Line Attenuation

Line Attenuation
In gerneral, attenuation is the loss of signal over distance. Unfortunately, dB loss is not just dependent on distance. It also depends on cable type and gauge (which can differ over the length of the cable), the number and location other connection points on the cable.
•20bB. and below = Outstanding
•20dB-30dB. = Excellent
•30dB-40dB. = Very Good
•40dB-50dB. = Good
•50dB-60dB. = Poor and may experience connectivity issues
•60dB. and above = Bad and will experience connectivity issues
Line attenuation also affects your speed.
•75 dB+: Out of range for broadband
•60-75 dB: max speed up to 512kbps
•43-60dB: max speed up to 1Mbps
•0-42dB: speed up to 2Mbps+

SNR means Signal to Noise Ratio

SNR means Signal to Noise Ratio.

Simply put divide the Signal value by Noise Value and you get SNR. You need high SNR for a stable connection. In general, a higher signal to noise ratio will result in less errors.
•6bB. or below = Bad and will experience no line synchronisation and frequent disconnections
•7dB-10dB. = Fair but does not leave much room for variances in conditions.
•11dB-20dB. = Good with little or no disconnection problems
•20dB-28dB. = Excellent
•29dB. or above = Outstanding
