Verizon has successfully tested Dynamic Spectrum Sharing (DSS) technology in a "live network environment" in both Texas and Minnesota. DSS is a key element of Verizon's unique 5G deployment strategy. So far, Verizon's 5G network has been limited to mmWave frequency bands, which offer high speeds but very limited coverage (typically only the densest parts of downtown areas in major cities, and venues such as arenas and stadiums.) While other major US carriers have already deployed 5G in existing, lower frequency bands for broad 5G coverage, Verizon is waiting until DSS technology is ready. DSS allows carriers to deploy 5G in existing frequency bands much more efficiently, ensuring 4G network capacity is not reduced unnecessarily. DSS allocates radio frequencies between 4G and 5G in real time, based on demand at each moment. Earlier this month, AT&T announced it has started deploying DSS.
