The introduction of new communication technologies may alter the ambient RF-EMF exposure, highlighting the need for in-depth temporal ambient RF-EMF characterisation. Thus, this study aims to characterise the temporal RF-EMF evolution in Switzerland using microenvironmental and long-term measurements during the rollout out of 5G. The data collection was done with ExpoM-RF4 from Fields at Work...

341. Is population density a valid predictor of personal far-field radiofrequency electromagnetic field exposure in human environments?

This study investigated how population density affects personal far-field radio-frequency electromagnetic field (RF-EMF, 88 MHz - 6 GHz) exposure in environments. We present results from 8 micro-environments in Gold Coast, Australia, that are part of a larger international measurement program. The RF-EMF exposures were measured using an ExpoM-RF4™ carried in a waist bag while undertaking a...

342. Low Cost SDRs for RF EMF Exposure Measurements

Applying Software Defined Radios (SDRs) for measuring exposure to Radio Frequency (RF) Electromagnetic Fields (EMF) requires calibrated sensors and antennas. A complicating factor is the influence of the person wearing the measurement device on the recorded exposure, as well as the sensor’s orientation relative to the EMF source. SDRs are not designed as power meters; they are typically used...

343. Spatio-temporal RF-EMF exposure assessment during six months in Belgium

The deployment of 5G has raised public concerns regarding potential health and environmental effects, prompting further research into RF-EMF exposure. This study presents the findings of a six-month measurement campaign conducted in Belgium using two RF-EMF sensors. One sensor was placed in a rural bedroom, while the other was installed in an office building in an industrial campus near a...

344. Average transmit power of a smartphone for auto-induced uplink RF-EMF exposure assessment during different usage scenarios in Belgium, Switzerland, and France

Bram Stroobandt

26/06/2025, 12:00

Differences in RF-EMF exposure from realistic smartphone usage scenarios becomes more important with the deployment of fifth-generation (5G) mobile networks. Previous studies only investigated legacy technologies or they were limited to measurement results in one country. This study assesses differences in average transmit power of a smartphone between voice calls, WhatsApp voice calls,...

345. Compact Exposimeter Device for the Characterization of Electromagnetic Fields from 78 MHz to 6 GHz with Several Narrow Bands (300 kHz)

Marco Rivera González

A new compact device, which allows measurements in multiple narrow bandwidths over the entire spectrum from 78 MHz to 6 GHz. This device has characteristics of a spectrum analyzer and integrates fractal antennas for its operation. The device has been calibrated and validated against a spectrum analyzer for far-field measurements. A strong correlation between the two devices with confidence...
