And also OpenRAN: “The OpenRAN Project Group is an initiative to define and build 2G, 3G, 4G, and 5G RAN solutions based on general-purpose vendor-neutral hardware, open interfaces and software.”
Also, for those that are new to the "RAN" terminology (as I was just a few minutes ago! <g>):
A RAN is mini-WAN?
But No in term of type: RAN is a functional part of operator operational network and therefore not as function and traffic neutral as a WAN is.
