O-DU (O-RAN Distributed Unit) is a component of the O-RAN (Open Radio Access Network) architecture. O-RAN is an open, intelligent, and flexible radio access network architecture that aims to improve the performance and efficiency of wireless networks while also reducing costs and complexity.
O-DUs are responsible for performing radio access functions such as modulation, demodulation, and decoding/encoding of data. They are designed to be distributed across the network and to work in collaboration with other O-RAN components, such as the O-RU (Radio Unit) and the O-CU (Central Unit).
Overall, the use of O-DUs in O-RAN architectures is intended to enable more efficient and
cost-effective deployment of wireless networks, and to provide a more flexible and scalable solution for meeting the growing demand for high-quality wireless connectivity.
