SNR Margin: Signal-to-noise ratio (often abbreviated SNR or S/N)
is a measure used in science and engineering to quantify how much
a signal has been corrupted by noise.
Attenuation: The signal levels to be lower relative to any local noise
and attenuation. This will have the effect of reducing speeds or
causing connection failures.
Output Power: Transmitting power.
Attainable Rate (Kbps): Line rate
Rate(kbps): Date rate.
