Rohde & Schwarz and Viavi support European OTIC in Berlin for O-RAN conformance certification for VVDN kit
The European Open Testing and Integration Centre (OTIC) in Berlin, supported by Rohde & Schwarz and Viavi, has awarded its firdst O-RAN conformance certification for international markets. The certification of an indoor O-RU of the LPRU-series from VVDN Technologies was completed according to O-RAN specified processes as defined by the O-RAN Alliance.
Indian contract manufacturer VVDN Technologies has developed its LPRU-series 5G NR Radio Units (O-RU) to be fully compliant to O-RAN ALLIANCE standards. The VVDN 4T/4R Split 7.2 radios are covering 5G NR TDD bands n77, N78 and n79. They are compact, lightweight, easy to install, and provide optimal coverage for indoor applications.
VVDN alsready has production ready radio units for Private 5G Network for multiple countries and markets. The company has both low power (4T4R 1W) and mid power (4T4R 20W) radio units suitable for private 5G deployments. VVDN’s radio units support global requirements in Band 48 CBRS, Band n78/n77 (3400 to 4100 MHz), and bandwidth up to 100Mhz, TDD duplex mode 4T4R and 2T2R for indoor and outdoor applications.
Last October the company, which also makes smartphones, announced plans to expand its manufacturing outside India although at the time founder and president Vivek Bansal would not be drawn on whether such a facility would be in the US, Middle East or Europe. Bansal hinted in an interview that Poland and Mexico were potentials. VVDN already has a small manufacturing presence in Fremont, California, to serve US customers.
Test mechanics
The O-RU verification followed the O-RAN fronthaul conformance test specification defined by O-RAN WG4, including the Control, User, and Synchronization plane (CUS-Plane) and the Management-plane (M-Plane). WG4’s objective is to deliver open fronthaul interfaces, in which interoperability between Distributed Unit (DU) and Radio Unit (RU) from multiple vendors can be realised.
The Berlin OTIC, one of four in Europe, is part of a publicly funded project called i14y Lab with its main facility hosted on premises at the Deutsche Telekom innovation campus. The others are located in Turin, Madrid and Paris, sponsored by TIM, Telefónica and Orange respectively. All approved Open Testing and Integration Centers (OTIC) worldwide cooperate with the O-RAN ALLIANCE in the O-RAN Certification and Badging Program, which represents a mechanism to ensure confidence in O-RAN solutions within the industry.
The i14y Lab is an open lab for interoperability testing of disaggregated telco systems, such as open RAN, led by Deutsche Telekom together with consortium partners. Rohde & Schwarz is one of the consortium members and offers an integrated solution for conformance testing of O-RAN Radio Units together with Viavi Solutions.
Both companies are active in specifications development in the O-RAN Alliance and have combined their capabilities: the solution consists of the Viavi TM500 O-RU Tester and the R&S SMBV100A vector signal generator (VSG), R&S FSVA3000 signal and spectrum analyser and Vector Signal Explorer (R&S VSE) software from Viavi TM500, with the O-RU Test Manager from Viavi as single point of control, providing a seamless user experience.

NRB acquired 20MHz in the 3600MHz band to offer 5G directly to its customers but has now decided to embrace the MVNO model
Belgium’s former incumbent, Proximus, it looking to acquire more 5G spectrum from NRB in the 3600MHz range. Proximus says the acquisition will support its “ambition to continue to offer the best mobile experience in Belgium for decades to come”.
NRB is selling its 5G licence to refocus on its core business, while maintaining its commitment to offering 5G services. The companies are discussing a possible wholesale agreement.
The NRB Group is one of the biggest ICT firms in the country and serves public and private sectors organisations in Europe. In 2022, it had revenues of €505.4 million and more than 3,450 employees.
Spectrum auction in 2022
When the 5G spectrum was auctioned in the summer of 2022, Proximus decided to invest €600 million over 20 years.
At the same auction, NRB acquired 20 MHz in the 3600MHz frequency band to provide 5G services to customers in the public and social sector, industry and biotech, energy and public utilities, financial organisations and insurance companies.
Now the Belgian company has decided against rolling out its own mobile network, but intends to continue offering 5G services to customers as an MVNO – possibly through a partnership with Proximus.
Raising the limit
Acquiring the additional 20 MHz in the 3600 MHz band would give Proximus a total of 120 MHz so that the operator could add more capacity where needed. In future, it could be used to improve throughput and latency, as well as the security of data flows on private mobile networks.
The agreement between Proximus and NRB was submitted to the BIPT, the federal telecoms regulator. The latter has approved the transaction, subject to the effective transfer of rights taking place after the publication of a new call for applications for the 3410-3430 MHz band in the Belgian Official Journal.
That publication is imminent and the call for applications will be accompanied by an increase in the spectrum cap from 100MHz to 120 MHz to enable Proximus to acquire NRB’s 20 MHz.
SaaS provider Totogi claims total cost of ownership could fall by up to 80% as disaster recovery expenses are all but eliminated
Totogi’s Charging-as-a-Service platform has gone live for Zain Sudan which has more than more than 20 million subscribers. The country has a population of just over 49 million. According to the SaaS provider, the transition from the legacy charging system to the new platform took 18 days for Zain’s production and disaster recovery environments.
The expected benefits are up to 80% lower total cost of ownership (TCO). Totogi says the new platform has “nearly eliminated Zain’s disaster recovery expenses, slashing them to just a fraction of the previous cost of maintaining a backup service”.
Sudan has been ravaged by civil war between the country’s army and the paramilitary Rapid Support Forces (RSF) since April 2023 and it appears to be intensifying.
Totogi bills Zain on a pay-as-you-grow’ business basis and says this also allows the operator to scale as required while avoiding large upfront costs.
Totogi also claims that the cloud-native solution has “future-proofed” Zain’s BSS stack and offers better performance, reliance and compliance
Emad Elsheikh, CTO at Zain Sudan, commented, “Transitioning over 20 million subscribers to Totogi’s platform was executed with remarkable speed and efficiency, showcasing the agility and effectiveness of their solution in managing large-scale subscriber bases under demanding conditions, particularly in times of crisis when traditional on-prem systems are likely to fail”.
Zain Sudan is part of the Zain Group, which offers mobile voice and data services and started in Kuwait in 1983. It has opcos in seven Middle Eastern and African countries, providing services to more than 50.6 million individual and business customers as of the end of last year.
Despite a 19% drop in sales, Pekka Lundmark remains confident of a stronger second half and achieving the company’s full year outlook
Nokia CEO and president Pekka Lundmark reflected on what the company called a “challenging environment” after weaker sales in North America and India led to the vendor posting revenues of €4.67bn, down by almost one-fifth from a year ago.
However, big cost cuts – including October’s announcement it would cut up to 14,000 jobs out of 86,000 employees – meant the vendor ending up with a 52% rise in Q1 net profit (€438m). Gross margin improved significantly year-on-year, to 48.6%, due to a combination of an improved gross margin in Mobile Networks, and the three smartphone licensing deals signed in Nokia Technologies. The vendor ended the quarter with a net cash balance of €5.1 billion.
Like Ericsson earlier in the week, Lundmark has seen some second-half green-shoots stating: “continued improvement in order intake, meaning we remain confident in a stronger second half and achieving our full year outlook.”
Breaking this down, Nokia saw improved order intake trends in its Network Infrastructure business in Q1 – the book-to-bill ratios was above one. Lundmark said the outlook for Fixed Networks has improved over the past three months, adding it was usually the first market to recover. However Optical Networks was still looking weaker. As a result, he sees Network Infrastructure returning to growth in the full year.
In Mobile Networks, the end of the 5G growth spurt in India combined with ongoing low levels of activity in North America led to a 37% net sales decline in the quarter. Nokia said that while all regions remained weak it continued to see growth in Middle East and Africa.
Fixed line’s relative health
Lundmark said Nokia has more than 40% market share globally excluding China in OLT products. “With our product portfolio and the ability to offer customers a roadmap to deploy X GPON, XGS-PON, and 25G PON in the same line card, we have a compelling value proposition,” he said. “Customers can also upgrade to 50G and 100G in the same chassis down the line with our Lightspan MF-14 platform.”
He added: “It’s important to remember that globally excluding China over 70% of homes are still not connected by fibre and there is a significant opportunity remaining in our biggest markets of both North America and Europe… In Europe, we see deployments remaining at a high level in markets with low penetration and we are seeing some mature markets starting to upgrade to XGS-PON and 25G PON.”
Automation and reducing telco opex
The chief executive said Nokia now has the capability to drive zero-touch autonomous operations across all network domains, including managing autonomous operations across multi-vendor networks.
“We have customers who are purchasing our autonomous operations specifically to accelerate their API exposure strategy,” he said “Our holistic solution is what also enables network programmability and the ability for CSPs to expose their APIs to developers using our network as code platform. This is a key point and we already have 11 operator agreements for our platform.”
He added: “To fully benefit from the emerging network APIs, CSPs need their operations to be fully automated because the API paradigm assumes an application interacts directly with the network in real time.”
Dell partnership is strategic
Lundmark highlighted Nokia’s strategic partnership with Dell, announced at MWC, as something that will benefit the vendor’s mobile, cloud and network offerings. “On the Nokia side, we will now adopt Dell as our preferred infrastructure partner for existing Nokia AirFrame customers, which will enable us to refocus our R&D efforts into areas where we can really differentiate as Nokia,” he said.
“Secondly, our private wireless solution, NDAC, or Nokia Digital Automation Cloud, will become Dell’s preferred private wireless platform for enterprise customers,” he said. “And we can see this becoming a very powerful channel to further drive growth in private wireless.”
Displacing Huawei and replacing chips in China
The CEO told analysts that the move by operators to strip out Huawei equipment was a gradual process. “But in typical Chinese vendors account 20% to 30% in markets outside of China, outside of the US of course, we estimate that last year in Mobile Networks and network infrastructure, the Chinese vendors have roughly or had roughly €12 billion in sales outside of China,” he said.
“And about half which is €6 billion of that in Europe, and this is obviously an ongoing discussion in several European countries that how they should deal with that question. But gradually the importance of this opportunity for us is continuing to grow,” he added.
When asked about the recent Chinese Government stripping out foreign chips from the nation’s telecom equipment, Lundmark said Nokia had not seen any impact. “We still need more clarity around that statement, because there are so-called foreign chips in pretty much all parts of all networks,” he said. “So, it’s very hard to see what that would mean in practice. So, we need more clarity about that. But important for us is to of course remember that our market share in China is fairly low and China accounts only – Mainland, China accounts for a low single-digit percentage of our sales.”
Sunrise filed a complaint against Swisscom suggesting the telco had behaved improperly in the 2008 tender process to set up a broadband network at Swiss Post sites
Switzerland’s Federal Supreme Court has concluded that Swisscom’s conduct in the 2008 tendering process for the broadband networking of Swiss Post sites was fair. As a result of the decision in the long-running legal proceedings, last month the court upheld Swisscom’s appeal and overturned the original penalty decision of the Competition Commission (COMCO) from 2015, with the imposed fine of more than CHF 7 million, as well as a Federal Administrative Court judgement from 2021.
Swisscom welcomed the Federal Supreme Court’s ruling which also overturned the contested ruling of the Federal Administrative Court, which in 2021 concluded that the telco “behaved improperly” in the 2008 tender process to set up a broadband network at Swiss Post sites.
The Federal Supreme Court found that Swisscom did not force unreasonable prices on Sunrise or Swiss Post and demonstrated fair conduct in the setting of prices for wholesale products. Moreover, the prices charged by Swisscom for these wholesale products were not inflated.
In respect of Swiss Post, the Federal Supreme Court found that the bid price was the result of negotiations and was not set unilaterally by Swisscom. Finally, the court concluded that Swisscom had not imposed a margin squeeze on Sunrise and did not demonstrate anti-competitive conduct.
Long-running dispute
The proceedings date back to 2008 when Swiss Post had put out a call for tender to set up a broadband WAN between its sites. After a suitability test, it requested bids from Sunrise, UPC and Swisscom. It then accepted Swisscom’s bid in January 2009. Sunrise responded by filing a complaint against Swisscom with the competition authority, claiming that Swisscom had violated the Federal Cartel Act.
In September 2015, COMCO concluded that Swisscom had abused its market position, forced unreasonable prices from competitors and Swiss Post, and imposed a margin squeeze. In response, COMCO imposed a fine of CHF 7.9 million on Swisscom.
Swisscom contested COMCO’s decision
Swisscom said it had previously demonstrated to COMCO that Sunrise would have been able to submit a competitive bid if it had made “prudent use of its own and intermediate inputs”. The telco said in a statement: “The allegation of misconduct to the detriment of Swiss Post is also incomprehensible: as a powerful buyer, it had awarded the contract to the party submitting the most competitive bid, from its perspective, within the context of a GATT/WTO tendering process and in accordance with the strict rules that such a process entails.”
Swisscom subsequently lodged an appeal against the COMCO decision with the Federal Administrative Court. In June 2021, the Federal Administrative Court largely upheld the COMCO decision, but reduced the fine imposed to CHF 7.4 million. The Federal Administrative Court also concluded that Swisscom had behaved unlawfully in the tender for the broadband networking of postal sites to the detriment of Sunrise and Swiss Post.
Swisscom lodged an appeal with the Swiss Federal Supreme Court stating that it acted in accordance with the law during the tender process launched by Swiss Post, which requested bids from Swisscom and Sunrise.
Salty ending
In February, Swiss Post signed a strategic partnership with Salt to offer prepaid and postpaid “Post Mobile” services from its branches. Despite offering subscriptions, smartphones and telecom accessories from various providers in its branches for more than 20 years, Swiss Post has moved to a single partner. However, Swiss Post is still tied to Swisscom for several ICT services.
UK operator to use Starlink to reach underserved rural areas; IoT provider to offer fully managed combo of cellular and satellite connectivity to expand reach
Virgin Media O2 is using Starlink’s Low Earth Orbit (LEO) satellite technology to provide mobile backhaul for some of the country’s most remote locations to accelerate its Shared Rural Network (SRN) rollout.
The operator has deployed the Starlink for backhaul in the Scottish Highlands (pictured) which are difficult or impossible to connect using technologies like fibre or microwave connections.
Implementing satellite connections to these locations is after intensive testing and a successful recent trial in northern Scotland.
SRN behind schedule
This is the latest development in Virgin Media O2’s push to improve mobile signal in rural communities through the Shared Rural Network programme. With the exception of EE, the participants in the SRN are behind targets, according to the National Audit Office. Last October, Vodafone, Three and Virgin Media O2 reportedly asked the government for up to two more years to complete the first stage of the Shared Rural Network (SRN)
Virgin Media O2 is also exploring satellite connectivity for emergency services and to boost mobile connectivity at large events.
This Starlink project was delivered in collaboration with Telefónica Global Services (TGS). TGS is a subsidiary of Telefonica Group, which owns 50% of Virgin Media O2, and is an accredited Starlink reseller.
Jeanie York, Chief Technology Officer at Virgin Media O2, said, “By constantly finding new ways to deliver for our customers, we are bringing reliable mobile coverage to rural communities faster and helping to close the UK’s digital divide.”
Starlink and global IoT
Wireless Logic, a global IoT connectivity platform provider, has secured authorised reseller status for SpaceX’s Starlink LEO satellites. The agreement meansWireless Logic will integrated satellite connectivity into it portfolio of managed services. The rationale is to offer customers greater flexibility and choice for their global IoT deployments.
Wireless Logic’s specialist subsidiary Blue Wireless will deliver integrated, managed services combining LEO technology, LTE and 5G. It will offer data plans, installation and on-site support in more than 70 countries worldwide, with guaranteed service level agreements regarding uptime and speed.
Wireless Logic acquired Blue Wireless last year to strengthen its presence across the Asia-Pacific region and the Americas, as well as improving its fixed wireless access portfolio.
Unique proposition for industries
Oliver Tucker, CEO at Wireless Logic. “This milestone agreement underlines our commitment to innovation. While cellular remains a cornerstone for many applications, the addition of satellite connectivity is a game-changer – especially in challenging cross-border environments and areas of weak coverage.
Ivan Landen, CEO at Blue Wireless, said of the Starlink arrangement, “By harnessing the combined strength of 5G/LTE and satellite technologies, we can deliver a unique proposition for industries like energy, agriculture, mining, construction and maritime. This extends to other organisations needing resilient branch, portable or mobile connectivity.
“Our Global Managed LEO proposition helps global customers overcome typical challenges like procurement, installation, support and in-life performance.”
The operator panellists shared their candid experiences around how their service delivery and cultures are changing to stay competitive, internally and through partnerships
The discussion took place at our recent Telecom Europe Telco to Techco virtual event, moderated by CCS Insight consumer and connectivity director Kester Mann. Our panellists were Telefónica Germany VP director of massmarket Dr Mariam Kaynia, Vodafone Business head of digital Michelle Hastings and Intellias senior director telecom & media Ahmed Soliman.
Intellias’s Soliman said the adoption of current tools and open-source technology is vital for telcos to innovate and stay competitive. Despite the industry’s regulation constraints, integrating open-source solutions like OpenAI offers opportunities for advancement. Soliman also addressed the disparity in talent acquisition and flexibility between telcos and technology firms like hyperscalers. While the latter can readily acquire talent and pivot with ease, telcos face challenges in upskilling their workforce and adapting to rapid changes.
He underscored the importance of investment strategies, noting how technology companies have historically been quicker to identify and acquire innovative platforms like Skype and WhatsApp, revolutionising communication.
Hyperscaler competition has changed
Telefónica’s Kaynia agreed that telcos are slower than hyperscalers at this, but she said: “it’s simply because of our legacy landscape that makes it hard to adapt as fast as some of the others do.”
She also addressed the evolving relationship between telcos and hyperscalers in tackling enterprise networking requirements. Emphasising a spirit of partnership over competition, she highlighted the necessity of collaboration to meet the demands of a rapidly changing market.
“It’s not about comparing [to hyperscalers]. It’s a partnership that is required and this is how we also operate in the industry,” she said. “We are not competing, we are not trying to say take each other’s lunches, we actually need each other in order to be able to become more digital and more efficient and more agile towards our customers as a whole.”
Kaynia acknowledged the unique capabilities that hyperscalers bring to the table, emphasizing a desire to leverage these without duplicating efforts internally. Conversely, telcos offer expertise and established customer relationships that are invaluable in delivering comprehensive solutions.
“It’s really more about a hybrid collaboration across the whole system to bring together the different players need from cloud providers…solution providers…telcos…system integrators and only jointly can we really deliver what the market needs,” she said.
Addressing the complexities of the current landscape, she attributed much of the challenge to the rapid evolution of customer demands alongside the need for telcos to manage both stagnant revenues and increasing costs. “If you put the whole landscape together, it is more complex because you want to deliver more you want to do much more for our customers and be more agile and efficient and, at the same time, we need to manage the both revenue as well as the cost side of it,” she said.
Vodafone’s Hastings agreed that it is becoming increasingly clear what each party now brings to the table to get the right outcomes for customers. But first you need to understand what the customer wants. Do they need more oxygen in the P&L, are they reducing costs, have they spotted a business opportunity, is their IT estate too complex? “Depending on what’s driving that behaviour will ultimately depend on the right answer and whether that is to partner with a telco directly or whether that’s to use an integration partner instead,” she said.
She added that AI is changing this equation once again with customers asking “where am i going to be using that AI, where’s my data…I think [the issue is] starting to understand some of those questions to then be able to make the right decisions about who do I partner with who’s going to help me to fill perhaps the gaps in knowledge that I might have, or the gaps that I might have around my IT estate.”
Data leverage example
Soliman gave the example how telco marketing teams can benefit when vast amounts of network data and customer data are abstracted to deliver insights and develop new services. “You have the [customer] data, you have coverage heat maps, you have the status of the devices so how can I abstract this to [help] marketing promote new products and services,” he said, adding that new tools like GenAI help with this.
Marketing should be able to ask a simple question in layman terms and this massive, complex database that telcos have, with all its data points, should be able to give them actionable insights liking where to launch a service in their footprint.
Do telcos have the right culture?
Telefónica’s Kaynia said implementing cloudification and microservice architecture is not an easy task but the operator is doing this to be more efficient so it can have independently deployable components or features – the exact principle behind agile DevOps. “We cannot survive with this this,” she said. “If you’re not agile enough, it means we are not fast enough to adapt.”
And this impacts culture. “If we are not fast enough to be able to launch something deploy it independently with CI/CD and DevOps, [then] we can’t even get fast enough feedback to be able to adopt and then be able to calibrate as per our customers’ needs, which means we will be holding either ourselves back or the market back,” she said. “I see it as a fundamental enabler to have that right culture to move to the agile ways of working; to move towards DevOps, in order to achieve everything we talked about in terms of digitalisation and higher speed.”
Vodafone’s shift in core competencies
Hastings said she had seen “a real shift” at Vodafone in “bringing some of our core competencies and core capabilities back in house and being quite selective about where we do partner.” As a result, the telco is in the process of creating significant development and engineering hubs.
“When we think about things like digital transformation, but then really importantly, data transformation and look at where we have the skills where we need the talent and then marry that to culture, you start to kind of touch on quite an important dynamic between those two things,” she said, highlighting the intricate relationship between skill sets and cultural values.
Hastings underscored the significance of fostering a culture that empowers individuals to take ownership and initiative, stressing the importance of attracting and retaining talent within the organisation. “I think having the right environment to attract talent, to fill the right skills to then enable them to ultimately be successful. And ultimately help all of us to progress,” she said, emphasizing the role of a conducive environment in nurturing talent and driving collective advancement.
Acknowledging the ongoing evolution of organisational culture, she added: “Have we gotten it 100% right yet? No, I doubt any company…I hope no company would ever say that they do. Right? Because culture is always evolving, right? It’s always improving. There is always something that we can do better.”
The Hungarian operator, which has a controlling share of Vodafone in-country, says so-called 5.5G is capable of up to 10 times faster download speeds than 5G
Central European operator 4iG has successfully demonstrated the potential of the 6GHz band and 5G Advanced technology – which was only included by the ITU as licensable spectrum at WRC23 the end of last year – in the Budapest University of Technology and Economics (BME VIK) laboratory.
The telco, together with the Faculty of Electrical Engineering and Informatics of the Budapest University of Technology and Economics, is researching cutting-edge technology and said the new antenna technology based on current base stations, can offer up to ten times the download speed compared to the fastest 3.5 GHz solution currently in use.
With measurements carried out under laboratory conditions, the working group consisting of 4iG Group engineers and BME VIK researchers registered a data transmission speed of more than 10Gbps. The operator said a significant advantage of the new, so-called Extra Large Antenna Array (ELAA) antenna technology is that the 6GHz band can also be installed at existing sites and base stations to expand the network capacity “by leaps and bounds”, adapting to the 3.5 GHz coverage, new base station without installing locations.
Huawei solution
The solution ran on Huawei Technologies devices, and the operator said by using it, mid-band frequencies are capable of gigabit data transfer speeds with wider coverage. The equipment installed at the Budapest University of Technology and Economics primarily serves research purposes and, with the cooperation of 4iG’s Western Balkan subsidiaries, the test period also provides the researchers of the technical universities of Tirana and Podgorica with the opportunity to learn about and study the new technology.
Six months ago, 4iG Group chairman Gellért Jászai and Group CEO Peter Fekete signed an MoU in China with Huawei chairman Liang Hua to collaborate on 5G, despite the EU’s decision to impose security restrictions on the use of 5G equipment from “high-risk suppliers”. US Government officials subsequently met with Jászai and reportedly expressed their concerns about Huawei.
4iG Group became the majority owner of Vodafone Hungary at the beginning of last year. The telco is currently amidst the handover process of Vodafone’s technical and administrative back-end systems. In July last year, as part of a wider mobile network portfolio rejig, 4iG Group subsidiary Antenna Hungária entered into an agreement to sell MIS Omega Mobilhálózat, which owned Digi’s mobile infrastructure in the country. The new owner, state-owned Pro-M, gained 2,500 towers, active and passive radio network assets, as well as the rights and 1800MHz spectrum licences.
The path from trial to reality
“The testing of the world-first 6GHz mobile technology is in line with the 4iG Group’s innovation plans and digitalisation goals,” said 4iG Group’s mobile and 5G strategy director Pál Zarándy. “The switch to 5G technology is an entry point for 4iG, which has a strong IT background, because in addition to providing the infrastructural background, it also enables the exploitation of the most modern data transmission solutions.”
“The 4iG Group has brought the next level of mobile communication development to Hungary and Central-Eastern Europe, the 6GHz 5.5G cutting-edge technology,” he added.
“The 6GHz technology just presented is an important step in terms of the goals previously formulated in the 5G visions,” said BME VIK dean of the Faculty of Electrical Engineering and Informatics Dr Charaf Hassan. “The new frequency band accepted by the ITU helps the development of advanced, 5G-based industrial applications, the creation of smart factories and a ‘connected’ economy.”
He added: “The 6GHz radio data transmission arrangement is only an experimental demonstration. At the same time, the events of this year’s Mobile World Congress (Barcelona) and the increased industrial interest in the new technology indicate that 6GHz may soon appear in mobile networks and gigabit mobile internet will become a reality for users.”
Philippe Ensarguet’s keynote at Mobile Europe’s recent Telco to techco virtual conference was all about how telcos’ can return to growth in conversation with Annie Turner
Philip Ensarguet is a former winner of Mobile Europe’s CTO of the Year in the Trailblazer category (he then held that role at what is now Orange Business). With “a 100% software background” he is now VP of Software Engineering reporting directly to Orange’s group CTO, Laurent Leboucher. His job is both to be a strategist and an implementer, and his job recently has been “working hard on how to manage and orchestrate the new generation of telco cloud infrastructure, and telecoms shift towards cloud native and becoming a cloud-native telco”.
As a strategic thinker, he contributed to NGNM’s cloud-native manifesto and to the Cloud Native Computing Foundation’s white paper, which specifies, in great depth, telcos’ requirements to move towards being cloud nativeEnsarguet says that In his regular meetings with analysts and vendors, he finds “they are using one or the other of [those documents] as kind of backbone or map, to explain how they are working to transform themselves to meet those needs”.
He adds, “The relationship with the vendor ecosystem is super interesting because there are a lot of things to support in terms of transformation. The delivery of best practices in software, APIs and automation, for example, is far behind what we had when I was purely [working] in digital. That’s why it’s so exciting.”
The session was designed to probe why so much work has gone into telcos’ transforming themselves and continues, yet it is not reflected in new revenues or share price. So how will network’s ongoing evolution and operational transformation lead to growth? In short by a radical change in how telcos’ infrastructure, implementation and operations…
The following is an edited version of Ensarguet’s answers to the editor’s questions, for brevity and sense.
Ensarguet explains, “To be concrete on this, I want to emphasise that by definition, for instance, a 3GPP functional specification rule how [certain] network services have to work. But all the wrapping and the lifecycle around that is going to change based, for instance, on automated infrastructure, a new generation of deployment strategy, new ways of operation that are opening doors for novel, more optimised operating models.
Ensarguet said he’s not concerned that in the past so much talk was about telcos being behind Big Tech in terms of digitalisation because “it means that we can really learn and grab the best practices that enable or fast track digital and [associated] tools into the telecom ecosystem.”
He believes the big levers regarding growth are: API-isation, automation, the move from a vertical model to a horizontal one and AI – and especially generative AI. The four things are not separate, rather they impact each other. Ensarguet also thinks there are also some topics outside the ‘pure’ telco world that could have a big influence regarding opportunities for growth.
Underlay and overlay
Orange is concentrating on how best to use APIs to leverage the value from the underlay and the overlay networks to differentiate services – a huge benefit of owning the network. He notes there is a big industry focus on CAMARA, the Linux Foundation’s open-source project, including the definition of a new network API that can do two things. Firstly, retrieve information from the network and secondly configure the network.
He acknowledges that with the GSMA’s Open Gateway initiative, the emphasis has largely been on leveraging APIs for mobile connectivity, but says in the context of 5G, both fixed and mobile need to benefit from APIs. Ensarguet comments, “It’s not an option if you want to fully support the promise of what we are calling the programmable network”.
There has been some progress already on the fixed side, he says, such as “the old device policy on-demand or the CPE”. He adds that, “For standardisation, we work to establish end-to-end connectivity, for both. And it’s happening also in the open-source ecosystem. We truly believe that it will definitely help to create the API that has the most impact for the developer communities.”
So there is considerable effort in addressing the APIs in the right order. He says the industry wants to be sure that “We are prioritising the network services that would help B2B or B2B2C company to implement the cases where the API and network could bring a new superpower”.
Orange demo’d three kinds of use cases at Mobile World Congress, with Ensarguet stressing this is just one year after the launch of CAMARA:
• smooth, verified onboarding of users using their digital ID using two APIs from Orange’s production network
• location verification – using face recognition for secure payments between two people and being able to prove that the devices are at the same location. He says, “Here the network is bringing a superpower” combining its less exact location info with their GPS location
• geofencing – ID is used to provide notifications when devices enter a given area.
He says their potential is huge and highlights a Spanish company that is working on preventing gender violence. Ensarguet’s point is that it is not the APIs per se that matter, but the uses to which they are put.
Asked about the progress of network automation, he stresses, “We need to understand that the automation is mainly done with the network function technology we are using. You can automate physical network, you can automate the virtual network you can add to an automated network, but the level of the workload you are manipulating here as absolutely different…and that’s why we engage so much with this cloud-native, horizontal model transformation.”
He adds, “Extended delivery of automation and moving to the autonomous network for us is critical because it’s about saving money on operation and bringing us much more efficient operations. And here of course is where generative AI has a super-disrupting potential.
Industrial model
“We are investing a lot into what we are terming our industrial model to support the transformation from the flows and vertical silos to the horizontal one,” he says. “The idea is to push for an infrastructure, a deployment strategy and operation that’s API-driven and the others things I [am sharing].”
He explains, “We are pushing the level of the intent at a scale, where…our infrastructure is for the cloud native purpose is 100% intent-based and using the GitOps model [so] we are spinning our infrastructure in pure software.”
This approach to achieving a highly strategic foundation for infrastructure rests on the Sylva open-source project whose aim is to “an open Telco Cloud platform of reference” on which automation sits.
Ensarguet adds, “We are adding what we call the network integration factory, that is a total critical assets. The idea is that instead of relying on very specific and proprietary deployment, and lifecycle management tools, we rely on something we build that’s 100% standardised and we leverage the best practices from the digital and the IT world. Today, the network integration factory tooling zone is just a cloud native application we are deploying in our Orange central cloud…[that can]…provide the detailed framework for all the tools for deployment, lifecycle management and continuous testing.
“For us it is critical to be sure that everything has been validated before moving to production or accurate when the deployment is done. Everything about this is moving up to the operation layer and a new way operation that’s much more closer to the digital and IT.”
He continues, “A large part of this automation is thanks to the cloud-native superpower…it’s about the abilities in terms of resilience, of closed loop reconciliation, and risk management. Being able to rely on an orchestrator with such capabilities is a total game changer in the way we can automate and remediate our infrastructure.”
Growth is an ecosystem shift
A great question from the audience was, “How do you maintain the network advantage against competition from systems integrators and hyperscalers while transforming to a telco? Would you go as far as one of your competitors [T-Mobile USA] and [claim to] be an uncarrier?
Ensarguet said the first thing to stress is that integrators and hyperscalers are very important partners as well as competitors. The new, simple API business is leveraging use cases…but you can only have these benefits if you own the network. For me, that is a true differentiator.”
He concludes, “The four components [outlined above] can enable a new business model or new way of building infrastructure or consuming the services. For me [hyperscalers and integrators], are more enablers than real competitors… That’s why the industrial model we are working on right now around the infra layer, implement layer, operation layer is so important. It’s where we want to standardise and apply to mutualisation. It’s what I’m observing with our every telco peer.
“As a final thought, last Monday Orange had a cloud-native workshop where we add up to six or seven telco peers, from Europe and Asia. Basically, they told more or less the same story about the business of transversality is need of regionalisation is needed of some data. And that’s why all the same telcos are working hand-in-hand, supporting the transformation of the ecosystem because here in the new domain for a growth – new ways of implementation.
“We cannot win alone. We need the whole ecosystem. That’s why it’s so important to support the integrators, the vendors, the hardware makers, because we can only win growth for the new generation if the whole ecosystem is shifting.”
Technology, operations and management kept under one umbrella so customers don’t need to worry about platforms, operations, analytics, and reporting
Deutsche Telekom Global Carrier has introduced Magenta Security Roaming which it said offers an ecosystem of secure connectivity for all protocols currently used by its customers: 2G, 3G, 4G, 5G non-standalone (NSA) and 5G standalone (SA). For each protocol, corresponding protection layers are in place which work in unison: SS7 Firewall, Diameter Edge Agent (DEA) Firewall, Diameter End-to-End Signalling Security (DESS), phase 1, as well as Security Edge Protection Proxy (SEPP) in several configurations.
The service is available to all the wholesaler’s customers, both its own group national operator companies (NatCos), as well as operators across the globe. The new concept comprehensively addresses operators’ increasing need for low-latency, reliability and security when roaming in today’s interconnected world.
Deutsche Telekom Global Carrier provides all Magenta Security Roaming services with dedicated support and SLAs. The service is designed to help maintain business by increasing the quality of operators’ cyber-defence systems, while reducing cost and complexity, according to the operator. As roaming security will become increasingly heterogenous throughout the world, Magenta Security Roaming offers a way to connect each destination with the top security as required by both operators.
5G SA roaming
For those operators which have already enabled 5G SA roaming, Magenta Security Roaming guarantees that they have options when interconnecting with each other by choosing the security measures they need. Telcos can outsource investment and operation of 5G SA roaming with Magenta Security Roaming’s outsourced SEPP solutions.
They can also opt for hosted SEPP maintenance services, as well as “composite scenarios” that connect individual roaming partners most efficiently. These include Deutsche Telekom Global Carrier’s new Group hosted SEPP for Family & Friends services specifically dedicated to its internal (NatCos) and external operator customers.
Deutsche Telekom Global Carrier claims it is the only carrier to offer DESS, phase 1 for 4G and 5G NSA services, which guarantees end-to-end authentication of signalling messages. “The combination of Diameter Firewall and DESS, phase 1 enables the world’s most secure LTE and 5G NSA exchange between mobile operators,” stated the telco.
“Security in roaming is a major issue in our industry. For the first time, we work with 5G SA as a technology where security is built in, while we still have to protect all the other protocols effectively to ensure roaming security across the board,” said Deutsche Telekom Global Carrier VP voice and mobile solutions Nicholas Nikrouyan.
“Magenta Security Roaming is our answer to this all-or-nothing scenario with highly innovative roaming security services, as well as our world-exclusive offer of DESS, phase 1,” he said. “Our innovative roaming concept allows us to avoid 5G hubbing and move to a world where security is there by design.”
First hosted SEPP 5G SA roaming
Last October, T-Mobile US and Deutsche Telekom Global Carrier completed successful testing of 5G Standalone (5G SA) roaming, utilising the wholesaler’s Security Edge Protection Proxy (SEPP) to complete the world’s first hosted SEPP 5G SA roaming T-Mobile US and Sunrise and a direct SEPP to SEPP interconnect with AIS Thailand.
The program used Deutsche Telekom Global Carrier’s Internet Protocol Exchange (IPX) and Hosted Security Edge Protection Proxy (SEPP) solutions with Sunrise and AIS, successfully completing 5G SA roaming between the US and Switzerland and the US and Thailand.
The telco said 5G SA roaming networks will offer faster speeds, lower latency, and higher capacity compared to non-standalone (NSA) networks. SA roaming is also crucial for supporting massive IoT deployments and critical IoT applications.
