Attenuation in data communication is the weakening of a signal over distance. When data signals travel through wires or air, they get weaker. This weakening is called attenuation.
Attenuation is measured in decibels (dB). A higher dB value indicates a greater signal loss. This weakening can cause errors in data transmission and limit the distance signals can travel without amplification.
Network engineers use devices like amplifiers and repeaters to counteract attenuation to boost signals. They also choose cables with lower attenuation rates for longer distances.
