What is 5G NR dual connectivity?

Dynamic spectrum access is the process of increasing spectrum efficiency via the real-time adjustment of radio resources , such as via a process of local spectrum sensing, probing, and the autonomous establishment of local wireless connections among cognitive nodes and networks.

5G NR Dual Connectivity (DC) is a feature that allows mobile devices to utilize both mid-band and mmWave frequencies (LTE and FR2) to provide improved network coverage and data rate .

The technology enables sharing of a spectrum channel, dynamically allocating resources to either New Radio (NR) or LTE technology based on usage . Verizon says it has DSS deployed in 2,700 cities for 5G Nationwide coverage.

Dynamic Spectrum Sharing (DSS for short) is a new antenna technology that for the first time enables the parallel use of LTE and 5G in the same frequency band . The technology determines the demand for 5G and LTE in real-time.
