Another 5G Open Innovation Lab: AT&T, Comcast, Nokia, Intel, Microsoft, Dell assist 118 startups in search of 5G Killer Apps
AT&T and Comcast have become “founding partners” of the 5G Open Innovation Lab, which invests in 5G use case development. The companies essentially replaced T-Mobile, which is no longer participating in the lab it helped to launch in 2020. The Lab now also includes Dell, Nokia, Intel, Microsoft, and Deloitte. It is currently assisting 118 startups in search of “5G Killer Apps.”
“As evidenced by the 118 startups in our ecosystem, the combination of 5G and edge is unlocking a massive wave of collaborative innovation in Cloud, Edge and AI across every industry from agriculture and power generation to manufacturing, logistics and medicine,” said Jim Brisimitzis, Founder and General Partner of the 5G Open Innovation Lab in in a statement. “We are thrilled to welcome AT&T and Comcast as founding partners to help drive our vision to bring industry experts together and, collectively, drive innovation into overlapping ecosystems. 5G and edge are new foundations that can be used to drive new business models and technology across segments and companies,” he added.
Those startups could stand to benefit from the two companies. AT&T was one of the first carriers to launch a 5G network (based on 3GPP Release 15 in December 2018) and has been working on this technology for a long time.
“Collaboration is the key to innovation,” Jay Cary, VP, Strategic Alliances, Corporate Strategy at AT&T said in a statement. “As we continue forging ahead to realize 5G’s full potential, it is important to work with the nimble startup and innovation community so we can move faster and solve real-world technology challenges more holistically and effectively for our customers.”
While Comcast doesn’t have a 5G network, the company has increasingly gotten into the wireless business through a reseller agreement with Verizon. It’s also talked about small network build outs that would increase the coverage for customers in its territories.
“The cycle of innovation often begins in small companies where a new idea can challenge existing ones, and Comcast has had success taking risks and embracing these new ideas,” Tom Nagel, senior vice president of wireless strategy at Comcast, said. “Engaging with the startup community through our own Lift Labs or with organizations like the 5G Open Innovation Lab is an important factor not only in our own efforts but to push the industry forward in exciting new ways.”
On Monday, AT&T said it’s adding thousands of new customers every day to its standalone 5G network along with subscribers to Internet Air. So far, the home broadband system has launched in 16 markets and boasts 40-140 Mbps down and 5-25 Mbps up, costs about $55 a month with no data caps. Internet Air will provide DSL customers with faster internet without having to replace copper lines, which more companies are starting to shut down.
Yesterday, Comcast said in a Securities Exchange Commission filing agreed to sell some, if not all, of its 600MHz spectrum holdings to T-Mobile. The deal is valued between $1.2 and $3.3 billion, depending on how much spectrum T-Mobile acquires. Comcast has also flirted with the idea of building its own mobile network for markets inside its cable footprint.

T-Mobile and Charter propose 5G spectrum sharing in 42GHz band
This June, we noted that the FCC was exploring shared use of the 42 GHz band using in 500 megahertz of spectrum. Recently, T-Mobile and Charter voiced support for some kind of spectrum sharing scenario.
“While wireless carriers continue to require additional spectrum that is licensed on an exclusive-use basis, T-Mobile agrees that the technical characteristics of the 42GHz band, along with its separation from other millimeter wave spectrum that has already been licensed, means that the commission may wish to consider a different approach here,” T-Mobile wrote in an August 30th FCC filing.
“The commission, however, should avoid applying untested, novel sharing approaches to the 42GHz band. Instead, it should implement the nationwide non-exclusive licensing framework currently used in the 70/80/90GHz bands, with a few modifications to ensure that the spectrum will be used efficiently and may be deployed for [a] variety of advanced communications services.”
……………………………………………………………………………………………………………………….
Charter has long eyed the 37GHz band as a way to bolster mobile operations in its planned 3.5GHz CBRS network. The MSO/cableco has said it could offer speeds up to 1 Gbit/s via concurrent operations in the CBRS and 37GHz bands.
Charter’s FCC filing is similar to T-Mobile’s, as it supports a “unified nationwide, non-exclusive simple shared licensing regime.” The company urged the FCC to implement the same spectrum sharing design across both the lower 37GHz band and the 42GHz band.
“Allocating the lower 37GHz band for non-exclusive use would offer 600 megahertz for innovative new wireless connectivity in the United States,” Charter noted. “The allocation of the 42GHz band alongside the lower 37GHz band would of course increase the total spectrum available for innovative new deployments by 500 megahertz.”
……………………………………………………………………………………………………………….
Backgrounder:
The 42GHz band resides in what is known as millimeter wave (mmWave) spectrum. 5G transmissions in those bands are at very high speeds, but they typically travel just a few thousand feet, and generally cannot pass through obstructions like walls, trees, glass or concrete, i.e. they require line of sight communications.
WRC 19 identified mmWave frequencies for 5G, but ITU-R WP 5D did not complete and agree on the frequency arrangements for same (revision 6 of ITU-R M.1036) until very recently. WRC 19 identified the frequency bands: 24.25-27.5 GHz, 37-43.5 GHz, 45.5-47 GHz, 47.2-48.2 and 66-71 GHz for the deployment of 5G networks and the frequency arrangements for them is in draft recommendation ITU-R M.1036 which is expected to be approved this November. Note that 42GHz is not included!
Some analysts are quite positive on mmWave communications. For example, “mmWave 5G offers a way to improve on the current situation because the bands have extremely high capacity that are able to support very large amounts of data traffic and users, although in a small area,” wrote OpenSignal analyst Ian Fogg in a post on the network-monitoring firm’s website.
Qualcomm is also an advocate of spectrum sharing in mmWave bands since at least July 2022.

Qualcomm’s filings to open the Lower 37 GHz band to shared licensed access ask the FCC to adopt a Notice of Proposed Rulemaking (NPRM) to allocate six 100-MHz-wide priority licenses in the Lower 37 GHz band and allow each priority operator—which may be a federal government or a commercial operator—to use the rest of the band on a secondary basis. To enable these secondary operations on an interference-free basis, each priority operator would implement a technology-neutral, equipment-based rule to provide coordinated, periodic listening of the channel, referred to as long term sensing (LTS), to determine whether its secondary operations on spectrum outside its priority licensed spectrum may cause harmful interference to the priority license holder of that swath of spectrum.
Secondary operations are only allowed for communications links that sensing determines will not cause interference to the priority licensee. The coordinated sensing procedure allows each priority license holder to access all other channels (i.e., the other 500 MHz) on a secondary – and interference-free – basis, increasing overall spectrum utilization while not degrading the QoS for the priority licensee.

Ericsson and U.S. PAWR 5G SA network for rural agricultural research
Ericsson in cooperation with the U.S. National Science Foundation’s (NSF) Platforms for Advanced Wireless Research (PAWR) program announced the launch of its 5G SA network for public research together with the Agriculture and Rural Communities (ARA) team at Iowa State University (ISU). Powered by Ericsson, the network is part of ARA’s multi-modal platform for wireless research, based on the ISU campus with coverage extending to local crop and livestock farms and parts of the city of Ames.
The Ericsson-powered 5G SA network will be used to support precision agriculture applications, along with other research initiatives, and is already connecting farm sites that previously had little to no broadband access. ARA is partnering with the ISU Department of Agriculture and Biosystems Engineering as well as the College of Agriculture of Life Sciences for initial precision agriculture research projects.

“As we continue to unlock 5G’s full potential, we’re excited to support ARA’s cutting-edge research on precision agriculture, rural broadband, renewable energy, and public safety for smart and connected rural communities,” said Per Wahlen, Vice President and Head of Business Development, Ericsson North America.
Sample agriculture research will include using connected robots (PhenoBots) to collect plant phenotyping data with stereoscopic cameras generating 800 megabits per second worth of sensor data per camera. It will also include livestock monitoring with high-resolution cameras, as well as agriculture automation.
The Ericsson-powered network consists of a 5G core operating in SA mode and NR radios which operate in both mid-band and millimeter wave spectrum bands with a high aggregate throughput up to 3Gbps. The outdoor network will run 5G SA with mid and high band New Radio-Dual Connectivity (NR-DC) with a downlink exceeding 2.5Gbps in outdoor live testing. With ultra-low latency, increased capacity and coverage, and support for end-to-end network slicing, Ericsson’s 5G SA solutions ensure instant response times and enable new use cases.
ARA is part of the National Science Foundation-funded Platforms for Advanced Wireless Research (PAWR) program that works to create wireless testbeds through public-private partnerships to accelerate the nation’s wireless ecosystem.
“As ARA aims to help close the gap between academic and industry research in the wireless and agricultural sectors, we’re excited to announce the Ericsson network component, which is open for joint opportunities for both academic and industry research endeavors,” said Hongwei Zhang, Principal Investigator of ARA and Director of the Center for Wireless, Communities and Innovation, Iowa State University.
Andrew Wooden of telecoms.com wrote:
The concept of the smart farm – like the smart city – made up part of the hype fodder for the initial 5G launch. Since 5G SA is considered ‘proper’ 5G the line seems to now be that it will be the required driving force behind all sorts of industries being revolutionised by high bandwidth and low latency mobile connectivity.
How large a commercial market applications like this represents for kit vendors like Ericsson in the near future remains to be seen, but if it does represent a teaser of how food can be grown better or more abundantly – as is presumably the end goal – we can think of much more frivolous use cases presented over the years.
These 5G SA networks my play an important role in the future of the U.S. agricultural ecosystem. ARA and Ericsson are in forward-leaning positions to support the realization of recently proposed bipartisan legislation surrounding the issue of broadband access to unserved rural farms, through applied research and innovative use case development to assist farmers and rural communities.
Electromagnetic Signal and Information Theory (ESIT): From Fundamentals to Standardization-Part II.
Part I of this two part article may be accessed here:
From ESIT Theory to Standardization:
In addition to fundamental research, several technologies originating from ESIT are currently being considering by standardization bodies (aka SDOs). This is especially true for Reconfigurable Intelligent Surfaces (RIS).
RIS relates to a new type of system node that is made with surfaces which may have reflection, refraction, and absorption properties through many small antennas or metamaterials elements which can be adapted to a specific radio channel environment.
The European Telecommunications Standards Institute (ETSI) Industry Specification Group (ISG) on RIS was officially launched on September 30, 2021 for a two-year duration. It was recently renewed for two more years.
ETSI ISG RIS set out to explore RIS and its applications across the wide spectrum of use cases and deployments to identify any specification needs that may be required, thus paving the way for future standardization of the technology.
This ISG identifies and describes RIS related use cases and deployment scenarios, specifies requirements and identifies technology challenges in several areas including fixed and mobile wireless access, fronthaul and backhaul, sensing and positioning, energy and EMF exposure limits, security and privacy.
After two years of work, ETSI ISG RIS has completed and published reports from three work items (WIs), following a consensus-based and contribution-driven working format. The contributions and discussions from ISG members and participants in this first phase of the ISG have been focused on studies related to RIS fundamental, potential, and maturity. The ETSI ISG RIS supports and encourages other standards developing organizations (SDOs) to use the group reports as baseline text for further study or their own specifications
Here’s the list of group reports approved and published by the ETSI ISG RIS as of September 2023:
GR RIS 001: Use Cases, Deployment Scenarios and Requirements
The scope of the report is on the identification and definition of relevant use cases with corresponding general key-performance-indicators (KPIs), deployment scenarios wherein RIS technology will play a role and potential requirements for each identified use case with the aim of promoting interoperability with existing and upcoming wireless technologies and networks. Aspects around system/link performance, spectrum, coexistence, and security are analyzed as part of the report.
GR RIS 002: Technological Challenges, Architecture and Impact on Standardization
The scope of the report is on the technological challenges to deploy RIS as a new network entity, the potential impacts on internal architecture, framework and the required interfaces of RIS, the potential impacts on architecture, framework and the required interfaces of RIS-integrated network, and the potential recommendations and specification impacts to standardization to support RIS as a network entity.
GR RIS 003: Communication Models, Channel Models, Channel Estimation and Evaluation Methodology
The scope of the report is on communication models that strike a suitable trade-off between electromagnetic accuracy and simplicity for performance evaluation and optimization; channel models that include path-loss and multipath propagation effects, as well as the impact of interference for application to different frequency bands; channel estimation, including reference scenarios, estimation methods, and system designs; and key performance indicators and evaluation methodology of RIS for application to wireless communications, including the coexistence between different network operators, and for fairly comparing different transmission techniques, communication protocols, and network deployments.
Further information on the ISG RIS terms of reference, work program, planned group reports, and other documentation are available through the ISG portal.
Editor’s Note: A study item related to RIS has been proposed by the industry in Release 18 (2022) and will be discussed for future plans in Release 19. The results have not yet been released.
Conclusions:
In conclusion, although ESIT may appear a pure theoretical subject, it is an essential tool for modeling, understanding, analyzing, and optimizing emerging communications technologies.
While implementation may be premature at this time, ESIT will surely be used to guide essential technology specifications in standards development organizations (SDO’s).

Introduction:
The notion of communications channel capacity* as well as the methods, algorithms, and protocols to achieve it have been fundamental questions that have driven the design of wireless communications and will continue to do so.
* Channel capacity is the highest rate at which communications can be made with only a small number of transmission errors.
Communication and information are inherently physical phenomena. Most of the literature, however, abstracts the physics of wave propagation, often treating the generation, transmission, and manipulation of electromagnetic waves as pure mathematical operators.
While mathematical abstractions and engineering approximations are necessary to design advanced or complex communications systems and to gain so-called “engineering insights,” much is lost in understanding the true and physically consistent fundamental limits of wireless communications. The disciplines of information and communications theory, wave propagation, and signal processing are all inter-related and are consistent with the fundamental laws of physics and electromagnetism [1].
…………………………………………………………………………………………………………………
Electromagnetic field theory provides the physics of radio communications, while information theory approaches the problem from a purely mathematical point of view. While there is a law of conservation of energy in physics, there is no such law in information theory. In information theory, when reference is made (as it frequently is) to terms like energy, power, noise, or antennas, it is by no means guaranteed that their use is consistent with the physics of the communication system.
………………………………………………………………………………………………………………….
Emerging communication paradigms and technologies are pushing the boundaries of wave and information manipulation far beyond what was thinkable a few years ago. Among the technologies under evaluation for being integrated in future telecommunication standards, Reconfigurable Intelligent Surfaces (RIS) [2] have been under intense research during the last few years. It is interesting to note that these two technologies put forth a vision of information generation and processing that is not digital-oriented anymore but is analog-oriented and entails the processing of electromagnetic waves either through the scattering objects available in the network or at the end points of communication links.
Editor’s Note: In the past few years, various evaluation and field tests have been delivered to explore the applicability of RIS in future telecommunication standards. For example, ZTE Corporation had conducted outdoor and indoor trials that the deployment of RIS can increase the RSRP by 15 to 35 dB depending on the detail test setup in 2022. NTT Docomo has also performed communication tests based on transparent dynamic meta-surfaces in 2020.
Reconfigurable Intelligent Surfaces:
The basic premise of reconfigurable intelligent surfaces (RIS) is to be able to modify the scattering from objects coated with this technology as one desires. However, modeling such a device as a simple diagonal matrix is neither capacity achieving from a pure information-theoretic standpoint, i.e., assuming that the model being utilized is correct [4], nor strictly correct from an electromagnetic standpoint [5]. Also, the use of such devices just for channel shaping is known not to be capacity achieving [6].
The relationship between information theory and the physics of wave propagation is essential. Understanding these relationships entails a redefinition of the Physical layer in communication systems, which goes beyond the concept of manipulation of bits. The interplay between information theory and physics of wave propagation can only be captured by embedding the wave propagation into the physical layer – a concept known as the “deep physical layer” [10], where electromagnetic field processing is performed using specialized devices.
Electromagnetic Signal and Information Theory (ESIT) Explained:
In order to extend the mathematical notions of information/communication theory and statistical signal processing to incorporate the notion of physics of wave propagation, the term electromagnetic signal and information theory (ESIT) has recently emerged.
ESIT is a broad research field that is concerned with the mathematical treatment and information processing of electromagnetic fields governing the transmission and processing of messages through communication systems. One of the main objectives of ESIT is, for example, the development of communication models that are electromagnetically consistent and that overcome current assumptions in wireless communications, including considering scalar fields, assuming far-field planar wave fronts, and ignoring electromagnetic coupling, as illustrated in the following two figures:
Fig. 1 From far-field planar-wavefronts to near-field spherical wavefronts
Fig. 2 From mutual coupling-free designs to mutual coupling-aware optimization
………………………………………………………………………………………………………………………..
ESIT makes it possible to quantify the ultimate performance limits of wireless communications, by considering realistic electromagnetic models.
Fig. 3. and Fig. 4. show the great benefits of exploiting the mutual coupling at the design stage and the increased number of communication models that can be transmitted in near-field multiple antenna communication channels.
Recent results on the impact of mutual coupling and the fundamental performance limits in the near-field communications can be found in [13] and [14], respectively.
Fig. 3 ESIT: Mutual coupling aware design [11]
Fig. 4 ESIT: Multi-mode communications in line-of-sight [4]
Editor’s Note: Modelling the influence of the near-far field and coupling effects naturally builds up a bridge between the real-world practice and theoretical analysis.

Vodafone and Amazon’s Project Kuiper to extend 4G/5G in Africa and Europe
- Vodafone and Vodacom plan to use Project Kuiper’s low Earth orbit (LEO) satellite constellation to extend the reach of their 4G/5G networks.
- Companies plan to participate in beta testing of Project Kuiper service in 2024.
Vodafone and Project Kuiper, Amazon’s low Earth orbit satellite (LEO) communications initiative, today announced a strategic collaboration through which Vodafone and Vodacom plan to use Project Kuiper’s network to extend the reach of 4G/5G services to more of their customers in Europe and Africa.
Vodafone and Vodacom plan to use Project Kuiper’s high-bandwidth, low-latency satellite network to bring the benefits of 4G/5G connectivity to areas that may otherwise be challenging and prohibitively expensive to serve via traditional fibre or microwave solutions. Project Kuiper will connect geographically dispersed cellular antennas back to the companies’ core telecom networks. This means Vodafone and Vodacom will be able offer 4G/5G services in more locations without the time and expense of building out fibre-based or fixed wireless links back to the core networks.
As part of the collaboration, Amazon plans to partner with Vodafone to roll out Project Kuiper’s high-speed broadband services to unserved and underserved communities around the world. The companies are also exploring additional enterprise-specific offerings to provide businesses with comprehensive global connectivity solutions, such as backup service for unexpected events and extending connectivity to remote infrastructure.
Margherita Della Valle, Vodafone Group Chief Executive, said: “Vodafone’s work with Project Kuiper will provide mobile connectivity to many of the estimated 40% of the global population without internet access, supporting remote communities, their schools and businesses, the emergency services, and disaster relief. These connections will be complemented further through our own work on direct-to-smartphone satellite services.”
“Amazon is building Project Kuiper to provide fast, affordable broadband to tens of millions of customers in unserved and underserved communities, and our flexible network means we can connect places that have traditionally been difficult to reach,” said Dave Limp, Amazon’s senior vice president for devices and services. “Teaming with a leading international service provider like Vodafone allows us to make a bigger impact faster in closing the digital divide in Europe and Africa. Together we’ll explore how we can help our customers get the most value from expanded connectivity, particularly in areas like residential broadband, agriculture, education, healthcare, transportation, and financial services.”
“At Vodacom, our purpose is to connect for a better future, and we work every day to bring more people in Africa online,” said Shameel Joosub, CEO of Vodacom Group. “Collaborating with Project Kuiper gives us an exciting new path to scale our efforts, using Amazon’s satellite constellation to quickly reach more customers across the African continent.”
Vodafone, Vodacom and Project Kuiper will begin deploying services in Africa and Europe as Amazon’s production satellites come online. Amazon is preparing to test two prototype satellites in the coming months before starting to deploy production satellites in 2024. Amazon expects to begin beta testing Project Kuiper services with select customers by the end of 2024, and Vodafone and Vodacom plan to participate in that testing through this collaboration.

ZTE sees demand for fixed broadband and smart home solutions while 5G lags
According to a senior executive, ZTE Corp has seen “tremendous” opportunities due to the increased demand for high-speed internet and smart home solutions globally following the COVID-19 pandemic. That’s despite a slower-than-expected development of 5G outside of China.
“Deployment of 5G technology in overseas markets has been slower than what we previously thought and investments in the field have also lagged behind,” said Chen Zhiping, vice-president of ZTE Corp.
“However, we have seen rapid growth of two sectors in our business – fixed broadband and home network solutions – internationally, especially in the Latin American market.”
The COVID-19 pandemic has pushed up demand for these two types of businesses, as people who were confined to their homes became more reliant on high-speed internet connections and home automation, she said.
“We are actively promoting these two areas of business in Latin America. Besides, the Asia-Pacific region is also where we put great focus on, such as Indonesia, Malaysia and Thailand, as the region has a huge demand for network convergence, network modernization and digitalization,” Chen said.
The Asia-Pacific region is a market from which the company generates most of its overseas revenue, she added.
ZTE posted 60.7 billion yuan ($8.36 billion) in operating revenue in the first half of the year, up 1.5 percent from the year-ago period, according to its interim results announced on Aug 18. Of the total, 17.6 billion yuan, or 29 percent, came from international markets.
Net profit grew 19.9 percent on a yearly basis to 5.47 billion yuan.
“Exploring the domestic market is far from enough for a technology company, whether it is research and development or marketing. We have been committed to the international markets and promoting the globalization of research and development, supply chain and collaboration all along,” she said.
Chen acknowledged that factors such as geopolitical tensions, economic slowdown and a deteriorating business environment in some countries have posed serious challenges to ZTE‘s operations in overseas markets. She stressed that the company had established a sound system of management as well as risk identification and control to deal with potential risks.
On November 225, 2022, the Federal Communications Commission (FCC) voted unanimously to ban U.S. sales of new Chinese telecommunications equipment and devices produced by Huawei and ZTE—as well as to restrict the use of other Chinese-made video surveillance equipment—over national security concerns. The Chinese companies have denied the allegations.
According to a report by German market intelligence platform Statista, the global ICT market is expected to reach $6 trillion in 2023, up from $5.5 trillion last year. China would rank third in global market share with over 11%, following the United States and European Union (EU).

TDC NET with Ericsson launch first 5G Standalone network in Denmark
Danish digital infrastructure provider TDC NET, together with Ericsson, have launched the first 5G Standalone (5G SA) network in Denmark. The transition to high-performance 5G SA technology will enhance the regional 5G ecosystem, accelerate innovation across industries, and unlock exciting possibilities for consumers.
In September 2020, TDC NET went live with the first non-standalone (NSA) 5G network in Denmark, which worked alongside the existing 4G infrastructure provided by Ericsson.
Ericsson press release states: “This milestone signifies a monumental leap forward in connectivity, enabling transformative advancements and placing Denmark at the forefront of technological progress.”
“A 5G Standalone network provides lower latency, higher efficiency, better spectrum utilization, more reliable connectivity, and lower device battery consumption than other networks. It unlocks more use cases for consumers, critical IoT, enterprises and industrial automation. 5G SA also facilitates network slicing benefits for multiple customer segments, offering an infrastructure for businesses to enable, for instance, smart manufacturing and IoT-driven innovation, while giving consumers better and more consistent service experience. It is also a big step forward for communications service providers as it enables a more flexible approach to service creation and provision for subscribers.”
–>Those are all nice features but do any of them represent a monumental leap forward? 5G SA, aka true 5G (vs fake 5G=5G NSA=4G infrastructure/core with a 5G NR RAN) has yet to prove that in its limited global deployments. Where are the new 5G SA revenue streams?
Jakob Dirksen CTO of TDC NET, says: “We were the first to introduce 5G in Denmark and now we are taking the next big step by switching on 5G Standalone. This will offer consumers, enterprises and industries enhanced efficiency, safety, and a range of opportunities across everything from self-driving cars, remote work, healthcare, as well as mission-critical operations by authorities. In addition, 5G Standalone will also enable energy efficiency improvements thanks to more data being transmitted with the same amount of energy and faster access to content.”
One of the key benefits of 5G SA will be improved speed capabilities. Over a 5G SA network, TDC NET and Ericsson have already achieved an impressive 7Gbps downlink peak throughput in a live site environment that has been equipped with Ericsson Radio System products supporting millimeter wave and mid-band spectrum. Enabling New Radio Dual Connectivity (NR-DC) mode through Ericsson’s 5G Core and high modulation scheme have been key to this achievement.
A 5G trial at the Tour de France 2022 in Copenhagen, Denmark used Ericsson Massive MIMO radios on 5G TDD (time division duplex) spectrum. It delivered up to 13 times more data with the same energy consumption compared to LTE FDD (frequency division duplex).
Niclas Backlund, Country Manager for Ericsson Denmark, says: “With the 5G Standalone network, we are now able to accelerate the Danish 5G ecosystem and provide a world-class mobile network with a range of new opportunities for consumers and businesses by enabling slicing, and thereby providing service differentiation. By modernizing legacy networks and then upgrading to 5G, communication service providers can lower operating costs thanks to greater energy efficiency and thus reduce total cost of ownership. And, at the same time, they can future-proof their networks for anticipated higher capacity needs and offer customers value through new services and capabilities.”
In addition, 5G SA uses a dedicated 5G core network, which means that data transmission requires less signaling than with 5G NSA. This is because 5G SA devices do not need to switch between the 4G and 5G core networks, which can reduce latency and improve performance.
The 5G Standalone deployment in TDC´s commercial network is expected to contribute to the service provider’s roadmap towards Net Zero emissions target by 2030, says Ericsson. Also, the 5G SA network was said to signal major overall progress in TDC NET’s technological transformation as it adopts cloud-native software architecture, leading to fast and reliable service innovation for subscribers with service providers using TDC NET’s 5G network, while maintaining improved efficiency and network performance.
