The Federal Communications Commission this week set the rules for devices intended for operation in FirstNet, the United States’ first wireless broadband network dedicated to first responders and emergency services. The network will reportedly be funded at $7 billion through TV spectrum auction proceeds, with another $135 million allotted for a state and local implementation … [Read more...]
IEC 61000-4-6:2013: EMC – Part 4-6: Testing and Measurement Techniques – Immunity to Conducted Disturbances, Induced by Radio-Frequency Fields
From the International Electrotechnical Commission webstore: "IEC 61000-4-6:2013 relates to the conducted immunity requirements of electrical and electronic equipment to electromagnetic disturbances coming from intended radio-frequency (RF) transmitters in the frequency range 150 kHz up to 80 MHz. Equipment not having at least one conducting wire and/or cable (such as mains … [Read more...]
Dolphins Inspire Radar System to Detect Hidden Electronics
Dolphins have inspired British researchers to create a new type of radar device that can detect hidden surveillance equipment and explosives and help locate buried avalanche or earthquake victims. According to New Scientist, the idea came to Timothy Leighton of the University of Southhampton’s Institute of Sound and Vibration Research while he was watching a nature show. After … [Read more...]
New Interference-Simulation Technology for Millimeter-Wave Radar

Webinar Questions & Answers
Editor’s note: This question was asked in response to Interference Technology’s recent webinar by Keith Armstrong. To view the webinar, click here. Q1. What did it take to fix the supercomputer immunity? A1. Can’t remember now, long time ago (22 years or so). Did I say immunity? I think it was actually emissions. But I do remember that it wasn’t very difficult, really, just … [Read more...]
Active EMI/EMC Filters Provide High Levels of Attenuation in Small Package
Electronics distributor Digi-Key is now offering Vicor Corporation’s compact QPx series of active EMI/EMC filters. The new components provide high levels of attenuation in a fraction of the size of traditional solutions. The Picor QuietPower QPO output ripple attenuator uses proprietary active filtering to reduce power supply output ripple and noise (PARD) over 30 dB from 1 … [Read more...]
Inductive Charging to Increase EV Market Demand, Says Volvo Study
Volvo Car Group has completed a wireless charging system trial for electric vehicles, concluding that although the technology works and is considered safe, its lack of common standard means it is not yet ready for the consumer market. Inductive charging, which uses an electromagnetic field instead of a cable to transfer energy between two objects, is common in electrical home … [Read more...]
Cheney Disabled Cardiac Device Wireless Function to Prevent Terrorist Attack
In a recent interview with CBS' 60 Minutes, former Vice President Dick Cheney said he was so concerned that terrorists could use the electrical device that had been implanted near his heart to kill him that he had his doctor disable its wireless function. Cheney has a history of heart trouble, suffering the first of five heart attacks at the age of 37, reports the Associated … [Read more...]
