Debate Over Harmful Effects of Radio Waves Continues
Though the level of general concern about possible harmful effects from radio frequency radiation given off by mobile phones, wireless networks and smart meters has decreased in recent years, a small percentage of the population remains convinced that the electromagnetic radiation from wireless technology is dangerous. Patients with one condition, electromagnetic … [Read more...]
Upcoming Revision to the Medical Standard
We asserted last time that the existing amplifiers in the current test set up might be used to generate the higher stress levels if the test distance was reduced from 3 meters to 1 meter. As a reminder, we argued that testing at 1 meter means testing takes place in the near field as is the case for the threats faced by medical equipment (nearby cellphones etc.). Using the same … [Read more...]
Patent Awarded for New Method of Preventing RFID Tag Tampering
Canadian company Guard RFID Solutions has been granted a patent for a new method of determining and preventing RFID tag tampering for use in hospitals. Children staying overnight in a hospital pediatric ward are typically provided with an RFID tag that automatically triggers alarms and engages door locks, preventing the child from being forcefully removed from the area. While … [Read more...]
Wireless Medical Devices Face Security Concerns
A report issued recently by the U.S. Government Accountability Office (GAO) highlighted the growing use of wireless technology in complex medical devices and the concerns over adequate protection for the devices against security risks that could affect their safety and effectiveness. The report called on the Food and Drug Administration (FDA) to tighten security requirements of … [Read more...]
