What is the definition of attenuation
Answers
Answer:
Attenuation is a general term that refers to any reduction in the strength of a signal.
Explanation:
Attenuation is a general term that refers to any reduction in the strength of a signal. Attenuation occurs with any type of signal, whether digital or analog. Sometimes called loss, attenuation is a natural consequence of signal transmission over long distances.
In conventional and fiber optic cables, attenuation is specified in terms of the number of decibels per foot, 1,000 feet, kilometer, or mile. The less the attenuation per unit distance, the more efficient the cable.
When it is necessary to transmit signals over long distances via cable, one or more repeaters can be inserted along the length of the cable. The repeaters boost the signal strength to overcome attenuation. This greatly increases the maximum attainable range of communication.
Attenuation in networking
Attenuation in computer networking is the loss of communication signal strength that is measured in decibels (dB). As the rate of attenuation increases, the transmission, such as an email a user is trying to send or a phone call, becomes more distorted.
Attenuation occurs on computer networks because of:
- Range – over longer distances both wired and wireless transmissions gradually dissipate in strength
- Interference – radio interference or physical obstructions, such as walls, dampen communication signals on wireless networks
- Wire size – thinner wires suffer from more attenuation than thicker wires on wired networks
Line attenuation on a digital subscriber line (DSL) network measures signal loss between a DSL provider’s access point and a home, for example. Attenuation is critical on DSL networks because if the line attenuation values are too large, the data rates a household can obtain may be restricted. Values for line attenuation on a DSL connection are typically between 5 dB and 50 dB – the lower the values, the better.
Wi-Fi supports what’s called dynamic rate scaling that enhances the distance at which wireless devices can connect to each other in exchange for lower network performance at the longer distances. Depending on the transmission quality of the line, dynamic rate scaling automatically regulates the connection’s maximum data rate up or down in fixed increments.
