  1. Is Your Spectrum Monitoring Tool Prepared For Modern Communication Technologies?
    9/8/2017

    Radio frequency (RF) spectrum is one of the most sought-after resources in the world. In the U.S., public spectrum auctions by the government generate billions of dollars for the right to utilize spectrum bands. 

  2. 802.11ax: 5 Things To Know
    9/7/2017

    The current Wi-Fi standard, 802.11ac, works very well in a home environment. However, as with previous Wi-Fi standards, it may reach its limits around 2022 when there could be up to 50 nodes in a home. The 802.11ax network is the next evolution in the IEEE 802.11 Wi-Fi standard and will become prevalent in very dense environments, such as urban apartment complexes, college campuses, concert venues, or sports stadiums, where many clients will access the internet over Wi-Fi. This article presents five key aspects of the new 802.11ax network and the next generation of Wi-Fi.

  3. Tiny Membrane-Based Acoustic Antennas Could Shrink Electronic Devices
    8/25/2017

    Nanoelectromechanical system (NEMS) antennas that resonate with acoustic waves, rather than with electromagnetic waves alone, could significantly reduce the size of electronic devices, according to a team of scientists at Northeastern University in Boston.

  4. Smart Homes For Seniors: How The IoT Can Help Aging Parents Live At Home Longer
    8/23/2017

    The population of adults 85 and older in the U.S. will roughly triple between 2015 and 2060, making it the fastest-growing age group over this time period. This has become a major concern for families taking care of seniors who will be living on their own. Qorvo’s Senior Lifestyle System has been tested and used for the last 15 years in assisted living communities in Europe to help seniors live more independently. Within a few weeks, this system learns the routine day-to-day activities of the senior resident, provides intelligent status updates in a dashboard app, and sends alerts to designated caregivers if something unexpected happens.

  5. Ultra-Thin Diselenides Could Supplant Silicon In Next-Generation Electronics
    8/16/2017

    Layered two-dimensional materials that are as efficient, but thinner than, silicon semiconductors, could power future electronic circuits and devices, according to Stanford researchers.

  6. Africa's Old Communication Antennas Reborn As Radio Telescopes
    7/14/2017

    Ghana says it has successfully refurbished and converted an old telecommunications antenna into a radio telescope, one of several radio-based antennas that will comprise the African Very Large Baseline Interferometer (VLBI) Network (AVN).

  7. World's First Wirelessly Charged Laptop Hits Shelves

  8. mmWave Channel Modeling With Diffuse Scattering In An Office Environment
    6/30/2017

    To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. This example uses Wireless InSite’s diffuse scattering capability to perform simulations of an indoor wireless network.

  9. Designing A Broadband L-band 160 W GaN Power Amplifier Using SMT Packaged Transistors
    6/30/2017

    Advancements in Gallium Nitride technologies are leading to amplifier operation at higher powers, supply voltages, and frequencies. The whitepaper includes load-pull measurements, thermal considerations, and EM simulations of the input/output matching networks.

  10. A Better Way To Market Internet Of Things: Smart Home Butler
    6/30/2017

    The smart home revolution has taken a lot longer to get up and running due to the disagreements over what protocols and platforms should be used in the base technologies, as well as the poor choices in consumer words like “smart home” and “IoT.”
