What’s Open RAN? | |||
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. | |||
As shown in figure 2, the Open Ran architecture disaggregates the BBU into DU and CU using the 3rd Generation Partnership Project (3GPP) standards and creates open interfaces between them. The open interfaces enable the operator to incorporate many vendors into its network, as we will discuss further in this report. However, it should be noted that this is not the only work of the Open Ran architecture. With Open Ran deployment, the operator benefits from its many other features. | As shown in figure 2, the Open Ran architecture disaggregates the BBU into DU and CU using the 3rd Generation Partnership Project (3GPP) standards and creates open interfaces between them.
