EM Exposure Monitoring

 

There is an increasing number of devices and networks that are based on wireless electromagnetic fields transmissions: 

• Health hazard TBD to some extent → Downward revision of emission limits
• Social unrest due to the lack of reliable and rigorous information

Analysis under two points of view:

• Consequences: analysis of the potential health effects (Operational restrictions / Regulatory framework)
• Causes: EMF measuring and monitoring

Assets and expertise: 

• Setting and configuring an instrumentation system for measuring local:
  • Environmental EM exposure: Worst case scenario
  • Accurate instanteneous EM exposure sort per radiocommunication service
  • Personal EM exposure
• Characterizing the changing behaviour of materials under EM exposure:
  • Organic tissues
  • Fabrics
• EM exposure continuous monitoring in an area:
  • Desing of monitoring networks:
    • Topology (Sensor nodes; Processing hubs; Cloud DDBB)
    • Sampling and data conditioning.
  • Measured data processing:
    • Statistical characterization of EM exposure levels
    • EM exposure maps
• Theoretical-empirical models por EM exposure prediction in the far field region:
  • SOCER: Software for the estimation of radioelectric emissions.
  • Theoretical propagation models complemented by statistics based on on-the-field measurements.
• Channel models for wireless communications of body area networks:
  • In-body & on-body sensors
  • NFC, Bluetooth...
