Nokia said that it will launch Dynamic Spectrum Sharing (DSS) solution in 2020.
Harri Holma who is is one of Fellows with Nokia Bell Labs. wrote in a blog that, "Dynamic Spectrum Sharing (DSS) enables mobile operators to dynamically share spectrum resources across different technologies. Depending on an operator’s spectrum assets, it’s an important function that can enable the faster introduction of new 5G services. It can also be used across all Radio Access Types to manage the transition period around the uptake of new services as well as the decline of a legacy technology."
Hea added that, "Nokia is the only vendor that already supports different variants of dynamic sharing between 2G, 3G and 4G, and is the de-facto technology leader in commercial 2G, 3G and 4G dynamic sharing implementations. DSS between 4G and 5G will become an important technology with the introduction of 5G to the Frequency Division Duplex (FDD) bands. The first 5G FDD network was launched in the U.S in December 2019 and is powered by Nokia. 5G FDD devices supporting DSS will become available during 2020. Nokia will introduce DSS as a software upgrade in line with commercial 5G FDD mass market device availability in 2020 and is excited about the benefits it will bring to its customers deploying 5G."
