Terrestrial networks only cover 10% of The Earth’s surface. This provides a high potential to satellite technology. Monitoring the status of a large number of sensors installed in remote locations with satellite links based on M2M technology is the most suitable solution applications such as vehicle telemetry, fleet management, marine vessel tracking, energy management, container tracking or remote field service applications, among many others.
Therefore, M2M-enabled satellite communications constitute a very hot area of research. The M2M Department of CTTC focuses its activities on two main areas:
- Design of low-complexity energy-efficient reconfigurable encoding and decoding schemes for M2M communications.
- Design of a new generation of access protocols to support the second generation of Digital Video Transmissions (DVB) based on Return Common Satellite (RCS) channel. The DVB-RCS2 Standard is suitable for M2M networks based on sensors since this standard supports traffic data with burst statistics. However, it is still necessary to reduce its complexity and increase the energy-efficiency.
- Reliability; trading the energy-efficiency and low-complexity of communication through satellite with the fault-tolerance.
