The radio modem chipset is a key component of 5G devices and access points that connect the next-generation network. Our chipset solutions span the network stack, including design and simulation tools, physical layer measurement, high-speed digital standards testing, channel emulation, network emulation, user equipment (UE) emulation, and over-the-air (OTA) testing.

Design and Automation Software

Our electronic design automation (EDA) software products span the application space including high-speed digital, mixed-signal, RF, microwave, and millimeter-wave analog design. Perform electrical, electromagnetic, and thermal simulations of your most complex circuits in a software ecosystem that enables easy test and measurement design and performance verification. Reduce the risk of chip spins and board turns.

Precision High-Speed Digital Interfaces

Mobile device chipset and component integration relies on a collection of high-speed digital specifications. Antennas, chipsets, peripherals, and processors rely on different digital standards to ensure high-bandwidth data transmission without excess power consumption or electromagnetic interference (EMI).

Every generational change of the digital standards used in mobile devices is a potential risk to the performance of your device and your timeline for product introduction. Keysight sits on steering committees and boards of many standards bodies, and our experience testing interconnect standards reduces this risk and helps you accelerate your product introductions.

Make sure you are testing your design against the latest digital interconnect standards to minimize design risk and maximize chipset performance. See Keysight's solutions for the following standards:

RF and Radio Resource Management Testing

5G mobile devices will combine familiar sub-6GHz bands with new MIMO antenna systems, as well as high-frequency millimeter-wave (mmWave) bands with highly-focused beam-steering. With different global spectrum assignments and the need for devices to operate in both non-standalone and standalone use cases, the chipset test matrix is enormous. Device RF testing goes much faster if the device designer is using the same channel and traffic emulation as the carrier architect and chipset designers.

Performing device design-verification testing, radio resource management (RRM), and RF pre-conformance is faster when you use pre-built carrier-compliant test scenarios. Thoroughly test the parametric performance, physical layer, and protocol functionality of your device’s chipset using the same emulated network and channel used by the carriers.

Error Vector Magnitude (EVM) is a one of many key figures of merit measuring noise, interfering signals, and nonlinear distortion. For any key figure of merit of this type, your 5G R&D testbed needs to be significantly better than the device you are measuring. For any of your design's key figures of merit, make sure you are measuring using the same depth as your mobile operator's network equipment manufacturer.

5G Protocol Testing

Every new device carrying a new 5G chipset will have a list of testing to perform: feature bring-up, functional testing, negative testing, regression testing, KPI testing, data throughput test, and overall device performance test.

Make sure your protocol test solution has the most complete protocol stack available on a software platform with fully-developed, carrier-based test cases. You need a single system that handles RF, intermediate frequency (IF), and mmWave frequencies in the most realistic replication of a real-world environment.

5G Chipset Makers Innovate Early

Qualcomm Technologies selected Keysight's 5G Protocol R&D Toolset to achieve an industry-first 5G data connection with its Snapdragon™ X50 5G modem chipset. Using a powerful 5G emulation platform allows developers to analyze complex channel conditions more completely and debug unexpected behavior faster.

“Reaching this significant milestone combines the expertise of both companies in driving toward the commercial launch of 5G in 2019,” added Serge Willenegger, senior vice president, product management, Qualcomm Technologies, Inc. “We are delighted to work together with Keysight in helping to accelerate our delivery of enhanced mobile broadband experiences to consumers.”

Emulating real-world radio channel conditions

Once you’ve demonstrated stability and high data rates in clean and ideal channel conditions, your next challenge includes validating the mobile device or base station performance under real-world conditions where the channel is non-ideal, complex, faded, and filled with interference. 

 

Make sure you have access to the most reliable tools for characterizing end-to-end system performance of base stations and mobile devices across all 5G NR signal bandwidths and CA schemes by emulating real-world complex 3D fading and interference channel conditions in your lab.
