Open RAN Technical Priority Document, by the Open RAN MoU signatories (Deutsche Telekom, Orange, Telefónica, TIM and Vodafone) – June 2021

The “Open RAN Technical Priorities Document” is the result of the work carried out under the MoU on Open RAN signed by Deutsche Telekom AG, Orange S.A., Telefónica S.A., TIM and Vodafone Group Plc. This document offers a comprehensive list of technical requirements that the signatories of the Open RAN MoU consider priorities for Open RAN architecture to guide and foster a competitive open RAN ecosystem, promoting openness and flexibility. It includes the main scenarios and radio configurations targeted for operators’ deployment, providing hardware and software requirements for each of the building blocks of a disaggregated RAN. The overall system relies on open interfaces to allow multi-vendor deployment in a fully interoperable manner, and intelligent radio controllers and orchestration in a cloud-native environment to unleash the potential of a fully automated network. The overall objective is to promote a fast pace for the development of open, virtualized and programmable RAN solutions, and support a timely roll-out of open RAN networks in Europe.

The document is available on both the O-RAN Alliance and TIP websites:
