Open RAN

Open RAN disaggregates the radio access network, separating hardware from software and standardizing the interfaces between components so operators can mix equipment from multiple vendors rather than buying a single integrated stack. The aim is more competition, lower cost, and greater flexibility, with the O-RAN Alliance defining the key specifications. Adoption has progressed from trials toward commercial deployments, though integration complexity, performance parity, and energy efficiency remain active challenges. Open RAN intersects with virtualization, cloud-native RAN, and AI-driven optimization, and is increasingly applied to 5G and private-network builds. For operators, it reshapes vendor strategy and supply chains; for new entrants, it lowers barriers to the RAN market. This channel covers Open RAN standards, deployments, and ecosystem developments, with analysis of where disaggregation is delivering on its promises and where it still falls short.

SoftBank–DigitalBridge: AI Data Center Power Advantage

SoftBank–DigitalBridge: AI Data Center Power Advantage
A potential take‑private of DigitalBridge by SoftBank would concentrate capital, power, and build capability at the precise chokepoints of the AI and telecom stack. The center of gravity in AI infrastructure has moved from buildings and GPUs to grid access, entitlements, and construction lead time. DigitalBridge controls rights to roughly 21 GW of power across its global portfolio—effectively a banked inventory of megawatts that can be turned into contracted capacity faster than new entrants can clear interconnection queues or procure transformers. This transaction is fundamentally about compressing multi‑year build timelines for AI factories into quarters.

SK Telecom executive cuts: 30% reduction

SK Telecom executive cuts: 30% reduction
Reports indicate SK Group will reduce executive ranks by up to 30%, a move that would reshape decision-making across affiliates including SK Telecom (SKT). For SKT, which sits at the nexus of the group’s AI, cloud, and connectivity ambitions, executive trims would concentrate authority and compress approval chains at a sensitive time for 5G monetization and AI platform bets. Executive consolidation at a Tier-1 operator tends to reset priorities, procurement rhythms, and partner engagement models.

Vodafone will expand one of Europe’s largest Open RAN footprints using Dell infrastructure as part of a multi-year radio access modernization program. Dell will supply its PowerEdge XR8000 series servers, including the XR8620t and the latest XR8720t with Intel Xeon 6 SoC. Vodafone also plans to adopt the Dell Telecom Infrastructure Automation Suite (DTIAS) to provide the Infrastructure Management Service within its Open RAN architecture, designed to automate Day 0/1/2 lifecycle operations for O-Cloud infrastructure.

SoftBank and NVIDIA AI-RAN: 16-Layer MU-MIMO on GPUs

SoftBank AI-RAN Realizes - Software-only Massive MIMO on GPU
SoftBank and NVIDIA have validated a fully software-defined, GPU-accelerated AI-RAN that delivers 16-layer massive MU-MIMO outdoors—an inflection point for vRAN performance, Open RAN scalability, and AI-native RAN design. SoftBank’s AI-RAN product, AITRAS, executed the entire 5G physical layer on NVIDIA GPUs at the Distributed Unit and demonstrated stable 16-layer multi-user MIMO downlink in an outdoor trial at NVIDIA’s Santa Clara campus. The system connected to O-RAN-compliant radios via Split 7.2x and achieved roughly three times the spectral efficiency and throughput of a conventional 4-layer setup while maintaining per-user rates under high load. The field results show that software-only massive MIMO on GPUs can meet macro-radio conditions without bespoke silicon.

India Telecom Tariffs & 5G: Data Still Cost-Effective

Indian Telecom Operators Raise Tariffs After Three Years
India has ceded the lowest-tariff crown to Bangladesh and Egypt, yet it still leads on value through generous allowances and low data unit costs. Indian base plans commonly include unlimited voice, whereas Bangladesh and Egypt restrict voice to roughly 100 and 70 minutes respectively at entry level. On data, incremental purchase economics are unusually attractive: an extra Rs 100 typically buys around 26 GB, or about Rs 4 per GB, keeping India among the most affordable data markets globally. Even after adjusting for purchasing power parity, India remains at the affordable end of global tariff rankings.

Vodafone GenAI RIC Accelerates 5G Open RAN rApps

The platform is slated for early 2026 availability and will run primarily on Vodafone’s private Google Cloud Platform environment. Rapid RIC uses GenAI to generate production-grade code from visual designs, enabling radio engineers to turn domain knowledge directly into software without deep AI or ML skills.

Nokia Profit Beat as AI Demand Lifts Optical Networks

Nokia Shifts Focus to AI and Network Infrastructure
Nokia delivered a stronger-than-expected third quarter, with comparable operating profit reaching €435 million against consensus of about €342 million. Group net sales rose 12% to €4.83 billion, above forecasts, driven by Optical Networks and cloud-related demand tied to AI data centers. The stock jumped double digits intraday and added billions in market value, reflecting newfound confidence after a challenging first half. The recovery now is concentrated in network infrastructure rather than mobile RAN, underscoring where customers are actually spending to handle AI-era traffic patterns. Nokia nudged its full-year operating profit outlook to €1.7–2.2 billion, with a reporting change related to scaling down passive venture investments partly in play.

Frequently Asked Questions

What is Open RAN, and why does it matter?
Open RAN disaggregates the radio access network into interoperable components, like the radio unit, distributed unit, and centralized unit, from different vendors instead of one company’s fully integrated, proprietary system, using standardized interfaces defined largely through the O-RAN Alliance. The goal is to reduce vendor lock-in, lower costs through increased competition among a broader pool of vendors, and open the market to smaller, more specialized suppliers who previously couldn’t compete for an entire integrated RAN contract but can now supply individual, standardized components. This represents a genuinely significant shift in an industry historically dominated by a small number of large, established equipment vendors.
Has Open RAN actually been deployed commercially, or is it still mostly trials?
Both descriptions are accurate depending on which operator and market you’re looking at. Dish Network’s greenfield U.S. 5G network covers over 70 percent of the U.S. population using multi-vendor Open RAN running on AWS infrastructure. AT&T has converted more than half of its network traffic to open-capable hardware as part of an ongoing modernization effort, and completed more than half of its radio replacement program as of early 2026. At the same time, integration complexity still makes Open RAN rollouts run 30 to 50 percent longer than traditional, fully integrated RAN deployments according to industry estimates, meaning many operators remain earlier in their transition than the most prominent examples.
Why are governments pushing Open RAN specifically?
Security and supply-chain diversification are major drivers behind government support for Open RAN, distinct from its original cost and innovation motivations. The U.S. NTIA backed Open RAN development with a $1.5 billion funding program, and similar initiatives exist in the UK and EU, largely motivated by reducing reliance on a small number of equipment vendors, including specific geopolitical concerns about Chinese suppliers. Governments view a more diverse, multi-vendor RAN supply chain as both a national security consideration and an economic development opportunity, supporting the growth of domestic and allied-country vendors who can now compete for individual component contracts.
What share of the RAN market does Open RAN actually represent?
Estimates vary by analyst and methodology, but a 2026 Omdia operator survey found that approximately 40 percent of operators surveyed have meaningfully adopted Open RAN principles, either deploying it in production networks or using O-RAN architecture to guide their broader RAN strategy, up significantly from the small, early-pilot adoption rates of just a few years earlier. Separately, the global Open RAN equipment market itself was valued at roughly $5.75 billion in 2025 and is projected to grow substantially through the early 2030s at a compound annual growth rate above 25 percent, even though it still represents a minority share of the overall global RAN equipment market dominated by traditional integrated vendors.
How does Open RAN connect to AI and 6G?
Open RAN’s standardized, programmable interfaces make it considerably easier to integrate AI directly into radio network decision-making, sometimes called AI RAN, since AI applications, known as rApps and xApps, can be developed by third parties and deployed onto the standardized RAN Intelligent Controller framework without needing deep, proprietary integration with a single vendor’s closed system. Operators report measurable spectral efficiency improvements, in the range of 10 to 15 percent in some reported cases, from AI-driven resource allocation enabled by this open architecture. Open RAN’s modularity also makes it a more practical environment for testing new 6G-era concepts incrementally rather than needing to replace an entire integrated system at once.
What are the biggest criticisms or skepticism around Open RAN?
Skepticism around Open RAN generally centers on a few recurring concerns. Performance parity with traditional, fully integrated RAN systems has been a persistent question, since some early multi-vendor deployments have struggled to match the optimization and reliability that comes from a single vendor controlling and tightly integrating every layer of the system. Integration complexity genuinely does extend deployment timelines, raising real questions about whether projected cost savings from increased vendor competition actually offset added integration costs and delays in practice. Some industry voices also argue that Open RAN’s promised vendor diversity and price competition benefits have materialized more slowly than initial enthusiasm suggested.
Who are the main vendors competing in the Open RAN ecosystem?
The Open RAN vendor ecosystem includes both newer, Open RAN-focused specialists and established traditional vendors adapting to the disaggregated model. Newer entrants include companies like Mavenir, Parallel Wireless, and Rakuten Symphony, the latter spun out of Rakuten Mobile’s own early greenfield Open RAN deployment in Japan to sell that technology and approach to other operators globally. Traditional, established vendors including Nokia, Samsung, NEC, and Fujitsu have also adapted their offerings to support Open RAN-compliant, interoperable components rather than purely proprietary integrated systems. Ericsson and Huawei remain dominant in the broader, traditional RAN market but have also engaged with Open RAN initiatives to varying degrees.
What’s the difference between Open RAN and Cloud RAN?
Open RAN and Cloud RAN address related but distinct aspects of RAN modernization. Open RAN specifically refers to using standardized, open interfaces so that radio network components from different vendors can interoperate, addressing vendor lock-in and supply chain diversity. Cloud RAN refers to running RAN software functions on virtualized, cloud-based infrastructure using standard servers rather than dedicated, purpose-built hardware, addressing flexibility and scalability. The two concepts are complementary and often pursued together, since Open RAN’s standardized interfaces make it easier to deploy RAN functions in a Cloud RAN environment from multiple different software vendors, but a network could technically pursue one without fully pursuing the other.
Which industry organizations are playing a prominent role in developing Open RAN?
The main organizations driving the evolution of Open RAN include O-RAN Alliance, O-RAN OSC (Linux Foundation), ONF (SD-RAN project), and Telecom Infra Project (TIP).
O-RAN Alliance focuses on use cases, open RAN architecture, open interfaces, and specifications including testing and integration, while O-RAN OSC and the ONF SD-RAN project provide a software base for some of the components such as RIC. O-RAN ALLIANCE members and contributors have committed to evolving radio access networks around the world. Future RANs will be built on a foundation of virtualized network elements, white-box hardware, and standardized interfaces that fully embrace O-RAN’s core principles of intelligence and openness.
Meanwhile, TIP plays a crucial role in aligning the use cases, deployment requirements, vendors and operators so that first, tests can be conducted in labs and field networks, and subsequently, for the acceleration of commercial deployments. Within TIP, the OpenRAN Project Group defines and builds RAN solutions for 2G,3G, 4G, and 5G RAN networks based on general-purpose vendor-neutral hardware, open interfaces & software. The OpenRAN MoU Group was formed by TIP participants DT, Vodafone, Telefonica, Orange, and TIM, who are working to define and develop OpenRAN solutions that can bring the connectivity that the world needs today, and in decades to come.
