5G Network Evolution and Dual-mode 5G Base Station

The fifth generation (5G) networks can provide lower latency, higher capacity and will be commercialized on a large scale worldwide. In order to efficiently deploy 5G networks on the basis of the existing Long Term Evolution (LTE) networks, dual-mode 5G base station is a potential technology which can support Non-standalone (NSA) and Standalone (SA) network access. This paper focuses on the principles of the dual-mode 5G base station based on a comprehensive review of the 5G network architecture and evolution. Combined with the field trial data, the performance of the dual-mode 5G base station was analyzed. Finally, some practical suggestions on the deployment of dual-mode 5G base stations for operators are proposed.
