Type of Dual Connectivity

Home                 LTE                NB-IoT            5G(NR-NSA) Today, we will learn about different type of Dual Connectivity between NR and LTE. If you are interested in learning more about 5G please  click here . What is MR-DC? MR-DC stands for Multi-Radio Dual Connectivity. UEs which support multiple Tx/Rx can be configured to utilize resources from two different nodes. One of these nodes could provide NR access and the other one could provide either E-UTRA or NR access. One node will act as the Master Node (MN) and the other as the Secondary Node (SN). MR-DC with the EPC (legacy LTE Core): Legacy LTE (E-UTRAN) supports MR-DC through EN-DC (E-UTRA-NR Dual Connectivity). 1)  EN-DC DUT (device) shall connect to one eNB that is acting as a master-node (MN) and one en-gNB acting as a secondary-node (SN). The master-nod...

5G Deployment scenarios

Home                 LTE                NB-IoT            5G(NR-NSA) Today, we will learn about Dual Connectivity between NR and LTE. If you are interested in learning more deployment options, click here . The radio access networks based on the New Radio (NR) standard will provide high levels of capacity and peak data rates along with low latency. It is estimated that these networks can provide tens of megabits of data per second to tens of thousands of users at the same time.  Telecom operators have the opportunity to demonstrate leadership in technology and performance by meeting growing demands of mobile traffic profitably. This can be done by delivering new levels of cost-efficiency (including spectrum efficiency and sharing current assets), digitalization and new revenue streams. The 5G standards were introduced by 3GPP in Release 15 to provide g...
