Telecom technology integrator Telefónica Tech has signed an agreement with IBM/Red Hat to integrate Red Hat’s OpenShift platform into a new cloud service marketed at enterprises across Telefónica’s footprint in Europe and Latin America.
The integration will be marketed as the Telefónica Red Hat OpenShift Service (TROS), which will tap into the use of containers to help organizations modernize their cloud applications and drive their digital transformation. It will allow those organizations to migrate applications to hybrid cloud or multi-cloud environments using either private or public clouds from hyperscalers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP).
OpenShift is based on the Kubernetes container orchestration project that allows for the migration of applications across different cloud and on-premises environments. A recent report from TBR Senior Analyst Catie Merrill noted that Red Hat’s OpenShift platform has four-times as many customers as it did before IBM acquired the company for $34 billion in mid-2019.
Red Hat OpenShift differentiates itself by combining multiple hardened open source technologies to provide a more complete modern application platform, enabling organizations to use it as the foundation for current and future IT strategies. Additionally, the use of Red Hat OpenShift allows for use in any type of cloud, facilitating the creation of this Multi-Cloud service for Telefónica Tech.
This new, open hybrid, multi-cloud approach will allow Telefonica Tech to strengthen and differentiate its value proposition, and provide more flexibility to its customers in their digital transformation and application modernization in the markets where Telefónica Tech is present.
The complementary nature of cloud technologies integrated in TROS will enable Telefónica Tech, Red Hat and IBM to jointly define innovative use cases and provide high value-added professional services to customers to help them make the process more efficient, cost-effective and cost-optimal.
The strategic agreement also enables Telefónica Tech to develop additional services on TROS based on Red Hat technologies and IBM Cloud Paks so that customers can accelerate their transformation to cloud-native applications, enabling a more consistent user experience both in their own cloud and on the hyperscalers.
María Jesús Almazor, CEO of Cybersecurity and Cloud at Telefónica Tech, said: “This strategic agreement allows us to strengthen our differential multicloud offer by integrating world class technologies from Red Hat and IBM and consolidate our position as a leading partner for the digital transformation of businesses. We continue to evolve our ecosystem of alliances to enhance the digital capabilities of our professionals and to include in our portfolio the most innovative proposals in the market, fundamental aspects to continue offering the best service to our customers.”
Horacio Morell, IBM General Manager for Spain, Portugal, Greece and Israel: “This alliance enables us to take a quantum leap in our business collaboration with Telefonica Tech to continue co-creating enterprise multi-cloud and cybersecurity solutions that will enable companies around the world, across all industries, to implement their technology transformation strategies with greater speed, consistency and agility, while ensuring data control, privacy and reliability and increasing decision-making efficiency through the unique capabilities of IBM’s technologies.”
Julia Bernal, Country Manager for Spain and Portugal at Red Hat, said: “Red Hat is fully committed to helping our customers and partners optimize their business with open hybrid cloud and focus on innovation rather than simply managing their IT infrastructure. Our mission is to mitigate the complexities of modern cloud-scale IT environments and with managed cloud services they can do just that. Telefónica Red Hat OpenShift Service enables customers to free resources to create and manage applications more quickly across multiple clouds, streamlining time to market and accelerating growth opportunities.”
“It is going to be the way forward and what many customers who want to evolve their business models,” said Santiago Madruga, VP for ecosystem success in EMEA at Red Hat, in an interview with SDxCentral. “When going digital, it’s not just putting workloads on the cloud but really transforming businesses.” Madruga added that the use of OpenShift also allows for the micro-segmentation of application components that will open the door for edge distributed cloud work.
Microsoft and Telefonica Tech, Telefonica’s digital business unit, has signed a new deal with Microsoft, to supply confidential hybrid cloud services to public administrations and companies in regulated sectors. The focus will be on monitoring and encryption services to ensure the security and privacy of data in Microsoft Azure, Microsoft 365 and Microsoft Dynamics 365.
- The joint solutions of both companies will enable Spanish public administrations and companies in regulated sectors to respond to the needs of digital sovereignty.
- Telefónica Tech and Microsoft meet the most demanding legal and technical requirements for cloud trust principles, guaranteeing them with Microsoft’s Confidential Computing technology and Telefónica Tech’s cyber threat monitoring and management capabilities.
- Telefónica Tech will provide professional and managed advisory, implementation, and operational services to deploy and operate the cloud services, which will be marketed through Telefónica Empresas.
Under the latest agreement, Microsoft will deliver its privacy safeguards, technologies and certifications. The company has high-level National Security Scheme certification for Azure, Microsoft 365 and Dynamics 365 and has made a contractual commitment to legally oppose access to its enterprise and public sector customer data by any government. Microsoft has also announced the EU Data Boundary initiative to allow customers to store and process their personal data within the EU. This commitment applies to Microsoft Azure, Microsoft 365 and Dynamics 365 cloud services.
Telefonica Tech will provide consultancy, implementation and operation services that will enable the deployment of maximum security cloud services, guaranteeing compliance with information privacy, quality of service and regulatory compliance requirements at all times. The company will also deliver value-added services, such as the intelligent management of communications and infrastructures or the monitoring and management of cyber threats from its Cybersecurity Operations Centre, with the aim of guaranteeing a rapid and secure adoption of cloud services by the different organisations and institutions. It will in addition offer specialised consulting services for the design, deployment and operation of Big Data platforms on Microsoft Azure Cloud capabilities. Finally, specific services will be supplied to the Defence sector. These will include 5G connectivity services offered by Telefonica with Microsoft cloud services.
All of the services will be implemented in Microsoft’s current cloud environments and will be complemented by the upcoming availability of the new Cloud Region that Microsoft will open in Spain.
Telefonica joined Microsoft and Repsol in June to create an artificial intelligence consortium focused on the industrial sector in Spain.
Telefonica and Microsoft partnered in May to jointly develop private 5G connectivity and on-premises edge computing services for the industrial sector. The partners will now provide public sector organizations, including Defense, with cloud computing and infrastructure services to advance their digital transformation plans, while complying with data protection provisions and recommendations defined by the European Data Protection Board (EDPB).
José Cerdán, CEO of Telefónica Tech, assures: “We believe that the alliance between Microsoft and Telefónica represents a giant step forward in enabling the digital transformation of the public sector and, in general, of the country. The combination of Microsoft’s technology with Telefónica’s service, management and control capabilities guarantees sovereignty and privacy as well as scalability and evolution of infrastructure and citizen services, all with the highest level of quality“.
Alberto Granados, president of Microsoft Spain, remarks: “We at Microsoft have long demonstrated our commitment to meeting and exceeding the data protection requirements of the European Union. This joint value proposition with Telefónica to provide confidential hybrid cloud solutions responds to the needs of digital sovereignty and is evidence that we continue to advance this commitment.”
Regarding this alliance, Carme Artigas, Secretary of State for Digitalization and Artificial Intelligence, points out: “The proposal of confidential public cloud solutions together with hybrid cloud designed specifically for public administrations and companies in regulated sectors in Spain, responds to the important objective of digital sovereignty and constitutes a very relevant advance to accelerate the digitalization of our economy.”
Microsoft was the first hyperscale cloud provider to achieve certification for compliance with the high level of the National Security Scheme in 2016, demonstrating the company’s commitment to delivering cloud products with the highest security requirements. This certification is available for all three Microsoft public clouds: Microsoft Azure, Microsoft 365 and Dynamics 365. It has also been the first to provide Confidential Computing services working with Intel and AMD. These Microsoft cloud services add in-use protection to existing protections for data in transit and at rest, ensuring maximum privacy. In addition, the company offers advanced encryption services that complement the base encryption measures, allowing the implementation of encryption systems using keys provided and managed by the customer or a third party, in this case Telefónica, and managed and dedicated hardware security module (HSM) services.
Telefónica Tech, through its capabilities and experience, accelerates the implementation of technology through its Cybersecurity, Cloud, IoT, Big Data, Artificial Intelligence and Blockchain services. It has 12 specialized Digital Operations Centers (DOC) with 24×7 services from where more than 30,000 servers are managed and more than 100 million cybersecurity events per year are monitored. It also has more than 3,000 expert professionals with the highest certifications in cloud services and cybersecurity who serve the Telefónica Group’s 5.5 million B2B customers in 175 countries.
IBM has been awarded a multi-year contract to help Telefonica build its new ‘Unica Next’ cloud-based 5G core network platform. In a statement, IBM said the Spanish operator has engaged IBM Global Business Services – the consultancy arm of IBM, Red Hat and Juniper Networks – to deploy an “open-standard open-networking” platform across multiple central, regional and distributed data centers to deliver low latency and high bandwidth services.
As a member of the IBM Cloud for Telecommunications ecosystem, Juniper is proud to support IBM and Red Hat as they work with Telefónica to build and deploy a modern 5G network. Juniper says it is committed to bringing the power of open hybrid cloud architecture to clients around the world.
The partners said the first Unica Next data centers are set to be inaugurated in October 2021 with a scalable architecture designed to address ETSI and other relevant industry standards (there are none for 5G SA core network). The new network is built on IBM Cloud Pak for Network Automation, Red Hat OpenShift and Juniper Networks Apstra and QFX technology to deliver end-to-end orchestration and operations.
These new capabilities will be engineered to allow Telefónica to more quickly deploy network services and new network functions, leveraging the IBM Cloud for Telecommunications partner ecosystem. Telefónica, as a pioneer in the adoption of open networks, has already deployed a live implementation using the IBM Cloud for Telecommunications in Europe and is continuing to innovate for their customers with speed and improved value.
IBM added that the combination will give Telefonica increased observability and control for managing the Unica Next Kubernetes environment and drive 5G and edge innovation more quickly and with less complexity. Its IBM Cloud Pak for Network Automation product is AI-powered automation software designed to provide extreme automation, zero-touch provisioning and closed loop operation capabilities.
“We are proud to partner with Telefónica to reach this historic moment for the telecommunications industry in Europe,” said Steve Canepa, managing director, IBM Global Communications Sector. “This implementation of Telefónica’s cloud-native, 5G core network platform reflects IBM’s significant investments in AI-powered automation software and the telco prime systems integration expertise required to deploy modern telecommunication networks – core, access, and edge. We are energized by the opportunity to enable Telefónica and all our clients to modernize their networks and enable new revenue-generating services that deliver tremendous value to consumer and enterprise customers.”
IBM Global Telco Solutions Lab in Coppell, Texas, connected along with Telefónica’s Network Cloud Lab in Madrid, will help accelerate UNICA Next’s evolution by building new fully integrated releases using CI/CD methodology for ongoing life-cycle upgrades to the existing UNICA Next platform. By working with IBM in this way, Telefónica will be able to increase agility and data security and continue to innovate and transform, drawing on IBM’s large network function ecosystem, Red Hat’s vast ecosystem of certified partners, and Juniper’s relationships with network function and hardware vendors.
Telefonica has already deployed a live implementation of the open network using the IBM cloud for telecommunications in Europe. The partners also announced that IBM Global Telco Solutions Lab in Coppell, Texas, will be connected to Telefonica’s Network Cloud Lab in Madrid to help accelerate Unica Next’s evolution by building new fully integrated releases using CI/CD methodology for ongoing life-cycle upgrades.
“Building out the UNICA Next platform with its next-generation network architecture shows how important it is to build the infrastructure now to support the deployment of 5G. 5G has the potential to support thousands of use cases and applications for consumers and enterprises in all industries. Our collaboration will not only help us to harness the potential of 5G, but also prepare for the future through a hybrid-cloud led technology and business transformation. With IBM, Telefónica is combining the latency and bandwidth advancements of 5G with the customization and intelligence of the cloud: we anticipate the results will be transformative in Europe and beyond,” said Javier Gutierrez, director of strategy, network, and IT development for Telefónica.
It’s interesting that last year, Telefónica Germany said it would build it’s 5G core network on AWS for the public cloud infrastructure and Ericsson for the core and orchestration components.
Telefonica España will begin the commercial deployment of a 10 Gbps fiber broadband network using XGS-PON technology in Spain in the first half of 2022, reports website bandaancha.eu.
The gradual rollout is part of Telefonica’s ‘Banda Ancha Abierta‘ (Open Broadband) project to install an efficient, open, scalable and virtualized network model that will facilitate fixed-mobile convergence (fixed access with mobile backhaul), Multi-access Edge Computing capabilities ( MEC), and the deployment of third-party applications.
Telefónica’s FTTH network in Spain passes 26.1 million homes as of June 2021, for which 4,726,700 clients are served through the Movistar and O2 brands. In addition, there are 2,801,700 clients of other operators served through indirect fiber optics.
The introduction of XGS-PON will introduce two new lambdas or wavelengths on the existing GPON fiber infrastructure. The same fiber cable will carry wavelengths corresponding to GPON and in parallel new colors of the laser for XGS-PON so that the two technologies do not interfere with each other.
XGS-PON raises the available throughput for an entire fiber branch to 10 Gbps downstream and 10 Gbps upstream for up to 64 client endpoints. That will permit Telefonica to commercialize speeds of up to 2.5 Gbps symmetric and, in the medium term, up to 10 Gbps.
XGS-PON requires new customer premises equipment. Telefónica customers have been waiting for years for the new XHGU router that the operator announced in 2018 and that is compatible with XG-PON, in addition to bringing high-penetration WiFi 6.
With the arrival of XGS-PON, Movistar will begin to distribute this new router or temporarily provide an ONT XGS-PON.
In a related story, DELTA Fiber has attracted 2 billion euros to back a planned roll-out of XGS-PON technology throughout the Netherlands. The 10G PON deployment will expand DELTA Fiber’s network to 2 million fiber connections in 2025. It currently expects to reach 1 million connections by the end of this year.
The company expects to begin rolling out XGS-PON this September. It will use the technology exclusively in its future builds with an eye toward making gigabit broadband widely available.
DELTA Fiber also said it plans to deploy 25G PON in the future. Along these lines, the company recently announced a partnership with Proximus of Belgium to deploy fiber to the home networks in Flanders. Proximus has already adopted 25G PON technology.
With this initiative the intention is also to begin building services for customers to be marketed via Telefónica’s 5G network. The project will thus enable Telefónica to obtain key results that will serve to drive the ecosystem and promote the interoperability and standardisation of this technology with a view to its marketing towards the end customer. Some of the sectors that can benefit the most from Network Slicing are the State Security Corps and Forces, media and communication, cars, industry and hotels.
Rakuten Mobile, Inc., and Telefónica, S.A. announced today the signing of a Memorandum of Understanding (MoU) to cooperate on a shared vision to advance OpenRAN, 5G Core and OSS (operations support systems).
“We’re excited to collaborate with Telefónica on this shared vision of advancing OpenRAN,” said Tareq Amin, Representative Director, Executive Vice President and CTO of Rakuten Mobile. “I envision our partnership to also co-explore further development around the Rakuten Communications Platform that will enable operators around the world to take advantage of cost-effective cloud-native mobile network architecture that is secure and reliable.” (Emphasis added)
Amin emphasised the partnership is not just about opening the interfaces: “It’s about the future possibilities when these networks become fully autonomous. What makes a difference is automation, as it enables much needed operational savings. We’re going to spend a lot of energy around joint development of automation, especially what we call OSS transformation to move away from legacy systems.”
Enrique Blanco, Chief Technology & Information Officer (CTIO) at Telefónica, said: “Telefónica strongly believes that networks are evolving towards end-to-end virtualization through an open architecture, and OpenRAN is a key piece of the whole picture. Beyond the flexibility and simplicity that OpenRAN will provide, it will change the supplier ecosystem and revolutionise the current 5G industry in the medium and long term. At the same time, open and virtualized networks will lead to a new telco operating model. Telefonica and Rakuten Mobile have signed this MoU to work towards evaluating and demonstrating the capability and feasibility of OpenRAN architectures and make them a reality.”
“This is a massive opportunity for all of us. This is an inclusive approach and how we can guarantee we are building the network for the future,” Blanco added. In addition to defining the interfaces, the companies are exploring procurement of hardware and software, Blanco said.
Under the terms of the MoU, Rakuten Mobile and Telefónica plan to collaborate on the following:
- To research and conduct lab tests and trials to support OpenRAN architectures, including the role of the AI (Artificial Intelligence) in the RAN Networks.
- To jointly develop proposals for optimal 5G RAN architecture and OpenRAN models as part of industry efforts to achieve quicker time to market, new price-points, and the benefits of software-centric RAN.
- To collaborate in building an open and cost-effective 5G ecosystem, based on open interfaces, that will help accelerate the maturity of 5G with global roaming.
- To develop a joint procurement scheme of OpenRAN Hardware and Software that will help increase volumes and reach economies of scale, including CUs, DUs, RRUs, and other necessary network equipment and/or software components.
In addition, the companies will also jointly work on 4G/5G Core and OSS technology utilized by Rakuten Mobile in Japan and its Rakuten Communications Platform.
“Vendor selection typically takes a long time in the telecoms industry compared with the web-scale companies. Maybe together with Telefonica the discussions with vendors might change a bit and require us to create new business models.”
Telefonica plans to introduce open RAN in three phases, with pilots starting this year, initial rollouts in 2021 and mass deployments in 2022. “I’m extremely convinced we’ll hit these targets, but we are trying to be conservative,” Blanco said. From 2022 to 2025, up to half of Telefonica’s 5G deployments will use open RAN, he added.
Why this MOU is IMPORTANT:
- As there are no ITU recommendations or 3GPP specs detailing how to implement a 5G Core/5G SA network, the Rakuten-NEC 5G core could become a defacto standard. As we’ve stated many times, the 3GPP specs on 5G Core are network architecture specs that leave the various implementation choices to the implementer. And 3GPP is not even sending their 5G non-radio specs to ITU-T for consideration as future recommendations.
- Meanwhile, Rakuten and NEC have created a 5G “cloud native” core spec (proprietary of course) built on containers, which NEC (and likely other vendors) will implement in Rakuten’s 5G network. Rakuten and NEC plan to offer there 5G Core as a product to other 5G network operators.
- The Rakuten Communications Platform for Open RAN could similarly be sold to other carriers that want to deploy an Open RAN 4G/5G network. The catch here is that any legacy wireless carrier wanting to do so would have to support two incompatible sets of cellular infrastructure to serve its customers: 1] The traditional “closed box base stations” (from Huawei, Ericsson, Nokia, Samsung, ZTE, etc) in cell towers AND 2] The new Open RAN, multi-vendor base stations using totally different hardware/software platforms which requires a significant amount of systems integration and tech support/trouble resolution. Rakuten’s platform could, at the very least, simplify systems integration and avoid “finger pointing” when troubleshooting a failure or degraded service.
- Both the Rakuten-NEC 5G Core and Rakuten Communications Platform for Open RAN could be terrific products to sell to greenfield carriers (with no existing wireless infrastructure). Apparently, that’s too late for Dish Network and Reliance Jio, which claim they’re building their own “open 5G” network. Meanwhile, India based Tech Mahindra claims it can build a complete 5G network now, which they would surely sell to would be 5G network providers, utilities, and government agencies around the world.
- The OSS co-operation amongst these two carriers is significant, because (once again) there are no standards for 5G SA OSS’s such that the deliverable output of cooperation here could become a defacto standard.
- Co-operative work on automation of network functions and operations will also be vitally important. Otherwise, that too will be proprietary to the wireless network provider which would require different software for the SAME functions for different carriers. The work will probably start with these 2800 series 3GPP specs: TS 28.554 Management and orchestration; 5G end to end Key Performance Indicators (KPI); TS 28.555 Management and orchestration; Network policy management for 5G mobile networks; Stage 1 TS 28.556 Management and orchestration; Network policy management for 5G mobile networks; Stage 2 and stage 3. There are similar ITU-T SG 13 high level Recommendations on these subjects.

Telefónica has launched commercial 5G services throughout Spain, pledging to reach 75 percent of the Spanish population by the end of the year. In a statement, the company’s executive chairman Jose Maria Alvarez-Pallete described the deployment as the most ambitious in the European Union. “The launch of 5G is a leap forward towards the hyperconnectivity that will change the future of Spain,” he said, noting that “it’s 5G for everyone, without any exceptions, in all the autonomous communities.” [That assumes low enough 5G tariffs, such that poorer working class Spaniards can afford the service]. Telefonica is accelerating “the digitalisation of small and medium companies, public administrations and citizens, ”Alvarez-Pallete added.
“Our network has always been a differential asset. People’s lives pass through it and it has demonstrated unparalleled strength when it’s been most needed”, Álvarez-Pallete continued. He pointed out that Spain already leads Europe’s digital infrastructures with the largest fiber optic network.
Editor’s Note: Telefonica’s 5G announcement follows Vodafone – Spain‘s commercial 5G network deployment in 21 cities in Spain. Initial 5G speeds of up to 1 Gbps for Vodafone subscribers in Madrid, Barcelona, Valencia, Seville, Malaga, Zaragoza, Bilbao, Vitoria, San Sebastian, La Coruna, Vigo, Gijon, Pamplona, Logrono and Santander. Speeds will rise to 2 Gbps by the end of the year, some 10 times the current 4G maximum, with latency reduced to less than 5 milliseconds in ideal conditions.
Orange and Masmovil set to launch their 5G networks in Spain this month. All four of Spain’s MNOs (Mobile Network Operators) are expected to bid for frequencies in the 700 MHz band when the government holds its delayed spectrum auction in the first quarter of 2021.
Telefonica said 5G technology will give residential customers access to far faster speeds and lower latency, allowing sports fans to enjoy live 360-degree broadcasts and mobile gamers to access a “fibre-like” experience. Businesses will have access to services such as Multi-Access Edge Computing, 5G private networks, mass IoT and critical communications, as well as network virtualisation to facilitate more effective use of the network’s resources.
The Spain based network operator (also active in Latin America) clarified that it will initially launch NSA (non-standalone) 5G combined with DSS (Dynamic Spectrum Sharing) ahead of the “immediate deployment” of 5G SA (standalone) when the technology becomes fully available after standardisation. The company said it will make use of its current sites and infrastructure for the initial rollout, to be complemented by new base stations and small cells according to capacity and coverage needs.
It’s also having to rely on the 3.5 GHz band, together with mid-band (1800-2100 MHz) frequencies, for the initial coverage thanks to equipment that can operate with 4G and 5G at the same time. Telefonica also announced that it intends to shut down its 3G network in 2025, when 100 percent of its copper network will have been replaced by fiber optics.
“With 5G everything happens in a millisecond. A millisecond is what makes remote surgery, autonomous cars, the smart management of energy resources and cities and highly advanced entertainment possible. A millisecond is much more than a new response time. It’s Telefónica’s response to the new times. It’s Telefónica’s commitment to the country’s future”, concluded Álvarez-Pallete.
For residential customers, in addition to the benefits brought by 5G in terms of greater speed and lower latency, which will allow them, for example, to download a film in seconds, 5G will provide the possibility, among other features, of enjoying live sports broadcasts during which users will obtain a 360º experience and be able to view any angle of the match as if they were on the pitch itself. Gaming enthusiasts will obtain a mobility experience similar to that provided by fibre in the home, in other words, without any interruptions or latency. 5G will thus enable them to play on their mobile phones as if they were on their home computer screens or their video consoles.
5G business customers will have access to services like Multi-Access Edge Computing, which offers ultra-low latency services and greater computing capacity “on the network edge”, in addition to services such as 5G private networks, mass IoT and critical communications, as well as network virtualisation to facilitate more effective use of the network’s resources in keeping with the customers’ needs.
Telefónica operates with the latest radio (base station) generations that allow dual 4G and 5G usage, with the aim of bringing 5G to the largest number of people from the outset. This first phase will witness the launch of the 5G network, thanks to a technology that combines the deployment of NSA (non-standalone) 5G and DSS (Dynamic Spectrum Sharing) and the subsequent immediate deployment of the SA (standalone) 5G network when the technology becomes fully available after standardisation. This initial deployment will also make use of the current sites and infrastructure and, in the mid and long terms, it will be complemented by new base stations and small cells as the capacity and coverage require.
The 3.5 GHz band frequency (the only 5G band frequency already licensed to operators) and the mid-band (1800-2100 MHz) frequencies are being used for this purpose. This is the current location of 4G, capitalising on the possibility of using NR (New Radio) equipment that can operate with both technologies (4G and 5G) at the same time.
The new deployments will take place in tandem with a gradual shut-down of the old second and third-generation networks. 100% of the copper network will have been replaced by fibre by 2025, when the 3G network will also be shut down. This will permit more effective management of investments, as it won’t be necessary to increase them to address the new deployments.
Telefónica has announced an agreement to develop 4G and 5G Open RAN technology with partner companies Altiostar, Gigatera Communications, Intel, Supermicro and Xilinx. The Spain based pan European network operator also said it intends to launch vendor-neutral 4G and 5G Open RAN trials in UK, Germany, Spain and Brazil this year.
Telefonica said this latest collaboration comprises the necessary design and developments, integration efforts, operational procedures and testing activities required to deploy Open RAN in its networks. The Spanish network operator says this is part of its continuing efforts to lead network transformation towards 5G and that the collaboration would progress the design, development, optimisation, testing and industrialisation of Open RAN technologies across its footprint this year.
The collaboration focuses on the distributed units (DUs) and remote radio units (RRUs). The DUs implement part of the baseband radio functions using the FlexRAN software reference platform and servers based on the Intel Xeon processor. The RRUs connect through open interfaces, based on O-RAN Alliance’s fronthaul specification, and software that manages the connectivity in an open cloud RAN architecture.
Telefonica said DUs and RRUs will be designed with 5G-ready capabilities, meaning they can work in either 4G or 5G mode by means of a remote software upgrade. It will be testing the 4G and 5G hardware and software components in the lab and in the field this year, integrating an Open RAN model as part of its UNICA Next virtualization program.
The premise is that Open RAN will be cheaper as it encourages more suppliers into the market, especially in terms of the baseband hardware where economies of scale from using standard IT can be deployed.
A cloudified open radio access architecture can also enable faster software innovation and advanced features like network automation, self-optimization of radio resources and coordination of radio access nodes.
The main goal of the trial is to define precisely the hardware and software components in 4G and 5G to guarantee seamless interoperability. This includes:
• Testing the complete solution in the lab and in the field,
• Integrating the Open RAN model as part of the end-to-end virtualisation program (UNICA Next),
• Maturing the operational model, and
• Demonstrating new services and automation capabilities as offered by the Open RAN model.
The DUs and RRUs are designed with 5G-ready capabilities and so can work in 4G or 5G mode by means of a remote software upgrade.
The OpenRAN trial also supports exposure to third-party, multi-access edge computing (MEC) applications through open Application Programming Interfaces (APIs), and integration with the virtualisation activities in the core and transport networks. Open interfaces also mean that operators can upgrade specific parts of the network without impacting others.
Telefónica describes this openness to third-party MEC applications as “the cornerstone” to bringing added-value to the customers by enabling a variety of rich 5G services, like virtual and augmented reality, online gaming, connected car, the industrial internet of things (IoT) and more.
Edge-computing applications running in the telco cloud can benefit from the strong capillarity of the access network, so services can be tailored instantly to match the users’ needs and the status of the live network.
Enrique Blanco, Telefónica’s CTIO: “Once again, Telefónica is leading the transformation towards having the best-in-class networks in our Operations with our customers as key pillars. Open RAN is a fundamental piece for that purpose while widening the ecosystem.”
“Telefónica is known for its leading-edge network and has been championing open vRAN implementations to bring greater network service agility and flexibility,” said Pierre Kahhale, Altiostar Vice President of Field Operations. “By bringing together the best-of-breed innovation, Telefonica is looking to achieve this vision into their network. We look forward to supporting this transformation of Telefonica’s network.”
Heavy Reading principal analyst Gabriel Brown: “Up to now, the open RAN action has been all about 4G. In 5G, the major integrated systems vendors [Ericsson, Huawei, Nokia, Samsung, ZTE] have been supplying their state-of-the-art systems to the market for about 18 months,” creating a big gap between what is available from them and what can be sourced from the open RAN community, says the analyst. “This move by Telefónica could help to stop that gap getting too much wider.”
“Gigatera Communications and Telefonica has been actively working to ensure state of the art technologies are being deployed. We truly value our partnership as we engage and revolutionize the industry.”, Daniel Kim, President.
“Open RAN offers a way for service providers to enhance customer experiences and enable new revenue-generating applications,” said Dan Rodriguez, vice president and general manager of Intel’s Network Platforms Group. “We are collaborating closely with Telefonica and the broader ecosystem, and also participating in initiatives like the O-RAN Alliance, to help accelerate innovation in the industry.”
“Supermicro is excited to partner with Telefónica, a premier telecommunications provider, to deliver server-class 5G solutions based on Open RAN architecture,”, Charles Liang, president and CEO of Supermicro. “Working closely with Telefónica on the deployment of 5G in the significant EMEA region, Supermicro’s history of rapid time-to-market for advanced, high-performance, resource-saving solutions is a key component for the successful implementation of next-generation applications, especially as x86 compute designs migrate to the telco market.”
“Xilinx is excited to collaborate with the disruptive mobile operator Telefónica as it leads the move to O-RAN” said Liam Madden, executive vice president and general manager, Wired and Wireless Group, Xilinx. “Our adaptable technology supports multiple standards, multiple bands and multiple sub-networks, providing Telefónica with a unique and flexible platform for radio, fronthaul, and acceleration for 4G and 5G networks.”
At the 5G Core Summit 2019 in Madrid, Orange España’s Head of Product Engineering-Tomas Alonso said his company was taking its time to deploy “5G,” despite pressure from other telcos, like Vodafone-Spain and Telefónica Móviles. During his conference session titled Orange Spain on the Road to 5G, Alonso said that 5G technology is still not mature enough to make any real difference to customers and Spanish authorities are not helping operators deploy it.
Obviously that’s true, because all pre-standard 5G deployments use LTE signaling/control plane and mobile packet core (5G NSA). Also there is no ultra low latency in 3GPP Rel 15 5G NR. More on this 5G core topic below.
“I would summarize our work in two words; testing and learning. We do not launch the technology because of the technology. We launch the technology to offer a better customer experience,” said Alfonso.
Orange Spain is currently trialing 5G at various locations throughout the country, though there are no plans to speed up the commercial launch, which is currently set for some point in 2020.
Spanish wireless network operators also lack sufficient spectrum they need to provide a high-quality 5G service. Spain held its 5G auction way back in July 2018, when Orange collected 60 MHz of spectrum in the 3.6GHz-3.8GHz band. The trouble, it seems, is that telcos’ band plans look like a piano with missing keys.
“In almost all cases, the spectrum is allocated in different packets,” said Alonso. “We need to do some shuffling to have contiguous bands so that we can provide the best experience in 5G.”
“The earliest date [for an auction] is the first half of next year,” Alonso added. That spectrum will be needed for “effective and efficient” mobile rollouts, he said.
Equally important, Alonso believes the 5G network equipment currently available remains “too heavy” and too power-hungry. “To be efficient, we need to wait a bit more and then have a better ROI [return on investment] when we deploy the network,” he said. There will be a stronger business case for 5G deployment when the equipment has been improved.
Also, Orange Spain’s wireless backhaul infrastructure must be upgraded, with more fiber optics urgently needed. Orange is leveraging its investments in fiber-to-the-home networks — which today reaches more than 14 million Spanish households — and extending fiber optics links to mobile sites. But the job is not yet nearly completed.
As for the scarcity of “5G” devices: “They are all very high end today and [each] costs more than €1,000 [$1,100],” said Alonso. None is yet available that supports the “standalone” (SA) version of 5G, which uses a new 5G core network in conjunction with the 5G NR technology.
As the IMT 2020 standard is over one year away from completion, there is no European operator that can deploy a 5G mobile packet core. In the meantime, operators are deploying services based on the “non-standalone” (NSA) system, which hitches the 5G New Radio to an existing 4G core. Alonso does not sound overly impressed. “So far, we have completely defined the enhanced mobile broadband [eMBB] functionality and in the second and third steps there will be newer standards for latency and mobile IoT [the Internet of Things],” he said. “Standalone will be mature in a matter of months … The real technology that will provide all the promises of 5G is not here.”
Orange Espagne S.A.U., more commonly known by its trade name of Orange España, is a mobile network operator in Spain. It was previously known as Amena, a brand of Retevisión, (Amena means pleasant in an amusing way in Spanish) until 2005, when it was bought by France Télécom (now Orange S.A.)
According to Alonso, the biggest challenge is to change how the company works. “The way we deliver value to customers will be completely different from the way we deliver value to customers with current technology and so we are spending a lot of time on that,” he said. That overhaul appears to involve setting up dedicated 5G teams within the company and breaking down some of the silos that currently separate technical and commercial departments.
A further requirement is for some type of certifications process for security of 5G technology.(from device to access network to mobile packet core to edge network to ISP/content provider point of presence) That’s endeavor is made much more difficult with no de facto or de jure 5G security standard (the work in ITU-T on IMT 2020 security is in its infancy). “Security is something we talk about a lot, but we need the sector to complete the analysis to have certifications,” said Alonso. “That is something we need in the short term.”
–>As Vodafone and other telcos race to deploy pre-standard 5G, the lack of any security system is a huge weakness, in this author’s opinion.
Network sharing is another important issue which the Orange Spain team will have to consider. This will probably not prevent the telco from launching 5G services, though it will impact the rollout strategy. Reports have emerged suggesting the team is in conversation with Telefonica and MásMóvil over sharing non-critical 5G sites. The idea of network sharing is becoming increasingly popular with telcos around the world, and it is easy to see why. During her own presentation, Lucy Lombardi of Telecom Italia quoting research from McKinsey, suggesting network sharing agreements could save as much as 40% of deployments costs for a telco. 5G is going to be a very expensive business, and any opportunity to reduce the financial burden will be strongly considered.
Some might disagree with the position of Orange Spain, but being first doesn’t necessarily mean best. Orange has shown itself to be one of the more considered, long term focused and successful telcos in Europe in recent years, so it would be quite reasonable to have confidence in the team.
The Low Power Wide Area Network (LPWAN) market is focused on IoT WAN connectivity for devices (endpoints) that consume low power, send/receive short messages at low speeds, and have low duty cycles. There are two categories of LPWANs:
1] Cellular (e.g. NB-IoT and LTE Category M1) WANs using licensed spectrum.
2] Wireless WANs operating in unlicensed frequency bands.
While cellular may be the ultimate winner, Sigfox and LoRAWAN currently have a lot more market traction and are growing very fast. Other non-cellular LPWANs (Ingenu, Weightless SIG, etc.) are also getting some attention, but if there are too many commercially available LPWANs the market will be segmented and fractured.
Overview of LoRaWAN and Sigfox network:
Let’s look at the two most popular unlicensed band LPWANs:
- LoRaWAN is specified by the LoRa Alliance which includes 47 network operators.
- The LoRa Alliance states on its website: “LoRaWAN™ is the open global standard for secure, carrier-grade IoT LPWA connectivity. With a certification program to guarantee interoperability and the technical flexibility to address the multiple IoT applications be they static or mobile we believe that LoRaWAN can give all THINGS a global voice.”
- For the Physical layer (PHY), LoRa uses a modulation scheme called chirp spread spectrum (CSS) and a radio both developed and sold or licensed by Semtech Corporation.
- About two years ago, Semtech licensed its technology to Microchip and NXP (like ARM, Semtech now licenses to other semiconductor companies). As a result, the core LoRa hardware (PHY layer) is no longer provided by a single global chip manufacturer.
- LoRaWAN defines the media access control (MAC) sublayer of the Data Link layer, which is maintained by the LoRa Alliance. This distinction between LoRa and LoRaWAN is important because other companies (such as Link Labs) use a proprietary MAC sublayer on top of a LoRa chip to create a better performing, hybrid design (called Symphony Link by Link Labs).
- Many of the LoRa Alliance companies building products are focusing on software defined enhancement and use the LoRaWAN defined MAC.
- LoRaWAN will most likely be best used for “discrete” applications like smart buildings or campuses, where mobile network connectivity is not needed.
- Sigfox has designed its technology and network to meet the requirements of mass IoT applications; long device battery life-cycle, low device cost, low connectivity fee, high network capacity, and long range.
- Sigfox has the lowest cost radio modules(<$3, compared to ~$10 for LoRa, and $12 for NB-IoT).
- A recent announcement from Sigfox noted the addition of a new service called “Admiral Ivory,” that makes possible to connect devices with hardware components costing as little as $0.20.
- An overview of Sigfox’s network technology is described here. It consists of: Ultra Narrow Band radio modulation, a light weight protocol, small frame size/payload, and a star network architecture.
- The Sigfox network is currently deployed in 36 countries, 17 of which already have national coverage.
- In February, Sigfox reached an agreement with mobile network operator Telefonica to integrate Sigfox’s low-powered connectivity into the Telefonica’s managed connectivity platform. By complementing Telefónica’s cellular connectivity offerings, with Sigfox’s LPWAN connectivity solution, customers can choose the most appropriate type of connectivity or combine them, implementing use cases and creating new service opportunities that otherwise may not have been possible.
- Additionally, Telefónica´s managed connectivity platform will integrate Sigfox’s cloud, which gives the company the ability to develop its own end-to-end IoT solutions, based on Sigfox’s connectivity solution and including device integration, as well as data collection and management.
- While Sigfox is a proprietary IoT network architecture, the company has provided their intellectual property library free of charge and royalty-free to semiconductor companies which have implemented chipsets with dedicated Sigfox interfaces or multi-mode capabilities. The list of chipsets/modules supporting Sigfox (+ multimode) includes: Pycom (+ WiFi, BLE=BlueTooth Low Energy), Texas Instruments (+ BLE), STMicroelectronics (+ BLE), Microchip/Atmel, Analog Devices (+ BLE), NXP, OnSemiconductor (SiP), SiLabs, M2Com, GCT Semiconductor (+ BLE, CatM1, NB-IoT, EC-GSM, GPS), Innocom, and Wisol.
- The current Sigfox ecosystem is composed of several chipset vendors, device makers, platform providers and solution providers.

Sigfox’s LPWAN Interoperability using Internet Compression Technology:
In a phone conversation with Sigfox standardization expert Juan Carlos Zuniga last week, I learned that Sigfox plans to achieve LPWAN interoperability at the Application layer, rather than building multi-mode base stations with different radio access networks. Here’s a glimpse on how that might happen:
At the IETF 98 Bits-n-Bites event, March 30th in Chicago, Sigfox demonstrated IoT interoperability with internet compression technology. which enables LPWAN applications to run transparently over different IoT radio access network (RAN) technologies.
To achieve this milestone and enable IP applications to communicate over its network, Sigfox and Acklio implemented Static Context Header Compression (SCHC) -a compression scheme being standardized by the IETF IPv6 over LPWAN working group*, which Juan Carlos participates in. SCHC allows reducing IPv6/UDP/CoAP headers to just a few bytes, which can then be transported over LPWAN network small frame size for low-power, low-cost IoT applications.
* The focus of the IPv6 over LPWAN working group is on enabling IPv6 connectivity over four different Low-Power Wide-Area (LPWA) technologies: Sigfox, LoRa WAN, WI-SUN and NB-IOT (from 3GPP).
The demonstration platform was based on an Acklio compression protocol stack running on Sigfox-enabled devices and cloud-based applications over the live Sigfox network in Chicago. Two scenarios were demonstrated: 1] CoAP requests to legacy IP LPWAN devices, and 2] CoAP interoperability over the live Sigfox and cellular networks in Chicago with IP enabled endpoint devices.
“We are thrilled with this latest milestone in our quest to support and promote interoperability in the IoT,” said Juan-Carlos Zúñiga, senior standardization expert at Sigfox and co-chair of the IETF IntArea working group. “It is critical that the industry rallies together to adopt open internet standards to unlock the true potential of the IoT.”
Compression based technology for LPWAN application interoperability builds on Sigfox’s commitment to supporting the development of IoT interoperability as an active member of standards development organizations including the IETF, ETSI and IEEE 802. And the number of chip companies providing Sigfox network interfaces (see above list) is equally impressive.
Juan Carlos will be following up with a blog post on LPWAN application layer interoperability as well as a more detailed description of the IETF work on LPWANs.
