Ericsson’s DSS is available, ZTE’s implementation covers legacy bands too

Dynamic spectrum sharing (DSS) is an important 3GPP-standardized technology which will greatly improve operators’ spectrum efficiency as they deploy 5G to augment their existing 4G networks. It allows the 5G and 4G radios to share the 4G spectrum flexibly, opening up new bands for the newer technology, and allowing the balance of traffic to be shifted between the two networks according to usage. However, DSS is hard to implement and requires very high performance baseband processing. All the major vendors have been working on it, but Ericsson has been most successful in published live trials, and is now the first to claim general availability. This will be particularly important to Verizon, which has committed to deploying DSS throughout its network…
