    Qualcomm is facing yet another European Union antitrust case. The wireless hardware giant has revealed in an SEC filing that the European Commission is investigating the company for possible anti-competitive tactics in the radio frequency chip space. Officials want to know if Qualcomm abused its influence in 5G baseband processors to push companies into using its radio frequency front end chips instead of third-party options like Broadcom or Skyworks.

    The UK wants to take down enemy drones and missiles with high-energy light beams. The Ministry of Defense (MOD) announced that it's developing laser and radio frequency weapons. Referred to collectively as Direct Energy Weapons (DEW), they're powered by electricity, operate without ammunition and are fueled by a vehicle's engine or a generator.

  • Phi: a wireless re-routing card that puts you in control of the airwaves (video)

    For all the talk of convergence in mobile devices, there's relatively little chatter about the coming together of wireless signals themselves. In other words, why should we have a separate device to interact with each type of wireless signal? And so, with that intriguing question, begins the pitch for a new device call Phi. It's a $750 antennae-laden PCIe card that slots into a desktop and gathers up wireless signals that are flying around the home -- so long as they have a frequency below 4GHz and don't involve bank-busting neutrinos. The card then allows custom apps to re-direct those transmissions as you like: potentially acting as a "base station" so you can make free calls from your cell phone, or receiving over-the-air HD transmissions which you can play on your tablet, or doing whatever else hobbyists and devs can cook up. Phi is still version 0.1 and Linux-only while the startup behind it -- Per Vices -- looks for a Kinect-style blossoming of third-party interest, but with nothing less than a deity-like command over the domestic ether on offer, how could it ever fail?

  • Uncle Sam's nefarious plot to pwn your garage door

    Republican / Democrat, Christian / Muslim, Team Kristin / Team LC -- despite our many differences, if there's one issue that all Americans can agree on, it's that law-abiding, tax-paying citizens should have unalienable sovereignty over their automatic garage doors. So you can imagine the uproar occurring right now in Colorado Springs, Colorado, ever since the nearby Cheyenne Mountain Air Station (headquarters of the North American Aerospace Defense Command) began testing an emergency radio frequency that has the unintended consequence of pwning numerous garage doors within a 10-mile radius. It would be one thing if the doors just randomly opened and closed on occasion -- smashing a few windshields and delivering a few good laughs -- but apparently the Air Force signal completely flummoxes the garages' RF receivers, often resulting in a pricey house call or an even pricier replacement unit. According to David McGuire, owner of the suddenly-profitable Overhead Door Co, it may be possible to slightly tweak the transmission frequency and put an end to this madness -- an option that Captain Tracy Giles and team are reportedly looking into. While it may be somewhat of an overstatement to call this the most pressing issue that the country has ever faced, if we don't come together as a nation and nip this outrage in the bud, what's stopping Big Brother from waltzing in and breaking our home surveillance cams, car door locks, or -- gasp -- even our remote-controlled projection screens.[Via The Inquirer]
