Keysight Technologies announced an extended collaboration with Samsung Electronics' LSI Business, a producer of semiconductor components and 5G technology, to validate dynamic spectrum sharing (DSS) technology used in the smartphone maker's new 5G modem.

DSS allows mobile operators to 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 technology supports flexible use of existing spectrum allocations across low-, mid-, and high- frequency bands by switching between LTE and 5G NR coverage based on traffic demand.

Samsung has used Keysight's 5G network emulation solutions to accelerate the development of its radio frequency (RF) solution, Exynos RF 5510, as well as its newest 5G modem, Exynos Modem 5123, which supports DSS technology.

Widely adopted by mobile operators, chipset, and device manufacturers, as well as test labs, Keysight's 5G solutions are positioned to address a worldwide 5G smartphone market, according to the company.
