Further alignment of the O-RAN ALLIANCE and Telecom Infrastructure Project (TIP)

On October 25, 2022 during the Open RAN Summit at Fyuz in Madrid, O-RAN and TIP announced a further alignment of their value propositions and deliverables to complement each other seamlessly.

TIP references O-RAN technical and test specifications and TIP members help to improve them through the change request process. O-RAN and TIP mutually recognize test results performed in the O-RAN-approved Open Testing and Integration Centers (OTIC) and TIP Community labs.

Alignment between O-RAN and TIP enables the ecosystem to streamline the development of O-RAN based products, verify interfaces and interoperability of components, and demonstrate the functionality and operational performance of the open RAN solutions that are commercially available.


The O-RAN ALLIANCE is a world-wide community of more than 330 mobile operators, vendors, and research & academic institutions operating in the Radio Access Network (RAN) industry. As the RAN is an essential part of any mobile network, the O-RAN ALLIANCE’s mission is to re-shape the industry towards more intelligent, open, virtualized and fully interoperable mobile networks. The new O-RAN specifications enable a more competitive and vibrant RAN supplier ecosystem with faster innovation to improve user experience. O-RAN based mobile networks at the same time improve the efficiency of RAN deployments as well as operations by the mobile operators. To achieve this, the O-RAN ALLIANCE publishes new RAN specifications, releases open software for the RAN, and supports its members in integration and testing of their implementations.
