Exposure Variability Between 1‐ or 6‐Minute and 30‐Minute Averaging Time Lengths in Radiofrequency‐Electromagnetic Field Exposure Monitoring

Bioelectromagnetics, Volume 46, Issue 8, December 2025.
ABSTRACT Different averaging time lengths (ATLs) are widely used in radiofrequency‐electromagnetic field (RF‐EMF) exposure monitoring. This study evaluated variability in RF‐EMF exposure associated with the ATLs of 1‐ and 6‐min normalised to 30‐min data. For 15 frequency bands of interest, RF‐EMF exposures were collected in contiguous 1‐min blocks over

Simulation and Analysis of Mobile Access (SAMA): Cellular Radio Access Network Simulator and Performance Evaluator Applied to 5G

IET Communications, Volume 19, Issue 1, January/December 2025.
This paper presents SAMA, a simulator for 5G Radio Access Networks (RAN), designed to evaluate the performance of different network configurations. The diagram illustrates the simulator's workflow: from inputs such as base station (BS) and user equipment (UE) arrangements, SAMA simulates resource allocation and scheduling, considering interference.
