Keysight and Qualcomm eye Dynamic Spectrum Sharing

Keysight Technologies announced an extended collaboration with Qualcomm to accelerate commercialization of Dynamic Spectrum Sharing (DSS) technology.

DSS enables a mobile operator to flexibly use 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 can leverage DSS to deliver the best possible performance and coverage for a mix of 4G and 5G devices.

The collaboration utilizes Keysight’s 5G network emulation solutions to accelerate the development of Qualcomm Snapdragon 5G Modem-RF System to support DSS, an emerging technology that is part of the 3GPP Release 15. By 2020, mobile operators are expected to start implementing DSS on existing 4G LTE base stations, speeding nationwide deployments of 5G services. DSS allows mobile operators to transform LTE base stations via a software upgrade to create hybrid 4G/5G base stations. As a result, users of DSS-capable 5G NR devices can access 5G services in urban and rural environments.

“Our continued collaboration with Keysight on 5G technology, which was initiated in 2015, has enabled Qualcomm Technologies to accelerate the implementation of DSS, a critical feature that will help mobile operators quickly transition to 5G,” said Jon Detra, vice president, engineering, Qualcomm Technologies, Inc. “Keysight helps us develop and validate our Snapdragon 5G Modem-RF System designs at a pace that will help accelerate 5G commercialization.”
