A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver. It is an equation giving the received power from the transmitter power, after the attenuation of the transmitted signal due to propagation, as well as the antenna gains and feedline and other losses, and amplification of the signal in the receiver or any repeaters it passes through. A link budget is a design aid, calculated during the design of a communication system to determine the received power, to ensure that the information is received intelligibly with an adequate signal-to-noise ratio. Randomly varying channel gains such a

rdfs:comment	Die Leistungsübertragungsbilanz (englisch link budget) ist in der Nachrichtentechnik ein Maß für die Qualität eines Übertragungskanals. Die Bilanz wird in der Einheit Bel (mit positiven oder negativen Werten) angegeben und in einem einfachen Modell durch die Addition der Sendeleistung, der Empfängerempfindlichkeit, des Antennengewinns und der Freiraumdämpfung berechnet. Ein Teil der Leistungsübertragungsbilanz wird durch die Friis-Übertragungsgleichung gebildet. (de) Le bilan de liaison est un calcul par étapes permettant de déterminer la qualité d’une liaison. Les détails varient selon la nature du média, hertzien, ligne, fibre optique, et le type de signaux et de modulation, mais le principe est le même. C'est le calcul global qui relie tous les domaines : radioélectricité, traitement du signal, protocoles, etc. (fr) In telecomunicazioni il termine bilancio di collegamento (in inglese link budget) indica una relazione formale che stabilisce il bilancio di potenza di un sistema di telecomunicazione tra la potenza ricevuta dal ricevitore in funzione di quella emessa dall'apparato trasmittente e che include tutti i fattori di amplificazione e dissipativi lungo il canale di comunicazione. (it) 链路预算（link budget），是在一个通信系统中对发送端、通信链路、传播环境（大气、同轴电缆、波导、光纤等）和接收端中所有增益和衰减的核算。其通常用来估算信号能成功从发射端传送到接收端之间的最远距离。 (zh) El balanç de l'enllaç (en anglès link budget), en electrònica, és la suma de tots els guanys i pèrdues des del transmissor, a través del mitjà (espai, cable, fibra, etc) i fins al receptor en un sistema de telecomunicacions. Un balanç d'enllaç simple seria: Potència rebuda (dB) = Potència tramesa (dB) + Guanys (dB) - Pèrdues (dB) Un balanç d'enllaç més complet (tenint en compte antenes i altres pèrdues): (ca) A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver.
