There are a handful of significant trends that will emerge over the next several months as service providers navigate their transformation and seek to find their Competitive EDGE. This post will focus on the increasing shift to multi-gigabit services, the growing importance of the network edge and how service providers are being transformed into “experience providers..
Multi-Gigabit Broadband Services are Becoming the New Standard – The shift to gigabit services was both widespread and well suited for Gigabit Passive Optical Networking (GPON) However, new advanced applications will require symmetrical multi-gigabit speeds. The proliferation of multiple devices using these bandwidth-hungry apps is pushing service providers to begin to think 10 gig services and beyond for both business and residential services. The emergence of the metaverse, with Ultra High Definition (UHD) Augmented Reality/Virtual Reality/Extended Reality (AR/VR/XR) and gaming applications will continue push these boundaries.
The Network Edge Continues to Rise as a Strategic Location – The rise of 10 Gigabit Symmetrical (XGS)-PON and multi-gigabit services that support the above mentioned applications and more is creating new challenges in the network – especially as these apps require symmetrical bandwidth. Service providers realize that they must push equipment as close to the subscriber as possible to optimize traffic management, but also to minimize latency, which is becoming increasingly important in the world of the metaverse and AR/VR/XR apps. Additionally, leveraging intelligence at the edge moves it closer to where data is actually created and consumed and where the subscriber experience is defined giving service providers increased agility in monitoring, managing and optimizing performance.
Service Providers are Rapidly Transforming into Experience Providers – As the network becomes increasingly software defined and intelligent equipment is deployed closer to the edge, the ability for carriers to both gather meaningful information that can reflect and provide actionable insights into user experience grows dramatically. As a result, the concept of a true “experience provider” is emerging where subscriber problems can be anticipated and proactively addressed, and user needs can be addressed remotely and immediately in an extraordinarily personalized manner. This transformation is proving to have profound impacts on carrier performance, with dramatically reduced churn, faster responsiveness, better performance, and higher Average Revenue Per User (ARPU).

“It’s Not Just You: 5G Is a Big Letdown,” is the title of a Wall Street Journal on-line article published today (January 11, 2023). Author Joanna Stern writes:
I turned off Verizon’s red down pointing triangle 5G on my iPhone—and barely noticed a difference. The 4G LTE performance and coverage felt just about the same.
Three years since the U.S. cellular carriers lit up their next-generation networks and promised to change the game, the game hasn’t changed. And if you’re among the millions of Americans who recently upgraded, you probably already know that. In 2022, 61% of U.S. cellular customers accessed 5G networks, according to Global Wireless Solutions, a network testing and research company.
On Verizon’s Ultra Wideband network, I got 500 Mbps down. But I didn’t notice a difference when streaming Netflix, watching TikTok, loading websites or sending messages. You don’t need a fire hose to extinguish a candle.
Where you might see a difference is during commuting hours and other times of heavy congestion, Chetan Sharma, a telecom-industry analyst, told me. A Verizon spokesman said that 5G’s higher data capacity helps at concerts, sporting events and other crowded areas where everyone is trying to download or upload photos or videos.
“As cars, smart home standards, and so many screens took center stage at this year’s [CES] show, 5G took a back seat,” concludes a Verge article titled, “Where was 5G at CES?” “After years of hype, 5G was seemingly a no-show at CES 2023.” The Verge article continues knocking 5G (and for good reason):
For starters, we’re all sick of hearing about it. And CES has a unique way of rallying around a technology one year and then leaving it for dead the next.
And there was always a time limit on 5G’s newsworthiness — at a certain point, when it becomes the prevailing wireless technology, it’s not going to be “5G the new thing;” it’ll just be “the internet you use when you’re not on Wi-Fi.”
More than any of the above, the time has passed where wireless CEOs feel they need to sell 5G to the general public (and, of course, their shareholders). It’s not a niche new service anymore; it’s the default option (in the U.S. at least). Basically every new phone sold on their shelves is 5G compatible, and mid-band 5G finally exists on all major carriers in large parts of the US. The next time you walk into a wireless store to buy a new phone or sign up for a new service, you’ll have a very hard time leaving without a 5G device and plan, regardless of whether you really wanted them.
So now we have 5G phones in our hands, 5G networks are here, and… not much has changed. Maybe web pages load a little faster — hardly robot surgery. What gives? The thing is, rolling out 5G is a long ongoing process. The hype made it seem like all the good stuff was just around the corner, but truthfully, it was (and still is) years and years away.
So yes, you may have a 5G icon on your phone, but the most transformative aspects of 5G are supposedly still in the works. That’s a tough message to sell in a flashy keynote, especially when everyone in the room has access to the technology you’re talking about.
The IEEE Techblog in general, and this author in particular, have been pounding the table for years that 5G would be a colossal tech train wreck for these reasons:
1. 3GPP Release 16 URLLC in the RAN spec and performance testing have not been completed. Hence the URLLC in 3GPP Release 15 and ITU M.2150 recommendation do not meet the critically important URLLC ITU M.2410 performance requirements for ultra high reliability or ultra low latency. Here is the latest status of URLLC in the RAN in the 3GPP Release 16 specification as of 6 January 2023:
–Physical Layer Enhancements for NR Ultra-Reliable and Low Latency Communication (URLLC) NR_L1enh_URLLC 1 Rel-16 R1 6/15/2018 12/22/2022 96% complete RP-19158
–UE Conformance Test Aspects – Physical Layer Enhancements for NR URLLC NR_L1enh_URLLC-UEConTest 2 Rel-16 R5 12/14/2020 12/22/2022 90% complete RP-202566 RP-221485
2. There is no implementation standard for 5G SA Core network– only 3GPP reference architecture specs which list alternative implementation schemes, most of which are “cloud native.” That resulted in a lot of telco confusion that delayed the roll out of 5G SA networks such that most 5G deployed today is NSA which uses 4G LTE core network and functions. Dell’Oro Group’s Dave Bolan wrote in a white paper:
The 5G Core is the key to monetizing the 5G SA network bringing MNOs (Mobile Network Operators) into the modern cloud era, allowing the MNO to (1) offer new services quickly with Cloud-Native Network Functions, (2) add Network Slices on demand for mobile private networks, and (3) address latency-sensitive applications with MEC. These new opportunities cannot be addressed by 4G or 5G NSA networks, and the sooner an MNO embraces 5G SA networking, the closer it will be to reaping new revenue streams.
3. ALL of the 3GPP defined 5G functions and features, require 5G SA Core network. Those 5G functions include 5G security, network slicing, and automation/virtualization. MEC also needs a 5G SA Core network to work efficiently with a 5G RAN. There are relatively few 5G SA Core networks deployed and for those that are, there are few of the highly touted 5G functions available, e.g. T-Mobile is a case in point.
4. There is no standard for roaming between 5G networks, especially not when there are different versions of 5G SA core networks- each requiring a different software download for 5G endpoint devices. Hence, 5G is not truly mobile in the sense of portability. 5G is probably best used for FWA or local M2M/IoT communications where there are no roaming requirements.
5. There is no standard for 5G Frequency Arrangements (ITU M.1036 revision 6) which are critically important for all the mmWave frequencies specified at WRC 19 for 5G, but frequency arrangements not yet agreed upon by ITU-R WP 5D.
6. 5G base station and endpoint devicepower consumption is very high, especially for the mmWave frequencies which deliver the fastest 5G speeds.
The White House is working through the NTIA to develop a national spectrum strategy that would cover 5G, 6G and other spectrum users.
According to FierceWireless, National Telecommunications and Information Administration (NTIA) chief Alan Davidson said that work would continue throughout this year. Speaking at last week’s CES conference in Las Vegas, Davidson reminded the audience that the NTIA manages federal spectrum use and serves as the President’s advisor on spectrum policy. That means that the NTIA works together with the FCC to manage spectrum when a federal user is involved. From a practical perspective, the Department of Defense has historically held a lot of valuable spectrum for national security use, making the DoD an incumbent user in many spectrum bands.

In 2023 NTIA will be working with federal agency partners to develop a national spectrum strategy, which will provide a long-term plan to meet both commercial and federal spectrum needs.
Officials from the National Oceanic and Atmospheric Administration (NOAA) said they’re taking stock of the agency’s spectrum usage in order to potentially release some for commercial uses, according to SpaceNews. “It is an ongoing challenge. We expect to have to fight for maintenance of spectrum. But at the same time, we realize we’re not going to win every fight,” said Steve Volz, NOAA Satellite and Information Service assistant administrator on January 11th at the American Meteorological Society meeting.
Spectrum for 5G and 6G is a critical national policy topic:
“Continuing to meet increasing consumer demand and expectations, ensure continued growth of the US economy, bridge the digital divide, and facilitate global leadership on next-generation technologies requires sufficient spectrum resources,” wrote the CTIA, the US wireless industry’s main trade association. “Accordingly, it is imperative that the commission continually replenish its pipeline of spectrum allocated for commercial mobile and fixed broadband services.”
“America needs a national strategy to make sure there is enough spectrum to build out 5G networks and not fall behind China,” wrote Mike Rogers, a former Congressional representative from Michigan who authored a report critical of China’s Huawei, in The Hill.
Joel Thayer, of the Digital Progress Institute, agreed. “If we cannot get our act together and follow an all-of-the-above spectrum strategy, we cede the race to 5G and even 6G to China. Full stop,” he wrote in The Hill.
Such arguments strongly echo the “race to 5G” rhetoric that wasubiquitous in policy circles in the early days of 5G.
Cloud-native network functions (CNF) promise to change the dynamic of telecommunications network function engineering. The advent of 5G has added impetus to this change. Insight Research is at the cutting edge of CNF market analysis. Here are a few excerpts from our new report on the Virtualized Network Function Orchestrator (VNFO) market
Insight Research considers Virtual Machines (VMs) and Containers to be the major Virtual Network Function Orchestration (VNFO) methodologies. Network functions synthesized using VMs and Containers qualify as Virtual Network Functions (VNFs), in our opinion. That latter term has taken on much broader context since it was first introduced in the context of Network Function Virtualization (NFV) at the OpenFlow World Congress in 2012.
VNFs orchestrated by Containers are sometimes referred to as cloud-native NFs (CNFs). Insight Research has also employed this term as early as 2020. Over time however, we have observed that the usage of CNFs is neither consistent nor uniform.
Most ‘traditional’ Management and Orchestration (MANO) schemes such as ONAP, OSM and all proprietary offerings now support Containers and Kubernetes [1.]. Containers are thus one more mean towards achieving the end-objective of VNFs. As such, Insight Research finds it more appropriate to use VNF as an umbrella term and refer to VM or Container as the specific virtualization methodology.
Note 1. Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.
The question then arises – where would we slot network functions (NFs) orchestrated by containers encapsulated in VMs? Answer is containers. Similarly, NFs orchestrated by VMs encapsulated in containers are slotted under VMs.
The table below breaks down the VNFO market by virtualization methodology.
We see Containers gaining major market share from VMs such that they are running away with the VNFO market. The advantages of containers over VMs are all well known. Containers are sleeker and when employed with optimal microservice granularity – considerably faster as well.
Additionally, VMs have a head start over containers and have established a solid legacy which will hold good for near to midterm future. However, barriers surrounding container adoption are gradually dissolving with differing momentums across end-applications. The greater the performance differential, the greater is the adoption potential for Containers in end-applications.
Initiatives such Nephio have placed Kubernetes in the center of the VNFO universe. In short, it’s a matter of time before Containers push VMs to be the dominant VNFO virtualization vehicle. However, many question arise.
Here are a few questions for starters:
Is the NFVO the same as service orchestrator?
Is the NFVO the same as SDN controller?
Is Kubernetes an orchestrator?
Since containers and VMs can be embedded inside one another, how do we stamp which virtualization methodology they are using?
If a proprietary MANO uses portions of open source code, should it be considered proprietary?
After picking the brains of numerous experts who were unfailingly patient in unravelling their thinking, Insight Research has been able to arrive at a set of clearcut definitions and assumptions that address the above queries and more.

IPv6 is the first and might be the last upgrade of the global network in the coming decades. The development of IPv6 and IPv6 derivative and convergence technology standards will meet the objective requirements of the continuous expansion of the future network, facilitate the digital transformation in multiple fields, and become a new track of global digital technology innovation. In light of this, the “Global IPv6 Development and Standard Evolution Symposium and the Release Ceremony of the 2022 IPv6 Support White Paper,” held by the IPv6 Forum and the China Future Internet Engineering Center (CFIEC) on January 5, 2023.
The event accumulates global experts from global organizations from IPv6 Forum, CFIEC, Asia-Pacific Internet Network Information Center (APNIC), China Academy of Information and Communications Technology (CAICT), Internet Engineering Task Force (IETF), China Communication Standardization Association (CCSA), Institute of Electrical and Electronics Engineers (IEEE), European Telecommunications Standardization Association IPv6 Enhanced Innovation Working Group (ETSI IPE). Experts discuss the development vitality and opportunities of IPv6 under the new turning point of digital economy, strengthen the in-depth cooperation between different organizations, establish a perfect IPv6 and derived and fusion technology standards. accelerating large-scale deployment of IPv6 globally in the “global IPv6 development” and “IPv6 standard evolution” dimensions.
IPv6 is leading the development of the Internet
IPv6 provides more innovation capacity and development space for network infrastructure. Wu Hequan, academician of the CAE Member, summarizes the current development trend and characteristics of IPv6 at the meeting. He believes that the global Internet development has entered the dominant period of IPv6, which mainly presents three characteristics: first, the transition from IPv4 to IPv6 is accelerating; Second, from IPv4/IPv6 dual stack to IPv6 only; Third, IPv6 is developing towards IPv6+, with the developing IPv6 address space capabilities and fully integrating with the new generation of IT. IPv6 is playing an active role.
Liu Dong, Vice President of IPv6 Forum, introduced the development of the global IPv6 deployment in general: “The global IPv6 deployment speeds up to a new level in 2022. Countries or regions with a combined IPv6 deployment rate of around 30% or above account for more than half of the world. IPv6 deployment rate in 26 countries exceeded 40%, an increase of 9% compared with 2021; 37 countries have deployment rates exceeding 30%; The deployment rate of 51 countries exceeded 20%. IPv6-only has become a global consensus. The IPv6 applications and users will grow rapidly in the future ”
Sharing the development of IPv6 deployment in the Asia-Pacific region at the conference, Pan Guangliang, Director of Basic Resource Services at the Asia Pacific Internet Network Information Center (APNIC), puts, “The growth of the Internet has not stopped and will not stop. As more and more devices connects to the Internet, IPv6 is the way to go and is growing globally, with Asia seeing strong growth in overall IPv6 capability. According to APNIC statistics, the IPv6 support capacity in Asia exceeds the global average level by nearly 40%. Several countries such as China, India and Malaysia have witnessed rapid IPv6 development. In the next few years, the deployment of IPv6 will continue to improve, and more innovative applications based on IPv6 will appear ”
The development of IPv6 in China is outstanding. Gao Wei, director of the Internet Center of the Standards Institute of the China Academy of Information and Communications Technology, points out at the conference: “China is among the first countries in the world to carry out research, standard setting, application development and large-scale commercialization of IPv6 and next-generation Internet technologies. By December 2022, the number of IPv6 users in China has reached 717.7 million, with IPv6 traffic on fixed networks accounting for 12% and mobile networks 46%, showing a good momentum of development. IPv6 transformation achieves monumental success especially in the cloud platform, to achieve the new era of IPv6 traffic increase to provide strong support.”
IPv6 standard evolves from IPv6-Only to “cloud network”, “computing network” and “security”
In the era of digital economy, the integration of the Internet and the economy continues to deepen, and industrial digitalization with digital industrialization have become opportunities for all industries to score a new chapter. As an important starting point of digital transformation, standard is more conducive to opening up a leading advantage in the changing situation. The research, development and creation of IPv6 and its derived and converged technical standards are closely related to the development and deployment of IPv6. With the accelerated deployment of IPv6, the international standardization of IPv6 has entered a new stage and came across new changes.
Zhao Huiling, chairman of CCSA TC3 Technical Committee of China Communications Standardization Association, says that after 20 years of development, the current IPv6 standards have formed a systematic and standardized trend, covering five categories of standards: resources, networks, applications, security and transition. The standards at this stage can meet the needs of IPv6 network construction, but the security standards and application standards still have a lot to catch up. She also proposes four key directions for the creation of IPv6 industry standards in the new stage:
First, in the field of cloud network integration, IPv6 supports the deep integration of new resources such as cloud network edge intelligent collaboration and data computing power;
Second, in the field of IOT, IPv6 supports seamless global coverage, and anyone can communicate with anyone at any place and any time.
Third, in the field of intelligent operation and maintenance, IPv6 supports end-to-end network quality assurance to ensure that the demands of the cloud on the network in enterprise production scenarios are met.
Fourth, in the field of security and credibility, IPv6 supports end-to-end security endogenous mechanisms, adaptive security frameworks and security atomic capabilities, security defense, detection, and response prediction.
Li Zhenbin, member of the IETF Internet Architecture Committee (IAB) and Huawei’s chief IP protocol expert, also mentions that, “As the data communication industry moves towards the intelligent connection era of IPv6+, IETF has also gradually carried out various IPv6 standardization work, including the IPv6+1.0 (SRv6) standard, the IPv6+2.0 (5G&Cloud) standard Important achievements have been made in relevant standards. At this stage, IPv6 provides more differentiated service capabilities. Cloud network and computing network become the key applications of IPv6. Through IPv6 expansion and APN and other technologies, personalized networks can be realized and diverse computing power requirements can be met. In terms of APN6, we have signed a standard manuscript with several operators to successfully promote BOF at IETF, which will be the key direction of future technology innovation and standard creation. In addition, the general tunnel encapsulation technology GIP6 based on IPv6 also deserves further attention. ”
After years of deployment and penetration, IPv6 has entered a golden age of IPv6-Only evolution. When introducing the development of IPv6 at ETSI, Xie Chongfeng, Vice Chairman of ISG at ETSI IPE (IPv6 Enhanced innovation) and senior expert on IPv6 at China Academy of Telecommunication Research, says that network infrastructure is multi-domain and multi-scenario. To this end, we should actively promote the multi-domainIPv6-Only network architecture and technical requirements, in the form of a standard in the industry consensus, which will help operators, OTT, and service and devices manufacturers to buildIPv6-Only networks, and promote network infrastructure towards IPv6-Only.
The Release of 2022 Global IPv6 Support White Paper:
This seminar is not only a rare multilateral interaction and exchange between domestic and foreign organizations and experts on IPv6 development and standards, but also a demonstration of the fruitful results achieved in promoting IPv6 globally in the past year. At the meeting, the 2022 Global IPv6 Support White Paper jointly prepared by the IPv6 Forum and CFIEC was officially released. Latif Ladid, the president of the IPv6 Forum, says at the release ceremony that the white paper is based on the latest progress of global IPv6 technology, the number of global users, the network and domain name system, international operators, websites, cloud services Network equipment and other parties elaborate on the global IPv6 support and make multi-dimensional and multi-dimensional statistics to comprehensively, objectively and accurately reflect the global IPv6 development. At the same time, the IPv6 Forum also selected “IPv6 Outstanding Contribution Enterprises” and “IPv6 Pioneer Enterprises” in 2022 based on the white paper. Latif Latid gives awards to five enterprises including Cisco, Huawei, HP, H3C and D-Link, with the “IPv6 Outstanding Contribution Enterprise” award, and ten enterprises, Dell, IBM, TOPSEC, QI-ANXIN, Allied Telesis, Panasonic, Microsoft, ZTE, China Mobile and TP Link, receive the “IPv6 Pioneer Enterprise” award. Yang Wu, chief architect of the H3C Router product line, Zhu Keyi, head of the Huawei Digital Communication Standards and Patent Department, and Han Minglei, an expert on TUPSEC protocol conversion products, also shared the latest IPv6 solutions and products at the meeting.
Liu Dong, Vice President of the IPv6 Forum and director of CFIEC, illustrates: “At the beginning of the year, it is a great pleasure to meet with you online. Through your sharing, we can see that we have made progress in two important dimensions, ‘Global IPv6 Development’ and ‘IPv6 Standard Evolution’, and formed a large number of new achievements. In the future, our various organizations will continue to deepen cooperation and make use of advantages. While moving towards IPv6-Only, the first is to maintain continuous innovation and improve the IPv6 network value; The second is to actively expand the innovative application of IPv6 in the context of the Internet of Everything. The third is to create and improve new technical standards for the sustainable development of IPv6. Let us accelerate the global IPv6 scale deployment, and let IPv6 and the Internet benefit everyone. ”
Scientists in China claim they have found a way for current-generation quantum computers to crack the RSA algorithm underlying the most common form of online encryption. The researchers said the encryption could be broken with a 372-quantum-bit (qubit) system using hybrid quantum-classical methods to overcome scaling limitations. The Chinese paper “Factoring integers with sublinear resources on a superconducting quantum processor” stated that the algorithm used factored a number with 48 bits on a quantum system with 10 qubits.
The likelihood that quantum computers would be able to crack online encryption was widely believed a danger that could lie a decade or more in the future. But the 24 researchers, from a number of China’s top universities and government-backed laboratories, said their research showed it could be possible using quantum technology that is already available. The quantum bits, or qubits, used in today’s machines are highly unstable and only hold their quantum states for extremely short periods, creating “noise.”
As a result, “errors accumulate in the computer and after around 100 operations there are so many errors the computation fails,” said Steve Brierley, chief executive of quantum software company Riverlane. That has led to a search for more stable qubits as well as error-correction techniques to overcome the “noise,” pushing back the date when quantum computers are likely to reach their full potential by many years. The Chinese claim, by contrast, appeared to be an endorsement of today’s “noisy” systems, while also prompting a flurry of concern in the cyber security world over a potentially imminent threat to online security.
Massachusetts Institute of Technology’s Peter Shor pointed out that the team had “failed to address how fast the algorithm will run,” as it could “still take millions of years.” Shor, the American mathematician who first proposed a way for quantum computers to crack encryption, predicted that the inability to run all the computations at once meant it would take “millions of years” for a quantum computer to run the calculation proposed in the paper. The Chinese research comes at a time when many companies working on the technology are in a race to prove that today’s “noisy” systems can reach so-called quantum advantage — the point at which a quantum computer can perform a useful task more efficiently than a traditional, or “classical”, machine, ushering in commercial use of the technology.
Brierley at Riverlane said it “can’t possibly work” because the Chinese researchers had assumed that a quantum computer would be able to simply run a vast number of computations simultaneously, rather than trying to gain an advantage through applying the system’s quantum properties.
Four years ago, John Preskill, a professor of theoretical physics at the California Institute of Technology, predicted that quantum systems would start to outperform and might have commercial uses once they reached 50-100 qubits in size. But that moment has come and gone without quantum systems showing any clear superiority. IBM unveiled a 127-qubit computer more than a year ago, and last month announced that a new 433-qubit processor would be available in the first quarter of 2023. These days, Preskill sounds more cautious. “I expect that for practical applications with significant business value we’ll have to wait for error-corrected fault-tolerant quantum computers,” he said, adding that this was likely to be “a ways off.” But he added that today’s systems already had scientific value. One reason that hopes have retreated is that new ways have been found to program classical computers to handle tasks that were once thought to be beyond them.
This has pushed back the quantum frontier, delaying the moment when people building quantum systems can claim an advantage, said Oskar Painter, head of quantum hardware in the cloud computing division at Amazon, one of the tech companies that is building its own quantum computer. “They never finally could say, ‘This will be better,’” he said. After years of rising expectations, the lack of practical uses for the technology has led some experts to warn of a potential “quantum winter” — a period when disappointment about a new technology leads to a waning of interest for a number of years. The term is borrowed from the AI “winters” of the 1970s and 1980s, when a number of promising research avenues turned out to be dead ends, setting the field back for prolonged periods.
“People are worried it will be really harsh,” said Painter at Amazon Web Services. Like many in the field, though, he said that any short-term backlash was unlikely to hit long-term research funding. “I don’t think it will go away.” Receding hopes for early benefits from quantum computing have already contributed to a sharp fall in the stocks of a handful of companies that rode the wave of enthusiasm over the sector to go public since the middle of 2021. Based on their peak share prices soon after they each went public, Arquit, IonQ, D-Wave and Rigetti reached a combined value of $12.5bn. That has since fallen to $1.4bn.
Among the events to batter the quantum companies last year, IonQ was hit by a report from a short seller claiming its technology did not live up to its claims, while Rigetti founder Chad Rigetti was removed as chief executive before quitting the company late in the year.
Part of the problem facing the sector has been an excess of “hype” about the technology, said Constantin Gonciulea, chief technology officer of advanced technology at Wells Fargo. He compared the build-up of expectations around quantum to the crypto industry, as many non-experts have been drawn into the field and promises for the technology have far outgrown its potential in the near term. Despite this, companies working on the first quantum machines and software still insist that practical uses of the technology are just around the corner — while continuing to carefully avoid giving too precise a prediction about exactly when that will be.
David Rivas, head of engineering and product at Rigetti, said that the company still believed it would reach quantum advantage when its computers have “a few hundred to a few thousand qubits.” Even if they cannot match the performance of today’s supercomputers, they will still be useful if they cost much less, or if they can operate faster or with more precision, he said. For some quantum companies, the startling Chinese claim about online encryption was a sign that the technology’s big moment is drawing nearer. But for the doubters, the apparent impracticality of the research will serve as confirmation that quantum computing is still an impressive science experiment rather than a practical technology.
The Federal Aviation Administration (FAA) is giving the aviation industry more time to update legacy radio altimeters that could potentially be impacted by terrestrial 5G operations in C-Band spectrum.
In a notice of proposed rulemaking (to be published January 11, 2023), the FAA said that it remains concerned about the impacts of the C-Band operations on flights, including triggering false warnings from flight systems—particularly as more 5G is deployed across the entire band, and with more than 20 additional operators expected to start operating in the band later this year. This new Notice of Proposed Rulemaking (NPRM) lays out a timeline for retrofits by February 2024.
SUMMARY: The FAA proposes to supersede Airworthiness Directive 2021-23-12, which applies to all transport and commuter category airplanes equipped with a radio (also known as radar) altimeter. AD 2021-23-12 requires revising the limitations section of the existing airplane/aircraft flight manual to incorporate limitations prohibiting certain operations requiring radio altimeter data when in the presence of 5G C-Band interference as identified by Notices to Air Missions.
Since the FAA issued AD 2021-23-12, the FAA determined that additional limitations are needed due to the continued deployment of new 5G C-Band base stations whose signals are expected to cover most of the contiguous United States at transmission frequencies between 3.7-3.98 GHz. This proposed AD would require revising the limitations section of the existing airplane/aircraft flight manual to incorporate limitations prohibiting certain operations requiring radio altimeter data, due to the presence of 5G C-Band interference.
This proposed AD would also require modifying certain airplanes to allow safe operations in the United States 5G CBand radio frequency environment. The FAA is issuing this AD to address the unsafe condition on these products.
Originally, the agency had targeted a phased approach that required operators of regional aircraft with the most susceptible altimeters to retrofit them with filters by the end of 2022. AT&T and Verizon, meanwhile, had agreed to delay 5G C-band deployments near airports until July 2023, at which time air carriers were expected to have completed all the retrofits to mitigate possible 5G C-band spectrum interference.
Concerns about the impacts of 5G in C-Band to radio altimeters delayed the initial deployment of C-Band spectrum by AT&T and Verizon roughly a year ago. The worry is that the old altimeters, even though they operate in a completely different spectrum range, were not designed to filter out strong terrestrial cellular signals, leading to out-of-band interference. That interference could lead to the radars not being able to accurately gauge an aircraft’s height-above-ground, which could lead to aircraft crashes—particularly in fog or other situations where pilots would not be able to visually confirm whether height information was correct. As a result, Verizon and AT&T voluntarily agreed to operational tweaks near certain airports, including 5G transmission at reduced power levels, or tilt adjustments to cell sites to direct energy away from protected areas.
The FAA said that it has been able to review data from “dozens of alternative method of compliance (AMOC) requests, demonstrating that these radio altimeters can be relied upon to perform their intended function when operating beyond a certain protection radius around 5G C-Band transmitters.” The agency said that its first related actions on C-Band protection were based on conservative estimates of impacts, and that it initially sought to protect against interference during take-offs and landings within a two-nautical-mile circle around the ends of runways.
“After some time and an improved understanding of the C-Band signals and their effects on specific radio altimeters, the FAA was able to reduce the protected area around the ends of runways,” the agency said int he NPRM—first, by defining a rectangular protected airspace, then shifting that to a trapezoidal protection zone that allowed for expanded neighboring 5G signals. “The FAA is now able to assess the 5G C-Band transmissions’ impact to aviation operations in a specific area, taking into account the particularities of the signal and the airport environment. This assessment process is the Signal in Space (SiS) analysis. It includes a 3-dimensional model for the runway safety zone and considers base station heights and terrain around the airport,” the FAA said.
The FAA said that since it began soliciting reports of potential C-Band interference impacts, it received more than 420 reports of radio altimeter anomalies happening within the areas of known 5G C-band deployments. Most of those—about 315—were ultimately determined to have other causes and resolved through normal operational safety procedures, the agency said. But, it added, “for roughly 100 of the anomaly reports occurring within NOTAM areas, the FAA has excluded other potential causes for the anomaly, but could not rule out 5G C-Band interference as the potential source of the radio altimeter anomalies.”
Those 100 incidents included “erroneous Terrain Awareness and Warning System (TAWS) warnings, erroneous Traffic Collision Avoidance System (TCAS) warnings, erroneous landing gear warnings, and the erroneous display of radio altimeter data. … The FAA is concerned that to the extent 5G C-Band operations contributed to such events, the effects will occur more frequently as telecommunication companies continue to deploy 5G C-Band services throughout the country.”
“The radio altimeter modifications that would not require a substantial system redesign, allowing aircraft operators to readily replace radio altimeters or install filters that allowed the aircraft to operate safely in a mitigated 5G environment,” the agency said, adding that some altimeters will also be able to demonstration that level of performance without any modification. The FAA estimated that the modifications would affect about 7,993 aircraft registered in the U.S.
Vodafone Germany plans to activate 2,700 new 5G cell sites with a total of 8,000 antennas in the first half of 2023, the telco said today in a press release. The company has so far connected 80% of the German population with 5G. It has activated 5G at 12,000 sites with more than 36,000 antennas altogether. For the 5G expansion, Vodafone Germany is relying on frequencies in the 3.6 GHz, 1.8 GHz and 700 MHz bands in large urban areas, residential areas and suburbs, and rural areas across Germany.
During 2022, Vodafone technicians commissioned 5,450 5G sites with more than 16,000 antennas. In total, Vodafone has already equipped 36,000 antennas with 5G, the company has said. The network operator said its 5G network is already providing coverage to 65 million people across the country, representing nearly 80% of Germany’s population.
Vodafone Germany had previously noted that its 5G Standalone (SA) network is currently available to nearly 20 million people across Germany. Vodafone previously said that 5G SA technology will reach nationwide coverage by 2025. The German telco had already deployed over 3,000 base stations for the provision of 5G SA services. Vodafone initially launched its 5G network in Germany in 2019, using 3.5 GHz frequencies that it acquired from Telefónica in 2018.
The telco also said it will continue to expand its LTE infrastructure across the country. Nationwide, Vodafone said it currently supplies around 98% of households with LTE.
“In 2023, Vodafone will bring the LTE mobile communications standard to even more people and to even more places: almost 1,900 expansion measures are pending in the first half of the year to set up new stations, carry out modernization work and install additional LTE antennas at existing stations,” Vodafone said.
“Together with Altice, Vodafone will start Germany’s largest fiber optic alliance in spring 2023, subject to the approval of the antitrust authorities. The goal is to supply up to 7 million households with new fiber optic connections in the next 6 years,” Vodafone added.
Vodafone Germany had recently successfully completed a field test with Open RAN (O-RAN) technology in Plauen, in the Saxony region.
The German carrier had recently announced that it will carry out comprehensive pilot projects for open 5G radio access networks at several locations in Germany. The first two stations for the operator’s O-RAN technology are located in rural Bavaria. The pilots are scheduled to start in early 2023 and mark the beginning of a broader deployment of O-RAN technology in Vodafone’s European mobile networks.
The pilot projects will use O-RAN hardware and software, which Vodafone successfully tested in the U.K. earlier this year. Samsung is currently supplying mobile technology and software for these O-RAN trials.
Separately, Vodafone has agreed to sell its Hungarian division for €1.7billion (£1.5billion) to local telecoms company 4iG and the Hungarian state. The sale is expected to be completed this month, with the proceeds to be used to pay off some of Vodafone’s debt.
The number of connected vehicles globally is set to grow from 192 million this year to more than 367 million in 2027, with 5G connectivity set to play a key role in the development of the market, according to a new report from Juniper Research. The company’s new Connected Vehicles research report provides an independent analysis of the future evolution of this fast-paced market and advanced connectivity solutions within the automotive industry. It provides a comprehensive study of the increase in constant connectivity technology features in cars being adopted by automotive original equipment manufacturers, how the rise of 5G is impacting the connected cars market expansion, and the key role mobile network operators have in driving the market forward in order to offer advanced connectivity and an enhanced driving experience.
The analyst firm believes the growth will be driven by improvements in both advanced driver assistance systems (ADAS), the attraction of enhanced in-vehicle infotainment systems, and the transformative potential of 5G’s high-speed and low-latency capabilities. However, maximizing 5G’s potential impact will require “effective collaborations between automotive OEMs and [mobile network] operators,” according to the authors of the report, who believe the 5G connectivity opportunity presented to telcos by the connected vehicle sector will be worth US$3.6bn in 2027.
According to the co-author of the research, Nick Maynard, “5G can allow automotive OEMs [original equipment manufacturers] to upgrade the in-vehicle experience. In a vehicle market transitioning to electric vehicles, improving the user experience is key. Operators hold the critical role in enabling this in a reliable way, making them the partners of choice as their 5G networks rapidly expand.” Connected vehicles utilising 5G will be able to exchange information “between the various elements of the transport system and third-party services.”
Key Market Statistics

2023 – 2027 Market Growth:
91%
The report is upbeat overall, but notes that commercial use cases are proving more difficult to find and justify than those for ordinary automobile drivers. According to the Juniper Research team, by 2027 commercial vehicles will account for no more than 20% of connected vehicles worldwide, only a slight increase from the 16% that commercial vehicles will account for this year.
The research shows that such slow uptake is because commercial vehicle design is not yet fully exploiting the potential of connectivity beyond simple emergency call features and basic connected infotainment systems. The report recommends that automotive OEMs prioritize integrations with common fleet tracking systems out of the factory to maximise the benefits of connectivity, and to enable commercial fleet owners to maximize efficiency in their processes.
All types of connected vehicle technologies are still ‘works in progress,’ according to Juniper Research.
Various types of connected vehicle technologies are being pursued and improved. Vehicle-to-infrastructure (V2I) connectivity is used mainly to ensure vehicle safety as the vehicle communicates with road infrastructure and shares and receives information, such as traffic flows, road and weather conditions, speed limits, accident reports, and so on. Meanwhile, vehicle-to-vehicle (V2V) connectivity primarily permits the real-time exchange of information between vehicles.
Vehicle-to-cloud (V2C) connectivity is enabled via 4G/LTE networks and is mainly used for downloading over-the-air (OTA) vehicle updates, remote vehicle diagnostics or to connect with internet of things (IoT) devices. Vehicle-to-pedestrian (V2P) connectivity is a newer safety technology that uses sensors to detect pedestrians and other ‘obstacles’ and provides collision warning and avoidance guidance. Lastly, vehicle-to-everything (V2X) connectivity is exactly what it says it is – the combination of all the above connectivity systems and methods.
Of course, connected vehicle technology is not solely concerned with conventional automobiles. Self-driving vehicles will also exploit connection technologies to communicate with the road infrastructure and cloud platforms, but as incidents of crashes, injuries and deaths proliferate, self-driving vehicles are getting some bad press and would-be user enthusiasm is waning. Again, much stock is again being placed on the ability of 5G to help make self-driving vehicles not only safer but much more intelligent and responsive – it is very much a work in progress.
