Paris Telecom Team Introduces REBT-DL Metric to Balance 5G Throughput and EMF Exposure

A theoretical study from Telecom Paris (Trinh, Wang, Wiart) builds stochastic-geometry models for downlink EMF exposure and energy efficiency in 5G multi-connectivity networks, using EN-DC as the reference use case (EN-DC is the 5G non-standalone mode combining a 4G LTE anchor with a 5G NR carrier). They introduce a new metric — Radiated Energy per Bit Transmitted in the Downlink (REBT-DL) — combining throughput and received power. Validated against real base-station data from Paris, the model shows that network configuration significantly affects both exposure and REBT-DL, and that a repulsion-aware point process (β-GPP) matches real deployments better than the standard Poisson model.

"This paper builds stochastic geometry frameworks for analyzing downlink electromagnetic field (EMF) exposure and efficiency in 5G multi-connectivity networks, using 5G E-UTRAN New Radio - Dual Connectivity (EN-DC) configuration as a representative use case."

"In addition to conventional metrics, we introduce the Radiated Energy per Bit Transmitted in the Downlink (REBT-DL), which accounts for throughput and received power."

"Results show that network configuration significantly affect exposure and REBTDL, highlighting the relevance of energy-aware deployment strategies and confirming the proposed approach as a comprehensive tool for sustainable network evaluation."
