As operators look to scale out 5G coverage in tandem with the availability of more and lower-priced handsets in 2020, dynamic spectrum sharing (DSS) is a key feature. DSS allows LTE and 5G New Radio (NR) transmission in the same band at the same time. This lets operators avoid the time and expense associated with re-farming spectrum.
In the U.S., AT&T and Verizon have both discussed the role DSS will play in enabling an expansion of 5G from millimeter wave frequencies into lower bands, 850 MHz in AT&T’s case.
