What represents the loss of a network signal strength measured in decibels (dB) and occurs because the transmissions gradually dissipate in strength over longer distances or radio interference or physical obstructions like walls also impact communication signals?

Attenuation is the one-word answer which is the correct answer for the above question.

Explanation:

Attenuation is a concept which told about the barrier, which is used to stop the signals in the connected network systems. Attenuation can be a form of any type of barrier like weak signals, or because of long-distance.

Following are the example which is in the form of attenuation--

Noise The distance can also be a problem for weak signals. Hacker also disestablished the network signals. The physical objects.

Hence the attenuation can be formed by any of the barriers of signals, like physical obstruction, longer distance, and radio inference.
