• Who Should Get The Billions Collected From Spectrum Auctions?

    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. 

  • 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. 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.


iStock-1027833750-air-cargo-plane FAA Issues Flight Notices As 5G Rollouts Stuck In Limbo

A week before the anticipated Jan. 19 rollout of enhanced 5G wireless services, the Federal Aviation Association (FAA) has issued a historically high 1,462 flight notices detailing the potential interference 5G may have on aircraft altimeters. As reported by Bloomberg and Reuters, these notices, called notices to air missions or NOTAMs, were issued to areas around major airports and hospitals with medical helicopter operations.



The new components and technologies required for 5G deployments must provide reliable operation in the presence of real-world noise and interference. Noisecom noises sources generate the broadband noise required to do this type of benchmarking, enabling 5G development and deployment through quantifying component and system performance across the microwave and mmWave bands.

5G New Radio (NR) introduces key improvements on LTE, including more efficient modulation, waveform optimization, and scalable numerology – thus offering advantages such as low latency, faster speeds, and high reliability. In this video, learn about essential requirements for 5G base stations and 5G private network, as well as robust, customizable 5G NR solutions from CommAgility.

Learn more on how a full range of comprehensive testing solutions from Rohde & Schwarz can help you deploy high performance and reliable operations in 5G private networks across various industries, for humans (QoE) and machines (M-QoE) users.

The QPG6100 is a multi-standard Smart Home Communications Controller for ultra-low power wireless communication for Connected lighting applications, switches and other Smart home end nodes, featuring Qorvo’s ConcurrentConnect™ technology; enabling Zigbee, Thread and Bluetooth® Low Energy to operate simultaneously in a single chip design.

The Qorvo QPF4532 is an integrated front end module (FEM) designed for Wi-Fi 6 (802.11ax) systems. The compact form factor and integrated matching minimizes layout area in the application.


  • As a humorous introduction, Rohde & Schwarz was motivated to write this white paper because vehicles are turning into “smartphones on wheels”, especially when considering the massive proliferation of wireless communications in automotive applications.

  • In this whitepaper we use Remcom’s Wireless InSite 3D Wireless Prediction Software to simulate the level of interference received at the radar altimeter input port of a landing aircraft due to emissions from 5G base stations which are in the vicinity of the approach to runway 27L at Chicago O’Hare International Airport. 

  • As well as the mobile networks we are all familiar with, wireless technologies have found numerous applications across industry, transport, military and satellite communications. In the past, many of these applications would have used proprietary network standards, but increasingly they are based around protocols from the commercial world.

  • The document discusses the role of holdover and its evolution from legacy SONET/SDH networks, which depend on frequency synchronization up to modern 5G mobile telecommunication that rely on frequency, phase, and time synchronization using IEEE 1588.

  • To meet 3GPP specifications, a 5G New Radio (NR) implementation must meet demanding processing requirements and RF capabilities. Compared to LTE, this results in a need for higher performing, more flexible 5G NR hardware.
