While there are still interference issues to be resolved, new specifications for Wi-Fi in the 6-GHz band will bring instantly better wireless performance. Eve Danel | LitePoint Wi-Fi technology turns 20 this year, and it has proven to be successful beyond the wildest expectations. The recent announcement by the FCC to consider allowing 1,200 MHz […]
How standards and conformance tests shape the future of 5G New Radio
Specs for 5G NR release-15 have been finalized and plans call for product introductions this year. Sheri DeTomasi | Keysight Technologies, Inc. The development of 5G standards and their commercial rollout appears to be on a fast track. Mobile operators and network equipment makers are conducting field trials and the first smartphones are expected out […]
Test instruments tackle 5G
The high frequencies involved in 5G will force a re-think of how to go about characterizing circuits and systems. Adnan Khan | Anritsu Co. Engineers responsible for designing and manufacturing 5G chipsets, devices, and systems have more than enough challenges. From a technical standpoint, they must deliver high bandwidth, low latency, and other performance benchmarks. […]
Will 5G be lethal?
Leland Teschler, Executive Editor Peruse a certain kind of website these days and you’ll find warnings about the lethality of RF transmissions in the frequency ranges slated for 5G networks. One site quotes Devra Davis, director of the Board on Environmental Studies and Toxicology of the U.S. National Research Council, who warns that our sweat […]
New phase-noise test system works up to 40 GHz with offsets from 0.01 Hz to 160 MHz internally
A new phase-noise measurement system for “power users” helps optimize and prove the performance of new designs, meet operational requirements, as well as remain on schedule and on budget. Phase noise is an unwanted phase modulation noise that emerges in nearly all radio frequency and microwave devices including oscillators, mixers, dividers, multipliers and amplifiers. Power […]
WLAN measurement setup first to support IEEE802.11ac OTA tests via CTIA/WFA CWG Test Plan V. 2.1
The Wireless Connectivity Test Set MT8862A is the industry’s first WLAN measurement solution to support IEEE802.11ac OTA (Over the Air) tests in accordance with CTIA/WFA CWG Test Plan Version 2.1 released in April. With the new support, the MT8862A offers chipset and device manufacturers a comprehensive test tool that can verify WLAN products used in […]
Courseware covers RF microwave circuit design, simulation and measurement
A radio frequency (RF) microwave circuit design, simulation and measurement package provides students with engineering essentials, practical skills and everyday application knowledge to help them successfully develop 5G and IoT wireless applications. Keysight’s RF Microwave Teaching Solution focuses on the complete RF circuit design flow, from specification and simulation, to prototype building and validation, while […]
5G conformance toolset supports validated GCF and PTCRB protocol
Keysight Technologies says its 5G Conformance Toolset now supports the greatest number of validated Global Certification Forum (GCF) and PTCRB protocol, as well as radio frequency (RF) conformance test cases, for both 5G new radio (NR) non-standalone (NSA) and standalone (SA) mode, as reaffirmed at the recent GCF meeting. Protocol and RF conformance tests are […]
O-RAN Alliance develops first open radio access network 5G mmWave radio unit
The industry’s first O-RAN (open radio access network) 5G mmWave radio unit (O-RU) combines essential building blocks to create and test a blueprint for next-generation RAN. “This achievement within O-RAN is exciting because it proves that a radio unit can be built on an open architecture platform,” said Andre Fuetsch, President AT&T Labs and Chief […]
First integrated dual-channel 44-GHz vector signal generator with 2-GHz bandwidth
Keysight’s new VXG microwave signal generators are the first dual-channel microwave signal generators that support up to 44-GHz signals and 2-GHz RF modulation bandwidth in a single instrument. They are designed to address the most demanding wideband millimeter wave (mmWave) applications for 5G and satellite communications by making test set-up less complex and reducing path […]
