BABT- British Approvals Board for Telecommunications
The UK evaluation and approvals authority for telecoms equipment.
The data transmission capacity of a connection, measured in bits or Bytes of data per second (bps or Bps). Can be thought of in similar terms to the diameter of a pipe conveying water. The amount of bandwidth needed depends on the applications being used - sending or receiving large multimedia files in a short time, or viewing video in real time, needs broadband connectivity.
A fixed radio transmitter/receiver which electronically relays signals to and from mobile voice and data terminals, such as cordless telephones and radio systems.
A term used to express the rating of equipment or a transmission channel, usually in an analogue communication system. The number of pulses that can be transmitted in a second is the baud rate (one baud is equivalent to one pulse per second).
Bluetooth is a wireless technology which allows 'personal area networking' - connection upto 100m between mobile phones, PCs and accessories such as headsets.
BonD - Bandwidth on Demand
The process of combining two or more channels on an ISDN or ADSL line using a multiplexer, with the effect of increasing throughput for bandwidth-hungry applications.
BRI ISDN - Basic Rate Interface ISDN
Provides two channels per physical line, similar to two standard telephone lines. Also known as ISDN2 or ISDN2e, and marketed by BT as BT Highway, HomeHighway and BusinessHighway.
A service or connection allowing large amounts of data to be carried very quickly, and which can split the available bandwidth into multiple channels. Examples of broadband technologies are ADSL, CATV and fixed wireless networks (broadband radio). Previously defined as bandwidth of 2Mbps+ but has become used as a description for services at 128kbps+ - and shared at that!.
