Towards Environmental RF-EMF Assessment of mmWave High-Node Density Complex Heterogeneous Environments.
This paper presents an RF-EMF exposure assessment combining measurements and deterministic 3D ray-launching simulations in a large indoor public library with high node density. It considers mmWave 5G FR2 at 28 GHz and Wi-Fi 802.11ay at 60 GHz under realistic operation conditions with varying user distributions. The authors report compliance with international exposure limits, with levels far below those limits, and good agreement between simulations and measurements.
Key points
- Assesses RF-EMF exposure in a complex indoor environment with high-node density heterogeneous networks.
- Considers mmWave services including 5G FR2 at 28 GHz and IEEE 802.11ay at 60 GHz.
- Uses an enhanced in-house deterministic 3D ray-launching simulation tool for exposure estimation.
- Includes propagation and usage factors such as directive antennas, MIMO beamforming, body shielding, and obstacle material properties.
- Reports that exposure levels were far below current international regulatory limits in the studied scenario.
- Validates the simulation approach with an empirical measurement campaign showing good agreement.
