Broadband Delivery Programme
Annex A: Glossary
4G – Fourth Generation of mobile services.
Broadband – The term used to describe a wide range of technologies that allow high-speed, always-on access to the Internet. This is most often delivered via a connection through a telephone line or cable service, but can also be delivered using wireless and satellite connections. A potential access speed of less than 512 Kbps is deemed not to be broadband.
Broadband Stakeholder Group (BSG) – Website: www.broadbanduk.org. ERDF – European Regional Development Fund. Fibre based solutions – see FTTC, FTTH and FTTB.
FTTC (Fibre-to-the-cabinet) – Access network consisting of optical fibre extending from the access node to the street cabinet. The street cabinet is usually located only a few hundred metres from subscriber premises. The remaining segment of the access network from the cabinet to the customer is usually a copper pair but could use another technology, such as wireless.
FTTH (Fibre-to-the-home) – A form of fibre optic communication delivered in which the optical signal reaches the end user‟s living or office space.
FTTB (Fibre-to-the-building) – A form of fibre-optic communications delivery in which an optical fibre is run directly onto the customers‟ premises.
GHz – GigaHertz, a measurement of frequency in radio spectrum.
LTE – (Long Term Evolution). Part of the development of 4G mobile systems that started with 2G and 3G networks.
Mbps – Megabits per second. MHz – MegaHertz – a measurement of frequency in radio spectrum.
Mobile broadband – Various types of wireless high-speed internet access through a portable modem, telephone or other device.
Not spot – A geographic postcode area where Customers do not have access to fixed line or wireless broadband.
Ofcom – The Office for Communications. PSN – Public Sector Network. RDPE – Rural Development Programme for England
Slow spot – A geographic postcode area where Customers have access to fixed line or wireless broadband at access speeds below 2Mbps.
SME – Small and Medium Enterprise.
Standard Broadband – BDUK has defined standard broadband as a service available at the edge of the network that allows a quality home working experience, for which a headline access speed of 2Mbps can be used as a proxy.
Sub-Loop Unbundling – The process by which a sub-section of part of the local loop in the access network is unbundled and allows other operators to interconnect with the local access network at a point between an incumbent‟s site and the end user.
Superfast Broadband – BDUK has defined Superfast Broadband as having a potential headline access speed of at least 20Mbps, with no upper limit. Typically, at a wholesale level, the underlying capability can be measured in gigabits. The retail market then takes this capability and delivers affordable propositions.
