O-RAN plugfests show 4G and 5G field tests
The plugfests were organised by leading communications service providers (CSPs) and the O-RAN Alliance with a series of on-site demonstrations in multiple countries.
In a multi-vendor based O-RAN environment, ensuring interoperability will become the network operator’s principal concern. Test equipment provider Viavi was involved in the plugfests with its Test Suite for O-RAN Specifications to validate that all interfaces are working correctly, including the RF, signaling and interoperability, timing and synchronisation.
The plugfest in Berlin, Germany, was hosted by Deutsche Telekom, with demonstrations of radio access equipment from Baicells, Benetel, Foxconn, QCT, Wind River, Wiwynn and other vendors. Viavi provided its TM500 including UE emulation for performance testing and O-DU emulation for O-RU subsystem testing; TeraVM for core emulation and traffic generation; MTS-5800 for transport and synchronization test; and CellAdvisor 5G for RF signal analysis.
In a plugfest in Torino, Italy, hosted by TIM, VIAVI provided the MTS-5800 for timing and synchronization in demonstrations of radio access equipment from Commscope, WNC, Wiwynn and other vendors.
在西班牙马德里，O-Ran X-Haul（Fronthaul和Midhaul）的运输，来自多个供应商的设备使用MTS-5800进行计时和同步，以及ONT-800进行多端口运输测试。
Airtel’s plugfest in Bengaluru, India, used radio access software and equipment from Altiostar, NEC, VVDN and Xilinx with the TM500-C-5G 5G NR UE emulator and TM500 O-RU emulator for detailed verification of the O-DU’s compliance to the WG4 open fronthaul (C/U/S planes) specification.
总共34家公司参加了欧洲插件的欧洲分支机构。以EANTC为系统集成商，在Highstreet Technologies和托管运营商的工程师的支持下，有：Altran，Astri，Baicells，Baicells，Benetel，Calnex，Ciena，Ciena，Cisco，Cisco，Conscope，Commscope，Delta，Exfo，Exfo，Exfo，Foxconn，Foxconn，JMA无线网络，JMA无线网络，JMA无线网络，夹头夹具网络，Keysight Technologies，Mavenir，MTI Mobile，NG4T，QCT，Radisys，Rohde＆Schwarz，Viavi Solutions，Wind River，Wiwynn，WNC和Xilinx。
“ O-Ran和Tip Plugfest联合展示了社区加速多供应商O-RAN符合网络基础架构的准备。这是第一次欧洲的运营商联手欢迎生态系统合作伙伴，并促进了对其分类的汇编组件的验证，集成和测试。电信。“这项协调的欧洲社区努力代表了实现多供应商O-Ran符合O-Ran产品的强大生态系统的又一步。”
“As a champion of interoperability test methodologies, and the first company to introduce a comprehensive test suite for O-RAN specifications, VIAVI has worked closely with ecosystem partners and operators worldwide to help identify, isolate and resolve performance issues with disaggregated networks,” said Sameh Yamany, Chief Technology Officer at Viavi. “The successful results of the global O-RAN ALLIANCE plugfest represent a significant step forward in the advancement of multi-vendor O-RAN environments, which are essential to scaling and sustaining 5G networks.”
在实验室中，TM500和TERAVM家族提供UE，O-RAN子系统和核心网络模拟，以实现完整基础站和核心网络测试的一致性，互操作性和性能测试，以及对单个O-RAN子系统和核心的环绕测试网络元素。在实验室和字段中，T-Berd/MTS-5800都使用其定时扩展模块（TEM）验证了必要的精度，验证了关键同步参数，为同步测试设备和O-RAN组件提供了高度稳定的参考信号。蜂窝visor 5G表征和分析4G和5G RF信号。ONT-800测试运输网络性能高达800克。
