Sharing of the active network has long been shunned by operators, fearing loss of control and differentiation, but the economics of a saturating market are driving some MNOs to take a kinder view. And emerging technologies, especially in the virtualized RAN and 5G core, will make it easier for operators to maintain full control of their network experience on common infrastructure. Before those standards mature, however, rising numbers of MNOs, especially in Europe, are sharing their RANs using existing mechanisms. A new example is that of Telenor and Telia in Denmark, which are working to roll out a shared 5G network based on Nokia equipment, using the 3GPP MOCN (multi-operator core network) approach. This allows for each MNO to have…
