As a preferred vendor, VIAVI has worked closely with the operator since early 2018 to test the performance and capability of next-generation infrastructure to further the commercial adoption of 5G technology.
During R&D test of wireless network equipment in the 5G Phase I project launched by China Mobile recently, VIAVI supported China Mobile Research Institute (CMRI) in validating 5G base station performance using the VIAVI TM500 Network Tester. The TM500 is used by network equipment manufacturers and service providers worldwide for testing complicated lab cases, including 5G multi-UE peak throughput testing, up to UL 8 layers and DL 16 layers.
In addition, VIAVI is collaborating with China Mobile to support development of Slicing Packet Network (SPN) with FlexE interface technology for 5G transport networks. Since 2018, VIAVI has developed SPN features in the ONT-600 QFlex Module based on China Mobile specifications as proposed for standardization by the ITU-T. At the recent OptiNet China Conference, the ONT-600 QFLEX Module was used by China Mobile in a 5G multi-vendor bearing network interoperability test, fully demonstrating the technical advantages of SPN technology for high bandwidth, low latency, ultra-high precision synchronization, flexible management and control.
The VIAVI Lab To Field portfolio which includes TM500 Network Tester, TeraVM 5G Core Emulator, CellAdvisor 5G Base Station Analyzer and NITRO Mobile and NITRO GEO, enables complete 5G lifecycle testing, said the Company.
