5G data call based on 3GPP release 16 specifications
Keysight Technologies has announced that Samsung Electronics’ System LSI Business has selected its 5G test platforms to establish a 5G data call based on 3GPP release 16 (Rel-16) specifications.
Samsung selected Keysight’s 5G network emulation systems to successfully demonstrate a data link based on 3GPP Rel-16 specifications for the 5G new radio (NR) standard. Finalized in 2020, Rel-16 brings numerous enhancements to 5G NR deployments, leading to improved spectrum use, lower network latencies and higher connection reliability. Such improvements are critical to machine-to-machine (M2M) communications in industrial automation, autonomous vehicles and greater operational efficiencies for service providers.
Samsung used Keysight’s 5G Protocol R&D Toolset and Test Application software to validate its Exynos Modem chipset, which many global device makers use to bring 5G products to market. The toolset enables Samsung to perform 3GPP Rel-16 physical player interoperability development testing (IODT), verify power saving IODT performance and validate new radio to new radio dual connectivity (NRDC) functionality, in both sub-7-GHz (FR1) and mmWave (FR2) spectrum.
Keysight’s Protocol R&D Toolset is a comprehensive suite of tools for protocol and application testing of chipsets and devices. It covers the whole chipset and device development workflow from early prototype testing through to integration and verification. The R&D toolset enables users to test the latest available 5G features, including beamforming, multiple numerologies and subcarrier spacing. Users can efficiently test Layer 2 before the entire stack is completely implemented by using L2 Mode to carry out protocol testing for Layer 2 separately, which means issues can be found and resolved earlier in the design lifecycle leading to reduced R&D costs.
In more than ten years of collaboration, Keysight and Samsung have achieved several joint milestones, including the validation of dynamic spectrum sharing (DSS) technology used in 5G modems.
DSS allows mobile operators to quickly and cost-effectively roll out 5G NR services by implementing a software upgrade on existing 4G LTE base stations to create hybrid 4G/5G base stations. This emerging technology supports flexible use of existing spectrum allocations across low-, mid- and high- frequency bands by dynamically switching between LTE and 5G NR coverage based on traffic demand. Mobile operators’ deployment of DSS in their networks will accelerate deployment of 5G services and support global sale
