SK Telecom and Thales Trial Post-quantum Cryptography to Enhance Users’ Protection on 5G SA Network
Korean telco SK Telecom and digital security firm Thales have tested quantum-resistant cryptography based on a 5G standalone (5G SA) network. The trial is focused on encrypting and decrypting identity data on a 5G network to protect user privacy from future quantum threats. It was performed using Thales 5G Post Quantum Cryptography (PQC) SIM cards and a trial 5G standalone network environment from SKT. The test involved cryptographic algorithms designed to resist attacks from quantum computers, as well as ‘classical’ computers.
The end user identity on the 5G SA network is concealed and secured on the device side via the 5G SIM card. The security mechanisms involve cryptographic algorithms designed to resist attacks from future quantum computers, providing a level of security that is considered robust in the post-quantum era.

The U.S. National Institute of Standards and Technology (NIST) has been leading an initiative to standardize post-quantum cryptographic algorithms, and SKT and Thales have used the Crystals-Kyber one for this successful real condition trial. These post-quantum secure algorithms are being developed to withstand attacks from both classical and quantum computers.
“This collaboration between SKT and Thales highlights our commitment to staying ahead of the curve in terms of cybersecurity and ensuring the safety of our customers’ data. PQC provides enhanced security through the use of cryptographic algorithms that are thought to be secure against quantum computer attacks. Going forward, we will combine PQC SIM with our additional Quantum expertise to achieve end-to-end quantum-safe communications,” said Yu Takki, Vice President and Head of Infra Technology Office of SKT.
“As quantum computers have the potential to break certain existing cryptographic algorithms, there is an emerging need to transition to cryptographic algorithms believed to be secure against quantum attacks. For 5G networks, Thales started to invest on cryptographic algorithms that are quantum-resistant to enhance continued communications security and privacy for users,” said Eva Rudin, SVP Mobile Connectivity & Solutions at Thales.
As quantum computing gets more reliable and presumably starts getting used more widely in the future, this type of security is going to become increasingly important. Nokia recently announced it had completed a proof of concept trial alongside Greek research consortium HellasQCI, demonstrating what it calls quantum-safe connectivity infrastructure.

SKT Develops Technology for Integration of Heterogeneous Quantum Cryptography Communication Networks
SK Telecom and Deutsche Telekom to Jointly Develop Telco-specific Large Language Models (LLMs)
Daryl Schoolar: 5G mmWave still in the doldrums!
In November Recon Analytics completed a survey of 100 communication service providers (CSP) as part of its “Global Communication Service Provider Pulse” research practice. The survey included questions around the current state of their 5G networks, and their thoughts on 5G Advanced and 6G. Three of those questions are as follows:
- What has been the biggest benefit of deploying 5G?
- In the next phase of 5G’s development, also known as 5G-Advanced, several technological enhancements are under study or being developed. From the list below, which three possible 5G-Advanced technology areas do you think are the most important?
- What are the most important technology areas that you think 6G should focus on?
The most common answers to all three of those questions had to do with increasing network capacity and gaining access to new spectrum. And this is where having lots of water but nothing to drink comes into play. There are mobile operators today who already have large swaths of fallow spectrum in the form of mmWave.
mmWave [1.] provides mobile operators with thousands of megahertz of new capacity, but the majority of 5G operators (with the exception of Verizon) have not started to use it. The limited deployment reflects the coverage and in-building penetration challenges that come with mmWave. Our survey findings underscore this reality. Recon asked mobile operators who currently have a commercial 5G network if they were using mmWave spectrum, below are the responses we got back.
Note 1. 5G mmWave is a set of 5G frequencies that can provide ultra-fast speeds over short distances. It operates on wavelengths between 30 GHz and 300 GHz, which is higher than 4G LTE’s wavelengths of under 6 GHz.
Of the 100 operators we surveyed 66% have a commercial 5G network. Of that group, 35% say they have deployed 5G for mmWave. 44% of the respondents have mmWave spectrum but are either focused on building their network in other spectrum bands, or don’t currently see a commercial reason to use mmWave. The ongoing underutilization of 5G mmWave seems to be impacting the current outlook for future 6G spectrum as well.
When asking mobile network operators about what they thought were the most important areas 6G should focus on, the most common answer given was more capacity through new spectrum. Originally, industry discussions on new 6G spectrum bands were focused on terahertz, which would be even more challenging to work with than mmWave. In the last year there has been a shift. 6G spectrum discussions have moved to the possibility of using bands in the 7 GHz to 24 GHz range. While these bands still have their difficulties when it comes to coverage and in-door penetration, they are not as problematic as terahertz or in many cases mmWave. However, this change in thinking around 6G spectrum does not change the challenges mobile operators must deal with today when it comes to mmWave.
That is where companies like Pivotal Commware and ZTE can be of assistance. Pivotal Commware has pioneered 5G mmWave repeaters that allow a mobile network operator to improve signal range and coverage at a fraction of the cost of an additional mmWave radio. This helps to improve the economics of using mmWave for 5G. Verizon has publicly acknowledged that it is working with the vendor in the U.S. In Asia, ZTE has been working on a solution of its own to overcome line of sight issues with mmWave that it calls RIS 2.0. AIS (Thailand) has trialed RIS 2.0.
Mobile operators’ desire for more capacity is not going away, especially with the emergence of fixed wireless access. The challenge is finding new ways to meet those capacity needs. Operators can continue to milk lower bands and squeeze capacity improvements out of them, but that will only take them so far. mmWave and other higher spectrum bands are well suited to meet growing capacity requirements, but it will require the development of repeaters and reflective services to make those higher bands easier to use for 5G and eventually 6G. It doesn’t help operators to be surrounded by a spectrum they cannot effectively employ, like sailors at sea with no drinkable water in sight.
Daryl Schoolar is a director and analyst at Recon Analytics where he focuses on telecommunication service providers and companies that provide networking communication solutions to those service providers. Some of the topics he covers are digital transformation, 5G, 6G, cloud networking, and telecom service strategies.

Broadband Forum SDN/NFV Work Area launches four new projects at Bangkok Q4-2023 meeting
Introduction:
The Broadband Forum says their open standards and open broadband projects continue to deliver vital importance to companies, both small and large, as we focus on the latest industry trends, and extract most value to consumers, and transition to services-led broadband.
Progress on cloud based SDN/NFV was one of many accomplishments at this December’s meeting in Bangkok, Thailand. SDN and NFV are both software components, but they are different. SDN virtualizes the management of networks, while NFV converts network processes into software applications. SDN separates the data and control planes, allowing operators to manage features from a centralized location. NFV virtualizes network infrastructure, separating functions that typically run in hardware and implementing them as software. We believe the Forum’s SDN/NFV activity is very important as neither SDN or NFV have lived up to their potential and promise, primarily because they were premises based, rather than implemented in the cloud.
From a business perspective, the migration to SDN and NFV in the broadband network facilitates agile deployment of new customized distributed broadband services and applications. This enables new revenues and provider differentiation while managing Capex and OpEx both in the access network and in single and multi-tenant residential and business locations by implementing an agile network and enabling autonomous and automated operations.
Project Scope: Includes migration to and deployment of SDN/NFV-enabled implementations across all aspects of the broadband network. The scopes are:
- the definition of a new cloud-based environment with its related requirements, called Cloud-based Central Office (CloudCO)
- the architectural requirements, the interface specification among all the components with their related data models including the control-user plane separation interface for disaggregated access nodes
- the specification of virtual network functions and interface with their related data models
- the definition of requirements, interfaces and data models for autonomous and automated networks
Target: Define the Cloud-based Central Office (CloudCO) architecture using SDN, NFV, and cloud technologies to support network functions fundamentally redefining the architecture of access and aggregation networks. Support the migration of SDN and NFV into all aspects of broadband networks, facilitating the agile deployment of new distributed broadband services and applications for operators with greater operational efficiency and lower cost.
Progress: The SDN/NFV Work Area continues to progress the CloudCO project for virtualized network functions, SDN management and control and domain orchestration capabilities in a broadband network. The main activities currently ongoing are related to the disaggregation of the Access Node and defining the related interfaces. The Cloud Component Project Stream is continuing work on Automated Intelligence Management (AIM), Smart SD-WAN and virtual OMCI.
Three key documents near completion. TR-486 is set to be published in December 2023, WT-477 moves to Final Ballot, and WT-386 Issue 2 is currently resolving Straw Ballot comments.
Outcomes:
A productive quarterly meeting for the SDN/NFV Work Area saw four new projects approved. This was WT-403 Amendment 1 ‘PON Abstraction Interface for Time-Critical Applications’, WT-384 Issue 2 ‘CloudCO 2.0’, WT-436 Issue 2 ‘AIM Framework and Architecture’, and a project on Broadband Network Data Collection (BNDC).
A new Open Broadband proposal on CloudCO App SDK was presented to the Broadband Forum Board of Directors.
WT-477 on access node disaggregation has finished Straw Ballot review for both the baseline document and data model. The project has been approved to move to Final Ballot.
WT-413 Issue 2 on ‘SDN Management and Control Interfaces for CloudCO Network Functions’ is progressing. Previously, the SDN/NFV and Common YANG Work Areas reviewed the approach and agreed to report a detailed list of data models, so that vendors can rapidly discover the data models to be implemented for each access network function. The group will discuss the scope regarding the addition of ONU (Optical Network Unit) management and BAA chapter update before the Spring 2024 Meeting. The document is expected to enter Straw Ballot review once WT-477 and WT-486 are completed.
On the Artificial Intelligence and automation fronts, WT-486, which specifies the interfaces for the Automated Intelligence Management (AIM) framework specified in TR-436, has completed Final Ballot and will be published in December 2023. An AIM Tiger Team has completed gap analysis in WT-436 Issue 2 and WT-486 Issue 2. The Tiger Team discussed the Broadband Network Data Collection new project proposal and received approval from the group.
Straw Ballot comment resolution has been completed and WT-386i2 on Fixed Access Network Sharing.
A Tiger Team has been established to review the document on CloudCO interfaces (WT-411i2/WT-454i2) to include the Access SDN Management and Control northbound interface intent-based interactions addressing access network topology and abstraction, including inventory. An update was presented on the discussions held on the data models. The Metamodel needs further review and will be discussed in future weekly meetings.
Together with the Common YANG, the group held a joint session to discuss a new project for BAA – Access Device Abstraction Manager (BAA-ADAM). The groups will continue the discussions offline to clarify the scope and impact on CloudCO interfaces.
The group took part in this year’s CloudCO Demo at Network X in October. Key projects were involved in the demo, including WT-477 reference Disaggregated – Optical Line Terminal (D-OLT) Virtual Network Function, Northbound interface exposure of a L2-L3 network abstraction, Optical Network Terminal (ONT) telemetry over virtualized ONU Management and Control Interface (vOMCI), automation test-suite for OB-BAA, IPFIX adapter framework, and vOMCI Plugfest delta features.

WRC-23 concludes with decisions on low-band/mid-band spectrum and 6G (?)
The World Radiocommunication Conference 2023 (WRC-23) [1.] in Dubai, UAE ended on Friday. Regulators agreed on new mobile low-band spectrum (below 1 GHz) and mid-band spectrum in the 3.5 GHz and 6 GHz ranges. They also discussed 6G (which is an oxymoron to this author since the many problems we’ve identified with 5G have not been resolved).
Note 1. WRC’s are held every four years under the auspices of the International Telecommunication Union Radio communications sector (ITU-R). They are intended to harmonize spectrum usage across the world so that network operators, equipment vendors and others can avoid international fragmentation and leverage global economies of scale.
“WRC-23 has provided a clear roadmap for mobile services to continue to evolve and expand for the benefit of billions across the globe,” said John Giusti, Chief Regulatory Officer at the GSMA. “The GSMA believes that no-one should be left behind in the digital age and the decisions of WRC-23 will allow us to deliver a brighter future where mobile brings communities together, delivers industrial agility and provides economic growth. Implementation of the WRC-23 decisions will support global digital ambitions, deliver greater digital equality and unlock the full power of connectivity.”
The detailed WRC-23 provisional final acts may be read here.
……………………………………………………………………………………………………………………………………………………………………..
Final harmonization of the 3.5 GHz band (3.3-3.8 GHz) – the pioneer 5G band – was achieved across Europe, the Middle East and Africa (EMEA) as well as throughout the Americas.
A new band – the 6 GHz band (6.425-7.125 GHz) – was identified for mobile in every ITU Region – EMEA, the Americas and the Asia Pacific. Countries representing more than 60% of the world’s population asked to be included in the identification of this band for licensed mobile at WRC-23. The 6 GHz spectrum is now the harmonized home for the expansion of mobile capacity for 5G-Advanced and beyond.
“The 6GHz band is the only remaining mid-band spectrum currently available to respond to the data traffic growth in the 5G-Advanced era,” GSMA said in a statement. As the primary international organization representing the 5G industry, it has been pushing for 5G operations in the 6GHz band. “The WRC-23 decision to harmonize the 6GHz band … is a pivotal milestone, bringing a population of billions of people into a harmonized 6GHz mobile footprint. It also serves as a critical developmental trigger for manufacturers of the 6GHz equipment ecosystem,” GSMA said.
ITU-APT Foundation of India said the agreement also opens the path for opening the lower 6 GHz band from 5925-6425 MHz for unlicensed usage to promote innovation in the country.
However, the 6 GHz band approval at WRC-23 may not affect the U.S. market. U.S. regulators at the FCC in 2020 reserved the entire 6GHz band for Wi-Fi and other unlicensed operations, over the objections of the 5G industry.
“If the United States doesn’t present alternative frequency ranges for 5G services that can be internationally harmonized, 5G operations in the 6GHz band could be adopted in more regions. This would allow Chinese equipment to proliferate in regions where the plan is adopted, setting back efforts to make Wi-Fi 6 in the band an international standard,” warned Jeffrey Westling, director of technology and innovation policy at the American Action Forum US nonprofit, in a post published prior to the start of WRC-23.
Jessica Rosenworcel, chairwoman of the FCC, approved the WRC-23’s work. “The WRC was not just weeks of work in Dubai, but also years of preparation by the FCC, experts across the government, and our telecommunications industry,” she said in a statement. “The delegation’s accomplishments will promote innovation in unlicensed spectrum including Wi-Fi, support 5G connectivity, pave the way for 6G, and bolster U.S. leadership in the growing space economy. We now look forward to getting to work on preparations for WRC-27.”
“Thank you to Deputy Assistant Secretary Steve Lang for his able leadership and to the FCC staff along with the entire U.S. delegation for their exceptional and tireless efforts at WRC-23,” said FCC Commissioner Anna M. Gomez in a statement. “WRC-23 was the culmination of years of collaboration and hard work between our strong interagency team, the telecommunications industry, and our regional and international partners. The delegation’s accomplishments on terrestrial licensed and unlicensed spectrum as well as space allocations will advance science and economic prosperity worldwide.”
The U.S. Department of State also issued a media note on the delegation’s work at WRC-23 here.
The Wi-Fi Alliance, a U.S. trade group designed to promote the technology in unlicensed bands, also cheered the new 6GHz decision at the WRC-23. The association supported the FCC’s decision to allocate the entire 6GHz band for unlicensed operations.
“The conference adopted an international treaty provision to explicitly recognize that this spectrum is used by wireless access systems such as Wi-Fi,” the Wi-Fi Alliance said in a statement about the WRC-23 decision on 6GHz. The Wi-Fi Alliance noted that WRC-23 identified the 6GHz band for licensed operations in Europe, Africa and a few other countries, but not globally.
………………………………………………………………………………………………………………………………………………………….
WRC-23 also set out a path towards greater digital equality by defining mobile use of more low-band spectrum in the 470-694 MHz band in EMEA. Low bands can help expand capacity for the internet connectivity of rural communities as their signals reach over wide areas. WRC-23’s new low-band mobile allocations will be an important tool to break down the barriers towards digital equality in the EMEA region and lower the urban/rural connectivity divide.
“Over half the world is connected to the mobile internet today,” said Luciana Camargos, Head of Spectrum at the GSMA. “But, as mobile connectivity develops, we need to ensure that we can deliver services for everyone. The great legacy of WRC-23 will be in allowing us to do so sustainably, affordably and in a way that delivers for the whole planet. We cannot stop here – WRC-23 is only the starting gun and now governments will need to act on its decisions, enabling new mobile technologies that embrace sustainability and unleashing the full potential of mobile to deliver a better tomorrow for our planet.”
……………………………………………………………………………………………………………………………………………………………………………
WRC-23 attendees also moved forward on the topic of 6G. Prior to the start of the three week conference in Dubai, the ITU adopted a resolution intended to guide the development of a 6G standard. During the conference, regulators agreed to study the 7-8.5GHz band for 6G in time for the next ITU conference in 2027. That spectrum band aligns with proposals from Ericsson and others for early 6G operations to sit between 7 GHz and 20 GHz.
“This global agreement [on the 7-8.5GHz band] ensures the ongoing growth of 5G around the world and paves the way for 6G from 2030 onwards,” wrote the Global mobile Suppliers Association (GSA) in a statement. “Technical work now starts to determine the sharing and compatibility of 6G with incumbent uses of the identified spectrum.”
Joe Barrett, President of GSA, commented: “The global agreement reached by ITU represents a significant milestone not just in the continued growth of 5G and 5G-Advanced connectivity, but also in the path to 6G. The entire global mobile ecosystem can now innovate with confidence and a clear sense of the spectrum requirements for 6G, both in terms of its future availability and compatibility with other users of the spectrum. At GSA we appreciate the hard work and diligence of ITU and its members that has gone into reaching this welcome global agreement at WRC-23. GSA’s Spectrum Group will continue to contribute studies and technical analysis to international, regional and individual country policymakers and regulators to facilitate the timely availability of spectrum for use by mobile network operators. As an industry, we now look forward to continued 5G growth, 6G innovation and the socio-economic benefits mobile connectivity brings globally.”
Like this author, the Financial Times is not enthusiastic about 6G:
“CB Insights shows that mentions of 5G during earnings calls peaked in 2021 and have since fallen. Network operator capital spending growth is expected to dip next year. Operators want to see better returns on their investment in 5G before they contemplate further network upgrades.”

Highlights of LightCounting’s December 2023 Quarterly Market Update on Optical Networking
LightCounting’s Quarterly Market Update report [1.] for Q3 2023 revealed that the optical communications industry financial results were disappointing.
Every financial market indicator that the market research firm tracks – ICP (Integrated Communications Provider) and CSP (Communications Service Provider) capex, datacom and networking equipment, and semiconductor (x-Nvidia) and optical components sales – all had negative growth compared to Q3 2022.
Note 1. LightCounting’s Quarter Market Update reports are designed to provide an easy-to-digest snapshot of optical transceiver growth trends, backed up by detailed quarter-by-quarter sales data collected via LightCounting’s proprietary vendor survey. Performance metrics and commentary for top-tier telecom and internet service providers, network and datacom equipment makers, and optical component and semiconductor vendors are also included to provide an understanding of what drives sales trends at the transceiver level.
- Alphabet and Microsoft had record capital expenditures.
- Arista, Broadcom, Calix, Innolight, and Nvidia all reported record revenues.
LightCounting is projecting, based on its current analysis, that sales increased in Q3 and will increase further in Q4, to a new record high, as shown in the figure below. This data includes estimates for 400G and 800G transceivers manufactured by Nvidia internally.
The expectation of growth in Q4 carries over to 2024 as well and is consistent with the guidance given by several companies ranging from Alphabet and Amazon to Coherent and Lumentum. The big caveat is that growth in 2024 will be tightly focused on AI-related infrastructure, and growth in demand for those products is expected to far outstrip demand in other segments like traditional telco and enterprise networks. Most of the growth in the optical components and modules market will come from sales of 800G transceivers.

Deutsche Telekom announced that it has successfully enabled more than 2.5 million new fiber connections this year, thereby realizing its fiber plant expansion target. The company invested EUR 2.5 billion in fiber expansion, expanding coverage in almost 3,500 towns and municipalities. According to the announcement, the company projects a total investment of EUR 30 billion in the fiber optic rollout by 2030.
Its Fiber-to-the-home (FTTH) network is set to reach eight million households by the end of the year, with plans to extend this to ten million fiber optic connections by 2024.
………………………………………………………………………………………………………………………………………..
In mobile, Deutsche Telekom currently provides 5G coverage to 96 percent of the population, serving 80 million people through a network of over 80,000 5G antennas, including 10,000 in the 3.5 GHz band spread across more than 800 cities and municipalities. The network delivers download speeds of up to 1 Gbps.
The company aims to achieve 99 percent 5G coverage for the German population by 2025 and plans to launch 5G Standalone (SA) core network for private customers in 2024. DT indicates that 10,000 antennas are compatible with 5G SA in the 3.6 GHz band, covering more than 800 cities and municipalities. This is up from 9,700 antennas in August 2023.
Deutsche Telekom’s business customers are already using 5G SA technology with functions such as network slicing. For example, for live TV transmission of media or in 5G campus networks for industry and research. “In the coming year, 5G SA should then offer all customers real added value,” DT said.
Meanwhile, rival operators Telefónica Deutschland (O2 Germany) and Vodafone Germany already offer standalone 5G services.
…………………………………………………………………………………………………………………………
DT began the deployment of its open radio access network (O-RAN) in Germany in December, in collaboration with Nokia and Fujitsu. The first O-RAN commercial deployment will be in Neubrandenburg. Nokia and Fujitsu are supplying the necessary technology components.
“Open RAN increases the choice of manufacturers and therefore our flexibility. The open access network enables more automation. And makes our networks even more resilient. This benefits the people that our mobile network connects,” says Claudia Nemat.
The German telco expects to have 3,000 O-RAN compatible antennas by the end of 2026.
…………………………………………………………………………………………………………………………
Deutsche Telekom also says it’s using Artificial Intelligence (AI) in network expansion and mobile communications. AI aids in analyzing and evaluating cell usage and capacity utilization, with the ongoing development of a large language model for telco-specific applications in collaboration with SK Telekom. Additionally, AI contributes to enhanced network security through automated pattern recognition, according to the company.

NTT advert in WSJ: Why O-RAN Will Change Everything; AT&T selects Ericsson for its O-RAN
We cover both NTT’s Open RAN ad in the WSJ and AT&T’s selection of Ericsson as their primary Open RAN vendor:
This NTT-WSJ ad was a huge shock to me as I did not expect NTT to be so optimistic about Open RAN deployments as it would cannibalize their existing 3G/4G/5G RAN. Here’s the copy/paste of the WSJ advertisement:
Introduction:
With data consumption accelerating, and demand for high-speed data soaring, the growth of the global O-RAN alliance is taking the future of connectivity to the next level.
Allowing mobile network operators to share network integration costs and enabling interoperation between different vendors’ cellular network equipment are just two of the revolutionary benefits driving O-RAN’s adoption worldwide. As a pioneer in this ecosystem, Japanese operator NTT Docomo has established the OREX brand to deliver its O-RAN solution to mobile users anticipating the instantaneous communication that 6G will bring.
Innovating the Future of Connectivity:
The expanding O-RAN universe consists of more than 300 mobile operators, vendors and academic and research institutions worldwide. With consumer 5G connections alone predicted to reach 2 billion by 2025—doubling from 1 billion in 2022—and 6G technology in sight, further adoption of O-RAN plays a vital role in the future of global connectivity. As a co-founder of the global O-RAN alliance, Japanese operator NTT DOCOMO is one of the innovators transforming mobile connectivity through open, intelligent and interoperable mobile networks.
What is O-RAN?
An open-ended, non-proprietary version of the Radio Access Network (RAN) system used for mobile networks, O-RAN stands for open radio access network (Open RAN) and is an ecosystem and architecture for flexible networks capable of leveraging 5G—and beyond—wireless communications. Using radio waves to connect users (consumer or business) to the mobile network, it allows interoperation between different vendors’ cellular network equipment. It is also a connector for accessing key web applications. Whereas RAN technology currently comes as a single-vendor hardware- and software-integrated architecture, O-RAN is a multi-supplier solution that can disaggregate hardware and software with open interfaces and virtualization.
What Are the Business Benefits?
Put simply, O-RAN reduces the total cost and increases the flexibility of network ownership for the benefit of consumers and enterprises that use sensors, smartphones and similar remote wireless devices. A clear alternative to vendor lock-in, the sharing of network integration costs among a number of mobile network operators—instead of that cost being shouldered by a single operator—makes it more competitive. As well as increased connectivity for vendors and network operators, O-RAN offers greater accessibility, technological flexibility, supply-chain diversity, and scalable mobile networks. New features are introduced quickly via software, reducing maintenance time while also making further innovation and greater competition possible. NTT Docomo’s OREX has been established to deliver its O-RAN solution, providing robust support for international operators and a customized user experience.
Opening up Mobile Networks:
The global O-RAN alliance is expanding as the technology matures. Adoption is growing fastest in North America and Asia Pacific, where there is high data consumption, rising demand for high-speed data and the integration of AI and cloud computing. These two regions are predicted to dominate the global market over the next five years. In Europe, both Germany and the U.K. have established initiatives to develop and support their solutions. Leading telecom companies in the Netherlands, Spain, and Italy are developing O-RAN technology, as are two of India’s three major operators. More prospective markets exist in Asia, Africa and South America.
The Journey to 6G:
Designed to make cloud computing and the mobile internet ubiquitous, 6G-enabled technologies will greatly impact business when commercially available around 2030. Potentially 100 times faster than 5G, 6G is the next-generation technology that will enable lightning-speed device connections and O-RAN technology has the flexibility to adopt it. 6G will transform how companies communicate, process information, train employees and much more. NTT Docomo is leveraging the knowledge gained from its unique experience in building mobile networks with multiple equipment vendors since the 4G era, and its OREX offering integrates the strengths of 13 partners including Dell, Intel, Fujitsu, and others to offer a strong value proposition for the global shift to O-RAN.
……………………………………………………………………………………………….
AT&T selected Ericsson as its Open RAN equipment supplier, yet the Swedish network equipment vendor does not have any open RAN certifications with the O-RAN Alliance. AT&T said Open RAN will cover 70% of its wireless traffic in the United States by late 2026. Beginning in 2025, the company will scale this Open RAN environment throughout its wireless network in coordination with multiple suppliers such as Corning Incorporated, Dell Technologies, Ericsson, Fujitsu, and Intel.
“AT&T is taking the lead in open platform sourcing in our wireless network,” said Chris Sambar, Executive Vice President, AT&T Network. “With this collaboration, we will open up radio access networks, drive innovation, spur competition and connect more Americans with 5G and fiber. We are pleased that Ericsson shares our supp
“High-performance and differentiated networks will be the foundation for the next step in digitalization. I am excited about this future and happy to see our long-term partner, AT&T, choosing Ericsson for this strategic industry shift – moving to open, cloud-based and programmable networks. Through this shift, and with open interfaces and open APIs, the industry will see new performance-based business models, creating new ways for operators to monetize the network. We are truly proud to be partnering with AT&T in the industrialization of Open RAN and help accelerate digital transformation in the U.S.,” said Börje Ekholm, President and CEO, Ericsson.
AT&T will use this new collaboration with Ericsson to enhance its wireless network in North America and expand the most reliable 5G network.1 The expected spend under the Ericsson contract is below what the company expects to spend for wireless capital expenditure over the next 5 years. Given the interdependence between fiber and wireless, and the increasing desire for customers to have one connectivity provider across fixed broadband and wireless, the company sees economically attractive opportunities to expand its fiber footprint in the coming years as well.

Nokia and du (UAE) complete 5G-Advanced RedCap trial; future of RedCap?
Nokia and United Arab Emirates (UAE) telco du announced the conclusion of what it claimed to be UAE’s first 5G-Advanced 5G Reduced Capability (RedCap) trial over a commercial network. Nokia said that this recent trial showcased the readiness of du’s 5G network for innovative use cases in areas such as the Internet of Things (IoT), wearables and Industry 4.0 to address 5G monetization challenges.
RedCap, sometimes referred to as (3GPP) 5G NR Light, is a reduced set of 5G capabilities intended for devices like wearables and low-cost hotspots that have low battery consumption, lower costs and lower bandwidth requirements. Introduced with 3GPP Release 17, 5G RedCap is designed for devices currently served by LTE CAT-4 but provides equivalent or better in performance with up to 150 Mbps theoretical maximum downlink throughput. This technology helps reduce the complexity, cost and size of 5G devices. The RedCap specification will be included in ITU-R M.2150-1.
……………………………………………………………………………………………………………………………………………………………………………………….
The trial participants used MediaTek’s T300 series RedCap test equipment in du’s 5G Standalone (SA) Radio Access Network (RAN) built with Nokia’s AirScale radio products, leveraging the existing mid-band Spectrum. This will follow extending RedCap over low band frequencies, ensuring extreme coverage and connectivity. Notably, the low band in 600MHz, is a vital connectivity band currently under discussion at the World Radio Conference WRC-23 taking place in Dubai.
With RedCap devices expected to be commercially available from 2024, it will significantly augment du’s diversified use case portfolio to include cost-efficient 5G home wireless, wearables, video surveillance, and wireless industrial sensors.
5G devices commonly feature intricate hardware and energy-intensive capabilities, resulting in higher cost, size, and power consumption. RedCap technology is dedicated to streamlining 5G devices, specifically targeting compact IoT devices like wearables and health trackers, as well as ruggedized routers and sensors for environmental or condition-based monitoring. These devices exhibit lower demands for battery life and reduced bandwidth requirements. RedCap ensures they sustain performance while optimizing their power efficiency. Nokia has been instrumental in driving the evolution of RedCap IoT functionality in collaboration with the telecommunications industry.
Saleem Alblooshi, Chief Technology Officer at du, said: “This collaboration introduces the revolutionary 5G-Advanced RedCap functionalities, enabling seamless connectivity of RedCap devices to cutting-edge 5G networks. Nokia’s unparalleled innovation simplifies and pioneers the development of 5G devices, particularly wearables and small IoT devices, significantly enhancing LTE-CAT4 performance and optimizing energy efficiency. These remarkable technological advancements are pivotal in propelling Industry 4.0 revolution.”
Mikko Lavanti, Senior Vice President at Nokia MEA, said: “This new collaboration between du and Nokia represents not only a significant step forward in the monetization of 5G technology but also solidifies the UAE’s position as a pioneer in the evolution of 5G use cases for society and enterprises. As the collaboration progresses, both companies are poised to revolutionize the way we experience and interact with 5G technology, unlocking unprecedented possibilities for innovation and connectivity.”
Dr. Ho-Chi Hwang, General Manager of Wireless Communication System and Partnerships at MediaTek, said: “It’s essential to bring new capabilities of 5G to the UAE, and this trial is an important step in that direction. We are proud to have provided our RedCap devices to further develop the ecosystem for 5G monetization. We hope, by pioneering the technology in the Middle East and Africa region, MediaTek will be able to assure our customers of more innovative 5G products and services coming their way.”
…………………………………………………………………………………………………………………………………………………………………
Future of RedCap:
Counterpoint Research expects that 5G RedCap modules will make up 18% of total cellular IoT module shipments by 2030—what it describes as “significant market potential, particularly in developing nations where the cost is key to wide technology adoption for digital transformation.”
“If we want to tackle some of these interesting business cases and really get the price point so the business can take off, then we need to provide the right types of options,” said Paul Harris, principal architect in the Office of the CTO at Viavi Solutions. “People don’t want to be paying for chipsets that are too performant in the wrong types of devices.” Harris also noted that standards work on RedCap continues, with a series of recommendations on reducing RedCap’s performance even further with support of just five megahertz of bandwidth, even lower data rates and reduced peak data rates as well as additional power savings in the form of Extended Discontinuous Reception (allowing longer periods during which a device can power off). While that work on “eRedCap” is still taking shape in Release 18 and additional features may be available to scale down RedCap further in Release 19. “It’s still kind of a moving target and probably will continue to be, but there will probably be different categories that get introduced of RedCap as it goes on,” he said. Harris goes on to offer up a potential vision of a RedCap market where there is a gradual progression into some parts of the market addressed with the initial Rel. 17 RedCap options, and that by Rel. 19, a scaled-back RedCap market could open up for even lower-complexity, lower data-rate devices that then leads to an explosion of 5G sensor devices.
“5G is absolutely the directional technology,” said Bill Stone, VP of technology development and planning at Verizon. “I do think it’s inevitable that we’ll be seeing all of IoT evolve over time, and it’s going to be starting as soon as next year. We’re going to see all of the IoT device community moving over to 5G, because that’s where—with 5G NR SA—we’re going to see the potential for much longer lifecycles [and] the ability to support that, to make commitments for longer-term support of IoT devices.”

Google announces Gemini: it’s most powerful AI model, powered by TPU chips
Google claims it has developed a new Generative Artificial Intelligence (GenAI) system and Large Language Model (LLM) more powerful than any currently on the market, including technology developed by ChatGPT creator OpenAI. Gemini can summarize text, create images and answer questions. Gemini was trained on Google’s Tensor Processing Units v4 and v5e.
Google’s Bard is a generative AI based on the PaLM large language mode. Starting today, Gemini will be used to give Bard “more advanced reasoning, planning, understanding and more,” according to a Google blog post.
While global users of Google Bard and the Pixel 8 Pro will be able to run Gemini now, an enterprise product, Gemini Pro, is coming on Dec. 13th. Developers can sign up now for an early preview in Android AICore.
Gemini comes in three model sizes: Ultra, Pro and Nano. Ultra is the most capable, Nano is the smallest and most efficient, and Pro sits in the middle for general tasks. The Nano version is what Google is using on the Pixel, while Bard gets Pro. Google says it plans to run “extensive trust and safety checks” before releasing Gemini Ultra to select groups.
Gemini can code in Python, Java, C++, Go and other popular programming languages. Google used Gemini to upgrade Google’s AI-powered code generation system, AlphaCode. Next, Google plans to bring Gemini to Ads, Chrome and Duet AI. In the future, Gemini will be used in Google Search as well.
……………………………………………………………………………………………………………………………………………………
Market Impact:
Gemini’s release and use will present a litmus test for Google’s technology following a push to move faster in developing and releasing AI products. It coincides with a period of turmoil at OpenAI that has sent tremors through the tight knit AI community, suggesting the industry’s leaders is far from settled.
The announcement of the new GenAI software is the latest attempt by Google to display its AI portfolio after the launch of ChatGPT about a year ago shook up the tech industry. Google wanted outside customers to perform testing on the most advanced version of Gemini before releasing it more widely, said Demis Hassabis, chief executive officer of Google DeepMind.
“We’ve been pushing forward with a lot of focus and intensity,” Hassabis said, adding that Gemini likely represented the company’s most ambitious combined science and engineering project to date.
Google said Wednesday it would offer a range of AI programs to customers under the Gemini umbrella. It touted the software’s ability to process various media, from audio to video, an important development as users turn to chatbots for a wider range of needs.
The most powerful Gemini Ultra version outperformed OpenAI’s technology, GPT-4, on a range of industry benchmarks, according to Google. That version is expected to become widely available for software developers early next year following testing with a select group of customers.
………………………………………………………………………………………………………………………………………………………………………………………………
Role of TPUs:
While most GenAI software and LLM’s are processed using NVIDIA’s neural network processors, Google’s tensor processing units (TPUs) will power Gemini. TPUs are custom-designed AI accelerators, which are optimized for training and inference of large AI models. Cloud TPUs are optimized for training large and complex deep learning models that feature many matrix calculations, for instance building large language models (LLMs). Cloud TPUs also have SparseCores, which are dataflow processors that accelerate models relying on embeddings found in recommendation models. Other use cases include healthcare, like protein folding modeling and drug discovery.

Competitors:
Gemini and the products built with it, such as chatbots, will compete with OpenAI’s GPT-4, Microsoft’s Copilot (which is based on OpenAI’s GPT-4), Anthropic’s Claude AI, Meta’s Llama 2 and more. Google claims Gemini Ultra outperforms GPT-4 in several benchmarks, including the massive multitask language understanding general knowledge test and in Python code generation.
