What are the 5G signal levels and what should be the optimal values?
- The “Non-Stand Alone” (NSA) architecture, where the 5G Radio Access Network (AN) and its New Radio (NR) interface is used in conjunction with the existing LTE and EPC infrastructure Core Network (respectively 4G Radio and 4G Core), thus making the NR technology available without network replacement. In this configuration, only the 4G services are supported, but enjoying the capacities offered by the 5G New Radio (lower latency, etc). The NSA is also known as “E-UTRA-NR Dual Connectivity (EN-DC)” or “Architecture Option 3”.
- The “Stand-Alone” (SA) architecture, where the NR is connected to the 5G.
- Only in this configuration, the full set of 5G Phase 1 services are supported.
