Telefónica Germany's O-RAN trial employs ADVA's Ensemble Activator

ADVA is playing a key role in Germany’s first open radio access network (O-RAN) proof of concept (PoC), which is being conducted by Telefónica Germany / O2.

The multi-vendor PoC is built on ADVA’s Ensemble Activator running on Edgecore’s switching device. Developed as part of the Telecom Infra Project (TIP), the software frees mobile network operators (MNOs) from closed proprietary systems and enables them to create vendor-neutral disaggregated infrastructure with best-of-breed components. 

ADVA's pluggable OSA 5401 PTP grandmaster is providing crucial advanced synchronization functionality,  including the ability to send PTP sync information and corresponding messages with precise timestamping data. The OSA 5401 also makes this advanced operation compatible with 5G radio access points from third-party suppliers and augments the accurate timing needed.

“This PoC is an important stage in our journey towards open 5G networking. It shows how we can achieve the scale and agility needed for the widespread rollout of next-generation mobile services and underlines the benefits of vendor collaboration and interoperability,” commented Matthias Sauder, director, mobile access network, Telefónica Germany / O2. “With this open RAN pilot in our O2 live network, we’re highlighting what can be achieved when industry leaders from across the value chain cooperate closely together in an open environment. We’re also proving that a disaggregated model built on affordable software-empowered hardware can deliver transport infrastructure with new levels of efficiency – for 4G as well as 5G networks in the future.”

“By harnessing our high-performance NOS and compact timing solution, Telefónica Germany / O2 is taking a big step towards open and disaggregated 5G networking. This PoC shows how it will be able to utilize RAN technology from multiple vendors and leverage the full benefits of separated software and hardware,” said Eli Angel, VP, product line management, ADVA. “As we’re proving in multiple real-world trials with major MNOs, our Ensemble Activator is the ideal choice for turning third-party white box switches from a wide range of suppliers into disaggregated cell site gateways (DCSGs). What’s more, our OSA 5401 provides the strict timing and interoperability needed for an open model. To put it simply, our technology is the key to making open RAN work.”

ONF launches 5G SD-RAN Project

The Open Networking Foundation (ONF) has launched an SD-RAN project with the aim of building an open source Near Real-Time RAN Intelligent Controller (nRT-RIC) compatible with the O-RAN architecture as well ONF’s existing base cloud-native solutions leveraging disaggregation and whitebox hardware.

ONF said its goal is to foster open source software platforms and multi-vendor solutions for mobile 4G and 5G RAN deployments.

Central to the project is the development of an open source near-real time RIC called µONOS-RIC (pronounced “micro-ONOS-RIC”).

µONOS is a microservices-based SDN controller created by the refactoring and enhancement of ONOS, the leading SDN controller for operators in production tier-1 networks worldwide.  µONOS-RIC is built on µONOS, and hence features a cloud-native design supporting active-active clustering for scalability, performance and high availability along with the real-time capabilities needed for intelligent RAN control. The O-RAN ALLIANCE E2 interface is used to interface between µONOS-RIC and vendor supplied RAN RU/DU/CU RAN components.

Carriers would be able to run new "xApps" on top of the µONOS-RIC.  These open xApps could provide functionality that traditionally has been implemented in vendor-proprietary implementations, including providing visibility and control over the RAN.

Significantly, the ONF's SD-RAN project is backed by AT&T, China Mobile, China Unicom, Deutsche Telekom, Facebook, Google, Intel, NTT, Radisys and Sercomm.

A working skeleton prototype of the µONOS-RIC controller is already running above a RAN emulation platform through the E2 interface.  ONF has demonstrated handover and load balancing at scale, supporting over 100 base stations and 100,000 user devices with less than 50ms handover latency (less than 10ms latency for 99% of all handovers). Field trials are expected by early 2021.

“AT&T strongly supports the development of specifications and components that can help drive openness and innovation in the RAN ecosystem. The O-RAN ALLIANCE’s specifications are enabling the ecosystem, with a range of companies and organizations creating both open source and proprietary implementations that are bringing the open specifications to life. The ONF SD-RAN project, along with the O-RAN OSC, will expand the ecosystem with an nRT-RIC that can support xApps and help demonstrate their interoperability. This project will help accelerate the transition to an open RAN future,” stated Andre Fuetsch, President and Chief Technology Officer, AT&T Labs.

“Google is an advocate for SDN, disaggregation and open source, and we are excited to see these principles now being applied to the RAN domain. ONF’s SD-RAN project’s ambition to create an open source RIC can help invigorate innovation across the mobile domain, said Ankur Jain, Distinguished Engineer, Google.

ONF's Aether targets Enterprise 5G/LTE-Edge-Cloud-as-a-Service

The Open Networking Foundation (ONF) announced Aether – the first open-source platform for delivering Enterprise 5G/LTE-Edge-Cloud-as-a-Service.

Aether (pronounced ‘ee-ther’) provides mobile connectivity and edge cloud services for distributed enterprise networks, all provisioned and managed from a centralized cloud.


Aether leverages existing work from ONF including the CORD and ONOS platforms. It can be run in a Kubernetes environment, and it simultaneously supports deployment on licensed (4G/5G) and unlicensed (CBRS) spectrum.

“Aether opens the door for enterprises to rapidly deploy 5G and edge cloud services to help power their digital transformations. This can be done with a variety of flexible business models including in collaboration with telco operators, cloud operators, and third party providers. It offers the flexibility to utilize a wide range of bands including 5G, licensed bands, and CBRS. This cloud-enabled platform turns mobile connectivity and enterprise mobile edge cloud capabilities into a cloud-managed service, simplifying deployment and operations while delivering scalable and cost-effective services,” states Guru Parulkar, Executive Director, ONF & Executive Director, Stanford Platform Lab.

ONF already has a modest Aether pilot production network supporting edge cloud services running at two ONF offices, Intel Labs, and at other sites. This pilot is centrally managed and controlled from public cloud, with Aether Edge installations at each site. The entire deployment is maintained by ONF and ONF members using a distributed CI/CD DevOps development pipeline.

As with all ONF projects, Aether is backed by ONF’s operator partners AT&T, China Unicom, Comcast, Deutsche Telekom, Google, NTT Group and Turk Telekom. Additionally, ONF, Intel, GSLab, Infosys, and Accelleran are actively collaborating as a distributed DevOps team enhancing and maintaining Aether.

Vodafone activates first OpenRAN site in UK

Vodafone activated an Open Radio Access Network (OpenRAN) 4G site Powys, Wales - the first OpenRAN site to enter commercial service in the UK.

OpenRAN provides mobile network operators with greater flexibility in choosing infrastructure equipment providers.

Mavenir is supporting Vodafone with this deployment at the Royal Welsh Showground in Powys.

Scott Petty, CTO, Vodafone UK, said: “This is our first live OpenRAN site in the UK, and that’s an important milestone. This new approach has the ability to make us less dependent on current larger technology suppliers, and find ways to reduce the cost of rolling out mobile coverage. OpenRAN can also help close the digital divide between urban and rural Britain.”

Matt Warman, Digital Infrastructure Minister, said: “OpenRAN gives mobile companies the flexibility to use multiple suppliers in their 4G and 5G networks. This is vital to help the market grow, build resilience and give people fast, reliable and secure internet connections wherever they live and work.
