Rakuten invests in Altiostar for virtual RAN

Rakuten, the Japanese e-commerce and fintech company and soon to be the operator of Japan’s newest mobile network, will make a strategic investment in Altiostar Networks, a start-up based in Tewksbury, Mass. The investment is subject to approval by the Committee on Foreign Investment in the United States.

Altiostar provides a 5G-ready virtualized RAN software solution that supports open interfaces and disaggregates the hardware from the software to build an open multi-vendor web-scale network. The Altiostar solution supports macro and small cells, indoor and outdoor, enabling interference management, carrier aggregation and dual reception.

Rakuten said it is on track with the deployment of a fully virtualized mobile network in Japan by October 2019.

“Our vision for Rakuten Mobile Network is to build the world’s first end-to-end, fully virtualized, software-defined mobile network: A network that innovates at the Speed-of-Software and scales at the Speed-of-Cloud. Altiostar technology is key to realizing this vision within the year,” said Tareq Amin, CTO of Rakuten Mobile Network. “The whole Rakuten team is looking forward to working closely with Altiostar to take a leadership role in driving RAN virtualization and to bring disruptive innovation to the mobile industry.”

“Open RAN architecture and virtualization are key to building software-centric networks that can scale and adapt to meet an explosion of devices and applications driving service velocity and profits,” said Ashraf Dahod, CEO of Altiostar Networks. “This funding is going to help us expand our technology innovation to help operators like Rakuten to push new business models and bring affordable broadband to the masses through web-scale mobile networks.”

In addition to the investment, Rakuten Mobile Network President Yoshihisa Yamada and Chief Technology Officer Tareq Amin will join the board of Altiostar upon completion of the transaction.

Softbank implements Machine Learning in the RAN with Ericsson

SoftBank is using machine-learning software developed by Ericsson for advanced radio network design in the Tokai region. The service groups cells in clusters and takes statistics from cell overlapping and potential to use carrier aggregation between cells into account, thus reducing operational expenditure and improving network performance. The machine learning evaluates cell coverage overlap, signal strength and receive diversity. Big data analytics was applied to a cluster of 2000 radio cells and data was analyzed for the optimal configuration.

Ericsson’s centralized and elastic radio access network design is sold as a service and supports LTE networks. Ericsson says that compared to traditional network design methods, the ML approach cuts the lead time by 40 percent.

Ryo Manda, Radio Technology Section Manager at the Tokai Network Technology Department of SoftBank, says: “We applied Ericsson’s service on dense urban clusters with multi-band complexity in the Tokai region. The positive outcome exceeded our expectations and we are currently proceeding in other geographical areas with the same method and close cooperation with Ericsson.”

Peter Laurin, Head of Managed Services at Ericsson, says: “There is a huge potential for machine learning in the telecom industry and we have made significant investments in this technology. It is very exciting to see that the new methods have been successfully applied in SoftBank’s network. There is a strong demand for this type of solutions and deployments of this service to other tier-one operators in other regions are ongoing.”

xRAN Forum merges with C-RAN Alliance, seeking innovation in radio access

Two industry organizations are combining their efforts to drive innovation in radio access networks.

The xRAN Forum will merge with the C-RAN Alliance to form the ORAN Alliance, which is backed by AT&T, China Mobile, Deutsche Telekom, NTT DOCOMO, and Orange.

  • The key principles of the ORAN Alliance include:
  • Leading the industry towards open, interoperable interfaces, RAN virtualization, and big data enabled RAN intelligence.
  • Maximizing the use of common-off-the-shelf hardware and merchant silicon and minimizing proprietary hardware.
  • Specifying APIs and interfaces, driving standards to adopt them as appropriate, and exploring open source where appropriate.

“xRAN Forum members have made excellent progress this year and we expect completion of the first open, interoperable front haul specification in March,” said Dr. Sachin Katti, Professor at Stanford University and Director of the xRAN Forum. “We are advancing both a southbound interface specification to an open RAN and a northbound interface specification, delivering applications access to rich controller functions and abstracted RAN control. Going forward, we believe there will be strong, complimentary collaboration with our new colleagues from the C-RAN Alliance.”

“The xRAN Forum was created to accelerate the delivery of products that support a common, open architecture and standardized interfaces that we, as operators, view as the foundation of our next-generation wireless infrastructure,” said Alex Jinsung Choi, SVP Research & Technology Innovation, Deutsche Telekom. “xRAN members have made strong progress this year, and we are confident that by building on the xRAN architecture in combination with the RAN virtualization focus brought by the C-RAN Alliance, we are well positioned to achieve the joint objectives of the ORAN Alliance.”

"Our industry is approaching an inflection point, where increasing infrastructure virtualization will combine with embedded intelligence to deliver more agile services and advanced capabilities to our customers. The xRAN Forum has been at the forefront of defining the next generation RAN architecture for this transformation," said Andre Fuetsch, CTO and President AT&T Labs. "This is a global change that will impact all network operators. It will be accelerated by the merger of the xRAN Forum and the C-RAN Alliance into the ORAN Alliance, which promises to be a strong global forum."

#MWC16: Ericsson Expects First Virtual RAN Trials this Year

Ericsson expects its first Virtualized RAN field trial with a mobile operator in 2016. The company said the adoption of cellular IoT and Low Power Wide Area (LPWA) networks supporting millions of IoT device connections per cell site will drive the need for Cloud RAN flexibility.

Ericsson Virtualized RAN enables Virtual Network Functions (VNF) to be supported on a split architecture, with parts of the protocol stacks centralized on commercial off-the-shelf (COTS) hardware, while others are decentralized. Ericsson enables both RAN and core functionality to be co-hosted on the same server, increasing the operational simplicity and savings enabled by virtualization without compromising on performance.

Ericsson's live Cloud RAN demonstration at MWC 2016 this week features radio access functionality virtualized on remote servers located in Sweden, including virtual instances of the Radio Resource Control Function (RRCF) and Packet Data Conversion Protocol (PDCP) function.

Ericsson is also showcasing its end-to-end role in the Network Functions Virtualization (NFV), including virtual EPC gateway functionality for local breakout of specific services or devices.
