Broadband is a method of sending many electronic messages at the same time, using a wide range of frequencies. The two companies said they planned to develop new broadband services for customers in the UK. adj. Term describing the radiation from a source that produces a broad, continuous spectrum of frequencies (contrasted with a laser, which produces a single frequency or very narrow range of frequencies). A typical broadband-light source that can be used for either emission or absorption spectroscopy is a metal filament heated to a high temperature, such as a tungsten lightbulb. Sunlight is also broadband radiation. See also broadband technology
A transmission method that uses a bandwidth greater than a voice-grade channel's, and potentially capable of much higher transmission rates; also called wideband In broadcast transmission, multiple channels access a medium (usually coaxial cable) that has a large bandwidth, using radio-frequency modems Each channel occupies (is modulated to) a different frequency slot on the cable, and is demodulated to its original frequency at the receiving end Cable television is an example
High-speed transmission The term is used to define the speed of communication lines or services and most commonly refers to T1 (1 544 Mbit/s) rates or better, even though the actual rate may be much lower or higher, depending on the application
The provision of multiple channels of information, over a single link which supports high speed through-put of data, typically using some form of frequency or wave-division multiplexing The information could consist of voice, video or computer data See Also: DSL, Mbps Go to top
High-capacity high-speed, transmission channel carried on coaxial or fiber-optic cables with a wider bandwidth than conventional copper telephone lines Broadband channels can carry video, voice, and data simultaneously
A transmission medium that can transmit large volumes of data in many frequencies Use of broadband makes it possible to send quickly large data objects (such as movies, music, and games) using communication lines such as ADSL or CATV It is usually charged at a flat rate and constant Internet access is possible
This transmission medium allows transmission of voice, data, and video simultaneously at rates of 1 544Mbps or higher Broadband transmission media generally can carry multiple channels - each at a different frequency or specific time slot BPS (Bits-Per-Second) A measurement of how fast data is moved from one place to another A 28 8 modem can move 28,800 bits per second
1 Transmission system that multiplexes multiple independent signals onto one cable 2 Telecommunications terminology: Any channel having a bandwidth greater than a voice-grade channel (4 kHz) 3 LAN terminology: A coaxial cable on which analog signaling is used Also called wideband
A transmission medium or channel that has a wider bandwidth than one voice channel (with a carrier wave of a certain modulated frequency) It allows multiple services like voice, data, video, etc to transit over the network
1 A type of communications channel capable of carrying a large portion of the electromagnetic spectrum A broadband channel can accommodate the following media: audio, digital, and television 2 A transmission facility having a bandwidth greater than 20 kHz capable of high speed data transmission 3 An analog transmission technique used with data and video transmissions that provides multiple user channels through frequency-division multiplexing (FDM) See FDM
A service or system requiring transmission channels capable of supporting rates greater than the Integrated Services Digital Network (ISDN) primary rate
Communication channels that are capable of carrying a wide range of frequencies Broadcast television, cable television, microwave, and satellite are examples of broadband technologies These technologies are capable of carrying a great deal of information in a short amount of time, but are more expensive to use than technologies like the telephone, which require less bandwidth (Novak)
Also referred to as wideband A term describing any network that multiplexes multiple, independent network carrier frequencies on to a single cable It allows multiple simultaneous "conversations", since the independent networks operate on different frequencies and do not interfere with each other In LAN terminology, it refers to a system in which multiple channels access a medium, for example co-axial cable, that has a large bandwidth using Radio Frequency (RF) modems This may allow the co-axial cable to carry multiple separate LANs whose transmission is being modulated at different frequencies In cable television (CATV), broadband describes the ability to carry 30 or more TV channels and is synonymous with wideband
A communication network in which the bandwidth can be divided and shared by multiple simultaneous signals (voice, data, video) The network can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies
Denotes transmission facilities capable of handling frequencies required for high-grade communications Broadband infers the use of carrier signals as opposed to direct modulation Characteristically used for simultaneous multi-channel transmission
A term used to compare frequency bandwidth relative to 3 MHz narrowband frequencies Broadband frequencies can transmit more data and at a higher speed than narrowband frequencies In general, typical paging services utilise narrowband frequencies Wireless phones and communication devices use broadband Back to the top
A transmission method in which the networks range of transmission frequencies is divided into separate channels and each channel is used to send a different signal Broadband is often used to send different types of signals simultaneously
A type of transmission that shares the bandwidth of a medium--such as copper or fiber optic cable--to carry more than one signal Broadband facilities have a bandwidth (capacity) greater than a voice grade line of 3 kHz Such a broadband facility--typically coaxial cable--may carry numerous voice, video and data channels simultaneously Each "channel" will take up a different frequency on the cable "Guardbands" (empty spaces) exist between the channels to make sure that each channel does not interfere with its neighbor A coaxial CATV cable is the "classic" broadband channel Simultaneously it carries many TV channels Broadband cables are used in some office LANs But more common are the baseband variety, which have the capacity for one channel only Everything on that cable to be transmitted or received must use that one channel That one channel is very fast, so each device needs only to use that high speed channel for only a little of the time
A transmission medium capable of supporting a wide range of frequencies; can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies; used originally to describe a channel with more bandwidth than a standard 48 KHz voice grade channel
A transmission facility having a bandwidth sufficient to carry multiple voice, video or data channels simultaneously Each channel occupies (is modulated to) a different frequency bandwidth on the transmission medium and is demodulated to its original frequency at the receiving end Channels are separated by ìguardbandsî (empty spaces) to ensure that each channel wonÃt interfere with its neighboring channels This technique is used to provide 50 CATV channels on one coaxial cable
of or relating to or being a communications network in which the bandwidth can be divided and shared by multiple simultaneous signals (as for voice or data or video)
A data transmission technique allowing multiple high-speed signals to share the bandwidth of a single cable via frequency division multiplexing
(1) Transmission facility having a bandwidth greater than 20kHz; capable of high-speed data transmission (2) Analog transmission technique used with data and video transmissions that provides multiple channels for users through frequency division multiplexing
A transmission medium capable of supporting a wide range of frequencies It can carry multiple signals by dividing the total capacity of the medium into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies See also: baseband [Source: RFC1392]
A general term for different types of high-speed, high-bandwidth connections to the Internet, including DSL and cable Back to Top
Telecommunications devices, lines, or technologies that allow communication over a wide band of frequencies, and especially over a range of frequencies divided into multiple independent channels for the simultaneous transmission of different signals. Broadband systems allow voice, data, and video to be broadcast over the same medium at the same time. They may also allow multiple data channels to be broadcast simultaneously
