By coiling the cable, its balance with respect to noise is improved. Coils
naturally present a high impedance to high frequencies. Coiling cable to make
chokes is a traditional technique, even for coax.

In fact, one of the main differences between Cat5 and Cat3 cable is avoidance
of crosstalk and other interference. Cat5 is much more tightly twisted than
Cat3, and the twists are more tightly controlled to be uniform in distance.

You don't need to go to school for that. Just look at Usenet!
