Test and Measurement: Anritsu, Qualcomm verify 5G SA dual connectivity
Anritsu test company said this week that it has tested compliance tests of its 5G NR mobile test platform ME7834NR for dual connectivity in 5G New Radio Standalone mode, which it considers to be first industrial. The system uses a Qualcomm Snapdragon X65 5G modem-RF system.
NR Dual Connectivity (NR DC) allows the device to connect to two 5G NR nodes simultaneously, which according to Anritsu provides higher performance, better coverage and improved latency and reliability. In particular, the company said its test was the first in which NR SA operated at frequencies below 6 GHz and a spectrum of millimeter waves simultaneously, allowing devices to use both the increased coverage of sub-6 and the high data rates that are supported by mmWave.
Anritsu said it has sent the RAN Working Group 5 tests to 3GPP and will present them to the Global Certification Forum and PTCRB at upcoming meetings.

– Advanced wireless research platforms (PAWR) program officially received To the Federal Communications Commission identifying two additional “innovation zones” for wireless research stands in Boston, Massachusetts and Rally, North Carolina. The Raleigh site, in the North Carolina research triangle, has a PAWR test field, which is expected to be released online later this year. The The action of the FCC indicates both this place and the new home of the Colosseum of the Agency for Advanced Research Projects of Defense – the massive software-defined radio station that serves as a virtual battlefield for the three-year DARPA Spectrum Cooperation Challengewhich now lives physically at Northeastern University – as FCC innovation zones, in order to reduce the bureaucracy surrounding the use of FCC experimental licenses in these locations. The definitions of innovation zones will expand the areas in which entities that already have experimental licenses can conduct tests – so if you have an experimental license with permission to operate elsewhere, you can also use an innovation zone and you can conduct multiple unrelated experiments in the area.
-Manufacturer of mobile devices Vivo used Keysight TechnologiesEmulation of the PropSim 5G channel for advanced MIMO tests in the air in the laboratory in mobility scenarios in rural, urban and indoor real conditions.
Keysight also announced a this week a new solution for testing Salesforce implementations which includes artificial intelligence. Its platform for intelligent digital eggplant automation automates over 70% of application testing, according to the company.
“This will accelerate the delivery of high-quality business applications, which is crucial in the world of digital technology,” said Gareth Smith, CEO of Eggplant for Keysight. “These improvements demonstrate our ability to intelligently automate every aspect of the testing lifecycle and deliver high-quality software at a rapid pace.”
-Firm analyst Global industrial analyzers (GIA) forecasts that the global market for general-purpose electronic T&M instruments will reach $ 9 billion by 2024, reflecting a complex annual growth rate of 5.2%. IN recent report, GIA said the market growth is due to the increasing complexity of testing, the adoption of modular test equipment and demand from the telecommunications sector due to the wider distribution and acceptance of broadband, the transition to 5G and the continued demand for LTE test equipment.
The GIA said the United States is the largest regional market, accounting for nearly 32 percent of the world’s total, but China is the fastest-growing region for T&M equipment.
-ICYMI: At Starlink’s Low Earth Orbit (LEO) satellite broadband service can provide download speeds higher than the average cable broadband connection in a number of countries, new numbers from Okla show – although the speed and delay of its upload still do not perform as well as those available on cable networks.

–Rootmetrics also came out with its latest assessment of 5G network operators, from tests conducted in the first half of this year. The first half of 2021 saw an increase in the number of Americans with access to 5G mobile networks and better performance on those networks. With regard to specific carriers, the distinctions continue to be divided between the three national carriers. AT&T won the best awards in the “Best Daily 5G for Every Day” category of Rootmetrics, T-Mobile US was rated the best in 5G availability and was recognized as “excellent” in 5G availability and improved speeds, and Verizon has won for reliability and improved speed and availability.
