A broadband network broadly consists of passive infrastructure and active equipment, on top of which the services are delivered:
- The passive infrastructure consisting of physical infrastructure (pipes, masts, ducts, inspection chambers, manholes, cabinets, buildings or entries to buildings, antenna installations, towers and poles) and the broadband cables proper (the transmission medium)
- The active equipment (transponders, routers and switches, radio base stations, control and management servers).
- The actual services that provide value to the end users (internet, telephony, TV, e-health, etc.).
The three network layers are characterised by different technical and economic features, and three main business roles can be identified:
- The physical infrastructure provider (PIP), who owns and maintains the passive infrastructure (characterised by long-term investments and low need for technical know-how), in the backbone or access part of the network;
- The network provider (NP), who operates, and typically owns, the active equipment (characterised by shorter-term investments and high need for technical know-how);
- The service provider (SP), who delivers the broadband services, such as e-health, elder care, TV, internet, phone, video conferencing, entertainment, teleworking, smart monitoring, etc. (characterised by short-term investments and high end-user interaction).

The Broadband planning section helps municipalities and other entities in their planning of successful broadband development projects.
Investment efforts to finance public-private and private-run networks are made in cooperation between private actors who own existing infrastructure, and public authorities.
The basic roles of Physical Infrastructure Provider (PIP), Network Provider (NP) and Service Provider (SP) can be taken by different actors.
Access to the broadband infrastructure is possible via different network nodes on the infrastructure and application level.
Key to successful regional broadband development is a politically-supported plan at local, regional or national level, that combines goals with specific needs and stakeholders.
The action plan details the costs, stakeholders, activities, coordination and monitoring involved in implementing the broadband strategy.
An overview of different wired, wireless and upcoming broadband technologies and a description of their advantages, disadvantages and sustainability.
Choosing the right business model depends on the roles of the market actors in the broadband value chain.
Investment models present interesting involvement opportunities for a public authority that engages in regional broadband development.
The main financing tools for high-speed broadband development projects are own resources, revenue-based financing, loans, equity and grants.
State aid for broadband may be necessary in some places where the market does not provide the necessary infrastructure investment.
A broadband network consists of geographical parts. The topology of a network describes how the different parts of a network are connected. The most relevant topologies for the backbone and area networks are tree topologies, ring topologies and meshed topologies. For the first...
Broadband networks require different infrastructure types based on different logistic, economic or demographic conditions. Use the questions to help choose.
A comparison of broadband technologies presents features of each solution and helps decisions on the best solution for different regions.
