5G SA/5G Core network
GSA 5G SA Core Network Update Report
GSA is tracking the emergence of the 5G SA core network, including the availability of chipsets and devices for customers, plus the testing and deployment of 5G SA networks by public mobile network operators as well as private network operators.
5G SA networks can be deployed in a variety of scenarios: as an overlay for a public 5G non-SA network, as a greenfield 5G deployment for a public network operator without a separate LTE network, or as a private network deployment for an enterprise, utility, education, government or other organization requiring its own private campus network.
GSA has identified 115 operators in 52 countries and territories worldwide that have been investing (?) in public 5G SA networks in the form of trials, planned or actual deployments (see Figure 1.). This equates to 21.4% of the 535 operators known to be investing in 5G licenses, trials or deployments of any type.
At least 36 operators in 25 countries and territories are now understood to have launched or deployed public 5G SA networks, two of which have only soft-launched their 5G SA networks.
NOTE: Incredibly, that’s a DECREASE from GSA’s June 5G SA report which stated “GSA has catalogued 41 operators as having deployed or launched 5G standalone (SA) in public networks.”
Also, 19 cellular network operators have been catalogued as deploying or piloting 5G SA for public networks, and 29 as planning to deploy or evaluating, testing or trialing the technology.
Several organizations are testing, piloting or deploying 5G SA technologies for private networks. As of May 2024, 66 (just over 13% of total cellular private networks) organizations are known to be working with 5G SA core networks. These organizations include manufacturers, academic institutions, commercial research institutes, construction, communications and IT services, rail and aviation industries.
The number of 5G SA devices as a percentage of all 5G devices announced has been steadily increasing. They accounted for 35.6% of 5G devices in December 2019, 49.7% in December 2020 and 54.6% in December 2021 and a large increase to 81.8% in December 2022. As of June 2023, they account for 85.8%.
Software upgrades are almost always needed to enable 5G SA capability for existing 5G devices. There is a range of form factors to cater for different users, including modules for equipment manufacturers and vendors; customer-premises equipment (CPE), routers and gateways for enterprise or industrial customers or their systems integrators; CPE for home and business broadband; phones; and battery-operated hot spots for portable services.
Smartphones make up over half (59.0%) of the announced 5G devices with stated 5G SA support (1,034 phones), followed by fixed wireless access CPE (246) and modules (220).
Spectrum Support in 5G SA Devices:
Selected sub-6 GHz frequencies are increasingly well supported in 5G SA devices. The pattern of most-supported bands in sub-6 GHz 5G SA devices largely matches the pattern for most-supported bands across all 5G devices, with C-band, 2.6 GHz, 2 GHz, 1.8 GHz and 700 MHz.
Sub-6 GHz support by band, announced 5G SA devices, most-supported bands by most devices. Support for millimeter wave is not yet common.
Chipsets are being developed to support this capability — GSA has currently only catalogued eight chipsets specifically supporting 5G SA in millimeter-wave spectrum (eight mobile processors and platforms). 320 393 397 421 449 519 739 741 743 817 846 979 1,025 1,115 1,183 1,257 1,309 1,444 1,465 n48 n25 n66 n71 n12 n2 n20 n40 n79 n38 n7 n8 n5 n3 n28 n77 n1 n41 n78 We can expect support for spectrum bands above 6 GHz to increase in the future, as these bands are being promoted as an option for deployment of private 5G networks by regulators in various countries, as well as being promoted as capacity bands for high-traffic locations in public networks.
Summary:
The market is seeing the emergence of a strong 5G SA ecosystem with chipsets, devices of many types and users of public as well as private networks. We can expect to see the market go from strength to strength.
–>This author opines the 5G SA market is going from nowhere to no place!
As it does, GSA will continue to track its evolution and will be looking out for important new trends as they emerge.
Topics likely to become more important in the coming year in this context include 5G carrier aggregation in SA networks, ultrareliable low-latency communications (can’t be accomplished till 3GPP Release 16 URLLC in the RAN spec has been completed and performance tested) capabilities to support machine-to-machine connections in 5G SA systems, increasing support for millimeter-wave connections, network slicing in 5G networks and the introduction of VoNR in 5G SA networks.

GSM 5G-Market Snapshot Highlights – July 2023 (includes 5G SA status)
5G SA networks (real 5G) remain conspicuous by their absence
ABI Research: Expansion of 5G SA Core Networks key to 5G subscription growth
Dell’Oro: RAN Market to Decline 1% CAGR; Mobile Core Network growth reduced to 1% CAGR
According to a newly published forecast report by Dell’Oro Group,the Radio Access Network (RAN) market is done expanding for now. Following the 40% to 50% ascent between 2017 and 2021, RAN revenues flattened out in 2022 and these trends extended to 1Q 2023.
“Even if it is early days in the broader 5G journey, the challenge now is the comparisons are becoming more challenging in the more mature 5G markets and the upside with the slower-to-adopt 5G regions is not enough to extend the growth streak,” said Stefan Pongratz, Vice President at Dell’Oro Group.
“Meanwhile, growth from new revenue streams including Fixed Wireless Access and enterprise LTE/5G is not ramping fast enough to change the trajectory. With 5G-Advanced not expected to trigger a new capex cycle, the question now is no longer whether RAN will grow. The question now is, rather, how much will the RAN market decline before 6G comes along?” Pongratz added.
Additional highlights from the Mobile RAN 5-Year July 2023 Forecast Report:
- Global RAN is projected to decline at a 1 percent CAGR over the next five years.
- The less advanced 5G regions are expected to perform better while the more developed 5G regions, such as North America and China, are projected to record steeper declines.
- LTE is still handling the majority of the mobile data traffic, but the focus when it comes to new RAN investments is clearly on 5G. Even with the more challenging comparisons, 5G is projected to grow another 20 percent to 30 percent by 2027, which will not be enough to offset steep declines in LTE.
- With mmWave comprising a low single-digit share of the RAN market and skepticism growing about the MBB business case, it is worth noting that our position has not changed. We still envision that the mmWave spectrum will play a pivotal role in the long-term capacity roadmap.
……………………………………………………………………………………………………………………….
Separately, Dell’Oro again lowered its forecasts for the Mobile Core Network market (which is now 5G SA core network), this time citing a slowdown in customer growth. It now predicts that the worldwide market for mobile core networks will expand at a CAGR of 1% over the next five years, having previously forecast a 2% CAGR as recently as January.
“We have reduced our forecast for the third consecutive time, primarily caused, this time, by an expected slowdown in subscriber growth,” said Dave Bolan, Research Director at Dell’Oro Group.
Dave said that Dell’Oro has reduced its expectations for the Multi-Access Edge Computing (MEC) market (which requires 5G SA core network). It now anticipates MEC will have a CAGR of 31%, noting that commercially-viable enterprise applications are taking much longer to come to fruition than many had hoped.
“Mobile Network Operators (MNOs) are concerned about inflation, a possible recession, and political conflicts. They are therefore being restrained in their capital expenditures, another factor weighing in on a more conservative forecast,” said Bolan. “As we continue refining our count of MNOs that have launched 5G Standalone (5G SA) eMMB networks, we note that only 4 MNOs have commercially deployed new 5G SA networks compared to six in the first half of 2022,” he added.
Additional highlights from the Mobile Core Network & Multi-Access Edge Computing 5-Year July 2023 Forecast Report:
- Year-over-year MCN revenue growth rates are projected to be flat in 2026 and turn negative in 2027.
- The North America and China regions are expected to have negative CAGRs, while Europe, Middle East, and Africa (EMEA), and Asia Pacific excluding China regions are expected to have the highest positive CAGRs.
Vodafone became one of those first-half 2023 launches, when it brought 5G Ultra to market in the UK in late June. In its latest Mobility Report, published around the same time, Ericsson noted that while around 240 telcos have launched commercial 5G services, only 35 of them have brought standalone 5G to market.
That should bode well for the mobile core market, and indeed it is faring better than the RAN space, in growth potential terms, at least.
Nonetheless, Dell’Oro predicts that year-on-year growth rates in mobile core network revenues will be flat by 2026 and turn negative the following year.

Heavy Reading Survey: 5G services require network automation
Heavy Reading’s 2023 5G Network Analytics and Automation Operator Survey aims to help the industry better understand the status of network analytics and automation and provide insights into operators’ strategies. (To download a copy, click here.) At the start of the survey, one question looks to understand which 5G services network operators believe to be the most valuable in supporting revenue growth.
Editor’s NOTE: It’s important to understand that ALL 5G SERVICES/FEATURES (such as network slicing) require a 5G SA core network rather than 5G NSA which uses 4G-LTE infrastructure for everything other than the 5G NR RAN.
……………………………………………………………………………………………………………………………
The table below shows the weighted average scores across several 5G services, with operators ranking “mobile broadband subscriber growth/retention/high prices” first and ahead of the other options.
Enhanced mobile broadband (eMBB) is the anchor service for 5G NSA and generates nearly all 5G revenue today. This scoring infers that operators are keen to grow their core businesses, which will involve greater efficiencies and new mobile packages that offer superior or premium features at an added cost.
“Private 5G” and “network slicing” rank second and third, respectively. Heavy Reading expects their importance and popularity to increase as additional operators deploy 5G SA and can support full autonomy. “Performance SLAs for enterprise services” is currently the lowest ranking (fifth) of all service choices but is likely to be a valuable market, especially for network slicing and private 5G.
“Connected devices (e.g., cars, watches, other IoT devices)” ranks just above performance SLAs in fourth. Internet of Things (IoT) is a sizeable market within 4G, but the massive machine-type communications (mMTC) use case has yet to be realized in 5G, as technologies such as RedCap remain underdeveloped.
Smaller network operators have a different opinion than larger operators on the revenue growth question.
For mobile operators with less than 9 million subscribers, private 5G ranks first. This result perhaps indicates that smaller operators feel they are already exploiting eMBB services and see little scope for further revenue growth with 5G SA.
Which services are the most attractive for 5G revenue growth in your organization? (Rank in order, where 1 = the most attractive)
Given the survey results above and the desire for operators to grow their revenue and retain customers, it is evident that automation will play a fundamental role in future 5G services underpinning cost efficiencies and quality of service. Service diversity and the 5G disaggregated cloud native infrastructure will mandate automation across the network (i.e., provisioning, testing, operation, fault resolution and maintenance), specifically for the following aspects:
Automated configuration: Automation tackles the scale and complexity of administration, management and lengthy configuration across large networks with multiple service solutions (e.g., private networks, network slicing, performance SLAs, etc.), offering significant time savings over manual effort.
- End-to-end 5G monitoring and visibility: 5G network visibility requires a dynamic and layered approach to monitor 5G cloud infrastructure, orchestration/containerized environments and the network domains and services. Service insights and SLA monitoring will be more granular. Examples include network slicing visibility per slice, user, session, location, etc., across KPIs like latency, jitter, packet drop and data rate.
- Network probes and testing: Active test agents provide near real-time visibility, making them better equipped to monitor dynamic cloud native environments and workload changes than more traditional reactive methods.
- Lifecycle and test management: Automated software deployment cycles (CI/CD) will be critical due to the increased cadence of software updates across virtual machines or cloud native deployments. In addition, automating network and service testing could enable the validation of services and configuration while assessing the perceived end-user quality of service.
- Artificial intelligence/machine learning (AI/ML): These technologies will contribute heavily to automated processes, optimization and efficiencies, with AIOps processes assuring the network and its services. For example, AI/ML can help forecast network resources, user mobility patterns, RAN optimization, security anomaly prevention, fault prediction, etc.
Operators are highly motivated to deliver advanced services and drive business growth and revenue to recoup the costs of their significant 5G spectrum and network investments. However, supporting a diverse and evolving portfolio of 5G network services will require automation to provide service visibility, efficiencies and network performance excellence.

Swisscom, Ericsson and AWS collaborate on 5G SA Core for hybrid clouds
Orange Business tests new 5G hybrid network service in France
Orange Business said that it has carried out tests of a new 5G service called “Mobile Private Network hybrid“at its office in Arcueil (Ile-de-France region). The telco claims the hybrid private network has several applications and is able to connect industrial equipment, tablets and autonomous vehicles, among other end points. It cited the example of ports as an area particularly suitable for hybrid network deployments.
Orange said it is “actively investing in the construction” of hybrid 5G networks in France. Its two units have been “constantly innovating to continue to develop services and use [cases],” the company added.
The new 5G service has been tested with a router from Ericsson owned Cradlepoint which is connected to both networks simultaneously and assigns data flows to the appropriate network based on predefined use cases and the application being used. The Cradlepoint router supports 5G SA and network slicing technology for business premises, with a hardened version available for industrial settings.
The test project hosted two use cases in two network slices, running on a laptop (“behind the router”): transmission of a video feed to the cloud on the public network to support a remote assistance use case, and an edge-based supervision application for an industrial process where all the data circulated on the private network. “The separation of data flows is complete from the application on the terminal to the core network.”

The network is operated by Orange in full and does not require the use of multiple SIM cards. Companies can use the solution for both critical and non-critical applications, with data flows isolated from the application on the terminal all the way to the core, and service quality adapted to each application. The company says it relies on local break-out technology, which allows for local routing of data flows, to offer stable low latencies. Orange also says the private network guarantees performance and offers higher data security than the public network.
Orange is one of few European operators that have started rolling out 5G SA networks, it has not yet officially launched one in France. In March, it announced it would start offering 5G SA in a handful of Spanish cities later this year. The telco will rely on Ericsson’s core technology, which will also be used in Belgium, Luxembourg and Poland.

Samsung-Mediatek 5G uplink trial with 3 transmit antennas
Samsung Electronics and MediaTek have successfully conducted 5G standalone (SA) uplink tests, using three transmit (3Tx) antennas instead of the typical two, to demonstrate the potential for improved upload experiences with current smartphones and customer premise equipment (CPE).
Until recently, most talk about 5G SA industry firsts have focused on the downlink. However, the demands on uplink performance are increasing with the rise of live streaming, multi-player gaming and video conferences. Upload speeds determine how fast your device can send data to gaming servers or transmit high-resolution videos to the cloud. As more consumers seek to document and share their experiences with the world in real-time, enhanced uplink experiences provide an opportunity to use the network to improve how they map out their route home, check player stats online and upload videos and selfies to share with friends and followers.
While current smartphones and customer premise equipment (CPEs) can only support 2Tx antennas, this industry-first demonstration validated the enhanced mobile capability of 3Tx antenna support. This approach not only improves upload speeds but also enhances spectrum and data transmission efficiency, as well as overall network performance.
The test was conducted in Samsung’s lab, based in Suwon, Korea. Samsung provided its industry-leading 5G network solutions, including its C-Band Massive MIMO radios, virtualized Distributed Unit (vDU) and core. The MediaTek test device featuring its new M80-based CPE chipset began with one uplink channel apiece at 1,900MHz and 3.7GHz, but added an extra uplink flow using MIMO on 3.7GHz. Both companies achieved a peak throughput rate of 363Mbps, an uplink speed that is near theoretical peak using 3Tx antennas.

“We are excited to have successfully achieved this industry breakthrough with MediaTek, bringing greater efficiency and performance to consumer devices,” said Dongwoo Lee, Head of Technology Solution Group, Networks Business at Samsung Electronics. “Faster uplink speeds bring new possibilities and have the potential to transform user experiences. This milestone further demonstrates our commitment to improving our customers’ networks using the most advanced technology available.”
“Enhancing uplink performance using groundbreaking tri-antenna and 5G UL infrastructure technologies will ensure next-generation 5G experiences continue to impress users globally,” said HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek. “Our collaboration with Samsung has proved our combined technical capabilities to overcome previous limits, enhancing network performance and efficiency, opening up new possibilities for service providers and consumers to enjoy faster and more reliable 5G data connectivity.”
“With demands on mobile networks rising, enhancing upload performance is essential to improving consumer and enterprise connectivity, as well as application experiences,” said Will Townsend, VP & Principal Analyst at Moor Insights & Strategy. “Samsung and MediaTek have achieved an important 5G Standalone milestone in a demonstration which underscores a tangible network benefit and does so in a way that can help operators maximize efficiency.”
Samsung has pioneered the successful delivery of 5G end-to-end solutions, including chipsets, radios and core. Through ongoing research and development, Samsung drives the industry to advance 5G networks with its market-leading product portfolio, from virtualized RAN and Core to private network solutions and AI-powered automation tools. The company currently provides network solutions to mobile operators that deliver connectivity to hundreds of millions of users worldwide.

5G SA networks (real 5G) remain conspicuous by their absence
According to a May 2023 report from the Global mobile Suppliers Association (GSA), just 35 network operators in 24 countries and territories “are now understood to have launched or deployed public 5G SA networks.” That’s out of approximately 240 service providers which have now launched commercial 5G services, as per the recent Ericsson Mobility Report.
Dell’Oro’s Dave Bolan said, “Currently we count 43 live 5G SA networks for eMMB [enhanced mobile broadband]. For 2023, four [mobile network operators] have launched 5G SA networks,” he added. It should be noted that Dell’Oro doesn’t factor in fixed wireless access (FWA) or private 5G networks in its SA totals.
In Europe, Vodafone UK and Telefónica Spain join what remains a small set of network operators that have launched 5G SA, including Orange Spain and Vodafone Germany. Spain should provide an interesting study of what happens when two rival operators launch 5G SA service.
There are some glimmers of hope that 5G SA launches will accelerate soon. GSA (aka GSMA) has identified at least 1,063 announced devices with declared support for standalone 5G in sub-6GHz bands, 864 of which are commercially available. Furthermore, it said 116 operators in 53 countries and territories are now investing in 5G SA, including those that have actually deployed a public network. “This equates to 22.1% of the 524 operators known to be investing in 5G licenses, trials or deployments of any type,” the GSA said.
Separately, analysts say that 5G SA branding by network operators is quite confusing (we agree). Vodafone UK’s decision to use 5G Ultra for its 5G SA branding vs Telefonica using 5G+ are examples of that.
Gabriel Brown of Heavy Reading said, “customers don’t really know what it means, other than it denotes some form of technical advance.” He points out that 5G SA “requires a lot of investment and deep engineering expertise; this makes it a useful proxy for network quality. Operators need to take all the technical marketing opportunities they can get.”
“What happens when BT launches? Are they going to call it 5G+ or 5G Super Ultra or something like that? That’s going to make it even more confusing,” said Kester Mann, an analyst with CCS Insight. At the same time, he agrees that 5G standalone is a significant network upgrade and it makes sense that operators would want to gain a marketing edge over rivals that have yet to launch the service.
Notably, neither Vodafone nor Telefónica is charging extra for the more advanced 5G service, and both have focused on the improved speeds and reliability it will bring. They also emphasize eco-friendly aspects, such as lower energy consumption. However, Mann questioned Vodafone’s claim that customers with an eligible 5G Ultra device can expect up to 25% longer battery life. “Twenty-five percent faster than what?” he asked. “It’s a bit unclear.” However, such a claim would certainly be welcome news to consumers. “In a lot of our consumer research, battery life comes out as one of the common bugbears among people using mobile phones,” said Mann.
In the U.S., T-Mobile is the only network operator that’s deployed a 5G SA network. AT&T and Verizon have been talking about it for years, but the time frame for deployment has been pushed back several times.
Deloitte Global said it expects the number of mobile network operators investing in 5G SA networks via trials, planned deployments or rollouts to grow from more than 100 operators in 2022 to at least 200 by the end of this year.
One reason why there are relatively few 5G SA networks deployed is there are no implementation standards. 3GPP 5G Architecture specs, rubber stamped by ETSI, provide several options to realize a 5G cloud-native core network which leads to different implementations. 3GPP decided NOT to liaise their 5G non-radio aspects specs (including 5G Architecture and 5G Security) to ITU-T.
Here are the key 3GPP 5G system specs:
- TS 22.261, “Service requirements for the 5G system”
- TS 23.501, “System architecture for the 5G System (5GS)”
- TS 23.502 “Procedures for the 5G System (5GS)”
- TS 32.240 “Charging management; Charging architecture and principles”
- TS 24.501 “Non-Access-Stratum (NAS) protocol for 5G System (5GS); Stage 3”
The latest 3GPP 5G Architecture spec is System architecture for the 5G System (5GS) (3GPP TS 23.501 version 17.9.0 Release 17), published by ETSI on July 5, 2023.
Source: 3GPP
Hence, the ITU JCA on IMT2020 and Beyond is dependent on other organizations for inputs to their roadmap. “The scope of JCA-IMT2020 is coordination of the ITU-T IMT-2020 standardization work with focus on non-radio aspects and beyond IMT2020 within ITU-T and coordination of the communication with standards development organizations, consortia and forums also working on IMT2020 and beyong IMT-2020 related standards.”

Telefónica launches 5G SA in >700 towns and cities in Spain
Telefónica has followed Orange with the official launch of a 5G standalone (SA) network in more than 700 towns and cities throughout Spain. The service is branded Movistar 5G+ even though it is just 3GPP defined real 5G (with its own core network , rather than 5G NSA which uses LTE core network). The new Telefónica 5G SA network uses Ericsson and Nokia network equipment. Huawei has been excluded from it because the European Commission wants to ban Huawei in the EU for its alleged espionage work for the Chinese government.
Telefonica said its 5G NSA service in the 700 MHz band is currently available to around 85 percent of the Spanish population across 2,200 municipalities. The Spanish operator also uses the 3.5 GHz band for 5G and invested EUR 20 million to secure the maximum possible 1 GHz of spectrum in the 2.6 GHz band.
“Movistar customers will be able to enjoy 5G+ automatically and at no additional cost both in large cities and in small municipalities thanks to a highly capillarity deployment that will allow ultra-fast speeds and very low latency to be obtained in practically all of Spain,” the company explained in a statement.
The launch of 5G+, which offers greater coverage and browsing speeds of up to 1,600 megabits per second (Mbps), will take place within the scope of Movistar’s deployment in the 3,500 MHz band. In practice, 5G+ translates into better mobile experience in content downloads at the speed of fiber optics, streaming High quality and uninterrupted gaming. It also offers greater coverage in crowded spaces such as a sporting event or a music concert, according to Telefónica.
Movistar currently covers a total of 11 cities with 5G SA: Madrid, Barcelona, Malaga, Seville, Palma de Mallorca, Las Palmas de Gran Canaria, Ávila, Segovia, Castellón, El Ferrol and Vigo. The goal for the end of the year is to have “extensive 5G SA coverage in most cities with more than 250,000 inhabitants,” as well as in smaller towns, so that the capillarity of the service continues to be consolidated. However, in order to enjoy this service it is necessary to have a mobile that supports 5G SA. For the moment, Movistar has the new Xiaomi terminals to which new brands will be added.
Gabriel Brown, principal analyst at Heavy Reading, notes that Movistar operates the biggest network in Spain and has the largest number of live 3.5GHz sites, according to the independent AntenasMoviles website.
Said deployment is completed with the coverage in the 700 MHz band that Movistar has been offering since last year and currently reaches more than 2,200 municipalities, with advantages such as improved indoor coverage. The so-called low band is complemented in 5G with that of 3,500 MHz, ideal for services that require a user experience at a very high transmission speed, both for rural areas and large urban centers. In this way, Movistar already offers 5G coverage to more than 85% of the population, reports the company.–
Orange leads 5G SA coverage as it already reaches more than twenty cities that cover 30% of the population in Spain. In the case of Vodafone and MásMóvil, 5G SA is expected to be available before March 2024.
Heavy Reading’s Brown said, “It will be interesting to see if this gives it an edge in SA. Orange Spain, meanwhile, says it will launch network slicing before the end of the year.”

Samsung bets on software centric network architectures supporting virtualized services
Kim Woojune, President and General Manager of Samsung Networks [1.] asserted that software capabilities will change the telecommunications landscape, as the South Korean tech giant bets on virtualized services. Kim said that future networks will be transformed more into software-centric architecture, versus the hardware-based networks the world has built and relied upon for about 150 years.
Note 1. Kim was appointed president and general manager of Samsung’s Networks business in December 2022
“Software has become a key driver of innovation, and this transition to software is also a natural shift in the networks industry,” Kim said in a speech at Nikkei’s Future of Asia forum. “Software brings more flexibility, more creativity and more intelligence,” he added.
Kim said the next transition in the network business has already started, as global telecom operators such as Verizon in the U.S., and KDDI and Rakuten in Japan are building their virtualized networks.
In February, Samsung announced that it was selected by KDDI to provide its cloud-native 5G Standalone (SA) Core network for the operator’s commercial network across Japan. The company said that this will usher in a new generation of services and applications available to KDDI’s consumers and enterprise customers — including smart factories, automated vehicles, cloud-based online gaming and multi-camera live streaming of sports events. Samsung and KDDI also successfully tested network slicing over their 5G SA Core network.
The Samsung executive asked global governments to embrace the shift, saying their role “should be to maximize the benefit of this extra use.”
Samsung is also winning contracts with cable providers, like Comcast, where it’s working to deploy 5G RAN solutions to support its efforts to deliver 5G access to consumers and business customers in the U.S. using CBRS and 600 MHz spectrum, Kim noted. Comcast is the first operator to use Samsung’s new 5G CBRS Strand Small Cell, a compact and lightweight solution designed to be installed on outdoor cables. It consists of a radio, baseband, cable modem and antennas, all in one form factor. The solution is also equipped with Samsung’s in-house designed chipset, a second-generation 5G modem SoC, which delivers increased capacity and performance.

ABI Research: Expansion of 5G SA Core Networks key to 5G subscription growth
The number of 5G subscriptions will surge from 934 million in 2022 to 3.1 billion in 2027 -a Compound Annual Growth Rate (CAGR) of 27% – according to a study from ABI Research. Further, 5G traffic is forecast to increase from 293 Exabytes (EB) in 2022 to 2,515 EB in 2027, at a CAGR of 54%.
ABI’s forecast is largely based on an increase in 5G Core (5GC) networks. To date, more than 35 5GC networks are operating in 5G standalone (SA) mode. 5GC is expected to lead to a growth in devices connected to the network and the traffic routed through it.
“5GC holds potential for operators to monetize further existing cellular connectivity for traditional mobile broadband (MBB) use cases but also offers scope for operators to expand cellular capabilities in new domains. Additionally, 5GC also offers innovation potential for committed telcos to establish new operating models for growth outside of the consumer domain,” explains Don Alusha, Senior Analyst, 5G Core and Edge Networks, at ABI Research.
5GC presents Communications Service Providers (CSPs) with a fluid and dynamic landscape. In this landscape, there is no static offering (requirements constantly change), no uniform offering (one shoe does not fit all), and no singular endpoint (one terminal with multiple applications). 5GC guides the industry into edge deployments and topologies. CSPs step out of the four walls of either their virtual Data Center (DC) or physical DC to place network functionality and compute as close to their customers as possible. This constitutes decentralization, a horizontal spread of network assets and technology estate that calls for a ‘spread’ in the operating model.
The shift from a centralized business (e.g. with 4G EPC) to a decentralized business (5G SA core network) stands to be a significant trend in the coming years for the telecoms industry. Against that backdrop, the market will demand that CSPs learn to drive value bottom-up. “What customers need” is the starting point for companies like AT&T, BT, Deutsche Telekom, Orange, and Vodafone. In other words, in this emerging landscape, there will be enterprise-specific, value-based, and niche engagements where the business strategy sets the technology agenda. So, it is rational to conclude that a “bottom-up” approach may be required to deliver unique value and expand business scope. That said, CSPs may be better equipped to drive sustained value creation if they learn to build their value proposition, starting from enterprise and industrial edge and extending to core networks.
“A 5G cloud packet core can potentially unlock new transactions that supplement existing volume-centered modus operandi with a local, bottom-up value play for discrete engagements. But the power of a bottom-up model is not enough. To monetize a 5G cloud packet core at scale, some of the existing top-down intelligence is needed too. Learning how to operate in this hybrid top-down and the emerging bottom-up, horizontally stratified ecosystem is a journey for NTT Docomo, Rakuten Mobile, Singtel, Softbank, and Telstra, among other CSPs. In the impending cellular market, an effective and efficient operating model must contain both control and lack of control, both centralization and decentralization and a hybrid of bottom-up plus some of the ‘standard’ top-down intelligence. The idea is that CSPs’ operating model should flexibly fit and change in line with new growing market requirements, or new growth forays may hit a roadblock,” Alusha concludes.
Editor’s Note:
It’s critically important to understand that the 3GPP defined 5G core network protocols and network interfaces enable the entire mobile system. Those include call and session control, mobility management, service provisioning, etc. Moreover, the 3GPP defined 5G features can ONLY be realized with a 5G SA core network. Those include: Network Automation, Network Function Virtualization, 5G Security, Network Slicing, Edge Computing (MEC), Policy Control, Network Data Analytics, etc
Figure 1: Overview of the 5G system
The 5GC architecture relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities. Via interfaces of a common framework, any given NF offers its services to all the other authorized NFs and/or to any “consumers” that are permitted to make use of these provided services. Such an SBA approach offers modularity and reusability.

The 5G SA architecture can be seen as the “full 5G deployment,” not needing any part of a 4G network to operate.
Finally, 3GPP has not liased their 5G system architecture specifications to ITU-T so there are no ITU-T standards for 5G SA Core Network or any other 5G non-radio specification. Instead, 3GPP sends their specs to ETSI which rubber stamps them as “ETSI standards.”

AT&T touts 5G advances; will deploy Standalone 5G when “the ecosystem is ready”- when will that be?
Backgrounder -5G SA Core Network:
5G SA core is the heart of a 5G network, controlling data and control plane operations. The 5G core aggregates data traffic, communicates with UE, delivers essential network services and provides extra layers of security, and all 3GPP defined 5G features and functions. There are no standards for implementation of 3GPP defined 5G SA core network architecture, which is said to be a service based architecture, recommended to be “cloud native.” Here are the key 3GPP 5G system specs:
- TS 22.261, “Service requirements for the 5G system”
- TS 23.501, “System architecture for the 5G System (5GS)”
- TS 23.502 “Procedures for the 5G System (5GS)”
- TS 32.240 “Charging management; Charging architecture and principles”
- TS 24.501 “Non-Access-Stratum (NAS) protocol for 5G System (5GS); Stage 3”

AT&T Yet to Deploy 5G SA Core Network but is “charging forward to advance 5G SA ecosystem readiness:
It’s been a long wait for AT&T’s 5G SA core network, which is required to realize ALL 5G functions defined by 3GPP, including network slicing, network virtualization, security, and edge computing (MEC).
- The U.S. mega network operator initially said they would launch 5G SA core network in 2020 but that never happened.
- On June 30, 2021, AT&T said their mobile network traffic will be managed using Microsoft Azure technologies. “The companies will start with AT&T’s 5G core, the software at the heart of the 5G network that connects mobile users and IoT devices with internet and other services.” Almost two years later, that hasn’t happened either!
- In an April 18, 2022 blog post on the company’s website, AT&T now says they are “Taking 5G to the Next Level with Standalone 5G.” AT&T has said that they “plan to deploy Standalone 5G when the ecosystem is ready, and AT&T is charging forward to advance 5G SA ecosystem readiness. Businesses and developers will be some of the first to take advantage of the new technologies standalone 5G enables as we continue to move from research & development to their deployment.”
However, AT&T did not provide a date or even a timeframe when its 5G SA core network would be deployed. Instead, the telco lauded several 5G advances they’ve recently made. Those include:
1. Completed the first 5G SA Uplink 2-carrier aggregation data call in the U.S.
Carrier aggregation (CA) means we are combining or “aggregating” different frequency bands to give you more bandwidth and capacity. For you, this means faster uplink transmission speeds. Think of this as adding more lanes in the network traffic highway.
The test was conducted in our labs with Nokia’s 5G AirScale portfolio and MediaTek’s 5G M80 mobile test platform. AT&T aggregated their low-band n5 and our mid-band n77 spectrum. Compared to the low-band n5 alone, AT&T realized a 100% increase in uplink throughput by aggregating the low-band n5 with 40MHz of AT&T’s mid-band n77. Taking it a step further, AT&T achieved a 250% increase aggregating 100MHz of n77. The bottom line: AT&T achieved incredible upload speeds of over 70 Mbps on n5 with 40MHz of n77 and over 120 Mbps on n5 with 100MHz of n77.
2. Using a two-layer uplink MIMO on time division duplex (TDD) in our mid-band n77. MIMO combines signals and data streams from multiple antennas (“vehicles”) to improve signal quality and data rates. This feature will not only improve uplink throughput but also enhance cell capacity and spectrum efficiency.
3. Last fall, AT&T completed a 5G SA four component carrier downlink call by combining two FDD carriers and two TDD carriers. These capabilities allow AT&T devices to aggregate our mid-band n77 in the C-Band and 3.45GHz spectrum ranges. Compared with low band and mmWave spectrum, mid-band n77 provides a good balance between coverage and speed. This follows the 5G SA three component carrier downlink feature that we introduced last year to 2022 AT&T Flagship devices which combines one frequency division duplex (FDD) carrier and two TDD carriers.
4. In the coming months, AT&T will enable 5G New Radio Dual Connectivity (NR-DC), aggregating our low and mid-band spectrum with our high-band mmWave spectrum on 5G SA. Our labs have achieved 5G NR-DC downlink throughput speeds of up to 5.3Gbps and uplink throughput speeds of up to 670Mbps. This technology will help provide high-speed mobile broadband for both downlink and uplink in stadiums, airports, and other high-density venues.
5. Here are some features that are on the horizon for 5G SA (how far away is the horizon?):
- Specialized Network Services – think network slicing, precision location, private routing, etc. – for tailored network solutions to meet specific user requirements;
- Non-terrestrial network solutions to supplement coverage in remote locations ; and
- Reduced capability 5G (RedCap) for a new generation of 5G capable wearables, industrial IoT or wireless sensors and other small form factor consumer devices.
In conclusion, AT&T’s Jason Sikes wrote, “The 5G SA ecosystem is rapidly evolving, with new technologies and capabilities being introduced to set the foundation for next generation applications and services.” Yet no information was provided on the status of AT&T’s 5G SA network running on Microsoft Azure cloud technology!

In the U.S., T-Mobile launched 5G SA core network nationwide last year, while Verizon began shifting its own traffic onto its 5G SA core in 2022. More recently, Verizon officials have begun hinting at interest in selling SA-powered network slices to public safety customers and others.
At the close of 2022, Dell’Oro identified 39 MNOs (Mobile Network Operators) that have commercially launched 5G SA eMMB networks. “Reliance Jio, China Telecom-Macau, and Globe Telecom were new MNOs added to the list of 39 MNOs launching 5G SA eMMB networks in the fourth quarter of 2022. Reliance Jio has announced a very aggressive deployment schedule to cover most of India by the end of 2023. In addition, AT&T and Verizon plan large expansions to their 5G SA coverage in 2023, raising the projected Y/Y growth rate for the total MCN and MEC market for 2023 higher than 2022,” said Dave Bolan, Research Director at Dell’Oro Group.
