Test and Measurement: Rohde & Schwarz boost Wi-Fi 6 chipset testing with Broadcom


Rohde & Schwarz recently announced that it has put together tailored test solutions for Broadcom’s Wi-Fi 6E chipsets, which operate in the 6 GHz band. In collaboration with Broadcom, R&S said that its new R&S CMP180 wireless device test platform has been validated for Broadcom’s new chipsets.

The test company noted that some of the features of Wi-Fi 6E, such as its particularly wide bandwidth and the use of 1024QAM modulation, can prove challenging for test and measurement equipment. R&S said that the CMP180 has been validated for characterizing Broadcom Wi-Fi 6E chipsets at the radio-frequency level for tests including error vector magnitude (EVM), timing measurements and spectrum emission compliance.

“We are happy to provide tailored test solutions that help Broadcom’s customers bring the newest Wi-Fi technology to the market,” said Christoph Pointner, SVP of mobile radio testers at Rohde & Schwarz. “The joint efforts with Broadcom for Wi-Fi 6E also provide a solid foundation to enhance our test solution for next-generation Wi-Fi 7, which will leverage on the 6 GHz band to deliver higher performance and throughput.”

In other test news:

Netscout said this week that it worked with AWS to support the migration of workloads and services of ENGIE IT, the IT subsidiary of low-carbon energy supplier ENGIE, to the cloud.

Netscout noted that moving such workloads to the cloud “requires continuous monitoring before, during, and after the migration process”, and its solutions are able to do so because they are interoperable with various core technologies of AWS.

“We turned to Amazon to migrate our workloads and provide us with the flexibility and agility we need, while Netscout ensures our ability to maintain the highest service levels,” stated Anthony Schmitt, network manager for ENGIE IT. “Since Netscout designed its solution to monitor enterprise and service provider workloads that run on AWS core technologies, we were confident that our migration would adhere to our strict service performance and security standards. We were also impressed that we achieved multi-gigabyte traffic processing speeds with the Netscout VStream appliance.”

Anritsu said that it won GCF approval for industry-first Release 16 protocol conformance tests for 5G New Radio (NR) at GCF’s Conformance Agreement Group meetings held in October 2021. The tests were verified on Anritsu’s 5G NR Mobile Device Test Platform ME7834NR. Anritsu added that the conformance tests had been previously verified by 3GPP’s Radio Access Network Working Group 5, and it has also submitted them to the PTCRB’s validation group.

-In other company news, Rohde & Schwarz reported recently that it is supporting China Mobile’s Voice over New Radio testing of audio quality. Rohde also has a virtual event coming up on January 25-27, its Demystifying EMC event that is in its eighth year. The conference will be held virtually again this year.

Gogo Business Aviation has completed construction of a seven-tower 5G testbed for testing connectivity for aircraft. “These seven sites will serve as a testbed for our 150-tower nationwide network,” said Mike Rupert, vice president of network operations for Gogo Business Aviation. “The testbed includes sites in both remote and populated locations in order to validate the network is operating as designed in all types of environments.” Read the full story here.

Google Cloud IDS simplifies virtual private cloud network threat detection


Developed with Palo Alto Networks, Google Cloud IDS is now available in all regions, according to a statement from the company; Google Cloud IDS debuted as a preview over the summer

Google Cloud announced the general availability of Google Cloud Intrusion Detection System (IDS), a cloud-native managed network security solution. Google Cloud IDS aims to simplify network security that up to now required a patchwork of third-party and open-source solutions, according to Google Cloud.

“Cloud IDS delivers cloud-native, managed, network-based threat detection. It features simple setup and deployment, and gives customers visibility into traffic entering their cloud environment (north-south traffic) and into traffic between workloads (east-west traffic). Cloud IDS empowers security teams to focus their resources on high priority issues instead of designing and operating complex network threat detection solutions,” said Google.

“Google Cloud customers will be able to deploy on-demand application visibility and threat detection between workloads or containers in any Google Cloud virtual private cloud (VPC) to support their compliance goals and protect applications,” said Palo Alto Networks Senior Vice President Muninder Singh Sambi in a separate post.

Google Cloud VPC threat detection preceding Google Cloud IDS was limited in its scope, he said. It was also complex to design and implement, and—most crucially for cloud-native businesses—couldn’t scale dynamically to handle cloud bursting events, which are necessary to handle peaks in IT demand.

“Until now, detecting threats in traffic between workloads within the trust boundary of a VPC has been a significant hurdle for cloud network security teams, leading to compliance challenges and blindspots for the Security Operations Center (SOC),” he said. 

“The Palo Alto Networks ML-powered threat analysis engine processes over 15 trillion transactions per day, automatically collected from across our global network of firewalls and endpoint agents. The result is 4.3 million unique security updates made per day to ensure you’re covered against the latest threats,” said Sambi.

Worldwide Google Cloud IDS rollout following preview

Google Cloud IDS comes at at time when hyperscalers including Google, Amazon and Microsoft are rapidly increasing their global Wide Area Network (WAN) footprints. Businesses are increasingly turning to the public cloud as more companies pivot to being cloud-native or at least cloud-adjacent.

In December Google announced plans to push into Germany, Israel, and Saudi Arabia with new cloud regions planned in 2022. Those join 29 cloud regions and 88 zones already in use.

Snapdragon Tech Summit—The capital of the modern


Editor’s note: Qualcomm provided travel, lodging and other accommodations associated with the Snapdragon Tech Summit.

KONA, HAWAII–Aside from being the most fun, informative and collaborative annual technology event, Qualcomm’s Snapdragon Tech Summit is also one of the most important. While the focus is primarily on the latest and greatest SoCs that will power premium-tier Android smartphones, there’s a much broader context of how foundational innovation that improves the way we interact with our mobile devices will permeate a range of categories leading to more personal, immersive and productive experiences. 

Being at the Fairmont Orchid on the Big Island’s eastern coast feels for me like what it must’ve felt like to be in Paris in the mid-1920s. Instead of Piet Mondrian and Wassily Kandinsky shaping the trajectory of visual art, Cristiano Amon and Hugo Swart share a vision for a connected present and future with socioeconomic implications too sweeping to articulate. Instead of James Joyce and Vladimir Nabokov changing the concept of what prose can be, Jeff Gehlhaar and Ziad Asghar explain the contours of how pervasive artificial intelligence tools can make our personal and professional lives fundamentally better. 

Pablo Picasso, Gertrude Stein, Henry James, Isadora Duncan, Max Ernst, Josephine Baker, and the rest of the Paris intelligentsia who co-existed and co-created between the wars all have technologist analogs. And they’re all here. In his brilliant historiography The Free World: Art and Thought in the Cold War, Louis Menand describes this remarkable time and place: “For a small group of people, however, Paris…represented a set of values that had supreme status in mid-century art and thought: it was the capital of the modern.”

For these fleeting days in late November/early December on the Hawaiian archipelago, Qualcomm creates the capital of the modern. 

A recurring sentiment shared throughout the event was how nice it was to be back in person—sharing meals, drinks, memories, and ambitions. Spending long days with the insightful analysts that help inform my work and the gifted journalists who challenge me to do my work better is refreshing. Chatting with Qualcomm’s incredibly hard-working and talented communications and marketing teams—the people who make it possible for me to do the job that is my remit—is a delight. Sharing personal stories like mine and my partner’s struggle with fertility, IVF journey and now pregnancy, and then receiving supportive feedback and constructive advice from colleagues who have traveled that same road, is, frankly, overwhelming. 

While there are obviously varying degrees of receptivity to the information being shared, and different opinions on the impact that will be had, what you see here are people committed to bringing innovation to bear on our world. That’s a difficult job and one that never ends or slows down. But it has to be done and Qualcomm is doing it. Reflecting on my experience at Snapdragon Tech Summit, I’ll borrow again from Menand. “Every time you open a door, there’s a whole story behind it.”
