Open RAN (O-RAN)
Open RAN Overview
Open RAN is a recent trend in the telecommunications market (especially in the 5G area), aiming at the realization of the following key objectives:
- splitting of a base station into several functional components, including central unit (CU), distributed unit (DU), and a remote unit (RU);
- opening interfaces to enable interoperability (especially Open Fronthaul);
- disaggregating software from hardware in the RAN domain;
- introducing advanced automation into the RAN system by means of an abstracted entity to manage the radio networks, i.e. RAN Intelligent Controller (RIC) which serves as a platform for xApps (optimization applications in the RAN domain) and rApps (optimization applications in the management plane) using AI/ML.
Rimedo Labs contribute to the Open RAN topic in the following ways:
- xApp/rApp developments (RRM/SON algorithms design) – contact us to learn more;
- live and pre-recorded training delivery – see the agenda of O-RAN System Training here;
- active contribution to SD-RAN project as an ONF Member – read more here: Rimedo Labs joins ONF;
- delivering free and paid webinars – watch some on our youtube channel;
- content production in the form of blogs and whitepapers.
Below you can find out about our services and technical content related to Open RAN, which you can read, watch and download.
Note: you may find various terms related to Open RAN in the literature. „Open RAN” is used to refer to the overall movement of opening up the RAN by disaggregating hardware and software and creating open interfaces between them. The term „OpenRAN” is used by Telecom Infra Project. „O-RAN” with a hyphen is used by the O-RAN Alliance. „ORAN” is typically just used as a hashtag.
O-RAN Services
Our services in the Open RAN area include:
