A telecommunication network associated with a wireless telecommunication provider can be configured to select RAN components for use by a UE in an open RAN. Hardware/software of a telecommunication network automatically selects one or more RUs, DUs, and CUs (which may come from different vendors) to use for a communication session with a UE. In some configurations, an application on the UE specifies the desired performance (e.g., bandwidth requirements, processing requirements, latency requirements, . . . ). For example, if an application requests a large throughput of data, a Massive MIMO RU can be selected for use, whereas if a moderate throughput is specified, then a traditional 4×4 antenna can be selected for the communication session. Similarly, if the network load is high, then multiple DUs can be activated by the telecommunication network to work together and provide necessary processing power.
