The disintermediated nature of open virtualized radio access networks (Open vRANs) is the key to the flexibility, cost savings and innovation that have made it a part of the plan for many mobile network operators (MNOs) that are expanding a 4G network or embarking on a new 5G network.
Some people have suggested this multivendor approach is creating a systems integration burden for MNOs. But in reality, the concept of system integration has always been a part of RAN networks. With a legacy network, it came bundled into the whole solution. But it was never performed solely by one vendor.
