Lesson plan
Open RAN
Open RAN, or Open Radio Access Network architecture is based on 3GPP standards for Radio Access Networks (RAN) but contains many extensions, disaggregates RAN components and makes their interfaces open, aiming to improve flexibility and interoperability. RAN hardware and software are cloudified/virtualized, and it includes intelligent management (SMO). Those open interfaces aim for mixing components from different vendors and quicker deployment of new services. Open RAN standardization is led by the O-RAN ALLIANCE. Cloudification means disaggregating hardware and software, making RAN software cloud-native functions running on a general-purpose hardware. Intelligent open management includes automated management and orchestration systems which can utilize Artificial Intelligence and Machine Learning for life cycle management of network functions. Open interfaces: standardized open interfaces, such as the O-RAN ALLIANCE's specifications and 3GPP-defined interfaces, facilitate interoperability between disaggregated RAN components.
