With the global 5G network rollout, dynamic spectrum sharing (DSS) between 4G and 5G is a focal point for mobile network operators. DSS enables the quick and cost-effective build out of robust 5G services, with broad coverage areas, using existing spectrum in mid- and low-band frequencies. Keysight can help you test the DSS capability of your base stations to ensure the simultaneous transmission of LTE and 5G New Radio (NR) services in the same 4G band.

DSS Functional and Performance Verification 

DSS functional and performance verification is critical to enabling DSS to have significant impact on mobile network performance. DSS performance may vary by network vendor because 3GPP specifications allow a great deal of freedom on DSS implementation, leaving room for differentiation among different vendors. The proprietary implementation of the base station packet scheduler at the heat of DSS functionality can also vary by infrastructure vendor. End-to-end testing in this context means testing the complete network with real devices in the exact configuration as end users both in the lab and in the field.
