TermDefinition
BackboneMain trunk at the uppermost level of a hierarchic network. The backbone may also connect several local networks (LANs).
Broadband Power LineTo-the-home powerline communications — essentially DSL over mains cables
BandwidthA measure of the rate at which digital bits can be transported from one place to another; also: frequency span over which useful signals can be transmitted.
(de: Bandbreite, es: Ancho de banda)
Device Language Message (DLM / DLMS)A draft protocol for remote-readable electricity meters
EarthSet of interconnected conducting elements that will unify the electrical potential to a single value
EarthingAct of connecting to earth.
(de: Erden, es: poner a tierra)
FieldSpatial distribution of magnitude, direction and sense of magnetic or electrical effects radiated from a given source.
(de: Feld, es: campo)
Field StrengthMagnitude of the field vector at a given point.
(de: Feldstärke, es: intensidad de campo)
FilterA device for the selective offer of a low impedance path for signals of a given frequency.
(es: filtro)
FrequencyRate at which a physical parameter is changing per unit time, cycles per second [c/s] or Hertz [Hz].
(de: Frequenz, es: frecuencia)
High Speed Circuit Switched Data (HSCSD)A method for higher data transmission in existing networks by compression and channel packing (bandwidth 9.6-43.2 kbit/s).
HomeplugIndustry alliance and de facto standard for In-Home powerline networks.
ImpedanceAggregate opposition to be overcome when transmitting energy and signals of alternating current or pulses.
(es: impedancia)
InterferenceUnwanted effect of one field over another.
(de: Störung, es: interferencia)
Internet ProtocolThe standard protocol for transmission of data packets on the Internet.
M-BusAn interface for remote-readable electricity meters.
MainsThe part of the electrical energy distribution system that delivers energy to individual customers.
(de: Stromnetz, es: red de alimentación)
MultiplexerFunctional unit managing a transmission channel or a passive medium in such a way that several station pairs can communicate simultaneously on this unit.
NoiseSignals without a specific meaning.
(de: Rauschen, es: ruido)
PowerEnergy per unit time [W] Watt.
(de: Leistung, es: potencia)
Power LineSystem of cables through which electrical energy is made available.
(de: Energienetz, es: línea eléctrica)
RadiationManner in which electromagnetic and electrical fields propagate from an electrical source.
(es: radiación)
RouterSystem connecting physically different networks using the same transmission protocol. They route data packets, for example, from LANs to the Internet and identify optimum transmission routes for data traffic.
(es: ingeniería inversa)
Screening coefficientExpression of how much the signal placed on the inner conductor of a coaxial cable is protected from outside electromagnetic fields by the shield; in [dB].
(de: Schirmeffekt, es: coeficiente de blindaje)
TelecommunicationTransportation of a signal from one place to another; traditionally understood to be carried out over a physical line.
(de: Übertragung, es: telecomunicación)
Three Pot BankThree transformers on a powerline pole.
TransformerElectrical stationary machine that allows to change the values of voltage/current at which electrical energy is delivered.
(de: Transformator, es: transformador)
Twisted PairPair of copper telephone lines.
(es: Par telefónico / Par trenzado)
Universal Powerline BusA Home Automation technology using Powerline Communications. Possible successor to X-10, CEBUS and LONWORKS.
