Telefónica is repurposing part of its historic infrastructure in Spain. The operator has launched the Edge Plan, a rollout aimed at transforming old copper exchanges into a distributed low-latency data center network designed to bring processing and storage closer to where data is generated.
The project aims to establish 17 edge nodes by 2026 across the entire country. The company describes this deployment as the largest of its kind in Europe and links it to three market-changing trends: the need to reduce latencies, the growth of data-driven enterprise services, and the increasing importance of maintaining information within frameworks of digital sovereignty.
From copper exchanges to distributed digital infrastructure
This decision carries an interesting industrial interpretation. For years, copper exchanges were a vital part of the telecommunications network. With the expansion of fiber optics, much of that infrastructure has lost its original purpose. Telefónica now seeks to convert these spaces into highly available edge centers capable of hosting computing and storage capacity closer to businesses, governments, factories, ports, stores, or critical infrastructures.
Edge computing is based on a simple idea: not all data need to travel to a distant data center or a centralized cloud region. Processing locally near the source can reduce response times, avoid unnecessary network hops, decrease external dependencies, and enhance control over information.
This is especially relevant in industrial applications, artificial vision systems, mobile robotics, logistics, predictive maintenance, digital twins, security, connected mobility, or advanced retail. In all these cases, a few milliseconds can be decisive between a viable application and one that is too slow or unreliable.
Telefónica’s planned network will include two nodes in Madrid and one each in Barcelona, Valencia, Seville, Málaga, Palma de Mallorca, Bilbao, A Coruña, Terrassa, Zaragoza, Las Palmas de Gran Canaria, Valladolid, Gijón, Santa Cruz de Tenerife, Santiago de Compostela, and Mérida. This distribution suggests that the goal is not to create a single large hub, but a capillary mesh capable of bringing digital services closer to various parts of the country.

Fiber, 5G SA, and private cloud as the foundation of edge
The deployment relies on two main assets of Telefónica: its fiber-to-the-home (FTTH) network, with over 31 million premises passed in Spain, and its 5G Stand Alone network, available to over 95% of the population based on company data. This combination reduces the number of hops between the customer and the node, optimizes traffic routes, and delivers lower latency than more centralized models.
The 5G SA component is especially significant because it isn’t just about faster mobile networks. Unlike 5G deployments based on 4G core networks, 5G SA enables a more flexible architecture suited for advanced enterprise services, network slicing, low latency, and use cases where connectivity must be integrated with nearby computing.
Telefónica also ties the Edge Plan to its proprietary cloud platforms, TTCP, and open APIs from the Open Gateway project. This layer could be crucial for developers and companies wanting to build services leveraging network capabilities, identity, quality of service, or localization without relying on closed ecosystems.
The underlying message is that the operator aims to go beyond its traditional role as a connectivity provider. With this deployment, Telefónica positions itself as a provider of distributed digital infrastructure: fixed networks, mobile networks, edge centers, private clouds, and third-party APIs. This is a logical evolution in a market where pure connectivity is increasingly limited and value shifts toward services, data, security, automation, and platforms.
Use cases: industry, logistics, mobility, and retail
The company has already begun offering B2B services at several deployed nodes, with two service levels: Basic Edge and Smart Edge. The difference depends on each company’s needs, but the overarching goal is to provide nearby computing capacity for applications that don’t fit well into a remote cloud or isolated local infrastructure.
In Industry 4.0, edge can support mobile robotics, video analysis, predictive maintenance, digitalization of production lines, and traceability. A factory can process sensor and camera data locally, with lower latency and greater control. In logistics and ports, it can help optimize routes, manage fleets, or coordinate operations in real-time. In mobility, it can enhance assisted driving systems, interior perception in trains, or safety analysis.
One of the cited examples is the pilot with CAF in Bilbao, presented as the first European case integrating edge computing and 5G applied to the railway sector. The solution automatically detects train occupancy and the presence of suspicious objects in carriages. It illustrates the kind of application Telefónica envisions: data captured near the user, processed with low latency, used for safety and operational efficiency.
In retail, edge can be used for advanced store analytics, automation, inventory management, customer experience, and local data processing. It can also be relevant for public administrations, healthcare, education, urban security, or municipal services that require local processing and regulatory compliance.
Data sovereignty and competition with centralized cloud
One of Telefónica’s frequently cited arguments is data sovereignty. The term should be used carefully, because hosting data nearby alone does not guarantee full digital sovereignty. Aspects like ownership of infrastructure, jurisdiction, key management, software used, involved providers, operational procedures, and actual audit capacity all matter.
Nevertheless, local edge can strengthen the position of companies and administrations that need to keep certain data within Spain, reduce reliance on external routes, or meet sector-specific requirements. In sensitive applications, it’s not always sensible to send all data to a distant cloud region if it can be processed locally and securely.
The project also benefits from European support. According to published information, it’s driven by the European Commission under an Important Project of Common European Interest (IPCEI) and backed by the Recovery, Transformation, and Resilience Plan. This context underscores the strategic importance of the deployment: it’s not just a commercial initiative by Telefónica but part of the broader European debate on digital autonomy, critical infrastructure, and technological sovereignty.
The major challenge will be adoption. Edge computing has promised much for years, but its actual deployment depends on solid use cases, reasonable prices, simple integration, an ecosystem of partners, and companies’ ability to redesign applications. Not all workloads require edge. Many will still perform better in centralized cloud or traditional local infrastructures. The key will be identifying where low latency, proximity, data control, and 5G connectivity deliver measurable value.
Telefónica starts with an advantage: it already has the network, locations, coverage reach, and relationships with companies and administrations. If it can turn these assets into an open, interoperable, and easy-to-use platform, the Edge Plan could establish Spain as a prominent player within Europe’s distributed infrastructure map.
Edge computing will not replace the cloud; it will complement it. The coming architecture will be inherently hybrid: massive cloud regions for large-scale workloads, private data centers for critical processes, edge nodes for low latency, and intelligent devices at the network’s edge. Telefónica aims to occupy that middle layer—where the network stops being just transportation and starts offering nearby processing capabilities.
