Every new 5G device will contain a high-performance 5G chipset and will need to connect to a 5G service provider network. Subscriber quality of experience (QoE) will rely on getting the most out of a device’s features, including battery management, over-the-air radio and antenna performance, and the ability to seamlessly connect to peripheral devices. Shortcomings in any part will lead to poor usability ratings and low adoption by service providers and consumers.

Better Battery Management

Mobile device power requirements range from tens of milliamps when transmitting to nanoamps in sleep mode. Optimizing your device’s power management requires accurate low-power measurement, a million-to-one dynamic range to capture high-power events, and fast power-draw transient analysis.

Our patented power measurement solutions give you the highest precision for optimizing power settings. We also emulate 4G and 5G radio access network (RAN) and channel, so you can simulate your power consumption in real-world conditions.

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.

Leading Device Manufacturers Innovate Early

A leading mobile device manufacturer selected Keysight to accelerate prototyping and development of 5G New Radio (NR) devices. They needed mmWave and over-the-air test solutions that would cost-effectively scale from sub-6 GHz to mmWave and from pre-standards to NR. Keysight provided early access to a comprehensive suite of device validation solutions that met their challenging requirements.
