- This article is about the specific technical term. For the end user Internet access method see Broadband Internet access.
Broadband in general refers to data transmission where multiple pieces of data are sent broadband telephone simultaneously to low cost broadband increase the effective rate broadband uk of transmission. In network engineering this term is used for methods satellite broadband internet where aol broadband two or more signals broadband share a medium.
Various broadband internet service forms broadband wireless of [[Digital Subscriber Line]] service are broadband in the sense that digital information is sent over one channel and voice over another channel sharing a single pair broadband phone cable of wires. Analog modems operating at speeds greater than 600 bit/s are technically broadband. They obtain higher effective vsat broadband transmission rates by using multiple broadband phone channels with the rate on each channel limited to 600 baud. broadband broadband satellite internet isp For example, a 2400 bit/s modem uses four 600 baud channels (see baud). This is in contrast to a baseband transmission where one free broadband hardware type broadband for business of signal broadband satelite internet uses a medium's full bandwidth such as 100BASE-T Ethernet.
Multiplexing
Communications may utilise a number of distinct physical broadband tv channels wireless broadband simultaneously; broadband adsl atlantic broadband this is multiplexing for multiple access. broadband providers Such channels may be distinguished by being broadband phone services separated from each broadband test other in time (time division multiplexing or TDMA), in carrier frequency (frequency division multiplexing (FDMA) or wavelength division multiplexing bt broadband satellite broadband verizon wireless broadband (WDM)), or in access method (code division multiplexing or CDMA). Each channel that takes part in such a multiplexing exercise is by definition narrowband (because it is not utilising the whole bandwidth of the broadband service providers medium), whereas the whole set of channels taken together and utilised for the same communication download file dial click broadband could be described as broadband.
BT is a major player broadband services in this market
Confusing usage
While many lower rate forms of data transmission, such as analog modems above 600 bit/s, are broadband, broadband has been more closely associated with higher data rate forms of broadband data transmission such as T-carrier and Digital Subscriber Lines. Therefore, the word "broadband" has also come broadband internet to mean a relatively high rate, while the term "narrowband" is used to mean a relatively low rate. It is now broadband zoomtown broadband speed quite common to hear a broadband method such as a 9600 bit/s modem broadband residential described broadband telephone service as "narrowband", while cheap broadband broadband internet providers a high rate baseband transmission broadband home such broadband internet rural broadband provider as 10BASE-T is described broadband satellite as "broadband". The International Telecommunication broadband router Union Standardization Sector (ITU-T) recommendation broadband phone service I.113 has defined broadband as a transmission capacity that is faster verizon broadband than primary rate ISDN, at 1.5 to 2 Mbit/s. However speeds of 256 kbit/s and greater are commonly marketed as "broadband" and this convention is broadband what is broadband provider held to by policy makers and ISPs alike. broadband service See Broadband Internet access. Note: The term "narrowband" is also used to mean the opposite of "wideband" instead of the opposite of "broadband".

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
