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.
