The Wi-Fi Evolution
By Ahmad H. Abdelmajid, Qorvo

If you are looking to buy a new wireless networking gear or a mobile device, you may be overwhelmed by too many choices and abbreviations. Since Wi-Fi was first released to consumers in 1997, its standards have been continually evolving, typically resulting in faster speeds and network/spectrum efficiency. It can be difficult to keep track of new standards. This paper is meant to help you understand the basics of Wi-Fi standards, and provides an overview of the evolution of Wi-Fi technologies.

Making 5G Work: Accelerating Testing Across The Workflow To Put 5G Devices In The Hands Of Customers
White Paper | Keysight Technologies

5G represents an exponential increase in technical complexity with challenges coming from 5G new radio (NR), massive multiple input multiple output (MIMO), millimeter-wave (mmWave) frequencies, and over-the-air (OTA) test methods. This paper includes useful tips to help manufacturers accelerate time to market across the 5G workflow and reach first-to-market status.

Understanding Microstrip Filter Topologies
White Paper | Knowles Precision Devices DLI

The behavior of transmission lines in RF systems becomes important when the transmitted frequency’s wavelength is short enough that the length of cable becomes a significant part of a wavelength. Microstrip consists of a conducting strip separated from a ground plane by a dielectric substrate. 

Introduction Into Theory Of Direction Finding
White Paper | Rohde & Schwarz GmbH & Co. KG

While direction finding for navigation purposes is becoming less important, there is a growing demand for determining the location of emitters as the mobility of communications equipment increases. The importance of direction finding lies in the fact that spread-spectrum techniques are increasingly used for wireless communications.

Throughput Of A 5G New Radio FD-MIMO System In An Urban Area Using Custom Beamforming
Application Note | Remcom

Wireless InSite's high-fidelity MIMO calculations predict system throughput and bit error rate.  This example demonstrates throughput analysis between three small-cell base stations employing FD-MIMO beamforming to User Equipment (UE) moving along a route, using 5G New Radio in a dense urban environment.
