Open RAN

A movement in the wireless industry that advocates  for hardware and software disaggregation, openness, and  interoperability in RAN architectures, and acts towards the  standardization of open interfaces to allow multi-vendor RAN  environments. Open RAN is also a RAN reference architecture  that leverages industry-wide standards, defined by organizations  such as the O-RAN Alliance, 3GPP, IEEE, and others, to support  the interoperability between different software and hardware  vendors. It is particularly important for C-RAN architectures,  and heavily accelerated by RAN virtualization, given the  disaggregation and multiplication of vendors that come with it.
