- Keysight Technologies announced an extended collaboration with Samsung Electronics’ LSI Business, a provider in semiconductor components and 5G technology, to validate dynamic spectrum sharing (DSS) technology used in the smartphone maker’s new 5G modem.
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.
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 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.
“We’re excited to once again showcase our 5G technology leadership by being the first test vendor to successfully validate the DSS feature on Samsung’s new Exynos modem,” said Kailash Narayanan, president and general manager of Keysight’s wireless test group.
