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).

Déantar iarrachtaí infheistíochta chun líonraí poiblí-príobháideacha agus príobháideacha a mhaoiniú i gcomhar idir gníomhaithe príobháideacha ar leo an bonneagar atá ann cheana, agus údaráis phoiblí.
Is féidir le bardais, cuideachtaí bardasacha, comhfhiontair, agus cuideachtaí príobháideacha a bheith páirteach i gceann amháin, in dhá chéim nó i ngach ceann de thrí chéim d’fhorbairt leathanbhanda.
Is féidir le gníomhaithe éagsúla na róil bhunúsacha atá ag an Soláthraí Bonneagair Fhisiciúil (PIP), ag an Soláthraí Líonra (NP) agus ag an Soláthraí Seirbhíse (SP) a ghlacadh.
Is féidir rochtain a fháil ar an mbonneagar leathanbhanda trí nóid líonra éagsúla ar leibhéal an bhonneagair agus an fheidhmchláir.
Forbhreathnú ar theicneolaíochtaí éagsúla leathanbhanda sreinge, gan sreang agus atá ag teacht aníos agus tuairisc ar na buntáistí, na míbhuntáistí agus an inbhuanaitheacht a bhaineann leo.
The main financing tools for high-speed broadband development projects are own resources, revenue-based financing, loans, equity and grants.
