Providing omnipresent 5G cellular connectivity is very appealing to advance a wide range of use cases and industry verticals. However, it is expected that the commercial rollout of5G networks will be progressive starting from 5G radio access network (RAN) integrated with existing 4G cores, i.e., non-standalone (NSA), to the full 5G architecture with both 5G RAN and 5G core, i.e standalone (SA). Hence, it is of utmost importance to evaluate and compares the performance of these SA and NSA networks so as to examine if the requirements of 5G-reliant use cases can be met. In this regard, this paper conducts preliminary field trials for SA and NSA 5G networks based on a self-contained5G base station. The performance of both networks is compared under different system setups and key performance indicator (KPIs) such as data rate and latency are measured. Preliminary results reveal that the achievable uplink rate from SA 5G networks slightly outperforms that of the NSA counterpart under the sameRAN setup. Moreover, the network latency of both networks are shown to be comparable.
