Linz Ag Telekom

What Linz Ag Telekom does

Linz AG Telekom is the regional telecommunications business unit of LINZ STROM GAS WÄRME GmbH, itself owned by the City of Linz, providing B2B connectivity, hosting, and managed-security services to enterprises, public-sector bodies, and institutions across Upper Austria. Its core offering is a 3,000 km fiber-optic network built since 1986, delivering speeds up to 100 Gbit/s, complemented by two EN50600-certified data centers (Linz 2 operational since 2014 and the newly opened Linz 1 in June 2025) and an exclusive private 5G campus network (cityNETWORK 5G) operating over 3.41–3.49 GHz spectrum sourced via LIWEST.

The product stack is modular and marketed under the "city" brand: cityWEB, cityLAN, citySITE, cityHOST, cityPROTECT (including DDoS protection), citySTORAGE, cityBACKUP, cityMON, and Telefonie & Video. These are delivered as integrated, SLA-backed managed services rather than commodity connectivity, with 5G campus offerings explicitly extended to logistics, healthcare, and autonomous-robot use cases. Strategic partnerships with Huawei (5G) and Cisco (Smart City cooperation with the City of Linz, 2018) anchor the technology stack and the municipal go-to-market.

The business model is a recurring-revenue managed-services model: long-term contracts for fiber connectivity, colocation in the two data centers, private 5G campus deployments, and bundled security/monitoring/backup services. Customers cited publicly include Quality Austria, Kreisel Electric, KEBA, AKH Linz, Fabasoft, Dynatrace, World4You, Fischer Brot, Item, Banner, and FH Oberösterreich, spanning industrial, healthcare, software, and education segments. The company is sub-50 employees and operates as a non-listed municipal utility subsidiary, with no public revenue or profit disclosure.

Direct peers

• LIWEST Kabelmedien GmbH: LIWEST is a sister subsidiary within the LINZ AG group, also providing telecommunications services (cable, internet, TV) in the Upper Austria region. It is the entity that acquired the 5G spectrum rights used by Linz Ag Telekom and is directly comparable in regional telco positioning, technologies, and customer base.
• Salzburg AG Telekom: Salzburg AG is a municipal utility-owned telecom operating its own fiber network and data center services in the Salzburg region of Austria. It is structurally and operationally analogous to Linz Ag Telekom — a regional municipal telco with fiber, colo, and B2B services.
• Kapsch BusinessCom: Kapsch BusinessCom is a major Austrian ICT services and managed-services provider with deep fiber relationships to Linz Ag Telekom. It is a long-term partner and partially comparable as a B2B ICT/managed-services peer serving enterprise customers across Austria.
• Energie AG Oberösterreich Telekom: Energie AG is the dominant Upper Austrian energy and infrastructure utility, with telecommunications operations across the same region as Linz Ag Telekom. The two are co-members of the BBI Breitbandinfrastruktur consortium. They effectively compete for the same regional B2B fiber and broadband customers.

Regional players

• Stadtwerke Kapfenberg / CityCom (regional municipal telcos): Regional municipal telcos across Austria (e.g., CityCom, Stadtwerke Klagenfurt, Innsbrucker Kommunalbetriebe) operate similar fiber-plus-managed-services models in other Austrian states. They are structurally comparable peers but do not compete in Upper Austria.

Broad incumbents

• Magenta Telekom: Magenta Telekom (T-Mobile Austria) is a major national carrier offering fiber, mobile, 5G, and B2B ICT services across Austria. It competes head-to-head with Linz Ag Telekom for enterprise connectivity contracts and has a larger national footprint.
• Drei Austria (Hutchison Drei Austria): Drei is one of Austria's three major mobile and fixed-network operators, offering fiber, 5G, and B2B services. Like A1 and Magenta, it competes broadly for Upper Austrian enterprise customers.
• A1 Telekom Austria: A1 is Austria's largest telecommunications incumbent, providing nationwide fiber, mobile, 5G, cloud, and data center services. It competes with Linz Ag Telekom for large enterprise and public-sector contracts in Upper Austria while offering much broader geographic reach and product depth.

Emerging players

• World4You Internet Services GmbH: World4You is an Austrian hosting and server provider listed as a reference customer of Linz Ag Telekom. It is comparable as an Austrian-scale hosting provider using Linz Ag Telekom's data center infrastructure rather than competing directly, but represents the addressable ecosystem for colocation services.
• Fabasoft Cloud: Fabasoft is an Austrian-listed cloud and document management provider headquartered in Linz, listed as a reference customer. It is adjacent through Austrian cloud/hosting overlap (cityHOST competes with managed cloud offerings) and serves a similar Upper Austrian enterprise market.
