Telecommunications Infrastructure

Northern Ireland has a very extensive and modern telecommunications infrastructure, which includes both fixed line and radio networks. The broadband backbone network that provides the high capacity core network connecting major urban centres consists of BT's ADSL Network, NTL's Core Infrastructure, and MCI linkages. In addition there are also radio networks providing both voice (e.g. mobile phone) and data services. (Infrastructure maps can be accessed by clicking on 'Maps' on right hand column.) All towns and cities that are on the backbone network have up to 155 Mbps SDH access capacity. In Belfast, Portadown and Derry up to 622 Mbps is available. In smaller locations served by spurs of the backbone, broadband access may be limited to 2 Mbps over the copper infrastructure. Broadband satellite and wireless services are also available across Northern Ireland. There are also extensive mobile phone networks with 5 major operators delivering services. Northern Ireland has secure, resilient and high capacity international links provided by underground and undersea cables as well as radio and microwave technologies.
