O-RAN Global PlugFest Fall 2023 at i14y Lab

The i14y Lab consortium invites all vendors of Open RAN-related solutions and platforms to the upcoming O-RAN Global Plugfest Fall 2023. The testing in Berlin will be closely aligned with other European PlugFest hosts, and with Telecom Infra Project (TIP) activities.


During the event, participating vendors will get the opportunity to validate the technical readiness of their individual solutions, explore multi-vendor interoperability in new or refined test scenarios, and prepare test results for public reporting. The tests will be based on O-RAN Alliance specifications and TIP test plans customized for this session. We will take technical priorities provided by the OpenRAN MoU Group of European service providers into account as well.


All tests will be executed in a vendor-neutral environment with multiple test tools and partially automated test execution. The specific list of applicable tests and low-level steps will be selected together with interested participants in preparation for the PlugFest.

  • Near-RT or non-RT RIC
  • SMO, xApps, rApps
  • Test and measurement equipment

Our high-level test scope is:

  • Verification of O-RAN-based O-RU, O-DU/O-CU implementations for Open Fronthaul functions and performance
  • Testing of multi-vendor O-RAN-based end-to-end solutions (including products and solutions aligned with TIP requirements documents):
    • Systems under test: O-RU + O-DU + O-CU
    • Optionally including Near-RT RIC with xApps
    • Optionally including Non-RT RIC with rApps
    • Optionally including NETCONF-based SMO solutions with standards-based Yang models
    • Including indoor disaggregated small-cell systems using TIP-specified end-to-end test plans
  • Evaluation of network optimization use case scenarios
    • Near-RT and non-RT RICs implementing A1/E2 interfaces
    •  xApps and non-RT RIC rApps in standalone emulation scenarios

New or improved test cases that are developed as part of this event will be upstreamed to the respective SDO.

„Terms and Conditions“

Participants are asked to

  • Attend planning calls and preparational activities
  • Provide system under test hardware (if applicable) and/or software for the full pre-staging and testing time
  • Provide (remote) installation and configuration support during prestaging
  • Actively participate in testing (on-site, if possible, at least with a partial team) and provide experienced engineering support for troubleshooting during at least two full 2  weeks of the main Plugfest time
  • Share full results for all test cases executed with the Plugfest organizers
