Vancouver Café Blocks Wireless Signals
A new pop-up café in Vancouver, Canada is offering patrons a temporary escape from digital communication. Julien Thomas, a Vancouver construction worker and social artist, is opening The Faraday Café in Vancouver’s Chinatown with assistance from Hughes Condon Marler Architects. The café, which will be open July 2-16, is named after the Faraday cage, an enclosure made of a … [Read more...]
FCC Requests Input on LTE/DTV Interference Mitigation
The Federal Communications Commission’s Office of Engineering and Technology (OET) is asking for additional input on evaluations of potential interference from wireless LTE affecting DTV stations conducted recently by OET engineers. The FCC announced in October 2012 it would be hosting incentive auctions as a means to reallocate broadcast television spectrum for wireless … [Read more...]
Congress Pushing for Grid Vulnerability to EMP Assessment
Congress has expressed interest in learning more about the capabilities of America’s adversaries to damage the nation’s power grid. Watchdog.org reports an intelligence authorization bill passed by the House of Representatives last month includes a provision directing the director of national intelligence to submit to Congress “a report on the threat posed by man-made … [Read more...]
Software Optimizes Wind Farm Location to Reduce Telecom Interference
Researchers collaborating on the SOPCAWIND project have developed software to optimize wind farm placement, in order to reduce noise, environmental impact, and telecommunications interference. Wind farms, while a valuable and viable source of energy, reportedly meeting up to 8 percent of Europe’s energy needs, are accompanied by significant drawbacks; namely, noise … [Read more...]
ESA Battles Interference Affecting Climate Change Satellites
The European Space Agency (ESA) announced that it was recently forced to change the frequencies used by some of its satellites in order to work around interference emitted from Earth-bound wireless communication installations, some of which are illegal. At a recent briefing to London’s Royal Society dedicated to discussing the results of ESA satellites compiling data on … [Read more...]

NASA Uses Laser to Beam HD Video from International Space Station
NASA successfully beamed a high-definition video from the International Space Station to Earth last Thursday using a new laser communications instrument. The 175-megabit video transmission of “Hello, World!” was the first of its kind for the Optical Payload for Lasercomm Science (OPALS), a technology demonstration that allows NASA to test optical communications—also known as … [Read more...]
Chip Cancels On-Channel RF Interference
Researchers at the University of Twente in the Netherlands have created a new chip designed to cancel on-channel interference using an adaptive beamforming technique. While the ability to make such a device has already existed for some time, the UTwente chip can be manufactured more cheaply and economically than any of its predecessors. The device, developed by postgraduate … [Read more...]
