Nokia and ADVA demo end-to-end 5G synchronization

ADVA and Nokia jointly demonstrated end-to-end network timing with the accuracy and resilience needed for 5G services.

The demonstration, which was presented at Orange Poland’s Innovation Garden Summit, highlighted how precise phase and frequency synchronization can be delivered and assured from the core to the cell site without risk from GNSS vulnerabilities.

The live showcase in Warsaw featured ADVA’s diverse range of Oscilloquartz products. This includes ultra-compact small-form-factor solutions designed to be utilized in large numbers even in the most challenging and space-restrictive conditions.

ADVA said its solutions meet the urgent demand for precise timing at the network edge. At the other end of the scale are Oscilloquartz modular, high-performance IEEE 1588v2 PTP core grandmasters that provide ultimate scale with a carrier-class design and in-built hardware redundancy. As part of the OSA ePRTC system, these provide an ultra-precise source of time with guaranteed holdover performance, removing the risk of reliance on GNSS alone.

“Our joint demo with Nokia answers the most urgent timing challenges facing today’s network operators. It highlights how our solutions can accelerate the deployment of 5G, IoT and mobile edge computing by delivering new levels of accuracy and stability for phase and frequency synchronization,” said Jörg Urban, senior director, business development, Oscilloquartz, ADVA. “We’re showing Tier 1 CSPs how easy it is to distribute, monitor and assure end-to-end timing that is fully resistant to GNSS outages. The precision and reliability that our technology offers will empower operators to support emerging applications in fields such as highly interactive augmented reality and self-driving vehicles.”

The company said the technology provides the ideal timing source for mission-critical transport...


Radisys contributes seed code to the O-RAN Alliance

Radisys is contributing its Open 5G Software seed code to the O-RAN Alliance for its 5G NR Stack Reference Architecture thereby helping to accelerate the O-RAN ecosystem and enable the delivery of open APIs and open architectures for mobile operators.

Radisys, along with China Mobile and AT&T as the Operator co-chairs, is teamed with Intel to co-chair Work Group 8 to define the 5G NR stack reference architecture. Radisys is the first contributor to this effort with its seed code. The O-RAN Alliance’s additional workgroups will leverage the code for their own deliverables.

The Radisys’ Open 5G Software seed code was made available as open source code by the O-RAN Alliance’s Software Community during MWC Shanghai, which occurred June 26-28.

"We share a common vision with our WG8 co-chairs – China Mobile, AT&T and Intel – to accelerate RAN evolution through the principles of disaggregation and openness, while laying the groundwork for 5G networks that are being built today,” said Neeraj Patel, vice president and general manager, Software and Services, Radisys. “We thank our mobile operator co-chairs for welcoming us as co-chair, re-affirming our own commitment to the open telecom revolution, and we call on other vendors and operators to make their own contributions to this important work."

O-RAN Open Source Community gets underway

The O-RAN Alliance and the Linux Foundation have established the O-RAN Software Community (O-RAN SC) to provide open software aligned with the O-RAN Alliance’s open architecture.

As a new open source community under the Linux Foundation, the O-RAN SC is sponsored by the O-RAN Alliance, and together they will develop open source software enabling modular, open, intelligent, efficient, and agile disaggregated radio access networks. The initial set of software projects may include: near-real-time RAN intelligent controller (nRT RIC), non-real-time RAN intelligent controller (NRT RIC), cloudification and virtualization platforms, open central unit (O-CU), open distributed unit (O-DU), and a test and integration effort to provide a working reference implementation. Working with other adjacent open source networking communities, the O-RAN SC will enable collaborative development across the full operator network stack.

“This collaboration between the O-RAN Alliance and the Linux Foundation is a tremendous accomplishment that represents the culmination of years of thoughtful innovation around the next generation of networks,” said Andre Fuetsch, Chairman of the O-RAN Alliance, and President of AT&T Labs and Chief Technology Officer at AT&T. “The launch of the O-RAN SC marks the next phase of that innovation, where the benefits of disaggregated and software-centric platforms will move out to the edge of the network. This new open source community will be critical if 5G is to reach its full potential.”

China Mobile activates its first Access CDN at the OLT

China Mobile (Zhejiang) activated its first commercial Access CDN deployed at the OLT.

To address the problem of huge video traffic volume, Zhejiang Branch of China Mobile has adopted ZTE's innovative Light Cloud solution to push the CDN to the OLTs, which is the network node nearest to the users, by loading IT capabilities into the OLTs. The solution reduces access latency, increases download speeds, and enhances service experience. In addition, it saves upstream bandwidth by up to 60 percent, thereby alleviating upstream network bandwidth shortages.

Intel confirmed that it is collaborating with Baidu on development of the new Intel Nervana Neural Network Processor for Training (NNP-T). The collaboration involves the hardware and software designs of the new custom accelerator with one purpose – training deep learning models at lightning speed.

Since 2016, Intel has been optimizing Baidu’s PaddlePaddle deep learning framework for Intel® Xeon Scalable processors. Now, the companies give data scientists more hardware choice by optimizing the NNP-T for PaddlePaddle.

"The next few years will see an explosion in the complexity of AI models and the need for massive deep learning compute at scale. Intel and Baidu are focusing their decade-long collaboration on building radical new hardware, co-designed with enabling software, that will evolve with this new reality – something we call ‘AI 2.0,"  stated Naveen Rao, Intel corporate vice president and general manager of the AI Products Group.

China Mobile approves ZTE's CE-band 96-wavelength system

ZTE's commercial CE-band 96-wavelength beyond 100G OTN system passed the on-site test of Hubei Branch of China Mobile and the FOA network access test of China Mobile Group.
Compared with the traditional C-band 80-wavelength 100G system,

ZTE’s CE-band 96-wavelength 200G system increases the capacity by 140% compared with a C-band 80-wavelength 200G system.

In August 2018, ZTE cooperated with Hubei Branch of China Mobile to build the new provincial backbone beyond 100G IDC network, adopting the CE-band 96-wavelength 200G system. This system implements electrical cross-connection to achieve fast connection.

By means of the fast assignment of ROADM system wavelengths, it supports flexible hybrid scheduling of optical and electrical layer services, thereby improving service provisioning and operation efficiency.  Meanwhile, the solution provides multiple routing channels and supports one-hop transmission on the optical layer, enabling lower network latency and mesh network services.
