Telecommunications, Northern Ireland

Telecommunications businesses provide the networks and services used to transmit voice, data and other communications over distance. They may supply fixed-line telephone services, mobile connections, broadband internet, business phone systems, leased lines and connectivity for offices or other sites. Some operate network infrastructure, while others resell services or provide communications packages to residential and business customers. Depending on their specialism, businesses in this category may also install and maintain telephone cabling, routers, switches, aerials, mobile signal equipment and private networks. Services can include setting up hosted or cloud-based phone systems, connecting sites, managing business networks and troubleshooting faults. Customers may also obtain handsets, telephone equipment, SIM cards and related accessories.
