literature, philosophy, history and journalism.


To serve as a nexus for research, innovation and technology development and transfer, promoting the generation of intellectual property and its connection with potential investors, entrepreneurs and start-ups, in order to foster economic development in Greece and beyond.


To become a Greece-based hub of research and technology-oriented innovation of global appeal.


The Research, Technology & Innovation Network aims at impacting science, technology and business along the following key axes:

Contribute to the S&T knowledge base via top-tier publications and white / position papers
Participate in collaborative R&I via joint research and industrial projects
Foster industry-oriented innovation via patents, standards contributions and policy advising
Kick-off startup companies and promote other innovation-based entrepreneurship endeavors

The RTIN targets the generation of 100s of publications and patents, participation in 10s of projects and kicking off of several startup / collaborative industrial innovation activities in its first 5 years of operation.

With Greece’s gross domestic research expenditure at only 1.17%, we aim to help bring this figure closer to the EU average of 2.06% (and target of 3%) and to contribute to the generation of 10s of thousands of jobs and several billion Euros of annual turnover added to the Greek economy.

The RTIN’s planned involvement in the STR is primarily targeted at the demonstration of business innovation concepts and proposals related to its activities.

Fab Lab

The newly created Fab Lab at ACG’s Pierce High School offers a new technologies workshop in which students learn by experimenting, using digital fabrication machinery and designing tools to implement their original ideas. Equipped with 3D printers, a laser cutter, a 3D scanner, a vinyl cutter, a CNC machine, robotics kits and an electronics workbench, the Fab lab facilitates experimentation with creative electronics, such as sensors, microcontrollers, conductive ink, e-textiles, etc. The RTIN plans to participate in the lab’s activities to help foster the early exposure of high-school students to the world of research & innovation.

Research Projects & Industrial Collaborations

The RTIN participates in a number of collaborative research projects which are conducted jointly with external partners and funding.

EU Innovative Training Network project PAINLESS

PAINLESS (“Energy-autonomous portable access points for infrastructure-less networks”) is a €4M multi-partner European Training Network (ETN) project, within the framework of the H2020 Marie Skłodowska-Curie Innovative Training Networks (ITNs) of the Horizon 2020 Program of the European Commission. It was launched in 2018 with the visionary aim to establish a training and research platform to pioneer green, energy-autonomous portable network nodes that are self-subsistent and limitlessly scalable, to satisfy future demands with minimal infrastructure. PAINLESS forms part of the H2020-MSCA (Marie Skłodowska-Curie Actions) with a vision to produce the first generation of experts in a radically new wave of energy-autonomous networks that will revolutionize the wireless networking technology landscape and the plethora of associated vertical business sectors. The RTIN participates in the project under ALBA. Dr. Papadias is the project’s Research Coordinator and RTIN Researchers, Muhammad Haroon Tariq and Nithin Babu are PAINLESS Early Stage Researchers.


FIREMAN is an EU-CHIST-ERA project on the topic of Big data and process modeling for smart industry (BDSI) with a budget exceeding 1M€. It proposes an Internet of Things (IoT)-based industrial cyber-physical system (CPS) and works in three generic steps: 1) Large data acquisition/dissemination: a physical process is monitored by sensors that pre-process the (assumed large) collected data and send the processed information to an intelligent node (e.g., aggregator, central controller); 2) Big data fusion: The intelligent node uses artificial intelligence (e.g., machine learning, data clustering, pattern recognition, neural networks) to convert the received (“big”) data to useful information to guide short-term operational decisions related to the physical process; 3) Big data analytics: The physical process together with the acquisition and fusion steps can be virtualized, building then a cyber-physical process, whose dynamic performance can be analyzed and optimized through visualization (if human intervention is available) or artificial intelligence (if the decisions are automatic) or a combination thereof.
In doing so, FIREMAN uses the Internet of Things to create a new structure of awareness – a cybernetic one – upon physical processes. Industries of different kinds are expected to benefit from this revolution, leading to Factories of the Future within the context of the so-called “Industry 4.0”. Dr. Papadias is the project’s Technical Coordinator and Dr. Ioannis Christou is a Lead Technical Contributor.

EU Marie Skłodowska-Curie project ComRad

ComRad (“Combining MIMO Radar with MU-MIMO Communications: More than Coexistence”) is a H2020 Marie Skłodowska-Curie Action – Individual Fellowship (MSCA-IF) project awarded to Dr. Fan Liu of University College London (UCL), under the primary supervision of UCL Professor Dr. C. Masouros. The two-year project was launched in Nov. 2018, with the aim of developing novel signal processing techniques for transmitting and receiving beamforming, waveform design, signal classification/recognition and channel estimation in order to enable the exploitation of radar spectrum for communication applications with a particular focus on 1) coexisting communication and radar systems (C-ComRad), and 2) Dual-functional communication-radar systems (D-ComRad). The RTIN participates as a research partner, hosting the fellow’s visits in its SWIFT Lab. Dr. Papadias participates as an external participant and co-supervisor. For more info, see here.

Academy of Finland project ee-IoT

ee-IoT (“Energy Efficient IoT Deployment for Systems of the Future”) is a three-year research project funded by the Academy of Finland that started in Oct. 2018. Its main objective is to develop an energy efficient machine-type communication (MTC) deployment for diverse Internet-of-Things (IoT) applications and their specific requirements. To achieve this, it studies the communication deployment as a transparent part of a Cyber-Physical System. In other words, the path from the sensed physical process to the end-application is a black-box that must achieve a pre-determined performance. Dr. Papadias participates in the project as “International Collaborator,” participating in student co-supervision and joint research activities in the area of energy-efficient wireless access techniques.

European Space Agency Project SatNEx V

SatNEx V (“Satellite Network of Experts V”), a continuation of SatNEx IV is an upcoming Network of Experts in the field of satellite communications that is funded by the European Space Agency (ESA)’s Advanced Research in Telecommunications Systems (ARTES) program. The project is coordinated by the Centre Tecnològic de les Telecomunicacions de Catalunya (CTTC) Research Center in Spain (Prof. A. I. Pérez-Neira) and its objectives are: The early identification, exploration and scientific assessment of promising new R&D avenues for satellite telecom networks for possible injection in ESA’s R&D programs; the detection and preliminary assessment of promising terrestrial telecommunication technology spinning into space telecom applications; and the enhanced cooperation between the European / Canadian industry and research institutions on telecom satellite applied research subjects of common interest. RTIN represents ACG in the consortium and Dr. Papadias participates as an Expert.

Collaboration with Nokia Bell Labs US on 60 GHz Wireless Propagation Measurements

In this collaboration with Nokia Bell Labs US, a team of researchers from RTIN’s Smart Wireless Future Technologies (SWIFT) Lab performed a measurement campaign of wireless channels on ACG’s main campus in Aghia Paraskevi. The project took place from March 2021 to Sept. 2021, during which time the ACG team performed a number of measurements of 60 GHz wireless channels, under the guidance of the Nokia Bell Labs team in New Jersey. The purpose of this measurement campaign was to characterize next-generation fixed broadband wireless channels in terms of parameters such as path loss, angular spread, gain degradation, and temporal variations in received power. The campaign included several parts of the campus such as the Communications building, the Deree courtyards, the Fine Arts building, the Admissions & Marketing offices & courtyard, the Faculty lounge, the Pierce Arts Studios, the open-air parking lot, etc. The campaign was successfully completed with a final report and a related publication is under preparation.

Collaboration with Spirit Aeronautical Systems (S.A.S) on UAV-based Wireless Access

This ongoing project is done collaboratively with Spirit Aeronautical Systems, a local technology company that specializes in unmanned systems technology ( The collaboration started in June 2021 and aims at the study and development of UAV-borne wireless access systems. The first phase of the project, which is underway, comprises a number of test flights in order to validate and possibly expand our models on the power consumption of the Unmanned Aerial Vehicle – UAV (drone) for a variety of flying conditions, heights and speed, as well as for the optimization of these parameters in terms of energy autonomy. The second phase, which is currently being planned, will target the integration of a wireless access point on a drone provided by S.A.S, in order to demonstrate its capabilities in real-world environments for UAV-assisted wireless connectivity. This work is also related to the theoretical studies our team has made in the context of the European (ITN) Project PAINLESS. A live demo of the developed prototype is planned for late spring of 2022.

Innovation activities

RTIN’s innovation activities are aimed in two directions: developing our own innovation capacity based on in-house expertise and generated intellectual property (IP), while acting as an innovation hub for external partners who seek innovation-oriented partnerships and support. In both cases, RTIN’s innovation is supported by the know-how of ACG’s staff and the available facilities and resources available at ACG’s schools and departments. Where possible and appropriate, RTIN seeks to connect its innovation activities to other centers and institutes within the ACG 150 initiative. Our innovation model explores both the generation of IP via a growing network of innovation facilitators and partners (platforms, clusters, incubators, venture capital firms, etc.) and the innovation funding instruments of the European Commission. The recently announced collaboration of ACG with the National Center for Scientific Research “Demokritos,” with the creation of the ACG Innovation Hub @ Demokritos, which will run under the direction of RTIN,  is a prime example of our involvement with the local research & innovation ecosystem,  ALBA’s recognized prowess in the area of entrepreneurship, as well as its privileged connections to the business world of Greece (such as via the ALBA Hub for Entrepreneurship and Development [AHEAD]), act as additional catalysts of innovation.

RTIN also relies on a number of specific innovation and competitiveness-directed partnerships and initiatives, that include the Innovation Accelerator, the Global Federation of Competitiveness Councils (GFCC), the Hellenic Innovation Network, and the Hellenic Initiative (THI) among others.


RTIN’s research work results regularly in scientific articles and books. Here is an indicative list of recent publications from the SWIFT Lab.
