Data transmission terminology

This article is near Internet connectivity and telecommunication signalling methods and high-speed Net. For article where broadband is found, encounter Internet access. For book, come across Broad Band.

In telecommunications, broadband is wide bandwidth data manual which transports multiple signals at a broad range of frequencies and Net traffic types, that enables messages to be sent simultaneously, used in fast internet connections. The medium can be coaxial cable, optical cobweb, wireless Internet (radio), twisted pair or satellite.

In the context of Cyberspace access, broadband is used to mean any high-speed Internet access that is always on and faster than dial-upward access over traditional analog or ISDN PSTN services.

Overview [edit]

Unlike criteria for "broad" accept been applied in different contexts and at different times. Its origin is in physics, acoustics, and radio systems applied science, where it had been used with a meaning similar to "wideband",[ane] [ii] or in the context of audio noise reduction systems, where it indicated a single-ring rather than a multiple-audio-band system design of the compander. Later, with the advent of digital telecommunication, the term was mainly used for transmission over multiple channels. Whereas a passband bespeak is besides modulated and so that it occupies higher frequencies (compared to a baseband signal which is leap to the everyman end of the spectrum, see line coding), it is nonetheless occupying a unmarried channel. The central difference is that what is typically considered a broadband point in this sense is a bespeak that occupies multiple (non-masking, orthogonal) passbands, thus allowing for much college throughput over a single medium but with boosted complexity in the transmitter/receiver circuitry.

The term became popularized through the 1990s as a marketing term for Cyberspace admission that was faster than dial-upward access (dial-up being typically limited to a maximum of 56 kbit/due south). This pregnant is only distantly related to its original technical significant.

Since 1999, broadband has been a cistron in public policy. In that year, at the Globe Trade Organization Biannual Conference called "Fiscal Solutions to Digital Divide" in Seattle, the term "Meaningful Broadband" was introduced to the world leaders leading to the activation of a movement to shut digital separate. Cardinal aspects of this movement is to suggest that the equitable distribution of broadband is a fundamental human right.[3]

Broadband technologies [edit]

Telecommunication [edit]

In telecommunications, a broadband signalling method is ane that handles a wide band of frequencies. "Broadband" is a relative term, understood according to its context. The wider (or broader) the bandwidth of a aqueduct, the greater the data-carrying capacity, given the same channel quality.

In radio, for example, a very narrow band will carry Morse lawmaking, a broader ring will conduct voice communication, and a notwithstanding broader ring will carry music without losing the high audio frequencies required for realistic sound reproduction. This broad band is ofttimes divided into channels or "frequency bins" using passband techniques to let frequency-division multiplexing instead of sending a higher-quality signal.

In information communications, a 56k modem will transmit a data rate of 56 kilobits per second (kbit/s) over a iv-kilohertz-wide telephone line (narrowband or voiceband). In the late 1980s, the Broadband Integrated Services Digital Network (B-ISDN) used the term to refer to a broad range of bit rates, independent of physical modulation details.[iv] The various forms of digital subscriber line (DSL) services are broadband in the sense that digital information is sent over multiple channels. Each channel is at higher frequency than the baseband phonation channel, so it can support plain old telephone service on a single pair of wires at the same fourth dimension.[5] Withal, when that same line is converted to a non-loaded twisted-pair wire (no telephone filters), information technology becomes hundreds of kilohertz wide (broadband) and can carry up to 100 megabits per second using very-high-bit-rate digital subscriber line (VDSL or VHDSL) techniques.[vi]

Computer networks [edit]

Many computer networks use a elementary line lawmaking to transmit one type of signal using a medium'south full bandwidth using its baseband (from aught through the highest frequency needed). About versions of the popular Ethernet family are given names such equally the original 1980s 10BASE5 to signal this. Networks that use cablevision modems on standard cable television infrastructure are called broadband to bespeak the wide range of frequencies that can include multiple data users as well as traditional tv channels on the same cable. Broadband systems unremarkably use a different radio frequency modulated past the data signal for each band.[7]

The full bandwidth of the medium is larger than the bandwidth of any channel.[viii]

The 10BROAD36 broadband variant of Ethernet was standardized past 1985, simply was not commercially successful.[9] [x]

The DOCSIS standard became available to consumers in the late 1990s, to provide Internet access to cablevision idiot box residential customers. Matters were farther dislocated past the fact that the 10PASS-TS standard for Ethernet ratified in 2008 used DSL technology, and both cable and DSL modems frequently have Ethernet connectors on them.

Boob tube and video [edit]

A television antenna may be described as "broadband" because it is capable of receiving a broad range of channels, while east.g. a low-VHF antenna is "narrowband" since information technology receives only i to 5 channels. The U.S. federal standard FS-1037C defines "broadband" as a synonym for wideband.[xi] "Broadband" in analog video distribution is traditionally used to refer to systems such as cable television, where the individual channels are modulated on carriers at fixed frequencies.[12] In this context, baseband is the term's antonym, referring to a unmarried channel of analog video, typically in composite class with divide baseband sound.[13] The deed of demodulating converts broadband video to baseband video. Fiber optic allows the signal to be transmitted farther without being repeated. Cable companies apply a hybrid system using fiber to transmit the signal to neighborhoods and then changes the bespeak from light to radio frequency to be transmitted over coaxial cable to homes. Doing so reduces the use of having multiple caput ends. A head terminate gathers all the information from the local cable networks and movie channels and and so feeds the information into the system.

Even so, "broadband video" in the context of streaming Internet video has come up to hateful video files that accept scrap-rates high plenty to crave broadband Internet access for viewing. "Broadband video" is too sometimes used to depict IPTV Video on demand.[xiv]

Alternative technologies [edit]

Power lines have also been used for various types of information communication. Although some systems for remote command are based on narrowband signaling, modernistic high-speed systems use broadband signaling to accomplish very high data rates. One case is the ITU-T G.hn standard, which provides a way to create a local area network upward to 1 Gigabit/s (which is considered loftier-speed equally of 2014) using existing dwelling house business organization and habitation wiring (including power lines, simply also telephone lines and coaxial cables).

In 2014, researchers at Korea Advanced Institute of Scientific discipline and Technology made developments on the creation of ultra-shallow broadband optical instruments.[fifteen]

Internet broadband [edit]

In the context of Internet access, the term "broadband" is used loosely to mean "access that is always on and faster than the traditional punch-up access".[16] [17]

A range of more precise definitions of speed take been prescribed at times, including:

  • "Greater than the principal charge per unit" (which ranged from about 1.v to 2 Mbit/s) —CCITT in "broadband service" in 1988.[xviii]
  • "Internet access that is always on and faster than the traditional dial-up access"[16] —U.s. National Broadband Program of 2009[19]
  • 4 Mbit/south downstream, 1 Mbit/s upstream —Federal Communications Commission (FCC), 2010[xx]
  • 25 Mbit/southward downstream, three Mbit/south upstream —FCC, 2015[20]
  • 50 Mbit/due south downstream, 10 Mbit/s upstream —Canadian Radio-television and Telecommunication Commission (CRTC)[21]

Broadband Net service in the United States was finer treated or managed as a public utility by cyberspace neutrality rules[22] [23] [24] [25] [26] until existence overturned by the FCC in Dec, 2017.[27]

Speed qualifiers [edit]

A number of national and international regulators categorize broadband connections according to upload and download speeds, stated in Mbps (megabits per second).

Term Regulator(southward) Min Download Speed (Mbit/due south) Min Upload Speed (Mbit/south) Notes
Full fibre / FFTP/H[28] Ofcom 100 i
Gigabit[29] EU 1000 1
Ultrafast[xxx] Ofcom 300 1
Ultra-fast / Gfast[31] [29] European union, UK Government 100 i
Fast[29] EU thirty
Superfast[32] Ofcom 30 one
Superfast[32] United kingdom of great britain and northern ireland Government 24 1
Broadband[33] FCC 25 3
Broadband[34] Ofcom 10 ane
Broadband[35] CRTC 50 10

In Commonwealth of australia, the Australian Competition & Consumer Commission also requires Internet Service Providers to quote speed during nighttime time and decorated hours [36]

Global bandwidth concentration [edit]

Global bandwidth concentration: three countries have almost 50% betwixt them; 10 countries about 75%.[37]

Bandwidth has historically been very unequally distributed worldwide, with increasing concentration in the digital historic period. Historically but ten countries have hosted 70–75 % of the global telecommunication chapters (see pie-chart Figure on the right).[37] In 2014, only three countries (China, The states, Japan) host 50% of the globally installed telecommunications bandwidth potential. The U.S. lost its global leadership in terms of installed bandwidth in 2011, existence replaced past China, which hosts more than than twice every bit much national bandwidth potential in 2014 (29% versus 13% of the global total).[37]
