6G news and analysis for the week ending Friday 3rd October, 2025.
The US Department of Defense made the most significant move this week, awarding a contract to DeepSig and Software Radio Systems (SRS) to build an open-source 5G/6G RAN software stack under the OCUDU initiative. The project, coordinated through the Linux Foundation and backed by the DoD’s FutureG Office, aims to create what SRS CEO Paul Sutton described as “the Linux of RAN” — a neutrally governed, carrier-grade platform that could fundamentally alter the balance of power between proprietary vendors and the open-source community. With both companies already active in 3GPP and AI-RAN circles, this is not a research exercise; it is a deliberate attempt to build an alternative ecosystem for defence and beyond.
Meanwhile, an important technical debate is gaining traction in standards circles. The IEEE Communications Society blog highlights that several major companies, including Apple, Nokia, Deutsche Telekom, SK Telecom and AT&T, have proposed dropping peak data rate requirements from the ITU-R’s IMT-2030 technical performance specifications. Their argument is straightforward: 5G’s 20 Gbps downlink target was never achieved in any commercial network, and setting similarly unrealistic benchmarks for 6G risks repeating the same credibility gap. This is a debate worth watching closely as it could reshape how 6G performance is defined and marketed.
On the regulatory front, India’s TRAI launched a formal consultation on spectrum auctions that includes the upper 6 GHz bands earmarked for 6G, while Nokia Bell Labs and Bosch demonstrated integrated sensing and communication capabilities at Germany’s ARENA2036 research facility, offering a concrete glimpse of how 6G networks could function as environmental sensors.
Key announcements this week
DoD funds open-source 5G/6G RAN stack
DeepSig, an AI-native wireless communications company, announced it has been awarded a contract by the US Department of Defense’s FutureG Office to lead the OCUDU initiative, which is an open-source 5G/6G distributed unit (DU) and central unit (CU) ecosystem. DeepSig will partner with Software Radio Systems (SRS), developer of the widely used srsRAN software, with the project coordinated through the Linux Foundation.
What’s new: The OCUDU project will deliver a scalable, carrier-grade RAN software stack for 5G, 6G and AI-RAN. SRS CEO Paul Sutton said the initiative is “creating the ‘Linux of RAN’ — a neutrally-governed, carrier-grade, and open-source software platform for 5G, 6G, and beyond.” The srsRAN software will be transitioned to Linux Foundation governance as part of the project. DeepSig CEO Jim Shea said the initiative will “deliver an open CU and DU reference implementation that advances interoperability, security and fuels innovation across defense applications.”
Why this matters: The DoD has long been concerned about vendor lock-in in military communications, where proprietary systems restrict flexibility and slow innovation. By funding an open-source alternative that adheres to both 3GPP and O-RAN Alliance specifications, the Pentagon is signalling that it wants a modular, hardware-agnostic RAN that can be deployed across diverse architectures. The involvement of the Linux Foundation provides a governance model that could attract broader industry participation beyond defence. DeepSig already submitted to the 3GPP 6G Workshop in March 2025, advocating for AI-RAN as “a path to more resilient, performant and efficient air interfaces.”
Implications for 6G standards: The project’s adherence to 3GPP and O-RAN specifications means its outputs could influence how open-source implementations are validated against future 6G standards. If the stack gains traction, it could provide an alternative testing and prototyping platform for 6G research, particularly in AI-native radio design.

Should 6G drop peak data rate targets?
An opinion piece on the IEEE Communications Society Technology Blog by Alan Weissberger examines whether peak data rates should continue to be specified for IMT-2030 (6G) networks, given that IMT-2020 (5G) targets were never achieved in commercial deployments. The ITU-R’s 20 Gbps downlink and 10 Gbps uplink targets for 5G remain theoretical maximums achievable only in controlled test environments.
What’s new: Several major industry players — including Apple, Nokia, Telecom Italia, Deutsche Telekom, SK Telecom, Spark NZ and AT&T — have proposed not defining IMT-2030 peak data rate requirement values, nor maintaining the 5G peak data rate numbers. The article details how the gap between specification and reality has grown across 5G’s three frequency ranges, with typical user-experienced speeds of a few hundred Mbps on low-band falling far short of the headline 20 Gbps target. The latency gap is equally stark, with commercial 5G typically delivering 5–20 ms against the 1 ms URLLC specification that was never fully completed in 3GPP Release 16.
Why this matters: Peak data rates have historically been the most visible marketing metric for each mobile generation, setting expectations that commercial networks rarely meet. The proposal to drop these targets for 6G reflects a growing consensus that the industry’s credibility is better served by specifying user-experienced rates — the performance people actually encounter. SK Telecom’s 3GPP 6G Workshop submission explicitly emphasised “user-experienced data rates over peak rates,” and this debate is now moving into the formal ITU-R specification process. If adopted, it would represent a fundamental shift in how mobile generations are defined and compared.
Implications for 6G standards: The outcome will be determined in ITU-R WP5D through the IMT-2030.TECH PERF REQ document. If peak data rates are dropped or de-emphasised, it would align the ITU framework more closely with the pragmatic approach many 3GPP members are already advocating, where real-world performance and total cost of ownership matter more than theoretical maximums.

India’s TRAI consults on 6G-ready spectrum roadmap
India’s Telecom Regulatory Authority (TRAI) has released a consultation paper on the auction of radio frequency spectrum across multiple IMT bands, including frequencies earmarked for future 6G use. The Department of Telecommunications requested TRAI’s recommendations on reserve prices, band plans, block sizes and auction timing.
What’s new: Beyond existing bands (800 MHz through 26 GHz), TRAI has been tasked with examining auction timing for the upper 6 GHz spectrum in the 6425–6725 MHz and 7025–7125 MHz ranges, which have been standardised internationally for IMT use. The regulator is also revisiting the 600 MHz band, which attracted no bidders in 2022 due to an underdeveloped equipment ecosystem, and the 1427–1518 MHz range. The consultation follows a disappointing June 2024 auction where only 141.40 MHz was sold from over 10,500 MHz offered. Stakeholder comments are due by 28 October 2025.
Why this matters: The upper 6 GHz band is one of the most contested spectrum debates globally, with countries taking divergent positions on licensed IMT use versus unlicensed Wi-Fi allocation. TRAI notes that Hong Kong, the UAE, Sri Lanka and Brazil have already moved towards IMT adoption in this band. India has de-licensed the lower 6 GHz band (5925–6425 MHz) for Wi-Fi, making its approach to the upper portion particularly significant. The weak demand in recent Indian spectrum auctions — with key bands like 3300 MHz remaining unsold — adds complexity, suggesting operators may be cautious about further investment ahead of clearer 6G economics.
Implications for 6G standards: How India allocates the upper 6 GHz and 7 GHz bands will feed directly into the global spectrum landscape that 3GPP specifications must accommodate. India’s TSDSI is a 3GPP Organisational Partner with 54 member companies, meaning its regulatory decisions carry weight in the standards process.

Nokia Bell Labs demonstrates sensing as a “digital sixth sense”
Nokia Bell Labs, in collaboration with Bosch, has demonstrated a 6G communications and sensing system at the ARENA2036 research institute near Stuttgart, Germany. The system uses signal reflections to detect the distance, direction and speed of objects, constructing a dynamic digital twin of its physical environment in as little as 20 milliseconds. The work was profiled by MIT Technology Review.
What’s new: Peter Vetter, President of Bell Labs Core Research at Nokia, described the network as “a new sensing modality” that can “augment our real-time understanding of the physical world.” Beyond wireless sensing, the article details Nokia Bell Labs’ breakthrough in optical frequency domain reflectometry (OFDR), which enables fibre sensing over thousands of kilometres in subsea cables — potentially turning the world’s 500-plus submarine cable systems into tsunami and earthquake early warning networks. Early work on quantum sensing for applications such as higher-sensitivity MRI scans was also highlighted. Vetter said: “We are at a tipping point for sensing technologies.”
Why this matters: Integrated sensing and communication (ISAC) is one of the defining new capabilities proposed for 6G, featured in virtually every major 3GPP 6G Workshop submission. The ARENA2036 demonstration grounds the concept in practical applications: pausing factory machinery as it approaches workers, detecting vehicles around corners, and identifying drones in commercial airspace. Crucially, these capabilities would exploit standard 6G base stations rather than requiring dedicated radar hardware, potentially reducing deployment costs. The subsea cable sensing work extends the concept to fixed infrastructure, offering governments a practical early warning system using existing fibre networks.
Implications for 6G standards: ISAC is an active 3GPP study item and a core element of the ITU-R IMT-2030 framework’s new capabilities. The EU allocated €127 million for 16 6G R&D projects in 2024, and the US DoD’s FutureG office has spoken about ISAC as a military tool. The wireless and optical sensing demonstrations from Nokia Bell Labs feed directly into the evidence base that standards bodies will use to define ISAC requirements.

Nokia pushes sustainability-by-design for 6G networks
Sustainability Magazine profiled Nokia’s approach to embedding sustainability into 6G network design from the outset, covering its five Sustainability-by-Design (SbD) principles and the broader industry shift towards net zero strategies. Subho Mukherjee, Vice President and Global Head of Sustainability at Nokia, said: “Digital technologies underpin critical aspects of our lives, but we have a responsibility to ensure the cost of these benefits is not paid for by future generations.” We covered Nokia’s Sustainability-by-Design framework in detail in the 12 September newsletter, but this article adds detail about the SUSTAIN-6G consortium and climate resilience.
What’s new: The article highlights the SUSTAIN-6G project, a European Lighthouse initiative bringing together 24 partners from 10 countries to define sustainability requirements for 6G, validate new operational methods and influence international standards. It also covers the industry’s shift from traditional KPIs like throughput and latency towards sustainability-focused Key Value Indicators (KVIs) measuring energy consumption and carbon footprint. The radio access network is identified as accounting for approximately 80 per cent of energy consumption during network operation.
Why this matters: Climate resilience is emerging as a design requirement for 6G in ways that previous generations did not face. Physical infrastructure is increasingly vulnerable to extreme weather, and regulations such as the EU’s Corporate Sustainability Reporting Directive (CSRD) are imposing disclosure obligations on network operators. The focus on machine learning, digital twins and predictive maintenance for automated power savings represents a practical path to reducing energy consumption, not just an aspirational target.
Implications for 6G standards: Nokia is promoting its SbD approach into ITU, ETSI, ISO, IETF and 3GPP standards. The 3GPP SA1 working group is already considering sustainability aspects in 6G use case and service requirement definitions. The SUSTAIN-6G consortium’s involvement of operators, standards bodies and research institutes gives it a direct channel to influence how sustainability metrics are embedded in 6G specifications.

Southeast Asia and Hong Kong chart uneven paths to 6G
Thailand Business News published a country-by-country analysis of 5G and 6G prospects across Southeast Asia and Hong Kong, examining how geography, regulation and economics are shaping different trajectories. The piece also surveys the wider Asian 6G landscape including China, Japan and South Korea.
What’s new: Indonesia faces high spectrum fees and an affordability gap limiting 5G device uptake, but a large mobile-first population and growing industrial demand for private networks. Thailand has one of Southeast Asia’s most advanced 5G infrastructures but struggles with low average revenue per user (ARPU) and monetisation challenges. Hong Kong’s compact geography suits dense 5G deployment, but intense operator competition and political sensitivities influence vendor selection and spectrum allocation. The article notes China’s dominant position with state-backed 6G initiatives and a commanding lead in patents, while South Korea’s Samsung and LG Electronics continue 6G terahertz demonstrations with KAIST. Japan’s NTT DoCoMo, Sony and NEC are investing in merging communications, sensing and AI.
Why this matters: The Asian 6G landscape is not monolithic. While China leads on patents and prototypes, the practical 5G-to-6G transition in emerging Southeast Asian markets will be shaped by operator economics, device affordability and regulatory frameworks. Thailand’s Eastern Economic Corridor positions the country as a regional smart factory hub, and Indonesia’s industrial sectors are beginning to pilot private 5G networks. The commercial viability challenge — building ultra-dense 6G networks without clear business models — is acute across the region.
Implications for 6G standards: The diversity of Asian market conditions reinforces the need for 6G standards to accommodate a wide range of deployment scenarios, from dense urban Hong Kong to Indonesia’s archipelagic geography. The geopolitical dimension of standardisation — with different blocs competing to define 6G rules — could lead to fragmentation if not managed carefully within 3GPP and ITU processes.
