Modeling Radiofrequency Electromagnetic Field Wearable Distributed (Multi-Location) Measurements System for Evaluating Electromagnetic Hazards in the Work Environment.
This engineering study modeled and tested a distributed wearable RF EMF measurement approach intended to reduce body-proximity effects on personal exposure meter readings. Numerical simulations covered 24 far-field wireless exposure scenarios (100–3600 MHz), and physical tests with three probes were also performed. The authors report that averaging at least three simultaneous on-body measurements at relevant locations can substantially reduce discrepancy/uncertainty versus unperturbed field values, by about threefold.
Key points
- The work addresses measurement error introduced when wearable RF meters are worn close to the human body.
- Distributed multi-location measurements (up to seven locations) were modeled to better approximate unperturbed RF field conditions.
- Simulations represented far-field exposure scenarios typical of wireless communication systems, including different propagation directions and polarizations.
- Physical tests with three EMF probes were conducted to support the modeling approach.
- Averaging at least three simultaneous on-body measurements was reported to reduce uncertainty by roughly threefold.
- The study focuses on improving exposure assessment methods rather than evaluating health outcomes.
