Internet 2’s Next Generation Infrastructure team deploys 800Gbps optical link
On February 26, 2021, Internet2 deployed its first 800 Gbps single-carrier optical circuit between Phoenix and Tucson, AZ as part of its Next Generation Infrastructure (NGI) program.
This milestone marks the first 800G native link to be deployed by a U.S. research and education network. The optical circuit leverages a 102 Ghz carrier generated by a single Ciena Waveserver 5 transponder at each endpoint.
On February 25, 2021, the Internet2 project team completed the upgrade of all Reconfigurable Optical Add-Drop Multiplexers (ROADMs) to flex spectrum on all east-west long-haul routes nationwide. Additionally, the majority of the optical fiber was upgraded from LEAF to SMF28 to better match the coherent transmission technologies being used to convey the new 800 Gbps optical link.
Internet2 plans to rapidly expand its 400G and 800G transmission capabilities along these newly flex-grid enabled routes; more link capacity will come online as our phase 2 hardware deployment team (GDT) continues to move across the country. The Internet2 team is deploying the Cisco 8200 and Ciena Waveserver 5 platform. Completion is targeted for the end of this month (March 2021).
The successful deployment of this initial 800 Gbps optical link is the culmination of thousands of hours of effort from both the Internet2 community and teams in many organizations, including Internet2, GlobalNOC at Indiana University, Ciena, Lumen, and GDT.
Just two weeks ago, Telefonica said it had trialed an 800 Gbps optical link, using Huawei and Nokia network equipment. However, there are no 800 Gps links in any commercial production network, as far as we can determine.

What is WiFi 6 and 6E?
The IEEE 802.11ax standard was dubbed Wi-Fi 6 by the WiFi Alliance. At the time of publication, it was limited by U.S. law to a wireless spectrum that only covered the 2.4GHz and 5GHz bands.
In a 2.4GHz band, there are three non-overlapping channels—and that bandwidth is shared by all users. If too many end point WiFi devices compete for bandwidth on the same wireless channel, then some of those signals will be dropped.
In April of 2020, the Federal Communications Commission (FCC) voted unanimously to open up the 6GHz band for unlicensed use. With that policy change, significantly more airwaves are open that WiFi routers can use. The WiFi Alliance named versions of IEEE 802.11ax that operate at or above 6GHZ as WiFi 6E.

…………………………………………………………………………………….
The opening of the 6GHz band is essentially quadruples the amount of airwaves (14 additional 80MHz channels, and seven additional 160MHz channels) available for WiFi routers and smart WiFi devices. That means less signal interference.
Wi-Fi Alliance® is introducing new terminology to distinguish forthcoming Wi-Fi 6 devices that are capable of 6 GHz operation, an important portion of unlicensed spectrum that may soon be made available by regulators around the world. Wi-Fi 6E brings a common industry name for Wi-Fi® users to identify devices that will offer the features and capabilities of Wi-Fi 6 – including higher performance, lower latency, and faster data rates – extended into the 6 GHz band. Wi-Fi 6E devices are expected to become available quickly following 6 GHz regulatory approvals, utilizing this additional spectrum capacity to deliver continuous Wi-Fi innovation and valuable contributions to consumers, businesses and economies.
So, what’s the difference?
Early-adopter devices using Wi-Fi 6 (such as the first batch of Wi-Fi 6 routers) are limited to the 2.4GHz and 5GHz spectrum, while Wi-Fi 6E-compliant devices will have access to all those much richer 6GHz airwaves.

IBM’s Cloud Satellite service in Generally Available Orbit
IBM’s Cloud Satellite service is now in generally available (GA) orbit. The service extends the IBM Cloud control plane to run virtually anywhere, whether that be on commodity hardware, some edge device, or inside another public cloud.
IBM manages Cloud Satellite deployments, which is different than from most other software-defined hybrid cloud platforms. It provides an administrative control plane and as-a-service operation of IBM cloud services using a Kubernetes (K8s) cluster.
IBM explained that the GA push now makes the platform available to all customers. It allows users to run their IBM Cloud service on-premises or in edge locations managed through a single pane of glass in the public cloud.
The first two services for IBM Cloud Satellite will be Cloud Pak for Data and OpenShift as a Service.
IBM’s not alone in looking to data as one of the first services to be offered on hybrid. Amazon Outposts offers RDS for MySQL and PostgreSQL; Azure Arc data services include SQL Managed Instance and PostgreSQL Hyperscale; while Google recently added BigQuery Omni to its Anthos software-defined hybrid cloud as part of a multi-cloud and edge play.
The rationale as to why data services are so elemental to hybrid cloud is that, for many organizations or use cases, data needs to stay local for reasons ranging from latency issues to data residency requirements. OpenShift as a service will provide a route for customers seeking to build their own private cloud K8s environments. IBM is announcing that this will also be early on the list.
As part of this collaboration, customers will be able to:
- Deploy applications across more than 180,000 connected enterprise locations on the Lumen network to provide a low latency experience
- Create cloud-enabled solutions at the edge that leverage application management and orchestration via IBM Cloud Satellite
- Build open, interoperable platforms that give customers greater deployment flexibility and more seamless access to cloud native services like AI, IoT and edge computing
IBM said it has more than 65 “ecosystem partners” building services to run in the Cloud Satellite environment. Partner include Cisco, Dell Technologies, and Intel. They intend to develop cloud services which can run across the multi-cloud and premises platform services include storage, networking, and server options.
“IBM is working with clients to leverage advanced technologies like edge computing and [artificial intelligence], enabling them to digitally transform with hybrid cloud while keeping data security at the forefront,” said Howard Boville, Head of IBM Hybrid Cloud Platform, in a statement. He added that “clients can securely gain the benefits of cloud services anywhere, from the core of the data center to the farthest reaches of the network.”
IBM highlighted three partners, among them Lumen Technologies and Portworx, that are both heavily leveraging 5G to deliver PaaS services for edge computing, and F5, which is developing vertical solutions for banking institutions.
IBM noted that Lumen Technologies (formerly CenturyLink) was using the hybrid cloud platform to deliver its Edge Compute service. That capability relies on Red Hat’s OpenShift that runs within Cloud Satellite to host the applications running close to Lumen’s edge locations. Lumen touts that it has approximately 450,000 route fiber miles in its network spread across more than 60 countries.
Lumen struck a similar deal earlier this year with VMware that will see both vendors “fast-track the design, development, and delivery of edge computing and more secure, work-from-anywhere solutions.”
Does anyone remember IBM’s Satellite Business Systems (SBS) of the late 1970s? It was a pioneer in delivering data services to businesses as a precursor of the Internet.

Deutsche Telekom & Ericsson CEOs: Europe’s Dysfunctional Telecom Industry Must Consolidate
Europe’s telecommunications industry needs to consolidate, Deutsche Telekom Chief Executive Tim Hoettges said on Friday, as the region’s 100 operators invest more in 5G networks at a time when revenue and profits are under pressure.
“The industry is in a dilemma that it can only escape through cost synergies,” Hoettges told a news conference, repeating earlier calls for consolidation. “I believe deeply that European consolidation is necessary.” Yet the Germany-based telecom provider, that owns a majority stake in T-Mobile US, is not in active merger talks.
Earlier this month, Borje Ekholm, chief executive of Sweden based equipment maker Ericsson told the Financial Times that Europe has a “non-functioning” telecoms market. Ekholm suggested it was rational for Europe’s telecoms operators not to invest in 5G networks, because many of them failed to earn their cost of capital. “The problem is that the guys that are supposed to build out that infrastructure (wireless telcos) don’t make any money. There is a very big cost to waiting,” he added.
Ericsson is worried that Europe is falling far behind China and the U.S. in the rollout of 5G, which it argues will be crucial for the digitalization of businesses. The company has forecast that 5G could boost the continent’s gross domestic product by 2 percentage points a year.
“Without [5G], general industry will be less efficient and less competitive. Without the infrastructure, it’s hard to develop the digital industry, and that impacts huge value potential and potentially millions of future jobs,” said Ekholm.
The European 5G network equipment makers — Ericsson and Finland’s Nokia — also have a big strategic and security role, as Europe grapples with how much market access to give to their Chinese rival Huawei.
Europe has dozens of telecom operators, but attempts to consolidate in some countries have been blocked by the European Commission because of competition worries. That led some operators to complain their profitability lags far behind bigger U.S. rivals.
Several countries, including Germany and the UK, are pushing for the creation of additional telecom equipment makers, as well as the opening up of networks to other companies. Ekholm expressed surprise that Europe would do anything to undermine Ericsson and Nokia, as telecoms was one of the few technology sectors where the continent had “strategic autonomy,” he said.
“It is interesting to see that now there is a discussion about giving EU subsidies to develop competing companies, mostly they are based in the US and Asia.”
He added that it was vital for Ericsson “to be in markets at the forefront of tech development: China and the U.S.”
“For us to have a presence in both China and the U.S. allows us to be a global tech leader. It is high risk to be only in one ecosystem and not the other. It could ultimately lead to the Chinese ecosystem developing faster thanks to its scale.”
Ericsson’s CEO previously spoke out about Sweden’s ban of Chinese telecoms vendors, e.g. Huawei and ZTE. Ekholm insists that there are currently too many disincentives to invest in European telecom infrastructure. He’s probably right.

Analysis: AT&T spins off Pay TV business; C-Band $23.4B spend weakens balance sheet
AT&T has agreed to create a new company for its U.S. video business unit together with private equity firm TPG Capital. The company will be called New DirecTV and include: today’s Direct TV, U-verse TV and AT&T TV (AT&T’s OTT video service) which AT&T said was “the future of TV” only 11 months ago. That was, indeed, a very short lived future!
The new company will have an estimated enterprise value of $16.25 billion. It will be headed by DirecTV CEO Bill Morrow and have its headquarters in El Segundo (California) and Denver (Colorado).
AT&T will own 70 percent of the new company, while TPG will hold 30 percent and will pay AT&T $1.8 billion in cash.
AT&T CEO John Stankey said the agreement is in line with the operator’s strategy to focus on core assets such as 5G, fiber optic network build-outs and HBO Max. The New DirecTV will provide “dedicated management focus” for the pay-TV operations while reducing AT&T’s huge debt burden.
AT&T bought DirecTV in 2015 for $48.5 billion but the actual value was closer to $66 billion including debt. AT&T recently struck $15.5 billion off the value of the DirecTV, reflecting the service’s dimmer prospects. AT&T said it would get about $7.8 billion in cash from the transaction to help pay down debts. Those proceeds include $5.8 billion that the new company will borrow from banks and pay back to AT&T.
“The disruption in pay TV did exceed our original expectations,” AT&T finance chief John Stephens said in an interview, adding that the satellite-TV business had helped generate cash for the company even as its customer base declined. Mr. Stephens said the new ownership structure is “a very attractive transaction, getting TPG’s expertise and that upfront cash payment.”
The new company will not include the WarnerMedia HBO Max streaming platform, AT&T’s Latin American video operations Vrio, AT&T’s regional sports networks, U-verse network assets and AT&T’s Sky Mexico investment.
At completion, all existing AT&T video subscribers will become New DirecTV customers and all existing content deals, including NFL Sunday Ticket on DirecTV, will become of the new company. New DirecTV will have a commercial agreement with AT&T and continue to provide bundled pay-TV services for mobile and internet customers.
New DirecTV video subscribers will also continue to receive HBO Max (which currently costs $15 per month) plus any associated discounts. AT&T and New DirecTV will also continue to serve customers through multiple distribution channels, including retail, online, call centers and indirect sellers; and share revenues for ad inventory management and ad sales.
The new company’s board will have two representatives from both AT&T and TPG, with Morrow holding the fifth seat. Most AT&T video services employees will move to New DirecTV. The new company plans to recognize its unionized labor force and will assume and honor all existing collective bargaining agreements.
The deal is expected to close in second half of this year. Under the terms of the agreement, AT&T will receive $7.8 billion from New DirecTV, including $7.6 billion in cash and the assumption from AT&T of $200 million worth of existing DirecTV debt. AT&T will use the proceeds to reduce its debt. TPG will contribute $1.8 billion in cash to New DirecTV in exchange for preferred units and its 30 percent stake in the new company.
“This agreement aligns with our investment and operational focus on connectivity and content, and the strategic businesses that are key to growing our customer relationships across 5G wireless, fiber and HBO Max. And it supports our deliberate capital allocation commitment to invest in growth areas, sustain the dividend at current levels, focus on debt reduction and restructure or monetize non-core assets,” said AT&T CEO John Stankey.
“As the pay-TV industry continues to evolve, forming a new entity with TPG to operate the U.S. video business separately provides the flexibility and dedicated management focus needed to continue meeting the needs of a high-quality customer base and managing the business for profitability. TPG is the right partner for this transaction and creating a new entity is the right way to structure and manage the video business for optimum value creation.”
“We look forward to working with AT&T, Bill and the entire talented team at the new DIRECTV to create a seamless customer experience through the separation of the company,” John Flynn, Principal at TPG said. “We are particularly excited by the opportunity to grow new DIRECTV’s streaming video service, leveraging the company’s leading pay-TV platform, talented labor force and large subscriber base to transition it into a leading next-generation video provider with best-in-class content and customer experience.”
AT&T lost 7 million domestic pay-TV subscribers over the last two years. Comcast lost about 2 million such customers over the same period. Dish Network Corp. , DirecTV’s satellite-TV rival, shed roughly 1 million subscribers.
Financing the Deal:
New DirecTV has secured $6.2 billion in committed financing from its bank group, $5.8 billion of which will be used to pay AT&T and assume the $200 million of agreed debt.
AT&T also agreed to cover up to $2.5 billion in losses tied to DirecTV’s NFL Sunday Ticket package.
AT&T financial impact:
AT&T’s net debt load, which was listed above $180 billion after the Time Warner transaction, recently stood around $148 billion.
In 2021, AT&T expects to apply the cash proceeds from the transaction toward debt reduction and does not expect a material impact to its 2021 financial guidance for:
• Consolidated revenue growth in the 1% range
• Adjusted EPS to be stable with 2020
• Gross capital investment in the $21 billion range with capital expenditures in the $18 billion range
Following close of the transaction, AT&T expects to deconsolidate the U.S. video operations from its consolidated results. The company will continue to look at ways of “monetizing non-core assets.”
Opinion – AT&T’s C-Band Spend Adds to Debt and Weakens its Balance Sheet:
The company added that it has proactively managed its debt portfolio, reducing near-term debt maturities by about $33 billion in 2020 and lowering the overall portfolio average rate to 4.1 percent at the end of 2020, down 20 basis points from first-quarter 2020 levels.
However, AT&T has not said how it would pay for the $23.4B they spent to acquire spectrum at the recently completed C-Band auction, other than the $14.7B it raised raised in a loan-credit agreement with Bank of America earlier this year.
Moody’s Investors Service on Wednesday told clients that AT&T’s C-Band spectrum splurge could pressure AT&T’s credit rating, which sits two notches above junk territory. In a brief note Thursday, Moody’s called the DirecTV deal “moderately credit positive” because it would produce cash to help cover the spectrum costs.
Oppenheimer analysts believe that spectrum build-out in new 5G deployments will take at least a year and the resulting revenue won’t show up for a few years. We believe that AT&T will be very hard pressed to fund the spectrum buildout within the next two or three years due to delays in installing hundreds of thousands of small cells and fiber to them for backhaul.
Analyst Craig Moffett had this to say: “At $23.4B, AT&T spent more than would have been expected a month ago, but expectations for their spend had been rising (notwithstanding the fact that they have onlyfinanced half of what they bought, and even that with only short-term debt), so the surprise may not be large there, either. But again, it’s a shock to see the number.”
“AT&T emerges from the auction with leverage of 4.1x EBITDA (assuming all debt financing)……AT&T, in particular, will face enormous pressure to withdraw its hyper-aggressive promotional stance in order to produce enough free cash flow to sustain their dividend – but that is cold comfort for an industry whose ROI will inarguably be even worse than it has been in the past.”
Craig noted that C-Band spectrum will require many more small cells which require permits, time and effort to install. That will delay AT&T’s 5G network expansion using the newly acquired spectrum:
“3.5 GHz spectrum (again, as a rough proxy for C-Band) requires sixteen times as many cell sites as would 2.0 GHz spectrum for the same free space coverage. And because C-Band will have very limited ability to penetrate obstructions (trees, walls and windows, intervening buildings, etc.), real world propagation limitations will likely be even greater than what a free space model would suggest.”

Equinix and Vodafone to Build Digital Subsea Cable Hub in Genoa, Italy
Equinix and Vodafone have announced plans to build a new subsea cable hub in the northern Italian port of Genoa, to be called GN1.
Under the deal, Vodafone will land the 2Africa cable system at Genoa and use Equinix’s GN1 facility as a strategic interconnection point for the subsea cable system, with a connection on to Milan and the rest of Europe.
The partners said the EUR 1 billion 2Africa cable will be ready for service in 2023, a 37,000 km system circumnavigating the continent of Africa and directly connecting 16 countries in Africa to Europe and the Middle East, with a design capacity of up to 180 Tbps on key segments. To facilitate interconnection, GN1 will have a direct fiber connection to ML5, the soon-to-be opened Equinix flagship data center in Milan.
The newly-announced GN1 hub will be Genoa’s first carrier-neutral data center, offering customers secure colocation and interconnection services, as well as the ability to directly tap into Equinix’s digital ecosystems and colocation facilities in Milan. It will provide a capacity of 150 cabinet equivalents, and colocation space of around 560 square meters.
The combination of 2Africa’s landing in the new Genoa site and the direct connection to Milan means GN1 will offer a new, complementary and diverse alternative option for the Mediterranean region. As Genoa’s first carrier-neutral data center, GN1 will offer customers secure, resilient colocation and interconnection services, as well as the ability to directly leverage Equinix’s digital ecosystems and colocation facilities in Milan. It will provide a capacity of 150 cabinet equivalents, and colocation space of approximately 6,000 square feet (560 square meters).
2Africa is expected to deliver more than the total combined capacity of all subsea cables serving Africa today, with a design capacity of up to 180 Tbps on key segments of the system. This will be vital to help build a digital society ready for services that require a large amount of data transfer, such as cloud computing or video.
The need for robust digital infrastructures can be seen across the world, and Africa is no exception. The continent is experiencing a critical period of digital transformation and development of its digital economy. In the next few years, digital technologies are expected to be a factor in improving African people’s quality of life and driving economic development in the region.
The GSMA predicts that the number of mobile internet users in Africa will continue to grow rapidly, primarily due to the popularization of smartphones and lack of fixed-line infrastructure, which has led to a boom of new services such as mobile payment, instant messaging, online streaming media and short video.
Highlights/Key Facts:
- The 2Africa project includes partners from China Mobile International, Facebook, MTN GlobalConnect, Orange, stc, Telecom Egypt, Vodafone and WIOCC. The cable system will underpin digitization across the African continent by bringing greater capacity, quality and availability of internet connectivity between Africa and the rest of the world.
- Responsibility for landing the 2Africa cable is split between the 2Africa parties depending on location. Vodafone is leading all European landings, along with selected other sites.
- As the home of the interconnected cloud®, Equinix is a natural destination for subsea cable systems and a gateway to new opportunities for system operators and their customers. Equinix hosts over 2,950 cloud and IT service providers on its global platform and can support subsea cable systems in 40 subsea-enabled metros around the world. When subsea cable systems are linked to cloud and content ecosystems on Platform Equinix®, users can access a variety of scalable cloud services almost anywhere they need to be. And because Equinix is carrier-neutral, subsea system operators can offer excess network capacity to customers who otherwise couldn’t as quickly or efficiently reach the markets being served by new subsea architectures.
- GN1 is being built in line with global environmental standards and will contribute to a portfolio of some of the most energy-efficient data centers in the world. Indeed, GN1 is expected to utilize 100% renewable energy. As the world’s digital infrastructure company, Equinix is working to protect, connect and power a more sustainable digital world by proactively addressing its ESG impacts. Equinix recently scored the highest rating on its first response to the DPP’s Committed to Sustainability survey, and joined European cloud infrastructure and data center providers and European trade associations to form the Climate Neutral Data Centre Operator Pact and Self-Regulatory Initiative.
- ML5 will be a new flagship International Business Exchange™ (IBX®) data center in Milan that offers state-of-the-art colocation, as well as a host of advanced interconnection services—including Equinix Fabric™ and Equinix Internet Exchange®—enabling virtual interconnections to some of the largest cloud providers in the world, such as Amazon Web Services, Microsoft Azure, Oracle Cloud Infrastructure and Google Cloud. When opened, ML5 will provide capacity of 500 cabinet equivalents and colocation space of approximately 15,000 square feet (1,400 square meters).
- The Global Interconnection Index (GXI) Volume 4, a market study recently published by Equinix, forecasts that overall interconnection bandwidth—the measure of private connectivity for the transfer of data between organizations—will achieve a 45% compound annual growth rate (CAGR) from 2019 to 2023, globally. The expected growth is driven by digital transformation, and specifically by greater demands from enterprises extending their digital infrastructure from centralized locations to distributed edge locations.

Vodafone-Espana trial: 5G connected drone (UAS) enables Guardia Civil to improve surveillance in rural areas
Vodafone Spain has completed a trial with the Guardia Civil military police force to evaluate the viability of using 5G networks to improve surveillance using remote-controlled drones.
The pilot test consisted of using the 5G network to improve communication of the UAS (unmanned aerial vehicle systems) drone for surveillance tasks in rural areas or areas with difficult access. The drone was remotely-controlled by the Guardia Civil.
The Tarsis fixed-wing unmanned aerial vehicle system of local provider Aertec Solutions coupled with a 5G smartphone for both high-definition and 4k camera communications, as well as flight command management.
Vodafone said its 5G network provided the maximum bandwidth and minimum latency required for the transmission of high-quality images and control signals in real time, allowing specialist pilots to operate the drone remotely from a control center.
In order to carry out teleoperation safely, it was necessary to broadcast high quality images from cameras installed in the UAS and to send remote control actions or reference coordinates by the pilot.
The pilot trial was the latest test in the Andalucia 5G initiative which has been promoted by Spain’s ICT development agency Red.es, which is being developed by Vodafone and Huawei.
This is one of the two projects that Spain’s Government has promoted through the first public call for aid to 5G pilots, resolved in the spring of 2019.
Presented in November 2019 in Seville, it includes 35 use cases that will apply the benefits of 5G technology in the sectors of energy, industry, smart cities, tourism, agriculture, health and dependency, security, emergencies and defense, society and digital economy.
Vodafone said the project’s budget is EUR 25.4 million, including EUR 6.3 million from Red.es. It will cover the provinces of Seville, Jaen, Malaga, Cadiz and Huelva.

- Launching new lab environments to help communications service providers innovate for cloud native-based 5G networks.
- Making it easier for communications service providers to deliver business applications to the network edge.
“The next wave of network transformation is fueled by 5G and is driving a rapid transition to cloud native technologies,” said Dan Rodriguez, Intel corporate vice president and general manager of the Network Platforms Group, in a press release. “As communications service providers build out their cloud infrastructure, our efforts with Google Cloud and the broader ecosystem will help them deliver agile, scalable solutions for emerging 5G and edge use cases.”
The partnership’s cloud native 5G objectives will be “across the telecommunications stack, with application providers, carriers and communications service providers, hardware providers, and global telecoms,” according to the press release, to decrease the cost and time-to-market needed for the telecommunications industry.
……………………………………………………………………………………………..
Last March, Google Cloud announced a telecommunications industry strategy that focused on cloud capabilities with 5G connectivity and this builds upon that plan.
Google Cloud recently announced an initiative to deliver 200+ partner applications to the edge via Google Cloud’s network and 5G.
Opinion:
Partnerships like this one will be increasingly necessary to build 5G cloud native core networks and services (like network slicing), because there are no implementation specific standards (more below).
Ericsson wrote in a blog post:
“Of course, the implementation of a fully cloud native network will take considerable time and the new and legacy infrastructure will have to co-exist in a hybrid mode to begin with. Nevertheless, depending on your market requirements, it is important to start the journey towards a cloud native 5G Core now and focus future investments in accordance with the new target architecture. This is also the reason why we have re-designed our EPC software to also be cloud native and created a solution we call the Ericsson dual-mode 5G Core.”
“The new 5GC will live together with EPC for a considerable time and it’s important to define an evolution path that is smooth and cost efficient, while still supporting your business strategy and ambitions. We have developed a solution we call dual-mode 5G Core, where 5GC and EPC live together under one common O&M system for efficient TCO. This enables a smooth migration at your own pace and in accordance with your business needs.”

3GPP High Level Specs on 5G Network Architecture/5G Core:
The high level 3GPP technical specs for 5G Core (5GC) call for a service based architecture (SBA), which is designed for cloud native deployment.
These three 3GPP Technical Specs (TS’s) are the basis for 5G core networks, but they do not specify implementation details:
- 23.501 System architecture for the 5G System (5GS)
- 23.502 Procedures for the 5G System (5GS)
- 23.503 Policy and charging control framework for the 5G System (5GS); Stage 2
The ETSI standard is a transliteration of 3GPP TS 23.501: https://www.etsi.org/deliver/etsi_ts/123500_123599/123501/15.03.00_60/ts_123501v150300p.pdf
From section 4.2.1:
“The 5G architecture is defined as service-based and the interaction between network functions is represented in two ways.
– A service-based representation, where network functions (e.g. AMF) within the Control Plane enables other authorized network functions to access their services. This representation also includes point-to-point reference points where necessary.
– A reference point representation, shows the interaction exist between the NF services in the network functions described by point-to-point reference point (e.g. N11) between any two network functions (e.g. AMF and SMF).
Service-based interfaces are listed in clause 4.2.6.
Reference points are listed in clause 4.2.7.
Network functions within the 5GC Control Plane shall only use service-based interfaces for their interactions.”

Apple is new smartphone king, but market declined 5% in 4Q 2020
Apple doesn’t report unit sales for its devices. However, the company said revenue from iPhones grew by 17% in the fourth quarter of calendar 2020 on a year-over-year basis to $65.6 billion. Apple’s business is seasonal, and the quarter ending in December is usually the company’s biggest in terms of sales.
“The sales of more 5G smartphones and lower-to-mid-tier smartphones minimized the market decline in the fourth quarter of 2020,” said Anshul Gupta, senior research director at Gartner. “Even as consumers remained cautious in their spending and held off on some discretionary purchases, 5G smartphones and pro-camera features encouraged some end users to purchase new smartphones or upgrade their current smartphones in the quarter.”

Full Year 2020 Results:
Samsung experienced a year-on-year decline of 14.6% in 2020, but this did not prevent it from retaining its No. 1 global smartphone vendor position in full year results. It faced tough competition from regional smartphone vendors such as Xiaomi, OPPO and Vivo as these brands grew more aggressive in global markets. In 2020, Apple and Xiaomi were the only two smartphone vendors of the top five ranking to experience growth.
Huawei recorded the highest decline among the top five smartphone vendors which made it lose the No. 2 position to Apple in 2020 (see Table 2). The impact of the ban on use of Google applications on Huawei’s smartphones was detrimental to Huawei’s performance in the year and negatively affected sales.

“In 2021, the availability of lower end 5G smartphones and innovative features will be deciding factors for end users to upgrade their existing smartphones,” said Mr. Gupta. “The rising demand for affordable 5G smartphones outside China will boost smartphone sales in 2021.”
Deutsche Telekom tests 5G SA network via “Telekom cloud infrastructure”
Deutsche Telekom has started testing the “standalone” (SA) version of 5G, setting up its first 5G SA antenna site in the town of Garching, near Munich. The site will be the first in Germany with 5G core network technology, which has yet to be standardized.
The antenna site will soon be connected to a 5G Standalone core network. The core network will be implemented via a Telekom cloud infrastructure. The hallmark of 5G Standalone is that the infrastructure in the core network will also be fully upgraded to a new, cloud-based 5G architecture. This is the next evolution of 5G and also a prerequisite for new deployment options.
Deutsche Telekom has already achieved 68% coverage of the German population with non-standalone (NSA) version of 5G, which uses the existing 4G-LTE network as an anchor for all non radio aspects.
“It is important for us to be at the forefront of the further innovation steps of 5G,” says Claudia Nemat, Board Member for Technology and Innovation at Telekom. “To ensure that our customers can take advantage of technologies such as network slicing or edge computing in the future, we continue to actively drive the development of 5G and its features.”
With 5G Standalone, the network structure and architecture is changing. The 5G technology currently deployed in Germany is based on the 5G Non-Standalone (5G NSA) network architecture. This means that today’s 5G offerings are still technically dependent on a simultaneously available 4G network (LTE) and virtually “piggyback” on this network, i.e., they do not yet function completely independently.
“5G standalone is one of the goals for us with 5G,” said Walter Goldenits, head of technology at Telekom Deutschland. “The network innovation in Garching is initially the first step for us into the 5G SA live network. It helps us to gain necessary and important experience with 5G SA. A rollout in the area will then also depend on the requirements of our customers. Technology and the market will play a joint role in further development.”
There are currently no terminals for customers that support 5G standalone. Telekom is therefore conducting the first tests with special development software on commercially available devices. The goal is to test various connections and applications that function completely standalone and without the support of 4G in the coming weeks.
“The further roll-out of 5G is the preparation of our network for the next steps in 5G development. We will use every opportunity to make 5G even faster and develop it further,” says Walter Goldenits.

Last month, Samsung and Deutsche Telekom conducted their first 5G SA trial in Pilsen, the Czech Republic, verifying performance of 5G SA multi-user, multiple-input, multiple-output (MU-MIMO) technologies.
The trial used Samsung’s latest end-to-end 5G SA solutions. In the SA trial, the two companies achieved outstanding results with the MU-MIMO technology using Samsung’s 3.5GHz Massive MIMO radio. The spectrum efficiency was tripled in comparison to that of LTE under realistic conditions and the throughput was increased by about 2.5 times of SU-MIMO (Single-User MIMO).
“We are pleased to collaborate with Samsung to verify the performance of its 5G SA solution,” said Alex Choi, SVP Strategy & Technology Innovation, Deutsche Telekom. “Together with strong partners we are consistently introducing advanced technical capabilities into our network, and we are very excited about the potential of 5G SA networks to further accelerate the 5G evolution.”
Samsung also said: “5G SA architecture enables mobile operators to have more efficient and simple network operations, while empowering 5G networks to deliver immersive user experiences and new business models for enterprises.”
