Rohde & Schwarz and Nothing Technology partnered to get new 5G capable Nothing Phone (1) market-ready

12 December 2022

Rohde & Schwarz and Nothing Technology joined forces in the research and development (R&D) process to validate the 5G multiband aggregation and the application layer performance for Nothing Technology’s new Phone (1) with the R&S CMX500 one-box signaling tester. This collaboration allowed Nothing Technology to successfully debut the new device, while meeting all the compliance requirements for current and future complex 5G band aggregations and application layer performance.

5G NR improves communications performance with much better speed and reliability, along with lower latency for the end user. The ENDC (E-UTRAN New Radio — Dual Connectivity) deployment method allows user equipment to connect to both 5G NR and 4G LTE networks as a backbone, giving network operators more capacity and enabling a faster 5G rollout. Smartphone manufacturers need to create devices that can globally support countless possible frequency aggregations. As a consequence, 5G multi-carrier and application layer performance needs to be thoroughly tested and validated in the R&D phase. Facing this challenge when developing its first 5G-capable smartphone, newcomer Nothing Technology turned to Rohde & Schwarz and its mobile device testing expertise.

Rohde & Schwarz provided Nothing Technology with the new R&S CMX500 one-box tester, which combines flexibility and superior performance in a single instrument. In the highly integrated test platform, users can test 5G mobile devices and chipsets in all possible 5G NR network deployments and frequency ranges, including FR1, FR2 and LTE bands.

Nothing Technology could speed up testing times and time to market for its Phone (1) by using the R&S CMsequencer shuffler wizard to effectively sweep through the UE FR1 bands/channels and the supporting band combinations, providing throughput and VoLTE/VoNR measurements for each case. This ensured that the mobile device performs as intended in real-world scenarios for each supported band combination. This enabled the expected device experience for the end user when it was launched in July 2022.
