View Original AbstractWireless signals interfered with critical medical equipment at 50 centimeters, demonstrating measurable EMF effects on sensitive electronics.
Plain English Summary
Researchers tested whether modern wireless technologies (GPRS, UMTS/3G, and WiFi) interfere with critical medical equipment in hospitals. They found that GPRS signals caused an older infusion pump to stop working at 50 centimeters distance and interfered with 10 device displays, while UMTS and WiFi caused minimal problems. The study suggests these wireless technologies can be used safely in hospitals with proper distance precautions.
Why This Matters
This study reveals a concerning reality about electromagnetic interference that extends well beyond hospitals. While the researchers focused on medical device compatibility, their findings demonstrate that wireless signals can disrupt sensitive electronic equipment at distances we encounter daily. The fact that GPRS signals interfered with medical devices at 50 centimeters raises questions about similar interference with other electronic systems we rely on, from pacemakers to home medical equipment. What this means for you is that EMF emissions aren't just a theoretical health concern - they create measurable, documented interference with critical technology. The study's recommendation for one-meter separation distances provides a practical guideline, but it also confirms that these signals have real-world effects on electronic systems designed to meet strict safety standards.
Exposure Information
Specific exposure levels were not quantified in this study.
Study Details
In this study, we sought to determine if GPRS, UMTS (Wideband Code Division Multiple Access-Frequency Division Duplex [WCDMA FDD]), and WLAN (IEEE 802.11b) transmitted signals interfere with life-supporting equipment in the intensive care and operating room environment.
According to United States standard, ANSI C63.18-1997, laboratory tests were performed on 76 medical...
UMTS and WLAN signals caused little interference. Devices using these technologies can be used safel...
Terminals/cellular phones using these technologies should be allowed without restriction in public areas because the risk of interference is minimal.
