Radio Frequency Interference

If you use UTP cabling in an installation, take precautions to avoid 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.
To prevent RF interference, avoid the following situations:
Attaching UTP cable to AC power cables
●
Routing UTP cable near antennas, such as an amateur radio antenna
●
Routing UTP cable near equipment that could exhibit RF interference, such as ARC welding
●
equipment
Routing UTP cable near electrical motors that contain coils
●
Routing UTP cable near air conditioner units
●
Routing UTP cable near electrical transformers
●
In areas or applications where these situations cannot be avoided, use fiber optic cabling or shielded
twisted pair cabling (STP).
