Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

Figure 4.2.2-1 shows the high-level view of the roaming 5G System architecture for Ranging based services and Sidelink Positioning with service-based interfaces within the Control Plane. In this figure, UE A use a subscription of the HPLMN.
