Attenuation is the weakening of signals during transmission.
When the signal becomes weak, it begins to read a 1 for a 0,
and the user may experience communication problems. UTP
faces attenuation around 100 meters. Electromagnetic
interference (EMI) is caused by outside electromagnetic
waves affecting the desired signals, which is not the case
here. Cross talk has nothing to do with the length of the
UTP cable.
