Jan 1, 2025
This computational study modeled electromagnetic exposure for military personnel near vehicular communication antennas across HF, VHF, and UHF scenarios. All simulated configurations reportedly met ICNIRP Basic Restrictions, though some exceeded ICNIRP Reference Levels in certain positioning and frequency…

This study modelled SAR in humans near fixed multi-antenna UHF RFID readers operating at 866 MHz, representing RTLS and PPE-monitoring use scenarios. The modelling suggests that at 5 cm distance, SAR may warrant consideration against international exposure limits aimed at preventing thermal effects when effective…

This study simulated SAR from handheld UHF RFID readers (“RFID guns”) in adult male and female models across seven close-proximity scenarios involving an operator, scanned person, or bystander. SAR was reported to comply with general public limits at emissions up to 1 W, but higher-power devices (>2 W, and especially…

This geo-epidemiological population-based study in Limousin (France) assessed modeled residential UHF-EMF exposure from GSM antennas and ALS incidence from 2000–2012. The authors report a statistically significant exposure–response trend and higher ALS risk in the highest exposure category versus non-exposure in both…

This animal study assessed redox-state changes in rat brain cells after long-term low-intensity ionizing radiation exposure or fractionated non-thermal UHF electromagnetic radiation. Both exposures were associated with decreased ubisemiquinone and increased NO-FeS-protein complexes, alongside increased mitochondrial…

Jan 1, 2015
This in vitro study used voltage clamp recordings of single OmpF porin channels in an artificial bilayer to test effects of UHF EMF (910–990 MHz). The authors report frequency-dependent changes in channel gating, with increased gating frequency and voltage sensitivity and a maximum effect at 930 MHz. Conductance was…

Jan 1, 2014
This animal study exposed rats of different early-life ages to 950 MHz UHF electromagnetic radiation for 30 minutes per day (SAR 1.0–1.3 W/kg) across gestation and/or early postnatal periods. The authors report no evidence of oxidative stress by TBARS or protein carbonyls, but report changes in fatty acid…

Jan 1, 2011
This engineering paper describes a system implementation for interoperation between a 915 MHz UHF RFID reader and a TCP/IP gateway device. The architecture uses wired communication between the TCP/IP device and RFID reader, and wireless ZigBee (IEEE 802.15.4) links to an end-device/coordinator. Web-based tests are…
