B2B
|
Business-to-Business. Electronic transactions between companies.
|
|
B2B e-marketplace
|
Electronic trading platforms on the internet, where companies can sell and/or buy goods or services to/from other companies. These platforms can be operated by a single buyer / seller or by a third party. Many marketplaces are industry-specific. Some marketplaces require registration and membership fees from companies that want to conduct trade on them.

B2C
|
Business-to-Consumer. Electronic business processes between companies and consumers.

Backbone
|
The part of a network that handles the major traffic. It employs the highest-speed transmission paths in the network and may also run the longest distances. Smaller networks are attached to the backbone, and networks that directly connect to the end user or customer are called "access networks."
A backbone can span a geographic area of any size from a single building to an office complex to an entire country. Or, it can be as small as a backplane in a single cabinet.

Backhaul
|
- In wireless network technology, to transmit voice and data traffic from a cell site to a switch, i.e. from a remote site to a central site.
- In satellite technology, to transmit data to a point from which it can be up-linked to a satellite.
- To transmit data to a network backbone.

Bandwidth
|
The physical characteristic of a telecommunications system that indicates the speed at which information can be transferred. In analogue systems, it is measured in cycles per second (Hertz), and in digital systems in binary bits per second. (Bit/s). Usually noted with a K for 1000 bit/s, M for 1 million and G for 1 billion bit/s.

BREW
|
Binary Runtime Environment for Wireless (TM)

Broadband
|
High bandwidth internet access. Broadband is generally defined as the capacity to transfer data at rates of 2Mbit/s (megabits per second) or greater.
|
|
Broadband Wireless Access (BWA) networks.

WiMAX 802.16 technology is expected to enable multimedia applications with wireless connection, and enable networks to have a wireless last-mile solution. IEEE 802.16 covers the fixed and mobile wireless access technologies (known as LMDS) with radio from 2 to 11 GHz. IEEE 802.16d covers the Fixed Wireless Access technologies (known as WIP) with radio below 11 GHz. Frequency bands covered are: 2.4 & 5.8 GHz (both unlicensed) and 2.5 (MMDS) & 3.5 GHz (both licensed). IEEE 802.16e is supposed to add mobility to 802.16d. IEEE 802.16q adds network management facilities for IEEE 802.16d/e. WIP solutions carry packaged data over a high-speed radio link. It can be used as an access technology to connect broadband users, or as a transmission technology between remote network elements.
Way of provisioning local loops without wires: Local loops are the lines between a customer and a telephone company. Such systems are being deployed in Asia and other developing countries to avoid the costs of wires and cables.

Broadcasting
|
A form of unidirectional telecommunication intended for a large number of unidentified users having appropriate receiving facilities, and carried out by means of radio or by cable networks. In English, it should be assumed that “broadcasting by radio waves” is intended where the word “broadcasting” is used without qualification. Examples include sound or television broadcasting, time signals, weather reports to ships, teletext, and news agency bulletins.

|
BSC
|
Base Station Controller. The part of the wireless system’s infrastructure that controls one or multiple cell sites’ radio signals, thus reducing the load on the switch. Performs radio signal management functions for base transceiver stations, managing functions such as frequency assignment and handoff.
|
|
BSS
|
Base Station Subsystem. The system of base station equipment, including Base Transceiver Stations (BTS) and Base Station Controllers (BSC), which is viewed by the Mobile Switching Centre through a standardized interface, as defined in the GSM series of Recommendations, as being the entity responsible for communicating with mobile stations in a certain area.
|
|
BTS
|
Base Transceiver Station. The name for the antenna and radio equipment necessary to provide wireless service in an area. Also called a base station or cell site. Telecommunication over a network of metal or optical cables for distributing sound and video programs, and possibly other signals, to a number of users who are usually identified.. Some users may have access to return channels.
|
|
BWA
|
(Broadband Wireless Access) High-speed wireless access. Typically refers to wireless last mile access to the Internet.
