The O-RAN ALLIANCE is a world-wide community of more than 300 operators, vendors and research and academic institutions working in a transparent way to develop a sustainable open RAN ecosystem . 30 mobile network operators committed to O-RAN are serving over 4.5 Billion subscribers around the world.

O-RAN Global PlugFest 2021 – O-RAN’s third world-wide testing and integration event – demonstrated the strength of the O-RAN ecosystem and its global drive towards open and intelligent Radio Access Networks (RAN). The O-RAN PlugFest expanded from 4 to 7 global venues, with 94 participating companies. Many of the companies contributed to multiple venues, bringing PlugFest to a total of 144 active corporate participants compared to 70 at the 2020 PlugFest.

“The expanded and diverse participation of companies from across the technology ecosystem at the O-RAN Global PlugFest 2021 is testimony to growing momentum behind Open RAN and its relevance for our industry,” said Alex Jinsung Choi, Chief Operating Officer of the O-RAN ALLIANCE and SVP of Strategy and Technology Innovation, Deutsche Telekom. “The joint, open and coordinated O-RAN Global PlugFest framework is crucial for all O-RAN members to collaborate within the community and accelerate the ecosystem development of commercially available Open RAN solutions.”

Testing multi-vendor interoperability, Radio Intelligent Controllers, O-Cloud, infrastructure security and end-to-end functionality

Overall, O-RAN Global PlugFests bring a great opportunity for the industry to deal with integration challenges in an efficient way and to make major progress in development of commercial O-RAN products. This year’s PlugFest was not an exception, as demonstrated by the successes:

• This year’s PlugFest proved advanced maturity of the Open Fronthaul (OFH) implementations. Interoperability has been achieved between many vendors in different network setups, base station classes, OFH profiles and RU/CU-DU product combinations.
• There were several demonstrations of advanced use cases utilizing the O-RAN Near-Real-Time Radio Intelligent Controller (Near-RT RIC) and Non-Real-Time RIC (Non-RT RIC), like automated network outage detection and recovery, and latency assurance for end-to-end network slicing. A lot of effort also went into testing individual RIC interfaces, application protocols, and related xApps and rApps.
• Several venues successfully tested O-Cloud products and multi-vendor virtualized RAN integrations.
• Specific tests dealt with the O-RAN infrastructure security.
• Thanks to the O-RAN community enthusiasm and great collaboration, several O-RAN end-to-end functionality tests passed against production core network elements, while many others utilized simulators.
• All venues proved the readiness of advanced test equipment and simulation of different parts of the network.
• PlugFest hosts managed combinations of on-site and remote testing, reflecting the Covid-19 pandemic situation in different parts of the world.

In Asia, the O-RAN Global PlugFest 2021 took place at four venues

Another stream focused on 3GPP RF Conformance testing and demonstration of autonomous RAN outage detection and self-healing utilizing O-RAN Non-Real-Time and Near-Real-Time Radio Intelligent Controllers (Non-RT and Near-RT RIC). Near-RT RIC concept and the detailed mechanisms were also showcased to support latency assurance for end-to-end network slicing. Potential parameters to be supported in the O-RAN specifications were identified as study results.

As a complementing activity, selected participants started a study on RAN emission characteristics.

In addition to the hosts, participants included Fujitsu, HCL, JMA Wireless, Keysight Technologies, NEC, Nokia, NVIDIA, Samsung, VIAVI Solutions and Wind River .

The O-RAN PlugFest in Republic of Korea was hosted by LG Uplus for the first time in Korea at its 5G Innovation Lab in LG Science Park, Seoul. The primary focus was on evaluation of Open Fronthaul for multi-vendor interoperability of a 5G SA system (FR1, TDD).
