  1. Ricocheting Radio Waves Monitor The Tiniest Movements In A Room

    Relief may be on the horizon for anyone who has ever jumped around a room like a jack-in-the-box to get motion-sensing lights to turn back on. A new motion sensor based on metamaterials is sensitive enough to monitor a person’s breathing.

  2. 'Building Up' Stretchable Electronics To Be As Multipurpose As Your Smartphone

    By stacking and connecting layers of stretchable circuits on top of one another, engineers have developed an approach to build soft, pliable “3D stretchable electronics” that can pack a lot of functions while staying thin and small in size. The work is published in the Aug. 13 issue of Nature Electronics.

  3. FCC Proposes Steps Towards Auction Of 37 GHz, 39 GHz, And 47 GHz Bands

    The Federal Communications Commission recently proposed next steps to prepare the upper 37 GHz, 39 GHz, and 47 GHz bands for auction. In particular, auctioning the 39 GHz and upper 37 GHz bands together presents a critical opportunity for 5G deployment as it represents the largest amount of contiguous spectrum available in the millimeter-wave bands.

  4. NASA Studies Space Applications For GaN Crystals

    Two NASA teams are examining the use of gallium nitride, a crystal-type semiconductor compound first discovered in the 1980s, and currently used in consumer electronics such as laser diodes in DVD readers.

  5. The Week In 5G: 8/8/2018 – FCC Implements 'One-Touch, Make-Ready' Pole Access, Vows To Preempt Local Laws Blocking 5G Deployment

    The FCC is moving to drop barriers to 5G deployment in the U.S., Motorola touts phones' bolt-on 5G capability, and Australia preps for a spectrum auction, all in today's The Week in 5G!

  6. The Week In 5G: 8/14/2018 – FCC Claims US Poised To Win 5G Race, New Report Suggests China Has The Edge

    FCC Commissioner Brendan Carr says the United States is in "great shape" to win the global 5G race, but China has more cell sites and has heavily outspent the U.S. on infrastructure; Ericsson ups its U.S. commitment; and the Philippines gets its first 5G test network, all in today's The Week In 5G

  7. These Tags Turn Everyday Objects Into Smart, Connected Devices

    Engineers have developed printable metal tags that could be attached to everyday objects and turn them into “smart” Internet of Things devices.

  8. Cognitive Radio Technology Optimises Use Of Spectrum In Wireless Networks

    The growing popularity of wireless networks has highlighted the need to increase network capacity and efficiency. Cognitive radio-based networks have attracted increased attention and have been studied in depth to overcome the problem of spectrum scarcity in next-generation wireless communication systems.
