Spain Digital 2026: The Real State of 5G and Fiber Rollout According to the Ministry of Development

The Spain Digital 2026 agenda constitutes the strategic roadmap for the country's digital transformation, updating the initial 2025 objectives to align with European Union priorities. Its implementation critically depends on the execution of the Recovery, Transformation, and Resilience Plan, which finances the majority of investments in connectivity and digital infrastructure.

Component 15 of the Plan, dedicated to digital connectivity and 5G rollout, mobilizes 15 billion euros to guarantee access to very high-speed internet across the national territory. The recent extension of deadlines until 2026 reflects the logistical and administrative complexity of bringing these networks to rural and remote areas, where commercial profitability is limited.

The deployment of 5G networks requires the efficient allocation of radio spectrum, particularly in the 3.5 GHz band, identified as a priority at the European level. In 2021, the Ministry awarded the last 20 MHz available in this band to Telefónica and Orange, at a starting price of 21 million euros each.

Following these awards, the distribution of spectrum in the 3.5 GHz band was established with Orange as the operator with the largest allocation (110 MHz), followed by Telefónica (100 MHz), Vodafone (90 MHz), and MásMóvil (80 MHz). This reorganization seeks to optimize frequency usage through contiguous blocks, facilitating technical efficiency in the deployment of 5G technology.

Fiber to the home (FTTH) has consolidated itself as the predominant technology in Spanish fixed broadband. According to data from March 2026 published by the CNMC, FTTH lines exceeded 18 million accesses, representing the vast majority of the 19.70 million total fixed broadband lines.

The growth of FTTH has been sustained in recent years, with accelerated expansion in smaller municipalities. In 2020, more than 80% of newly installed accesses were deployed in municipalities with fewer than 100,000 inhabitants, reducing the territorial digital divide. Market share is concentrated in four main operators, which control more than 95% of fixed broadband lines.

The Government has extended the execution and justification deadlines for the ÚNICO-Broadband and ÚNICO 5G Backhaul programs to provide more margin to the awarded companies. Projects can be executed until April 15, 2026, and justified until May 16, 2026, with the possibility of an exceptional extension until June 30, 2026.

This extension responds to the need to complete coverage in areas where 4G mobile service with a minimum quality of 50 Mbps did not exist. The ÚNICO 5G Active Networks program, regulated by Order ETD/685/2023, finances the provision of active equipment and auxiliary infrastructure to guarantee mobile connectivity in these underserved areas.

In parallel with terrestrial deployment, satellite internet connections have experienced significant growth in Spain. According to a CNMC report from September 2026, satellite accesses have multiplied by ten in three years, going from 10,000 at the end of 2022 to nearly 100,000 at the end of 2025.

Although they represent only 0.5% of the total fixed broadband connections, satellite services play a relevant role in rural and remote areas where fiber optics is not economically viable. The growth is driven by new constellations of satellites in low Earth orbit (LEO), which offer improved performance compared to traditional geostationary solutions.

It is fundamental to distinguish between regulatory milestones confirmed by official sources and market projections or emerging technologies. Coverage data, spectrum licenses, and the execution of Recovery Plan funds are administrative facts verifiable through CNMC reports and Ministry publications.

Technologies such as edge computing, technological sovereignty, or specific 5G applications in vertical sectors (tourism, security, connected vehicle) are in development or piloting phases, with specific aid calls like the UNICO 5G Sectorial program. These initiatives complement, but do not replace, the basic connectivity infrastructure that constitutes the core of the Spain Digital 2026 agenda.
