5G means more network capacity and more network capacity means operators need more spectrum. While regulators around the world are working to open up frequencies for commercial mobile services, demand, as usual, is outpacing availability. To help bridge this gap, operators are looking to dynamic spectrum sharing (DSS), which will allow them to deploy LTE and 5G NR in the same band at the same time through a software update.
From the vendor side, all of the Ericsson Radio System gear sold since 2015 can support the software upgrade needed for DSS.
