Machine to Machine Communications (M2M)

WELCOME to the institutional website of the Machine-to-Machine (M2M) Communications Department at CTTC. You can also have access to the frequently updated website of the department at

The M2M Communications Department conducts research, development, and innovation actions in the area of ICT technologies for the hyperconnected vision of a world where everything will be inter-connected and Internet-connected.

This hyper-connectivity will make it possible to realize the holistic concept of the Internet of Things (IoT) and will be a key and necessary enabler for emerging vertical applications in different domains, such as Industry 4.0 or Connected and Automated Mobility (CAM), among others.

The activities of the M2M communications department aim at TRL levels between 1 and 5.

The main OBJECTIVES of the M2M department are to:

  1. Conduct research and development activities in the area of M2M Communications for the sake of generating new knowledge in this domain.
  2. Disseminate R&D activities and achieved outcomes within both the scientific and industry communities.
  3. Develop proof of concept demonstrators for novel technologies.

The main TECHNOLOGIES used by the M2M department are:

  • 5G Technologies, with main focus on V2X (vehicular-to-anything communications).
  • LPWAN – Low Power Wide Area Networks: LoRa, Sigfox, LTE-M, NB-IoT.
  • Short-range Communication Technologies: WiFi and Bluetooth.

The main RESEARCH LINES for the M2M department are:

  1. Design of random access protocols for massive connectivity.
  2. Analysis, design, simulation and implementation of energy efficient communication technologies for wireless M2M networks.
  3. Data-oriented networking and resource allocation for M2M communications.
  4. Probabilistic data structures for big data handling.
  5. Leverage Multi-Access Edge Computing (MEC) for connected objects.
  6. Predictable performance for M2M applications and services using Software Defined Networking and Network Function Virtualization (SDN/NFV) through Network Slicing.
  7. Cooperative-Intelligent Transportation Systems based on Vehicle-to-Everything (V2X) networks.
  8. Cyber-Physical Systems (CPS) in the context of Industry 4.0.
  9. Design, fabrication, and measurement of end-to-end IoT prototypes.
