If you use UTP cabling in an installation, take precautions to avoid radio frequency (RF) interference.
RF interference can cause degradation of signal quality, and, in an Ethernet network environment, can cause excessive collisions, loss of link status, or other physical layer problems that can lead to poor performance or loss of communication.
In areas or applications where these situations cannot be avoided, use fiber optic cabling or shielded twisted pair cabling (STP).
