Assessment of Open Ran: Difference between revisions

Radio Access Network (RAN) is a telecommunications network component that links your mobile phone or laptop to the core network<ref name=":1">https://www.ifri.org/sites/default/files/atoms/files/velliet_open_ran_2022_us.pdf</ref>. It comprises radio units (RUs), antenna and baseband units (BBUs) in the case of a 4G network. The BBU consists of centralized units (CUs) and distributed units (DUs). The RUs are responsible for sending and receiving data, whereas the BBUs process that data. In a traditional RAN architecture, the interface between the BBU and the RU is closed while all other interfaces are open. The Open RAN architecture aims to solve this, as shown by the French Institute of International Relations (Ifri) figures below.
