Viavi Solutions will provide hardware technologies to China Mobile to support the deployment of 5G services in China by the end of 2019.
Viavi supports China
Mobile’s specific technologies and aggressive
roadmap with advanced test solutions, making the company a
preferred vendor of the Chinese telco.
For the project, Viavi will provide test and measurement
hardware, as well as software to China Mobile and other
equipment manufacturers to support the development of Slicing
Packet Network (SPN) with FlexE interface that the technology
carrier is developing for 5G transport.
"Viavi has been honoured to collaborate with China Mobile on
analysing 5G network scenarios and proposing technology
strategy. In order to realize China Mobile’s
vision of introducing 5G service by the end of 2019, principal
technologies including SPN for transport must be standardized
by the ITU-T. We have advanced our test technology to meet this
objective, and our solutions are ready to support the China
Mobile ecosystem of partners to deliver interoperable network
infrastructure," said Oleg Khaykin, president and chief
executive officer of Viavi Solutions.
Through its analysis of 5G transport network requirements,
China Mobile has found that SPN is optimal technology to
support next-generation architecture, bandwidth, traffic model,
network slicing, latency and time synchronization. Flexible
Ethernet is used in conjunction with SPN to create smaller
Ethernet channels from a larger one, or vice versa, to
guarantee quality of service and isolation between slices at
the transport layer. In addition, China Mobile has
requested that the International Telecommunication Union
Viavi will continue to support China Mobile by delivering a
SPN test platform creating a common foundation for network
equipment manufacturers, chip developers and transceiver
vendors to validate products based on this technology.
In January of this year, Yang Zhiqiang, deputy general
manager of China Mobile Research Institute (CMRI) met with
Khaykin, Tom Fawcett, vice president and general manager of the
lab & production business unit, Viavi Solutions, to her
offices for strategic meetings on 5G planning prior to the
announcement. The CMRI is a technical organization within the
China Mobile group and is responsible for new technology
research, standardization, and qualification of infrastructure
equipment—including testing protocols.
Viavi launched CPRIAdvisor in June of last year,
it’s a remote radio frequency (RF) spectrum
monitoring system that addresses a wide range of antenna
deployment options in heterogeneous networks. The
monitoring system can support a macro cell with a smaller
number of fronthaul fibre links; a large centralized radio
access network (C-RAN) or distributed antenna system (DAS) with
hundreds of fronthaul links.
