Research on 5G multiband networking and optimization strategy

Abstract： With the continuous development of mobile communication network, operators have different frequency band resources at high, middle and low levels. Radio frequency band resources are valuable strategic resources, and how to use spectrum resources reasonably and efficiently is the primary issue that operators consider at present. Based on the comparative analysis of the coverage performance and service bearing of 5G NR 2.1 GHz and NR 3.5 GHz bands, this paper puts forward suggestions for networking and inter-carrier mobile strategy in different scenarios, providing an important basis for the subsequent construction of 5G networks.
