teleoperaattori

Teleoperaattori (telecommunications operator) is a company that provides communications services and either owns the networks that transport traffic or purchases capacity from network owners. Operators can be broadly categorized as network operators, which own and manage infrastructure, and service providers, which resell services using wholesale access. In mobile contexts these are known as mobile network operators (MNOs); in fixed networks they are fixed network operators. Some entities also function as mobile virtual network operators (MVNOs), reselling capacity without owning the radio access network.

Teleoperators offer voice calls, messaging, data transmission, Internet access, and value-added services such as television, cloud, or managed IT services. They manage customer onboarding, authentication, provisioning, billing, and support. They may own or lease access networks, maintain core networks, operate data centers, and interconnect with other operators for roaming and for reaching other networks.

Revenue comes from subscriptions, usage charges, device financing, and professional services. Capital expenditure is significant for spectrum licenses, network equipment, towers, and fiber, while operating expenses cover maintenance, energy, and engineering. Wholesale arrangements with other operators and MVNOs enable market reach and competition. Network sharing and modernization, including fiber rollout and 5G deployment, influence pricing and service quality.

Regulation typically covers licensing, spectrum allocation, interconnection, consumer protection, privacy, and net neutrality. Teleoperators operate under licensing conditions and regulator oversight, with mandatory interconnection requirements to ensure universal service and market competition. Markets usually include a small number of large operators alongside many smaller operators and MVNOs, shaping prices, service quality, and innovation.

Technological evolution has driven transitions from 2G/3G to 4G/5G and from copper-based access to fiber, with increasing software-defined networking and virtualization. In Finland, major teleoperators include Telia Finland, Elisa, and DNA, with oversight by regulator Traficom; the market also includes MVNOs and wholesale operators competing on price and service quality.
