NED File simulations/nr/networks/MultiCell_Standalone.ned

Name	Type	Description
MultiCell_Standalone	network	Two gNodeB cells served by a 5G core: the anchor Upf faces the data network (a router and a server), an intermediate Upf feeds both gNodeBs, and an X2 link joins them. numUe NrUe terminals attach, and numBgCells BackgroundCell cells can be added as interferers.
