New Bill in Romania to Allow Telecom Operators to Pay Less if Radio Interference Occurs

 

Romania’s Ministry of Communications has proposed a bill that will allow telecommunication operators to pay less to use radio frequencies if the frequencies are interfered by other radio stations. Radio interference from other radio communication stations can greatly affect the telecom operator’s work. The Ministry released the draft of the bill while a disagreement between … [Read more...]

Sirens Fail to Function During Tornado Warning Due to Radio Interference

 

An outdoor warning system failed to function properly during a tornado warning in Hannibal, Missouri on June 28 due to radio interference. Mike Hall, Marion County 911 director, is certain that the radio interference came from HPD traffic. “The city’s 16-siren system is activated through a single radio transmission. A day after the storm, Hall reported a review of the 911 … [Read more...]

User-friendly and Portable RF Safety Device Efficiently Monitors Electromagnetic Fields

 

Microwave Vision Group (MVG) announces the success of its new RF safety device, the EME Guard XS. The EME Guard XS is a small, portable, robust, user-friendly, and economically manufactured RF safety tool that offers high reliability. The device alerts people working near antennas to excessive EMF exposure levels. The device is best suited for people working near antennas, … [Read more...]

Astronomers Unveil View of Galaxy’s Electromagnetic Loop

 

This week at the National Astronomy Meeting (NAM 2015) in Wales, scientists working with the Planck Satellite, including Mike Peel and Paddy Leahy, revealed a new polarization map of the Milky Way in microwaves. This particular view of the electromagnetic loop discovered more than half of a century ago, has never been seen before. “It’s a full sky map showing synchrotron loops … [Read more...]

‘Unstoppable’ New Hacking Device Steals Encryption Keys Out of the Air

 

A group of researchers from Tel Aviv University and the Israeli research center have produced a new hacking device that can steal encryption keys “out of the air.” The device cannot be stopped by disabling Wi-Fi networks or turning off Bluetooth because the device doesn’t use standard communication methods to steal data. The device uses radio waves emitted from computer … [Read more...]

Canted Coil Catalog Describes Benefits for EMI/RFI Shielding

 

Bal Seal Engineering, Inc. released a new 10-page catalog that describes the benefits of canted coil springs for EMI/RFI Shielding. It “provides engineers and designers with detailed information about how canted coil springs can be used to address electromagnetic interference/radio-frequency interference (EMI/RFI) shielding challenges. It describes how the compact, … [Read more...]

Connector Series Includes EMI Shielding

 

Mouser Electronics introduces the Amphenol Pegasus series of twist and lock ‘scoop-proof’ connectors with EMI shielding. “EMI shielding is provided by an electroless copper and nickel plate, and a copper alloy spring finger gasket. Tests show greater than 50db of attenuation for low-end signals (<100Mhz) and greater than 40db of attenuation for high-end signals (<1Ghz),” … [Read more...]

Spaceship Antenna to Prevent Communication Blackouts

 

A team of scientists from the Harbin Institute of Technology proposed a new spaceship antenna to prevent space communication blackouts. The group’s research has been published in the Journal of Applied Physics. The new antenna can prevent communication blackouts in space when spacecraft are coming back into Earth’s atmosphere. “The proposed technique can maintain … [Read more...]

Energy-efficient Electric Car: No AM Radio Due to Possible EMI

 

The BMW i3 Electric Car was the most energy-efficient car sold in the U.S. this year, according to Green Car Reports. However, consumers noticed the car does not offer AM Radio. “AM is not offered due to negative performance influences of the electromagnetic interference of the electric drivetrain. Electric motors cause interference on AM which is why BMW decided to remove … [Read more...]

Saharan Ants Control Electromagnetic Waves to Stay Cool

 

A joint project conducted by Columbia University, The University of Washington and the University of Zürich indicates how Saharan Silver Ants stay cool in one of the hottest climates in the world. The team’s research paper titled ‘Saharan Silver Ants Keep Cool by Combining Enhanced Optical Reflection and Radiative Heat Dissipation’ was recently published in Science … [Read more...]
