The signal must be sufficiently high for being detected at the destination even in the presence of the noise. Additionally, attenuation of different frequency components is not the same, some frequencies are highly attenuated, and some suffer low attenuation. This reliance of the attenuation of the channel on the frequency of the signal rises the distortion.

Basis for comparison Attenuation Distortion Shape of waveform Does not change Altered Obliteration of the effects Easily removed Harder Relationship Reduction in amplitude, and cause of distortion.

Attenuation occurs in different amounts at different parts of the signal. When a signal travels in space through a medium, it loses some part of its energy. Ready to learn more?

Definition of Attenuation in Networking Attenuation is the loss of signal strength in networking cables or connections. Attenuation can happen with any type of cable or wireless connection, including the following: Copper cables Fiber cables Satellite Radio signals Wireless networks.

Attenuation Versus Amplification While attenuation is the loss of signal strength, amplification boosts the strength of a signal. Continue Reading Below You may also be interested in What Causes Signal or Cable Attenuation?

Listed below are some of the most common causes of signal attenuation. Frequency and Noise All networking and electrical cables give off an electromagnetic frequency within the cable or wireless vicinity. Improving Cables Cables can come in many forms, including copper, fiber, satellite and more. Shortening Distance A network administrator is not only responsible for networking the environment, but to maintain the best efficiencies possible.

Umbrella cell approach in mobile communication. The cell with low traffic speed is called as micro-cells and large high-speed traffic called macro-cells. A hexagonal cell method is on Difference between cell splitting and cell sectoring. Cell splitting is a method of subdividing cell into the smaller sized cell. The parent cell that was originally congested is called as mac Advantages and disadvantages of conduit wiring system. Conduit wiring is a system where the cable is enclosed in metal or some plastic tubes.
