Keysight Technologies collaborated with 14 industry partners to demonstrate Open RAN deployment readiness testing at the O-RAN Spring 2023 Global PlugFest organized by the O-RAN ALLIANCE.
During PlugFest, Keysight Open RAN Architect (KORA) solutions were used with Keysight co-developed O-RAN test specifications across these focus areas:
- Open RAN Radio Unit (O-RU) Fronthaul Conformance / Performance – Conducted automated testing of O-RU compliance to WG4 fronthaul technical specifications using the Keysight O-RU test suite, including control, user, synchronization and management (CUSM) planes and performance across the radio frequency (RF) and protocol measurements domains. Test collaborators included Compal, ETRI, Inventec, Pegatron, and SOLiD.
- RAN Intelligent Controller (RIC) Conformance – Used the cloud-native Keysight RIC Test Suite to test and validate near-real-time RIC and non-real-time RIC compliance to the WG2 A1, WG3 E2, and O1 technical specifications by emulating E2 nodes, near-real-time RIC, and user equipment (UE). Test collaborators included Compal, ITRI, LITEON, and Pegatron.
- End-to-End (E2E) Network Performance – Provided E2E testing and assessment of small cells, macro cells, and gNodeBs (gNB) for performance, security, latency under, load and stress test conditions using the Keysight E2E test suite. An over-the-air (OTA) monitor was used to extend real-time visibility to disaggregated radio access, correlation, and interaction between O-RAN protocol and 3GPP physical layers in wireless transmissions. Test collaborators included Askey, Compal, LIONS Technology, Pegatron, SageRAN, SOLiD, and Quanta Cloud Technology (QCT).
- 5G and O-RAN Security – Validated the design and implementation of security for O-RAN gNBs with simultaneous operations of emulated UEs and security attack modules (3GPP SCAS automated testing, DDoS, Fuzzing) using the Keysight 5G and O-RAN security test suite. Tests ensured that the experience of emulated subscribers and network performance were not adversely impacted during simulated attacks. Test collaborators included LITEON and Pegatron.
