Encyclopedia > Transmission (telecommunications)

In telecommunications, transmission is the act of transmitting electrical messages (and the associated phenomena of radiant energy that passes through media). Messages can be a series of data units, such as binary digits, or groups of those, variously called frames, blocks. Telecommunication is the transmission of signals over a distance for the purpose of communication. ... Message in its most general meaning is an object of communication. ... Radiant energy is the energy of electromagnetic waves. ... Electrical conduction is the movement of electrically charged particles through matter. ... Data is the plural of datum. ... This article is about the unit of information, see Bit (disambiguation) for other meanings. ... In telecommunications, a frame is a packet which has been encoded for transmission over a particular link. ... In telecommunication, the term block has the following meanings: A group of bits or digits that is transmitted as a unit and that may be encoded for error-control purposes. ...


Transmission can be split up into two parts:

  1. The dispatching by a sender, for reception elsewhere, of a signal, message, or any form of information.
  2. The propagation of a signal by any means, such as by telegraph, telephone, radio, television, or facsimile via any medium, such as wire, coaxial cable, microwave, optical fiber, or radio frequency.

In general information theory transmission is taken to mean the complete process of communication of information via a channel. A source is one of the components of communication and information processing. ... The receiver in information theory is the receiving end of a communication channel (in particular the binary symmetric channel) in information theory. ... In telecommunication, signalling (or signaling) has the following meanings: The use of signals for controlling communications. ... Information as a concept bears a diversity of meanings, from everyday usage to technical settings. ... Radio propagation is a term used to explain how radio waves behave when they are transmitted, or are propagated from one point on the Earth to another. ... Telegraphy (from the Greek words tele = far away and grapho = write) is the long distance transmission of written messages without physical transport of letters, originally over wire. ... An old rotary telephone This article is about telephone technology. ... This page is a candidate to be moved to Wiktionary. ... A transmission medium is any material substance, such as fiber-optic cable, twisted-wire pair, coaxial cable, dielectric-slab waveguide, water, or air, that can be used for the propagation of signals, usually in the form of modulated radio, light, or acoustic waves, from one point to another. ... A wire is a single, usually cylindrical, elongated strand of drawn metal. ... Radio-grade flexible coaxial cable. ... Microwave image of 3C353 galaxy at 8. ... A bundle of optical fibers. ... Rough plot of Earths atmospheric transmittance (or opacity) to various wavelengths of electromagnetic radiation, including radio waves. ... To meet Wikipedias quality standards, this article or section may require cleanup. ... Communication is the process of sending information to oneself or another entity, usually via a language. ... In coding theory, a binary symmetric channel (or BSC) is an idealized model of a communications channel that sends bits. ...


See also: communication channel, Byte A Communications channel (or channel for short), models the medium through which information is transmitted from a sender (or transmitter) to a receiver. ... A byte is commonly used as a unit of storage measurement in computers, regardless of the type of data being stored. ...
