Mobile device testing

Mobile device testing from design to production

Wireless device testing is a comprehensive process that verifies whether wireless communication devices – such as smartphones and tablets – work properly, meet performance standards and comply with regulatory requirements. The testing involves several critical domains that ensure a device provides a high-quality user experience and functions correctly within live networks.

Advanced 4G and particularly 5G networks are being continuously extended to prepare for 6G and ubiquitous connectivity. Key enablers include the integration of terrestrial networks (TN) with non-terrestrial networks (NTN), as well as the integration of AI-RAN and other transformative technologies, such as integrated sensing and communication (ISAC). These technologies, together with digital twins, will reshape testing in all development phases.

Wireless device testing is categorized by testing stage: from R&D and conformance to production and even service.

End-to-end testing for mobile devices

Rohde & Schwarz has integrated test solutions that cover the entire wireless device lifecycle, from initial R&D and design verification to conformance approval, production and repair. Our portfolio is engineered to solve the technical challenges of cellular standards (5G NR) as well as major non-cellular standards (Wi-Fi, Bluetooth and UWB). We support the transition to over-the-air (OTA) testing that integrated antenna arrays and millimeter wave architecture demand. Our test solutions range from individual instruments to complete turn-key systems with user-friendly software for seamless automation. We also actively support research endeavors that will shape 6G, the next generation of wireless communications.

Mobile device testing is categorized based on the stage of the product lifecycle and the specific technical domain being evaluated.

Radio frequency (RF) performance testing ensures that the transmitter (TX) and receivers (RX) function correctly and meet performance standards. TX tests evaluate metrics such as output power, error vector magnitude (EVM) quality and spectrum emissions. RX tests characterize performance; the two main metrics are sensitivity (the minimum signal level for reliable decoding) and selectivity (the ability to function in the presence of interference).
Signaling and protocol testing emulates a mobile network environment to verify device protocol implementations and performance parameters using varying network parameters and scenarios. This is essential for verifying how a device handles complex network scenarios, such as dual connectivity (DC), dynamic spectrum sharing (DSS) and standalone (SA) vs. non-standalone (NSA) architecture.
Application performance testing verifies specific service performance by assessing the actual user experience. Measurement parameters include data throughput, latency and power consumption.
Conformance testing is conducted in line with standards defined by regulatory bodies such as GCF and PTCRB. Conformance testing ensures that a device complies with 3GPP specifications. Certification criteria are assessed in four test areas: radio frequency conformance (RF), radio resource management conformance (RRM), protocol conformance (PC) and performance quality analysis (PQA). The testing is essential to interoperability with live networks.
Carrier acceptance tests are specified by some operators to ensure that devices in their network provide the expected functions and performance.
Production testing focuses on high-volume calibration and verification. The tests are often performed in non-signaling mode with chipset-specific interfaces to minimize test time and cost while maximizing yield.
Service and repair require easy-to-use test solutions for service and repair centers. The solutions support the repair, refurbishment and reuse of wireless devices.
