Method and transition device for enabling communication of data in a wireless network

A transition device enabling communication of data in a wireless network between a remote radio unit and a central baseband unit, the transition device comprising:

• one or more processors that:
• configure one or more interface functions based on both a first interface configuration of the remote radio unit and a second interface configuration of the central baseband unit, the one or more interface functions being selected from a set of predefined interface functions associated with different interface configurations;
• establish at least one data flow between the remote radio unit and the central baseband unit over the transition device;
• and
• perform conversion between the first interface configuration and the second interface configuration for data communicated in the at least one data flow, using the selected one or more interface functions, wherein
• the one or more processors perform conversion by converting between the first interface configuration and an intermediate interface configuration adapted for a switching function;
• the one or more processors perform conversion by converting between the intermediate interface configuration and the second interface configuration, and
• the one or more processors transport the data through the switching function using the intermediate interface configuration.
