5G Editorial & Guest Opinions

  1. Who Should Get The Billions Collected From Spectrum Auctions? 3/2/2022

    Spectrum auctions yield multi-billion dollar proceeds, but it's not always clear where the money ends up. Now, two parties are vying for a fraction of those funds, one with hopes of upgrading an aging 911 system and the other with providing internet know-how to underserved communities. Both potential recipients could provide vital resources to underserved communities. 

  2. Massive MIMO EMF Exposure Estimation: Tools, Models, And Initial Measurements 8/24/2020

    The introduction of new wireless network technologies necessitates novel approaches to model and estimate the resulting electromagnetic field (EMF) exposure.

  3. 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. Knowles Precision Devices (KPD) supports a wide variety of 5G radio applications.

  4. What Can mmWave Do For 5G Backhaul? 10/9/2019

    The backhaul segment of the network is traditionally made up of the intermediate point-to-point links between the core (or backbone) network and the small subnetworks at the network edge, where the base stations are. Since 5G is aiming for multi-Gbps data rates for subscribers, all this data will need to be backhauled at much higher rates, too.

  5. Packaging For mmWave Devices — Why Do We Need It, And How Do We Do It? 8/19/2019

    Several package types can be used at mmWave frequencies, so the choice will depend on the specific application. However, some general design rules apply to all forms of packaging.

  6. 5G Core Network – Architecture, Network Functions, and Interworking 7/15/2019

    This article is dedicated to describing the main components of the 5G Core Network -- as defined by the 3GPP – including an overview of the architecture, a description of the key individual network functions, and an example of 5G interworking with LTE.

  7. A Look At 3GPP Rel-16: LTE and 5G-NR Enhancements 4/29/2019

    This article discusses the ideas and enhancements currently being developed for 3GPP Release-16, with a focus on selected Rel-16 work items and study items. These enhancements cover not only 5G-NR, but also LTE, which is being advanced in parallel.

  8. Understanding 5G Millimeter Wave Beamforming Test 4/15/2019

    This article explains beamforming in the context of 5G NR specifications, and introduces beamforming characterization and beamforming verification test.   

  9. Power Amplifier MMICs For mmWave 5G 1/14/2019

    This article looks at the semiconductor process and SMT packaging options for the realisation of power amplifier (PA) integrated circuits (ICs) operating at millimeter wave (mmWave) frequencies. It also presents examples of 5G mmWave SMT packaged PA designs.

  10. IMS 2018’s 5G Summit Examines Wireless Networks, Spectrum Policy, Autonomous Driving 6/25/2018

    Much like the 2017 event, this month’s IEEE International Microwave Symposium 2018 (IMS) was abuzz with talk of 5G applications, rollouts, and developments. But nowhere was that focus more singular than Monday’s (June 12) 5G summit, whose speaker lineup looked like a connectivity all-star roster.
