5G EDITORIAL & GUEST OPINIONS

• Massive MIMO EMF Exposure Estimation: Tools, Models, And Initial Measurements

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

• Simplifying 5G Radio Design With A New Range Of 28 GHz Bandpass Filters

  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.

• What Can mmWave Do For 5G Backhaul?

  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.

• Packaging For mmWave Devices — Why Do We Need It, And How Do We Do It?

  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.

• 5G Core Network – Architecture, Network Functions, and Interworking

  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.

• A Look At 3GPP Rel-16: LTE and 5G-NR Enhancements

  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.
