Test and measure: Anritsu and Qualcomm verify 5G SA dual connectivity


Testing company Anritsu said this week that it has verified protocol compliance testing on its 5G NR ME7834NR mobile device test platform for dual connectivity in 5G New Radio Standalone mode, which it says , is an industry first. The system uses Qualcomm’s Snapdragon X65 5G RF modem system.

NR Dual Connectivity (NR DC) allows a device to connect to two 5G NR nodes at the same time, which Anritsu says provides higher throughput, better coverage, as well as improved latency and reliability. Specifically, the company said its test is the first where NR SA operates on both frequencies below 6 GHz and a millimeter wave spectrum at the same time, allowing devices to take advantage of both the increased coverage of frequencies below 6 and high data speeds which are supported by mmWave.

Anritsu said they have submitted the tests to 3GPP’s RAN 5 Working Group and submit them to the Global Certification Forum and the PTCRB at future meetings.

In other test news:

-The Platforms for advanced wireless research (PAWR) officially received the Federal Communications Commission designation of two additional “innovation zones” for wireless research test beds in Boston, Massachusetts and Raleigh, North Carolina. The Raleigh site in North Carolina’s Research Triangle has a PAWR test bed under construction that is expected to go live later this year. FCC action points to both this location and the Defense Advanced Research Project Agency’s new Coliseum headquarters – the massive software-defined radio test bed that served as a virtual battlefield for the DARPA Spectrum Collaboration Three-year challenge, which now resides physically at Northeastern University. – as FCC innovation zones, with the aim of reducing the red tape associated with the use of experimental FCC licenses in these locations. Innovation zone designations will expand the areas in which entities that already have experimental licenses can test – so if you have an experimental license with permission to operate elsewhere, you can also use an innovation zone, and you can conduct several unrelated experiments in the area.

Keysight also announced this week a new solution for testing Salesforce deployments that incorporates artificial intelligence. Its Eggplant Digital Automation Intelligence platform automates more than 70% of application testing, according to the company.

“This will accelerate the delivery of high quality business applications, which is essential in a digitally driven world,” said Gareth Smith, general manager of Eggplant for Keysight. “These enhancements demonstrate our ability to intelligently automate all aspects of the test lifecycle and deliver high quality software quickly. ”

– Analyst firm Global Industry Analysts (GIA) predicts the global general-purpose electronic T&M instrument market to reach $ 9 billion by 2024, reflecting a compound annual growth rate of 5.2%. In a recent report, the GIA said that the market growth is driven by the increasing complexity of testing, the adoption of modular test equipment, and the demand from the telecommunications industry due to the deployment and adoption of high more widespread throughput, the transition to 5G and the continued demand for LTE. test equipment.

GIA said the United States is the largest regional market, accounting for nearly 32% of the global total, but China is the fastest growing region for T&M equipment.

-ICYMI: by Starlink Low Earth Orbit (LEO) broadband satellite service may provide faster download speeds than average wired broadband in a number of countries, new numbers Ookla show – although its download speeds and latency still don’t perform as well as those available on wired networks.

Rootmetrics also released its latest assessment of operators’ 5G networks, based on testing in the first half of this year. The first half of 2021 saw a growing number of Americans with access to and better performance on 5G mobile networks. In terms of specific carriers, the honors continue to be distributed among the three national carriers. AT&T took top honors in Rootmetrics’ “Best Daily 5G” category, T-Mobile US was ranked best in 5G availability and recognized as having “excellent” 5G availability and improving speeds, and Verizon took home the award for reliability and improved speeds and availability.
