Radio Access Networks (RANs) have been controlled by proprietary network equipment from the same vendor or group of vendors for the majority of cellular communications history. Single-vendor RANs may have provided certain benefits as the wireless communications industry matured, that time has long passed.
Being locked into a proprietary RAN has placed mobile network operators (MNOs) at the mercy of network equipment makers, creating a bottleneck for innovation. Open RAN enables mobile network operators to use equipment from multiple vendors and still ensure interoperability.
Open RAN disaggregated RAN functionality by using open interface specifications and community developed standards between elements of the RAN; this means each piece of hardware and software can be separated and replaced by hardware or software from various vendors.
