Key Terms

cm-wave spectrum technical

The cm-wave spectrum is the band of radio frequencies with wavelengths measured in centimeters (roughly 3 to 30 gigahertz), used to carry wireless signals for services like mobile broadband, fixed wireless, and some satellite links. For investors it matters because access to these frequencies affects a company’s ability to deliver high-speed connections and network capacity — think of different frequency bands as highway lanes where higher frequencies can carry more traffic but over shorter distances.

multiple-input, multiple-output (mimo) technical

A multiple-input, multiple-output (MIMO) system uses multiple transmitters and receivers to send and receive data at the same time, boosting wireless capacity and reliability. Think of it like adding more lanes and traffic lights to a road so more cars can travel faster and with fewer jams; for investors, MIMO technology can raise the value of network equipment, chips, and devices by enabling faster speeds, better coverage, and new services that drive demand and revenue.

interoperability testing technical

Interoperability testing checks whether different software, devices or systems can connect and work together reliably, like testing whether new appliances fit and run on a household’s existing outlets and wiring. Investors care because successful interoperability lowers the risk of costly fixes, speeds product adoption and regulatory acceptance, and can protect revenue and market share by ensuring offerings plug smoothly into customers’ existing setups.

protocol efficiency technical

Protocol efficiency measures how well a defined set of steps, rules or technical procedures produces the intended result while using the least time, money and resources. For investors it matters because higher efficiency typically means lower costs, faster delivery, fewer delays or errors and a better chance of meeting regulatory or market milestones—think of it like a fuel-efficient car that goes farther on less gas, improving returns and predictability.

user equipment (ue) technical

User equipment (UE) is the physical device a person or machine uses to connect to a mobile network, such as a smartphone, tablet, hotspot, modem, or connected sensor. Investors watch UE metrics because the number, type, and capabilities of these devices drive demand for wireless services, network upgrades, and revenue from device sales and subscriptions—think of UE as the customer’s gateway that determines how carriers and equipment makers earn and invest.

key performance indicators (kpi) technical

Key performance indicators (KPIs) are measurable numbers that track how well a business is reaching its most important goals—examples include sales growth, profit margin, customer retention and production efficiency. They matter to investors because KPIs act like a car’s dashboard: they reveal whether a company is on course, accelerating, or encountering problems, helping investors assess performance, compare peers and anticipate future results.

Collaboration demonstrates full-stack pre-6G interoperability testing using real network infrastructure and devices

SANTA ROSA, Calif.--(BUSINESS WIRE)-- Keysight Technologies, Inc. (NYSE: KEYS) and Ericsson have collaborated to troubleshoot and validate interoperability between an Ericsson pre-6G base station (gNB) and prototype pre-6G devices, using Keysight’s WaveJudge Wireless Analyzer Solutions. The work demonstrates full-stack pre-6G interoperability testing using real network infrastructure and devices, supporting early validation of emerging 6G concepts as standards development continues. The collaboration will be demonstrated live at Mobile World Congress Barcelona 2026.

As 6G standardization efforts begin, the industry increasingly needs to validate early implementations against evolving specifications. Pre-standard 6G systems are exploring new concepts such as cm-wave spectrum, wider channel bandwidths up to 400 MHz, massive Multiple-Input, Multiple-Output (MIMO) performance gains, and improved protocol efficiency. Interoperability testing between prototype base stations and devices is particularly complex due to differences in design choices and interpretations of draft standards, making it difficult to identify root causes of performance or signaling issues.

Keysight addresses these challenges with its WaveJudge Wireless Analyzer Solutions, which acts as an independent third-party solution to decode and analyze signaling from both the gNB and UE. WaveJudge highlights discrepancies between expected and actual behavior, enabling faster issue identification and resolution between vendors. The solution provides detailed multi-layer analysis and KPI insights, allowing engineers to evaluate link performance, verify advanced features, and quantify the benefits of emerging 6G technologies.

David Bjore, Vice President and Head of RAN Software & Compute Platforms, Business Area Networks, Ericsson, said: “Achieving interoperability is a key milestone for our 6G program. Our collaboration with Keysight has helped us resolve issues more efficiently and gain deeper insight into the performance of emerging 6G concepts.”

Lucas Hansen, Vice President and General Manager, Wireless Devices, and Operators at Keysight, said: “Early validation is critical to advancing next-generation wireless. By working closely with Ericsson, we are enabling early exploration of new ideas alongside the standards development process. Keysight’s WaveJudge solutions help identify issues quickly and accelerate our customers’ path from research to real-world deployment.”
