Spark New Zealand partnering with Lynk Global to offer a satellite-to-mobile service
Spark, the leading telco in New Zealand, announced it is collaborating with Lynk Global to offer a satellite-to-mobile service, aiming to enhance connectivity for its customers. Later this year, selected customers will be offered a free trial of the service.
The satellite-to-mobile service will enable periodic text messaging throughout the day during the initial trial. However, as more commercial satellites are deployed, Spark intends to expand the service in 2024 to offer more regular connectivity. The ultimate goal is to provide voice and data services to customers once they become reliably available.
Spark said while satellite coverage cannot reach 100 percent due to the requirement of a clear line of sight to the sky, it offers an additional layer of resilience, especially in light of increasingly severe and frequent weather events caused by climate change. By leveraging satellite connectivity, Spark aims to extend its network reach to areas that are currently underserved by traditional mobile coverage.
According to the Spark press release, the trial period will provide an opportunity to refine and enhance the service in alignment with the increasing number of satellites in orbit. Integration into Spark’s network and regulatory approval are also essential steps before the service can be officially launched.

The collaboration with Lynk Global and the existing partnership with Netlinkz, which aims to provide satellite broadband services, are part of Spark’s broader strategy to leverage satellite technology as part of its connectivity offering to customers. Spark says it is actively working with various partners to expand the range of services it can deliver.
In a separate announcement last week, Spark revealed its partnership agreement with Netlinkz to provide Starlink business-grade satellite broadband to customers later this year. This initiative follows ongoing trials with a select number of New Zealand businesses.
Spark Product Director, Tessa Tierney, said, “We believe satellite has an important role to play in connecting Aotearoa New Zealand. While satellite can’t provide 100% coverage – as you need a clear line of sight to the sky to get connected2 – it certainly adds an additional layer of resilience, particularly now, as we face increasingly severe and frequent weather events due to climate change. And once there are more satellites launched and the service is available more broadly, it will allow our mobile customers to start to use their phones in more areas that aren’t reached by traditional mobile coverage.”
“We know that our customers will be eager to start using satellite messaging, but the technology is still evolving, so the service and experience will improve and expand as the number of satellites in the sky increases. That’s why we’ve chosen to trial this technology with some of our customers first, to make sure we can offer a great product to our customers when we make it widely available. We also need to integrate the technology into our network and achieve regulatory approval to launch the service. But we are excited to see the possibilities this creates for New Zealanders and will be working hard to make it widely available as soon as we can.
“This partnership with Lynk, and our partnership with NetLinkz to offer a satellite business connectivity service are part of Spark’s broader strategy to use satellite as a part of our connectivity offer to customers. We are continuing to work with these and other potential partners to broaden the services Spark can offer.”
Spark’s introduction of satellite-to-mobile services and business-grade satellite broadband underscores its commitment to enhancing connectivity options for customers across the country, particularly in underserved areas. Spark said further details, including eligibility criteria and timelines, will be disclosed in the coming months.

ACSI report: AT&T, Lumen and Google Fiber top ranked in fiber network customer satisfaction
AT&T is #1 in customer satisfaction for fiber optic network providers, according to a new report from the American Customer Satisfaction Index (ACSI). ACSI’s report rates consumer satisfaction for both fiber and non-fiber ISPs as well as for video streaming services and apps. For this study, ACSI interviewed more than 22,000 customers at random between April 2022 and March 2023.
AT&T Fiber tops fiber ISPs — and the entire industry — with a score of 80. CenturyLink (Lumen) Fiber is next at 78, followed by Google Fiber (76). The smaller group of fiber ISPs and Verizon Fios both score 75. Frontier Fiber and Xfinity Fiber round out the fiber ISPs at 74 and 73, respectively.
AT&T is targeting a few cities across Arizona and Nevada with its Gigapower joint venture, in partnership with BlackRock. Whereas Lumen just upped multi-gig coverage in its Quantum Fiber markets and Google Fiber announced several forthcoming builds.
Among non-fiber ISPs, T-Mobile takes the top spot with a score of 73. AT&T Internet finishes second at 72, while ACSI newcomer Sparklight sits in third place at 71. Kinetic by Windstream is next at 70, just outperforming Xfinity (68).
Despite an impressive showing among fiber ISPs, Lumen sits near the bottom in the non-fiber group with a score of 62. Frontier Communications and Optimum round out the non-fiber ISPs at 61 and 58, respectively.
“Across the entire customer experience, fiber service shows a strong advantage — from data transfer speed and service reliability to touchpoints like call centers and websites,” says Forrest Morgeson, Assistant Professor of Marketing at Michigan State University and Director of Research Emeritus at the ACSI. “That said, with well over half of U.S. households lacking access to fiber internet, availability remains a sticking point. As such, non-fiber ISP services remain an attractive option for many customers and should not be overlooked by providers.”
…………………………………………………………………………………………………………………………………………………………………
Fiber sets the pace for in-home Wi-Fi quality:
ACSI also measures key aspects of the in-home Wi-Fi experience for both customers who use equipment from their ISP and those who use third-party equipment that they have purchased.
Fiber ISPs (79) outperform both non-fiber ISPs (73) and third-party equipment providers (70) for overall Wi-Fi quality. The former far exceeds the other two in every customer experience benchmark, including strong marks for the security of its Wi-Fi connection (81) and reliability in terms of avoiding loss of service (80).

Charter Communications selects Nokia AirScale to support 5G connectivity for Spectrum Mobile™ customers
Nokia will deliver its AirScale portfolio, including 5G Radio Access Network (RAN), to support Charter Communications’ 5G rollout in trial markets. It marks Nokia’s first win in the cablecos/MSO space for large-scale wireless 5G deployments. Charter will use Nokia’s 5G RAN solutions to deliver wireless 5G connectivity, faster speeds, and increased network capacity to Spectrum Mobile customers in its trial markets in the United States.
Up until now, cablecos have been MVNO rather than actually deploying their own wireless networks. All of the cable companies in the U.S. with mobile aspirations have had to partner with an existing mobile network operator – Verizon, AT&T or T-Mobile – to sell mobile services. And those MVNO partnerships are not cheap. For example, the financial analysts at Wells Fargo estimate that Charter and Comcast pay Verizon $12-$13 per month for each of their mobile customers.
Cable operators have spent more than $1 billion on Citizens Broadband Radio Service (CBRS) spectrum with the intention to build 5G networks to offload traffic from their leased mobile networks and to deliver the fastest wireless service. Using compact and lightweight small cell products, cable operators can more easily and cost-effectively provide 5G wireless connectivity by leveraging their existing DOCSIS infrastructure without having to build additional cell sites.
With 6 million customer lines as of Q1-2023, Charter’s Spectrum Mobile is the nation’s fastest growing mobile network provider. Charter offers its Spectrum Mobile service through an MVNO deal with Verizon but touts its ability to combine that with its Wi-Fi network. It’s also using Citizens Broadband Radio Service (CBRS) spectrum to offload mobile traffic from the leased network. Charter spent more than $464 million in the CBRS auction in 2020.
As Charter continues to grow its mobile customers, the company needed a 5G wireless connectivity solution to offload traffic from its leased mobile network. Charter will deploy Nokia’s 5G RAN products, including strand mounted radios for CBRS, baseband units, and a newly developed 5G CBRS Strand Mount Small Cells All-in-One portfolio on the company’s assets, which will help Charter continue to deliver mobile traffic in strategic locations across its 41-state footprint while providing customers with the best possible 5G service experience.
Justin Colwell, EVP, Connectivity Technology at Charter Communications, said: “Charter is committed to providing our customers a fully converged connectivity experience that combines high value plans with the fastest wired and wireless speeds throughout our footprint. Incorporating Nokia’s innovative 5G technology into our advanced wireless converged network will help us ensure that Spectrum customers in areas with a high concentration of mobile traffic continue to receive superior mobile connectivity, including the nation’s fastest wireless speeds.”
Shaun McCarthy, President of North America Sales at Nokia, said: “This news builds on our more than 20-year relationship working with Charter to enhance its network. We are excited to expand its current trial to additional select metropolitan markets in the US, enabling an enhanced user experience for Spectrum Mobile subscribers. This win strengthens Nokia’s leadership position in the MSO space for 5G wireless deployments.”
Nokia in the U.S.
Nokia is supplying 5G technologies across its portfolio to the major service providers and leading operators, as well as hyperscalers, enterprises, and government organizations in the US. The company has an unrivaled track record of innovation in the U.S. including Nokia Bell Labs, which pioneered many of the fundamental technologies that are being used to develop 5G and broadband standards. Today, more than 90 percent of the U.S. population is connected by Nokia network solutions.
*Based on year end 2022 subscriber data among top 3 cellular carriers.
………………………………………………………………………………………………………………………………………………………
Nokia may have competition in the CBRS/MSO space. Samsung will be introducing a new solution within its already existing CBRS portfolio: a new 5G CBRS Strand Small Cell. Designed to be easily deployed on the MSOs aerial strand assets, it enables use of their existing infrastructure, helping them save on deployment costs.

Counterpoint Research: eSIM adoption now entering high-growth phase; +11% YoY in 2022
More than 6 billion xSIM (eSIM + iSIM) capable devices will be cumulatively shipped over the next five years, covering all form factors including hardware-based eSIM (eUICC), iSIM (iUICC), nuSIM and Soft SIM, according to Counterpoint’s latest eSIM Devices Market Outlook report.
Editor’s Note: An embedded SIM card – or eSIM – is pre-installed in a device and cannot be physically swapped. Instead, it is programmed remotely and can hold several SIMs at the same time. An integrated SIM (iSIM), meanwhile, is integrated in a device’s main processor, doing away with any form of dedicated hardware.
eSIM adoption has passed the inflection point and is now entering a high-growth phase, driven by the rising adoption of eSIM in smartphones, connected vehicles and cellular IoT applications. The next phase of growth will be driven by greater awareness of eSIM among mobile network operators (MNOs) and device manufacturers, facilitated by the flexibility, cost efficiency, security, cost savings and above all, the key role eSIM is playing in the digital transformation of MNOs.
In 2022, eSIM-capable device shipments grew 11% YoY to reach 424 million units despite a 3% YoY fall in overall cellular-connected device shipments due to weaker demand for smartphones. Globally, more than 275 MNOs support eSIM and provide connections to 30+ different eSIM-capable consumer device models on average. Furthermore, the number of cellular IoT modules and devices is continuously growing.
By 2030, 70% of all cellular devices are expected to support eSIM technology. Adoption will reach 100% in the smartwatch and drone segments; 92% for connected cars; 82% for smartphones; and 79% for tablets. Around 40% of eSIM devices will be smartphones, while 55% of eSIM devices shipped between 2021 and 2030 will be consumer devices.
Commenting on the outlook for xSIM-capable device shipments, Research Vice President Neil Shah said, “The physical MFF2/WLCSP form-factor soldered eSIM chip has been the go-to standard for eSIM implementation alongside the other niche alternative implementations such as soft SIM and nuSIM. Over the next five years, hardware-based eSIM (eUICC) will remain the dominant eSIM form factor and will account for more than half of all shipments.”
“The first wave of mainstream iSIM adoption will be seen across IoT applications driven by leading IoT chipset and module players such as Quectel, Telit, Sequans and Sony Semi (Altair) in partnership with leading xUICC players like Kigen, G+D and Thales. Other key stakeholders driving the adoption of iSIMs would include Qualcomm, IDEMIA, Truphone, Redtea Mobile, Oasis SmartSIM, Apple, Samsung and Nokia. Beyond 2028, iSIM is projected to take over as the dominant SIM form factor, with the shipments of iSIM-capable devices poised to climb to a cumulative 4 billion units by 2030.”
eSIM Has Reached an Inflection Point, Set to Enter a Period of Hyper-Growth
Source: Global eSIM Landscape – Market Outlook and Forecast
Commenting on eSIM adoption across different device categories, Senior Analyst Ankit Malhotra said, “Smartphones have been key in driving primary eSIM awareness among consumers and MNOs, and will continue to be the dominant eSIM-capable device category. Cellular connectivity in smartwatches is growing steadily which is also helping increase the penetration of eSIM-supported smartwatches. The adoption of entitlement servers by MNOs worldwide is a testament to the growing number of smartwatches and other companion devices powered by eSIM. Other cellular-capable consumer devices such as laptops and tablets will also see rapid eSIM adoption in the coming years.”
“The number of IoT/M2M devices equipped with eSIM is poised to grow faster than consumer device categories due to the natural cost, space and remote device management benefits that eSIM offers. The new eSIM IoT specifications SGP.31 by GSMA will accelerate eSIM adoption in the IoT segments potentially eradicating complexities of the existing eSIM Remote Service Provisioning (RSP) platform SM-DP/SM-SR for M2M/IoT segments.”
eSIM Devices Forecast and Analysis
Emerging device categories such as XR, drones and cellular gateways/FWA CPEs will be the fastest-growing categories. 5G-connected drones are another category that will benefit from eSIM technology and drive adoption across several use cases like last-mile delivery, disaster management, search and rescue, education, construction and agriculture. Regulation of beyond-visual-range drones in regions such as Europe will increase the adoption of eSIMs as well.
Automotive and smart mobility are huge growth areas as well. Connected cars are one of the largest and most obvious use cases for eSIMs. Consistent connectivity experience for mobility applications is becoming paramount, particularly for safety use cases such as eCall and the future rise of autonomous driving.
………………………………………………………………………………………………………………………………………………………………………………..
According to Omdia (owned by Informa), there is a compelling business case (subscription required) for eSIMs in the IoT market as they could help resolve connectivity issues plaguing enterprises. Some of the areas that could benefit include energy, healthcare and the financial sector, Omdia says.
Counterpoint forecasts iSIM will become the predominant type of SIM post-2028, with cumulative device shipments to reach 4 billion by 2030. Initial demand will come mainly from IoT applications, it says.
According to Omdia, the iSIM can alleviate issues such as chip shortages, energy and size constraints and increased security concerns. It also notes that cellular service providers such as AT&T, Vodafone and Deutsche Telekom have shown more enthusiasm for iSIMs than eSIMs.

Orange Launches 5G+ Network With Reduced Energy Consumption in Spain
Reuters: Majority of EU countries against network fee levy on Big Tech firms but 10 countries for it
Europe’s major telecommunications operators faced resistance from a majority of EU countries in their efforts to compel Big Tech companies to contribute to the funding of 5G and broadband deployment across the region, Reuters reported on Friday. At a meeting with EU industry chief Thierry Breton in Luxembourg on Thursday, telecoms ministers from 18 European countries either rejected the proposed network fee levy on tech firms, or demanded a study into the need and impact of such a measure, the sources said. That echoed comments made last month by EU telecoms regulators’ group BEREC.
European network operators including Deutsche Telekom, Orange, Telefonica and Telecom Italia want Big Tech to shoulder part of the network costs on the grounds that their data and content makes up a large part of network traffic. They have found a receptive ear in the European Commission’s industry chief Breton, a former chief executive of France Telecom and French IT consulting firm Atos.
Alphabet Inc’s Google, Apple Inc, Facebook parent Meta Platforms Inc, Netflix Inc, Amazon.com Inc and Microsoft Corp have rejected the idea of a levy, saying they already invest in the digital ecosystem.

The European telecom ministers cited the lack of an analysis on the effects of a network levy, the absence of an investment shortfall, and the risk of Big Tech passing on the extra cost to consumers, the people said. They also warned about the potential violation of EU “net neutrality” rules, which require all users to be treated equally, as well as possible barriers to innovation, and a lower quality of products.
- Critics of a network levy included Austria, Belgium, Czech Republic, Denmark, Finland, Germany, Ireland, Lithuania, Malta and the Netherlands, the people said.
- On the other hand, France, Greece, Hungary, Italy, Spain and Cyprus were among 10 countries which backed the idea, one of the people said.
- Poland, Portugal and Romania either took a neutral stance or had not adopted a position, the people said, but another person said they favoured a network fee.
Breton is expected to issue a report by the end of June with a summary of feedback provided by Big Tech, telecoms providers and others, which will help decide his next steps. Any legislative proposal needs to be negotiated with EU countries and EU lawmakers before it can become law.

Amazon NOT at all likely to offer mobile service to Prime Members or anyone else!
Wireless telecom stocks were down -5% to -9% at Friday morning’s open (they closed on June 2nd -4% to -6.25% lower). That horrendous performance was due to a Bloomberg article which claimed that “Amazon has been talking with wireless carriers about offering low-cost or possibly free nationwide mobile phone service to Prime subscribers, according to people familiar with the situation….It would let it offer Prime members wireless plans for $10 a month or possibly for free and bolster loyalty among its biggest spending customers, the people said, who requested anonymity to discuss a private matter.” About 167 million Amazon shoppers had Prime memberships as of March, unchanged from a year earlier, according to Consumer Intelligence Research Partners.
The Bloomberg article made this controversial statement, subsequently denied:
“The talks have been going on for six to eight weeks and have also included AT&T Inc. at times, but the plan may take several more months to launch and could be scrapped, an Amazon person said.”

Nothing could be further from the truth!
Amazon, T-Mobile US, AT&T and Verizon Communications all denied on Friday that anything is happening. T-Mobile’s statement on the matter strongly states that “Amazon has told us they have no plans to add wireless service.”
That echoes Amazon’s own statement which said “We are always exploring adding even more benefits for Prime members, but don’t have plans to add wireless at this time,” said Bradley Mattinger, an Amazon spokesperson.
“AT&T is not in discussions with Amazon to resell wireless services,” a company spokesperson said. A Verizon spokesperson told TechCrunch, “Verizon is not in negotiations with Amazon regarding the resale of the nation’s best and most reliable wireless network. Our company is always open to new and potential opportunities, but we have nothing to report at this time.”
T-Mobile told Barron’sthat “Amazon is a great partner to T-Mobile in many areas, and we are always interested in working more closely with our cross-town neighbors in new ways. However, we are not in discussions about inclusion of our wireless in Prime service, and Amazon has told us they have no plans to add wireless service.”
Wall Street analysts are skeptical that there is anything actually going on. MoffettNathanson analysts Craig Moffett and Michael Morton wrote in a research note published late Friday that any deal for Amazon to start its own phone service seems highly unlikely. (Moffett covers telecom and Morton covers internet stocks.) Moffett and Morton note that while Amazon could make it happen, the cost to the company of providing even a single line would be about $240 a year—above the annual cost of an Amazon Prime membership, currently at $139. And that’s just for one line—the costs would multiply with bigger families.
Another issue, they add, is that Amazon would suddenly be subject to regulation from the FCC. They point out that customer information is more tightly regulated in telecom than in related industries. That adds more risk to Amazon’s existing regulatory worries. “Even a minimal risk like this would be a deal breaker, in our view,” they write.
From a telecom perspective, the analysts also pour cold water on any potential deal. As for Dish Network , Moffett and Morton write, “there is virtually no chance…that Amazon would allow itself to play guinea pig on a start-up Dish wireless network.” Dish did not respond to a request for comment about the report.
In an interview with Barron’s, Moffett noted that Dish only has partial coverage— the company has launched service in 120 cities so far, but not in places like New York, Chicago, Los Angeles, Washington, or San Francisco. To cover the parts of the country it can’t reach, Dish has reseller agreements with both AT&T and T-Mobile. Moffett says that T-Mobile likely’s agreement with Dish doesn’t allow it to resell access to a third party—like Amazon. And AT&T’s agreement has similar language.
“Without the ability to resell AT&T or T-Mobile service, Dish simply isn’t a credible partner,” Moffett and Morton write. “Not only is their coverage insufficient to be a viable offering, but they’ve never operated a wireless network before, let alone a large-scale MVNO. [An MVNO is a carrier that has no network but instead resells service from other carriers.]”
With T-Mobile and Verizon having denied discussions, and Dish seeming very unlikely, that leaves only AT&T. And Moffett and Morton see little chance of that happening. “AT&T is smart enough to understand what an awful idea it would be to let Amazon into the hen house, in our view,” they wrote.
The two analysts also contend that a Prime Wireless plan wouldn’t do much to help Amazon grow its subscription business. They point out that Prime already has signed up about 80% of U.S. households and that churn rates for Prime are already “extremely low.”
Moffett and Morton conclude: “We’re skeptical that the incumbents would be willing to ink a deal with Amazon. We’re skeptical that Amazon would really want to. We’re skeptical that Amazon would be willing to do business with Dish Network. We’re skeptical about…well, all of it.”
Note also that Amazon failed dismally in 2014 with its Fire Phone, which was an attempt to compete with smart phones from Apple Inc. and Samsung Electronics Co., but it was killed a year later. MVNO brands including ESPN Mobile and Virgin Mobile both failed. Alphabet Inc. has the Google Fi service that runs on T-Mobile’s network and has only 2 million customers.
Let’s end with a question: One must consider if Bloomberg can be trusted as a reputable news source after their early morning June 2nd story?

Coherent Optics: Synergistic for telecom, Data Center Interconnect (DCI) and inter-satellite Networks
by Kalar Rajendiran, Alphawave Semi (edited by Alan J Weissberger)
The telecommunications industry has experienced significant growth in recent years, driven by the increasing demand for high-speed internet and data services. This growth has created a surge in traffic on optical networks, leading to the development of new telecom network architectures that can support the increasing demand for bandwidth.
Optical networking technologies, such as coherent optics, have traditionally been developed for telecom applications. However, with the growth of hyperscale data centers and the increasing demand for high-speed networking, these technologies are now also being adopted in data center applications. Traditionally, data centers have used copper or short-range optical cables to connect servers and storage devices within the same data center. However, as data volumes continue to grow and data center interconnect (DCI) requirements increase, coherent optical networking is becoming an attractive option for data centers. With coherent optical networking, data centers can achieve higher data transmission rates over longer distances, resulting in increased data capacity and lower latency. 400G was the first data rate where hyperscale data center applications outpaced telecom applications in the use of coherent optics.
Coherent optics enables the transmission of high-speed data over long distances by using advanced signal processing techniques to mitigate the effects of signal distortion and noise. This technology is essential for supporting the growing demand for high-speed internet and data services, particularly in areas where traditional copper-based networks are not feasible. This trend is likely to continue and proliferate further going forward, driven by the ongoing growth of cloud computing, big data, AI/ML workloads and other data-intensive applications.
Another driver of the shift towards optical interconnects has been the increasing complexity of satellite networks. As satellite networks become more complex, the need for high-speed, low-latency communication between satellites becomes more important. Optical interconnects are ideal for this type of communication, as they offer very low latency and can support high-speed data transfer between satellites.
Optical telecom synergies have played a significant role in the evolution of inter-satellite communication. Many of the technologies and techniques used in optical telecom networks have been adapted for use in inter-satellite communication. Innovations in optical digital signal processing (DSP) and system automation also offer several optimization opportunities with inter-satellite interconnects. Benefits include:
- Improved Signal Quality: Optical DSP can be used to compensate for impairments in the optical signal, such as chromatic dispersion and polarization mode dispersion. This can improve the quality of the signal and reduce the bit error rate (BER), enabling high-quality communications over long distances.
- Reduced Latency: System automation can also be used to optimize the routing of data between satellites, minimizing the number of hops and reducing latency. This can improve the responsiveness of the system and enhance the user experience.
- Power-efficient Modulation Formats: Optical DSP can enable the use of power-efficient modulation formats, such as pulse-amplitude modulation (PAM), which can reduce the power consumption of the inter-satellite links while maintaining high data rates.
- Energy-efficient Signal Processing: Optical DSP can also be optimized to perform signal processing operations more energy-efficiently. For example, parallel processing and low-power digital signal processing techniques can reduce the power consumption of the signal processing circuitry.
At the recent Optical Fiber Communication (OFC) conference, Alphawave Semi (located in London, UK) showcased its ZeusCORE XLR test chip during the interoperability demonstration organized by the Optical Internetworking Forum (OIF). Alphawave Semi executives Loukas Paraschis, VP of Business Development and Tony Chan Carusone, CTO, presented on high-speed connectivity leadership. Their presentations touched on the growing synergies and optimization opportunities of inter-satellite interconnects and optical telecom through innovations in optical DSP and system automation.
As the volume of data traffic on optical networks continues to increase, it is essential to ensure that the cost of implementing and maintaining these networks remains affordable. This requires a delicate balance between increasing volume and decreasing costs, which can only be achieved through innovation and the development of highly-integrated co-designed solutions. These solutions combine multiple technologies and functions into a single device, reducing the complexity and cost of optical network infrastructure. This approach enables the development of more efficient, cost-effective optical networks that can meet the growing demand for bandwidth and high-speed data transmission.

Ericsson and MediaTek set new 5G uplink speed record using Uplink Carrier Aggregation
Ericsson and MediaTek have set a new 5G uplink speed record of 440 Mbps in low-band and mid-band spectrum using Uplink Carrier Aggregation. That uplink speed was achieved in an Ericsson lab. The test was performed with Ericsson’s Radio Access Network (RAN) Compute Baseband 6648 and a mobile device using a MediaTek Dimensity 9200 flagship 5G smartphone chipset.
More precisely, the combination used was 50MHz FDD n1 and 100MHz TDD n77. By aggregating these two bands, communications service providers can considerably increase their uplink speeds, resulting in better network performance and user experience. The fast uplink speed brings better, smoother experiences for the likes of video conference users, streamers, and their audience with more frames per second and higher image resolution. The 440 Mbps 5G upload speed achieved in the lab compares to an average of 26.78 Mbps outdoors and 22.98 Mbps indoors, as per a Cellsmart survey.
Sibel Tombaz, Head of Product Line 5G RAN, Ericsson, said: ”Super-fast uplink speeds make a big difference in the user experience. From lag-free live streaming, video conferencing and AR/VR apps, to more immersive gaming and extended reality (XR) technologies. The 440 Mbps upload speed achieved by Ericsson and MediaTek will help make that difference. We are also continuously designing innovative solutions for optimizing 5G networks so our customers can make the best use of their spectrum assets.”
Service providers are seeking innovative ways of boosting capacity while using existing spectrum efficiently to meet growing demands for wireless data and applications. This is where carrier aggregation comes in, optimizing the service provider’s spectrum assets to bring to users better coverage, increased capacity, and higher data speeds.
HC Hwang, General Manager of Wireless Communication System and Partnership at MediaTek, said: “The successful result of combining Ericsson’s state-of-the-art 5G Baseband and MediaTek’s flagship smartphone chip has achieved another 5G industry milestone, and paves the way for superior mobile experiences to benefit users every day.” Uplink speed is becoming more crucial with the expected uptake of
gaming, XR, and video-based apps. For example, as AR devices gain popularity with larger augmentation objects, rendering becomes more demanding. This increases the demand on networks to deliver higher throughput and lower latency.

Earlier this year, AT&T boasted that it had completed what was believed to be the first 5G standalone (SA) uplink 2-carrier aggregation data connection in the U.S.
The connection was made at its Redmond, Washington, lab, where they achieved upload speeds of over 120 Mbps with a combination of 850 MHz and 3.7 GHz spectrum.
In May, T-Mobile reported reaching uplink speeds over 200 Mbps in a 5G data call using uplink CA; in that case, they used T-Mobile’s live commercial 5G SA network as opposed to a lab environment. T-Mobile used 2.5 GHz and 1.9 GHz bands.

Cellsmart: 5G download performance improves but upload performance lags
UK market research firm Cellsmart finds that 5G network performance has greatly improved over the last 12 months. Real-world testing shows new peak download and upload speeds on 5G
networks. The industry is on the cusp of the gigabit era in cellular networks with these speeds moving from the lab to field in 2023.
Cellsmart survey results revealed the global average outdoor download speed for 5G is 210.05 Mbps, compared to 182.46 Mbps indoors. 5G download speeds show a significant improvement over 4G with an increase of 486.57% (outdoor) and 694% (indoor).
Average upload speeds continue to lag behind download speeds with almost no improvement from 4G to 5G in indoor tests. Both 4G and 5G upload speeds remain significantly lower than download speeds. 5G upload speeds as a percentage of download speeds is 17%, compared to 74% on 4G. Download and upload speeds remain hyper-asymmetrical in 5G, which needs to improve to support enterprise use cases.

The survey results also revealed how latency is negatively impacted in indoor settings, with average 5G latency being 14.58ms lower indoors than outdoors. Tests run in Norway and the Philippines had outdoor speed tests that showed latency of less than 10ms, followed closely by US (10ms), China (11ms) and France (11ms). Average latency indoors was 15.32 higher on 4G than outdoors.
At the city level, Norway’s Oslo leads the way, while Spain’s Cerdanyola del Vallès and Bilbao come in second and third, while fourth placed Munich also recorded a 5G download speed in excess of 1 Gbps.
“Europe is ready for fixed wireless access,” declared Toby Forman, CEO at SmartCIC, owner of Cellsmart.
“Our test results show that 5G is beginning to mature into a justifiable investment that is ready to serve as an alternative to wired broadband and LEOs in multiple countries throughout Europe,” Forman said. “With performance rates that rival those of broadband and LEO, cellular should be considered when connecting enterprise locations. It’s a viable option.”
Cellsmart earlier this month reported that 5G upload speeds are insufficient for industrial applications.
As Cellsmart’s mission is, in its own words, “liberating enterprise from the constraints of fixed line connectivity,” it clearly has a vested interest in the results of its own study. It helps enterprises hook up to Fixed Wireless Access (FWA) solutions, essentially. However, the data still makes interesting reading against a backdrop of mobile network operators spending billions on the rollout of 5G networks.
