Penetration Loss Database
Material Dielectric & Transmission Database at 150 GHz
Empirical measurements and models of electromagnetic signal loss when traversing standard architectural materials (tinted glass, concrete, drywall).
Technical Explanation
A major challenge for high-frequency 6G is indoor penetration: energy-efficient thermal windows with metallic coatings attenuate Sub-THz waves by 30-50 dB, effectively blocking outdoor cellular signals from reaching indoor users. The 6G Penetration Loss Database compiles calibrated dielectric constants, refractive indices, and decibel-per-centimeter loss metrics across hundreds of modern construction materials, guiding the placement of indoor RIS and outdoor-to-indoor relays.
Key Functions
- Standardized database of transmission loss metrics across concrete, glass, drywall, and wood
- Measuring severe attenuation spikes caused by energy-efficient metallic window coatings
- Guiding the strategic deployment of outdoor-to-indoor optical and RIS repeaters
- Essential inputs for 3D ray-tracing channel simulators and network planning tools
- Informing building architects on RF-transparent construction materials for smart cities
