Nothing Phone test (1) with Rohde & Schwarz CMX500 tester

Nothing Technology validates its new 5G Nothing Phone (1) with Rohde & Schwarz CMX500 tester

  • Nothing Technology has validated the 5G multiband aggregation capability and the application layer performance of its new Phone (1) with the R&S CMX500 single-box signaling tester from Rohde & Schwarz.
  • This enabled Nothing Technology to bring to market its new smartphone that meets all compliance requirements for current and future 5G complex band aggregation 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 which 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. In the 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.
