Samsung Using Keysight to Validate Dynamic Spectrum Sharing Tech in its 5G Modem

Keysight has announced a partnership with Samsung Electronics’ global semiconductor components and 5G technology division, System LSI, to validate dynamic spectrum sharing (DSS) technology used in the smartphone maker’s new 5G modem. Samsung used Keysight’s 5G network emulation solutions to accelerate the development of its RF solution, Exynos RF 5510, as well as its newest 5G modem, Exynos Modem 5123, which supports DSS technology.

DSS (Dynamic Spectrum Sharing) allows mobile operators to quickly and cost-effectively roll out 5G new radio (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 sales of 5G smartphones predicted to reach 1 billion by 2025, according to Strategy Analytics.

Widely adopted by mobile operators, chipset and device manufacturers, as well as test labs, Keysight’s 5G solutions are well-positioned to address a worldwide 5G smartphone market. Keysight’s 5G network test solutions allow users to cost-effectively validate multi-radio access technology (RAT) designs on a single platform for both non-standalone (NSA) and standalone (SA) mode in sub-6 GHz (FR1) and mmWave (FR2) frequency bands.
