Second is the virtualization of the core and RAN, potentially with open architectures such as O-RAN, which will take off most quickly in the largely greenfield cellular market of the enterprise. And third is the emergence of new deployers of enterprise networks, in scenarios that do not make commercial sense for MNOs, but where there is real demand for 4G/5G capabilities. Private network operators are coming out of their old niches in high value, but low volume, proprietary networks such…
