Hi Dennis:
UTP can cause the interference. Cat 5 will reduce it, possibly enough to be
imperceptible. The problem lies in where the cables are routed. If the
interference is on the portable there are two possible causes: 1) the
interference is being broadcast or 2) the portable is in an area that creates
interference. This would assume there are a majority of portables not getting
the reported interference.
From your description it appears the interference is being broadcast and is
affecting all portables. I would venture a guess that the network cabling is
affecting the broadcast station. Several ways to reduce or eliminate that
interference.
1. Reroute the network cabling---may or may not reduce the broadcast
interference.
2. Change the network cabling to Cat5 (will reduce or eliminate interference)
or fiber optice (which will eliminate interference)
3. Move the broadcast equipment.
4. Test to make sure the problem is isolated to the network cabling. Shut
down (disconnect) the network cabling that goes through the broadcast station
and see if interference stops. If interference stops, you've determined its
the existing network cabling. If it doesn't stop the interference, then more
than likely there is another cause.
