  1. Simplifying 5G Radio Design With A New Range Of 28 GHz Bandpass Filters 6/3/2020

    As 5G innovation forges on, radio systems continue to emerge. Each system has a range of requirements, including specific RF filter performance needs, and it’s up to the 5G FR2 Ecosystem of suppliers to meet that demand. In response, Knowles Precision Devices (KPD) supports a wide variety of 5G radio applications.

  2. Ultra-Wideband And Contact Tracing 101 6/3/2020

    Ultra-Wideband (UWB) is a wireless technology that enables unprecedented accuracy in real-time measurement of location and distance: it can accurately determine a device's location within centimeters, both indoors and outdoors.

  3. edgeBoost™, bandBoost™ And coexBoost™ – Three Types Of Wi-Fi Filters 6/3/2020

    These days, Wi-Fi designs often include filters. This paper addresses what types of filters are used and for what purposes.

  4. 5 GHz Wi-Fi Coexistence With 5G Cellular For Improved User Experience 6/2/2020

    The ever-increasing demand for higher data rates and reduced buffering times has driven the continuous evolution of cellular communication and transmission. 5G promises to take performance to levels never seen before, with mounting pressure to deploy 5G handsets faster than any previous cellular standard.

  5. The Week in 5G: 5/26/2020 —Huawei’s “Breakthrough” Antenna; Shanghai’s 5G Phone Booths 5/26/2020

    Plus, Australia trials mmWave 5G mobile phone technology, the Thai government convenes a 5G rollout committee, South Korea's KT brings autonomous intelligent vehicles to its logistics center, and more, all in this edition of the Week in 5G.  

  6. The Week in 5G: 5/19/2020 — Cell Tower Attacks Come to US; Verizon Called Out for Misinformation in Ads 5/19/2020

    Plus, the US FCC attempts to shore up rural 5G rollouts, two of China's big three telecoms hitch their wagons to Ericsson, and more, all in this edition of the Week in 5G. 

  7. From The 1920s To The 2020s – Bandwidth Has Always Been King 5/15/2020

    Over time, the telephone replaced the telegraph, and now cellular and voice over Internet protocol (VoIP) technology are replacing the landline. As more communication is done wirelessly and over the Internet, we are becoming more interested in increased bandwidth. This is because bandwidth places a limit on how quickly we can send information through a channel such as an optical fiber or a section of the radio spectrum.

  8. Facing 5G NR Test Challenges 5/13/2020

    With initial 5G trials and deployments now using the official 3GPP standard,design laboratories and conformance test facilities are facing the struggle to deliver user equipment, fixed-wireless access (FWA), and customer premise equipment (CPE) verified to meet this standard, and also to anticipate the next steps in 5G technology, the 3GPP standard, and corresponding test requirements.

  9. Medical Imaging Quality Starts By Selecting The Right Components 5/13/2020

    MRI machines use a strong magnetic field and computer-generated radio waves to produce cross-sectional images. Thus, the quality of the MRI depends on the uniformity of the magnetic field and the radio components inside it.

  10. The Week in 5G: 5/12/2020 — Huawei, Automakers form 5G “Ecosystem” Alliance; Australia Eyes 850 MHz and 900 MHz Bands for 5G 5/12/2020

    Plus, science deniers' crusade against 5G continues, Qualcomm touts a new processor, New Zealand forgoes an auction and assigns 5G spectrum directly, and more, all in this edition of the Week in 5G.
