Deutsche Telekom Achieves End-to-end Data Call on Converged Access using WWC standards

Wireline and wireless services are delivered today from two distinct technology implementations with separate network cores. 5G WWC standards offer a path to a fully converged broadband access network that integrates wireless and wireline operations on a common 5G Core.

Using these 5G Wireless Wireline Convergence (WWC) standards [1.] in an industry first proof-of-concept, Deutsche Telekom has validated in a lab trial the feasibility of converging the fixed network control plane into a 5G Core to steer traffic from a 5G residential gateway in its Bonn laboratory. The traffic was then routed along the entire wireline access chain to the core network.

Note 1.  The GSMA’s 3rd Generation Partnership Project (3GPP), the Broadband Forum (BBF) and CableLabs have united to create technical reports and specifications defining the services and systems required to support 5G wireless and wireline convergence (5G WWC) architectures. Their resulting work is detailed within BBF’s TR-456 (Fixed Mobile Convergence / FMC) and CableLabs WR-TR-5WWC-ARCH and rolled-up within 3GPP Release 16 Technical Specification TS 23.316. The IETF have also been engaged in providing guidance around user plane protocol revisions while the IEEE, ITU-T SG15 and Metro Ethernet Forum (MEF) have been engaged with timing/synchronization requirements and other service specifications.

The Access Gateway Function (AGF) supporting wireless wireline convergence in a 5G Core

“Convergence will allow us to optimize our network assets and deliver new, differentiated service experiences to our customers regardless of the access used,” says Ahmed Hafez, VP Network Convergence, Deutsche Telekom. „Our tests prove the feasibility of the convergence architecture by controlling residential gateways in our fixed network from a common 5G Core.
It is critical now that the vendor ecosystem implements the standards into their product roadmaps, speeding up the time to market for end-to-end convergent solutions.”

The proof of concept was conducted on a trial system in Deutsche Telekom’s lab environment. For the 5G residential gateway, which provides the connection between the networked equipment within a home or small office to the 5G Core, a Deutsche Telekom developed prototype was used.

5G Core as common core:

Operators traditionally use two separate and distinct network cores: one for wireless users and one for wireline access. The 5G Core can be implemented as a common core, where the control plane and user plane can span across wireless and wireline networks. Therefore, the new converged network based on 5G WWC standards enables operators to support both wireline and wireless networks without unnecessary duplication of functions such as authentication, subscriber databases, charging, and network-management tools. It also creates new options for converged services.The trial system takes advantage of 5G User Plane Function (UPF) and Access Gateway Function (AGF) from Casa Systems. Casa’s cloud-native 5G Core network functions provide multi-access support independent of network access type. And the 5G residential gateway prototype, which is internally developed at Deutsche Telekom, connects over the wireline access network.

The AGF mediates between the wireline access network and the 5G Core, with mapping between wireline broadband and 5G authentication, authorization, and session establishment procedures.

Deutsche Telekom CEO receives another towers deal offer

Deutsche Telekom (DT) has reportedly received another €20 billion (US$21 billion) offer for its telecom towers business, this time from a consortium of three private equity firms – KKRGlobal Infrastructure Partners (GIP) and Stonepeak Partners – according to Bloomberg.

Cellnex has previously confirmed it is bidding for DT’s towers business, with reports suggesting it has teamed up with Brookfield Asset Management to make an offer. And others are interested too, with Bloomberg reporting that Vodafone-owned Vantage Towers could emerge as a bidder, either on its own or with a partner, as could DigitalBridge. DT has been seeking some kind of deal for quite a while, with the German operator’s CEO Tim Hoettges issuing a very clear invite to all interested parties in November last year: At the time, Cellnex, Vantage Towers and Orange’s towers unit, Totem, looked like the leading candidates in terms of being a good industrial fit.

Talking about DT’s tower assets during the online Morgan Stanley European Technology, Media and Telecoms conference on Thursday, CEO Hoettges said he would “love to have an industrial partner and I’m willing to deconsolidate,” reported Reuters, though DT would need strategic influence in any joint venture, particularly related to any future M&A activity.  “I prefer an industrial solution, but I always need two to tango… I’m open for partners,” added the CEO.

Europe’s struggling telecom carriers once saw ownership of these network infrastructure assets as a vital part of their business models. Now, under pressure to raise cash and cut the bill for new network investments, they’ve begun to spin off their wireless masts into separate units or sell them outright.

Private equity firms are drawn to telecoms infrastructure because of its ability to generate steady, long-term returns. KKR raised $17 billion for its latest global infrastructure fund earlier this year, while GIP is targeting $25 billion for what would be the world’s biggest pool of capital dedicated to infrastructure investments.

Cellnex, Europe’s biggest mast operator, already jointly owns towers with Deutsche Telekom in Switzerland and the Netherlands. Germany is the only major European market where Cellnex hasn’t been able to build a presence.

Deutsche Telekom demos end to end network slicing; plans ‘multivendor’ open RAN launch in 2023

DT and Ericsson recently demonstrated an impressive proof of concept implementation: they established connectivity with guaranteed quality of service (QoS) between Germany and Poland via 5G end-to-end network slicing. With an SD-WAN solution from Deutsche Telekom, the data connection can be flexibly controlled and managed via a customer portal. The solution ensures that different service parameters in the network can be operated across country borders. At the same time, network resources are flexibly allocated. This approach is being presented for the first time worldwide. It is particularly advantageous for global companies that operate latency-critical applications at different, international locations.

End-to-end network slicing, which requires a 5G SA core network, is a key enabler for unlocking 5G opportunities. It’s been highly touted to drive business model innovation and new use cases across various industry segments. 5G slicing will enable use cases that require specific resources and QoS levels. Globally operating enterprise are more and more seeing the need for uniform connectivity characteristics to serve their applications in different markets. Some of the latency-critical business applications that demand consistent international connectivity performance are related to broadcasting, logistics, and automotive telematics.

In this trial, the QoS connectivity was extended from Germany to Poland using a 5G slicing setup that is based on commercial grade Ericsson 5G Standalone (SA) radio and core network infrastructure and a Deutsche Telekom commercial SD-WAN solution. The home operator-controlled User Plane Function (UPF) is placed in Poland as the visited country and the entire setup is managed by an Ericsson orchestrator integrated with a Deutsche Telekom business support system via open TM Forum APIs. Combining 5G slicing and SD-WAN technology allows flexible connectivity establishment and control, while traffic breakout close to the application server in visited countries enables low latency.

…………………………………………………………………………………………………………………………………..

According to Light Reading, Deutsche Telekom (DT) has already issued a request for quotation (RFQ) to Open RAN vendors and is currently selecting partners for a commercial rollout next year.  NEC – a Japanese vendor of radio units (among other things)- and Mavenir -a U.S. developer of baseband software-were mentioned as Open RAN Town participants (and likely DT RFQ respondents). “It is a multivendor setup,” said DT’s Claudia Nemat.

However, there are obstacles that Open RAN must overcome to be widely deployed. In particular, energy efficiency. Deutsche Telekom, along with most other big operators, is determined to reduce its carbon footprint and slash energy bills. Open RAN “is less energy efficient than today’s RAN technology,” Ms. Nemat said.  The use of x86 general-purpose microprocessors in virtualized, open RAN deployments seems to be responsible for this inefficiency.

“If you have an ASIC [application-specific integrated circuit] for baseband processing, it is always cheaper than using a general-purpose microprocessor like an Intel processor,” said Alex Choi, Deutsche Telekom’s head of strategy and technology innovation, two years ago.

One option is to use ASICs and other chips as hardware accelerators for more efficient baseband processing. Companies including Marvell, Nvidia and Qualcomm all have products in development for sale as merchant silicon in open RAN deployments. Nemat, noted a breakthroughs with Intel.

“We achieved a reduction of electricity consumption of around minus 30%.  For us, that is a big step forward for commercial deployment.”

Light Reading’s Iain Morris, provided this assessment:

Even so, a commercial open RAN deployment involving companies like NEC and Mavenir is hard to imagine. Any widespread rollout of their technologies would mean swapping out equipment recently supplied by Ericsson or Huawei (DT’s current 5G network equipment vendors), unless Deutsche Telekom plans to run two parallel networks. Either option would be costly.

Far likelier is that a 2023 deployment will be very limited. Other operators including the UK’s BT and France’s Orange have talked about using open RAN initially for small cells – designed to provide a coverage boost in specific locations.

A private network for a factory is one possible example. Outside Germany, of course, there may be a bigger short-term opportunity in Deutsche Telekom markets where 5G has not been as widely deployed.

In late June 2021, Deutsche Telekom switched on its ‘O-RAN Town’ deployment in Neubrandenburg, Germany. O-RAN Town is a multi-vendor open RAN network that will deliver open RAN based 4G and 5G services across up to 25 sites. The first sites are now deployed and integrated into the live network of Telekom Germany. This includes Europe’s first integration of massive MIMO (mMIMO) radio units using O-RAN open fronthaul interfaces to connect to the virtualized RAN software.

Ms. Nemat said at the time, “Open RAN is about increasing flexibility, choice and reinvigorating our industry to bring in innovation for the benefit our customers. Switching on our O-RAN Town including massive MIMO is a pivotal moment on our journey to drive the development of open RAN as a competitive solution for macro deployment at scale. This is just the start. We will expand O-RAN Town over time with a diverse set of supplier partners to further develop our operational experience of high-performance multi-vendor open RAN.”

……………………………………………………………………………………………………………………………………………………………………..

In November 2021, Deutsche Telekom announced it was taking the lead in a new Open lab to accelerate network disaggregation and Open RAN. The German Federal Ministry for Transport and Digital Infrastructure (BMVI) is financing the Lab with 17 million Euros and that’s to be matched by approximately a 17 million Euro investment from a consortium under the leadership of Deutsche Telekom (DT).

The lab will furthermore be supported by and working closely with OCP (Open Compute Project), ONF (Open Networking Foundation), ONAP (Open Network Automation Platform), the O-RAN Alliance and the TIP (Telecom Infra Project). Partners and supporters together form the user forum, which is open for participation by other interested companies, especially SMEs, working on applications as well as equipment and development. As an open lab it is built for collaboration within the wider telecommunications community. The i14y Lab Berlin will be the central location and core node of satellite locations such as Düsseldorf and Munich.  Other highlights:

  • Testing and integrating components of disaggregated networks in the lab to accelerate time to market of open network technology for the multi-vendor network of the future.
  • The lab has already started operations at DT Innovation Campus Winterfeldtstraße
  • Important foundation for building a European and German ecosystem of vendors and system integrators

A recent Research Nester report predicts a market size of $21 billion for O-RAN in 2028.

Deutsche Telekom expands its fiber optic network in 78 cities and communities

Deutsche Telekom said it has expanded its fiber optic network for almost 7,000 companies in 78 cities and communities. Telekom is providing the companies with up to 1 Gbps speeds. The German based telco has connected industrial parks in the municipalities of Ahrensburg, Deggendorf, Lastrup, Lauf, Mainz and Mannheim among others.

Telekom is laying 560 km of fiber-optic networks to carry out the project and to connect the companies. It is using a trenching process to expand its fiber network.

“Telekom is Germany’s digital engine. That is why we are building our network seven days a week, 24 hours a day. In the city as well as in the countryside. We are massively accelerating our roll-out. In the coming year, we will go one better and invest around six billion euros in Germany. By 2030, every household and every company in Germany should have a fiber-optic connection. We will build a large part of this. But our competitors are also in demand,” said Srini Gopalan, Member of the Board of Management of Telekom Deutschland.

He also commented on the new German government’s plans in terms of digitization: “The new coalition is focusing on FTTH as THE technology of digitization. We explicitly welcome this. Faster processes – including for applications and approvals – will also help us to speed up fiber roll-out. We support the digital set off in our country. Digital networks should bring people together. Their roll-out should no longer be stuck in paper files.”

Deutsche Telekom launches 5G private campus network with Ericsson;  Sovereign Cloud for Germany with Google in Spring 2022

Overview:

Ericsson and Deutsche Telekom have partnered to deliver a new 5G Standalone (5G SA) private campus network offering, aimed at on-site business communications infrastructure. The new campus network offering is based on a local 5G infrastructure that is exclusively available for the customer’s digital applications. The 5G SA technology works without LTE anchors (as in 5G NSA) and offers all the technical advantages of 5G – even for particularly demanding and safety-critical use cases: fast data transmission rates, maximum network capacity and highly reliable connectivity with low latency.

With the advanced 5G SA technology, Deutsche Telekom and Ericsson support companies from a wide range of industries in developing innovative digital applications and making existing processes more efficient.

The newly offered 5G SA Campus network – powered by the Ericsson Private 5G portfolio – operates completely separated from the public mobile network: all components of the infrastructure from the antennas to the standalone core network to the network server are located on the customer’s premises. This ensures that sensitive data remains exclusively within the local campus network. The local connection of the customer infrastructure also enables particularly simple and fast processing of data via the private network. This standalone 5G architecture of “short distances” is most suitable for supporting business-critical applications that require ultra-short response times in the millisecond range. The 5G SA network operates on frequencies in the 3.7 to 3.8 GHz range that are specifically allocated to the enterprise. Thus, up to 100 MHz bandwidth is available for the exclusive use within the private campus network.

The new 5G private campus network is being launched in Germany under the name “Campus-Netz Private” – and will be offered to business customers in other European countries.

……………………………………………………………………………………………………………………………………………………………………………………..

Analysis: It is quite interesting that Deutsche Telekom chose Ericsson as it’s 5G SA Core network vendor, rather than hyper-scalers like Amazon AWS or Microsoft Azure who are building 5G SA core networks for Dish Network and AT&T respectively.  Amazon also offers its own private 5G network directly to enterprise customers.  So does Microsoft which offers Azure private multi-access edge compute.  Earlier this year, Fierce Wireless reported that Google did NOT have a private 5G network offering, but was partnering with other companies to offer one.

……………………………………………………………………………………………………………………………………………………………………………………..

Sidebar:

Deutsche Telekom’s T-Systems has partnered with Google Cloud to build and deliver sovereign cloud services to German enterprises, healthcare firms and the public. The two companies say that the goal of this sovereign cloud is to allow customers to host their sensitive workloads while still being able to leverage all the benefits of the public cloud, such as scalability and reliability. The launch of the new Sovereign Cloud for Germany will take place ahead of schedule: Telekom’s business customer arm T-Systems and Google Cloud are launching their new sovereign cloud service in spring 2022. It will be available for all clients, initially out of the Frankfurt Google Cloud Region. Telekom and Google confirmed that they will jointly drive innovation for the cloud, closely aligned with the new German government’s digital plans which aims to build a public administration cloud based on a multi-cloud strategy and open interfaces, as well as meeting strict sovereignty and transparency requirements. To this end, the partners are setting up a Co-Innovation Center in Munich as announced in November 2021. In addition, executive briefing facilities in Munich and one in Berlin will be established for close collaboration with customers.

“Many companies in Germany state that sovereignty matters to them when choosing their Cloud provider. This is particularly important for key sectors such as public, healthcare and automotive,” Höttges said. “That’s why we’re delighted to offer a Sovereign Cloud that addresses additional European compliance requirements.”

In this new joint offering, T-Systems will manage a set of sovereignty controls and measures, including encryption and identity management. In addition, T-Systems will exercise a control function over relevant parts of the German Google Cloud infrastructure. Any physical or virtual access to facilities in Germany (such as routine maintenance and upgrades) will be under the supervision of T-Systems and Google Cloud.

……………………………………………………………………………………………………………………………………………………………………………………..

5G SA Campus Network: Full Control & Flexible Deployment:

Customers can adapt their private 5G SA network flexibly according to their own requirements as well as manage it independently: Whether for real-time communication of robots in factories or for connecting automated vehicles on company premises. Customers can prioritize data traffic within their campus network for specific applications as needed.

The mobile network is administered on site via a cloud-based network management portal by the customer’s IT staff – for example, the administration of users, 5G modules and SIM cards to access the 5G-SA campus network or to the machine control system. The closed system is characterized by its particularly high data security and reliability: Due to the redundant architecture of the local core network, the 5G SA campus network continues to function reliably even in the event of an interruption to the cloud-based management portal.

Managed service by Deutsche Telekom:

If business customers decide to deploy their own 5G SA network, Deutsche Telekom analyzes with them the critical business applications and the requirements for the private mobile network. Due to the simplified local infrastructure, the network can be built from planning to the handover to the customer within just three months. Network equipment supplier Ericsson provides the required modern 5G SA technology, while Telekom takes on the planning, deployment, operation as well as maintenance and optimization. Telekom also provides the set-up and updates so that companies can focus on their core business.

“When it comes to digitalization, industry and SMEs need a reliable partner,” says Hagen Rickmann, Managing Director Business Customers at Telekom Deutschland GmbH. “Together with Ericsson, we help business customers in every industry to increase their productivity and exploit their full potential using 5G standalone technology.”

Arun Bansal, Executive Vice President and Head of Market Area Europe & Latin America at Ericsson says: “Deutsche Telekom and Ericsson share a long-standing partnership in innovation, technology and services. Together, we offer secure, reliable and high-performance network solutions tailored to the specific business needs of our customers.”

5G Campus Network Private – Available for testing on site:

Deutsche Telekom has already been offering campus network solutions for enterprises since the beginning of 2019 and by now operates more than ten of such local networks based on 5G non-standalone technology or LTE across Germany. With the new fully private 5G SA Campus network solution, the company is expanding its business customer offering with the next development stage of 5G. The new product is being launched in Germany from now on under the name “Campus-Netz Private” – and is also offered to business customers in further European countries. For interested customers, mobile Campus 5G SA test systems are available to test their own use cases on site.

Use Cases and Industry Verticals:

There is currently a huge drive to get private 5G networks onto factory floors for manufacturing.  There are some interesting examples of using IoT technology, feeding information back via high speed wireless connections, and analyzing data with machine learning/AI tools to optimize operations and do new things like predictive maintenance.  Ericsson touts several industry verticals as candidates for its 5G private network offerings: Airports, Energy Utilities, Airports, Mining, Manufacturing, Ports, Offshore and Processing.

The drive towards business 5G adoptions is reflected In Ericsson’s Q4 2021 financials, in which private networks for enterprise were cited as one of the key drivers of its 41% YoY jump in profit. Evidently, Ericsson and Deutsche Telekom see a lot of potential in private 5G for industrial applications.

ONF and Deutsche Telekom Demonstrate Fully Disaggregated Open RAN and SD-WAN

Deutsche Telekom is working with the Open Networking Foundation (ONF) and eight vendors to test software-defined radio access networks (SD-RAN) and Open RAN in what it calls a fully disaggregated system.  This is the first field trial implementing fully disaggregated open RAN solutions using ONF’s RAN Intelligent Controller (RIC) software platform as defined by the O-RAN architecture. This 4G and 5G Standalone (SA) outdoor trial is live at Deutsche Telekom in Berlin, Germany.

In addition, the Facebook-backed Telecom Infra Project (TIP) is taking part by providing hardware and facilities out of the TIP Community Lab in Berlin hosted by Deutsche Telekom.

Carriers are investing in open RAN to enable a new breed of modular and customizable 5G solutions to accelerate innovation and enable the mix-and-match of best-of-breed components from multiple vendors.  Open RAN gives operators choice and flexibility to customize and optimize their networks. This SD-RAN trial hosted by DT highlights the promise and flexibility of open RAN by integrating components from eight companies: AirHop, Edgecore, Facebook, Foxconn, Intel, Radisys, Supermicro and Wiwynn. Additionally, the Telecom Infra Project (TIP) is participating by providing hardware and facilities out of the TIP Community Lab in Berlin hosted by DT. The on-site field trial integration and testing is being coordinated and supported by Highstreet Technologies.

The live trial features horizontally disaggregated hardware (separate RU, DU, and CU units), as well as vertically disaggregated software components including an open source near real-time RIC (nRT-RIC) and xApps coming from the ONF’s SD-RAN project. By integrating proprietary and open source components, including a near real-time RIC and xApps, this ground-breaking trial exemplifies a model for how future open RAN deployments are envisioned to take shape.

The entirety of the trial is operationalized leveraging ONF’s Aether platform, a centrally-managed, multi-cloud, cloud-native platform providing Connectivity-as-a-Service, and highlights network slicing with multiple UPFs running at the edge. The SD-Core component of Aether provides 5G connectivity and the control plane running from the public cloud while SD-Fabric is a fully programmable network fabric optimized for the edge cloud used to instantiate a P4-based 4G/5G UPF in hardware.

Aether hosts the Radisys containerized CU while the Intel® Smart Edge Open (formerly known as OpenNESS) software toolkit hosts the Radisys DU to enable cloud-native deployment of the RAN workload with optimization on  the 3rd Gen Intel® Xeon® Scalable processor and Intel® vRAN Dedicated Accelerator ACC100. The CU and DU are integrated with ONF’s nRT-RIC, xApps, SD-Core 5G core and Foxconn O-RU.

Deutsche Telekom and partners complete 1st Voice over 5G New Radio call

Deutsche Telekom (DT) together with partners Ericsson, Nokia, Qualcomm, Samsung, Xiaomi announced the successful completion of the world’s first Voice over 5G New Radio (VoNR) call in an end to end multi-vendor environment.

The trial was in DT’s lab in Warsaw, Poland [1.].  The partners were able to verify the capability over a 5G Standalone (SA) network with voice and 5G data sessions in parallel. This network setup integrated a 5G Core from Ericsson and IP Multimedia Subsystem (IMS) from Nokia. The calls were completed on commercial terminals from Samsung Galaxy S21 5G, Xiaomi Mi 11 Lite 5G, and a 5G smartphone form factor test device powered by Qualcomm’s Snapdragon 780G and 888 5G Mobile Platforms with Snapdragon 5G Modem-RF Systems.

The partners said that “innovation milestone is an important step towards the commercial introduction of seamless native 5G voice services in Deutsche Telekom networks.”

Note 1. Deutsche Telekom, together with Nokia and Ericsson, established the 5G Standalone network infrastructure in test mode at Deutsche Telekom’s lab in Warsaw, Poland, where testing and engineering is conducted on behalf of the entire Group.

 

Timotheus Höttges CEO Deutsche Telekom

……………………………………………………………………………………………………………………………………………

In cloud-native 5G SA networks, operators will be able to deliver high quality voice services without having to rely on LTE as anchor. The addition of VoNR to the superior data transmission quality of 5G technology will allow customers to enjoy voice and data services in parallel. VoNR is therefore expected to play a role in many data services enabled by 5G, from enhancements to voice quality in existing services to completely new services around immersive video conferencing and augmented or virtual reality.

“High quality and seamless voice calling remains a must-have service for our customers in the 5G era. The addition of 5G VoNR can be a differentiator for next generation immersive applications that integrate high speed 5G data with high definition audio,” says Alex Choi, SVP Strategy & Technology Innovation, Deutsche Telekom. “Our collaboration with best-in-class partners to validate end-to-end 5G VoNR interoperability is an important step towards the future of 5G voice services for our customers.

Jan Karlsson, Senior Vice President and Head of Digital Services, Ericsson, says, “The end-to-end 5G voice over NR going live with the first call in Deutsche Telekom network further demonstrates the strength and recognition of our cloud native 5G Core network for standalone 5G networks.”

Marc Erhardt, Head of Cloud and Network Services in the Customer Team Deutsche Telekom, Nokia says, “Voice communication remains a key feature also in the 5G world. Subscribers demand high-quality voice services and voice also plays a role in many of the new data services enabled by 5G. Successful 5G strategies therefore must include a plan for embedding voice into 5G services, and the IMS core will be key for this. Our participation in this successful trial is the latest validation reflecting the strong capabilities of the Nokia IP Multimedia Subsystem and Telephony Application Server.”

“This achievement is a step forward in realizing the full potential of 5G for consumers and industries. The capabilities of mature 5G networks will bring significant benefits to end-users as well as produce a plethora of innovative new services and applications,” says Enrico Salvatori, senior vice president and president, Qualcomm Europe/MEA, Qualcomm Europe, Inc.

“Both the Xiaomi Mi 11 Lite 5G and the 5G smartphone form factor test device used in this activity are powered by Snapdragon 780G and 888 5G Mobile Platforms with Snapdragon 5G Modem-RF Systems respectively which support a wide range of 5G capabilities including both 5G VoNR and 5G SA.”

“Galaxy 5G devices are already changing the way we communicate and how we experience the world around us,” says KJ Kim, EVP and Head of Mobile R&D Office, Mobile Communications Business, Samsung Electronics. “Samsung’s longstanding partnership with Deutsche Telekom continues to lead the growth of 5G and as Galaxy S21 5G comes with next generation 5G VoNR, we look forward to giving more people access to innovative mobile experiences.”

“Close collaboration along 5G ecosystem is crucial to unlock the true potential of 5G.” Says James Munn, Head of Global Carrier Operations, Xiaomi. “Combining new 5G services, such as VoNR, with our world-class 5G smartphones will ensure we are able to offer the best possible experience to our customers.”

To achieve this 5G VoNR breakthrough Deutsche Telekom, together with Nokia and Ericsson, has established the 5G Standalone network infrastructure in test mode at Deutsche Telekom’s lab in Warsaw, Poland, where testing and engineering is conducted on behalf of the entire Group.

The setup includes the integration of a 5G Core (5GC) from Ericsson and an IMS (IP Multimedia Subsystem) from Nokia, whereby the IMS core provides voice as a 5G application service. The transmission was tested over 5G NR Standalone (SA) Radio Access Technology from both Ericsson and Nokia. The voice calls were completed using the Samsung Galaxy S21 5G, Xiaomi Mi 11 Lite 5G, and a 5G smartphone form factor test device powered by the Snapdragon 780G and 888 5G Mobile Platforms with Snapdragon 5G Modem-RF Systems.
