EMFusion: Conditional Diffusion Framework for Trustworthy Frequency Selective EMF Forecasting in Wireless Networks
EMFusion introduces a novel conditional diffusion model for multivariate probabilistic forecasting of frequency-selective electromagnetic field (EMF) exposure in wireless networks. This framework integrates diverse contextual factors (time of day, season, holidays) and provides explicit uncertainty estimates. Utilizing a residual U-Net with cross-attention and imputation-based sampling, EMFusion ensures temporal coherence even with irregular measurements. It generates calibrated probabilistic prediction intervals, offering trustworthy decision-making unlike standard point forecasters. Experiments show EMFusion significantly outperforms baseline models, reducing CRPS by 23.85% and NRMSE by 13.93%, particularly with working hour conditions. It addresses critical gaps in existing EMF forecasting by capturing inter-operator and inter-frequency correlations, providing robust uncertainty quantification, and handling missing data.
Executive Impact Highlights
EMFusion delivers robust, probabilistic EMF forecasting, crucial for regulatory compliance and proactive network management. Its ability to quantify uncertainty explicitly and handle irregular data ensures trustworthy decision-making in dynamic wireless environments.

Overview of EMFusion
EMFusion is a conditional diffusion model for multivariate probabilistic EMF forecasting. It leverages a residual U-Net with cross-attention to integrate contextual factors like time of day, season, and holidays. This allows for the generation of diverse and realistic forecasts, including explicit uncertainty estimates via calibrated prediction intervals.
EMFusion Methodology
The framework models the joint distribution of multi-frequency EMF exposure trajectories, capturing complex inter-frequency dependencies. It uses an imputation-based sampling strategy, treating forecasting as a structural inpainting task, ensuring temporal coherence even with irregular measurements. The U-Net backbone processes noisy input with timestep embeddings and external context via cross-attention.
Enterprise Impact
EMFusion provides significant advancements for regulatory compliance, efficient network planning, and resource management. By delivering calibrated probabilistic forecasts and uncertainty quantification, it enables trustworthy decision-making for managing EMF exposure levels, assessing potential health impacts, and optimizing wireless network operations.

Real-World Application: Italian Wireless Network EMF Forecasting
Scenario: EMFusion was applied to frequency-selective EMF datasets from major Italian network operators (Iliad, TIM, VF, W3) and cellular technologies (2G, 3G, 4G, 5G).
Challenge: Existing methods failed to capture inter-operator/inter-frequency correlations and robustly quantify uncertainty amidst fluctuating traffic and irregular measurements.
Solution: EMFusion's conditional multivariate diffusion model integrated contextual factors (working hours, seasons), outperforming baselines significantly. It provided accurate, calibrated probabilistic forecasts for regulatory compliance and proactive network planning.
Outcome: Achieved 23.85% CRPS reduction and 13.93% NRMSE reduction. Enabled higher granularity for identifying dominant exposure sources and optimizing spectrum/power allocation policies.
