Avoiding Co-Channel Interference
Operating more than three systems (ZeroWire pairs) in one area may result in co-channel interference. In
order to avoid the potential of co-channel interference, a 75 foot (23 m) separation should be maintained
between any two ZeroWire pairs that are operating on the same channel. The 75 foot (23 m) separation is a
general guideline, the actual separation required to avoid co-channel interference may vary greatly. Some
of the many factors that can affect how well a particular RF channel is isolated include:
1) The thickness and material of the room walls.
2) The opening and closing of room doors.
3) The room’s ceiling structure and the materials used in its construction.
In cases where it is not possible to maintain adequate separation, it may not be possible to operate a
ZeroWire pair simultaneously in every room of the facility. A room layout similar to the that shown in
image
1 below is a good example. Due to the rooms being so close together, running one pair in each
room simultaneously is not possible.
However, for a room layout like the one shown in image
2 below, one pair can be operated in each
room simultaneously, as long as the appropriate settings are used. In this scenario, if the 3 Channel
selection setting is used, each pair will scan for an available channel upon power up, which ensures
adequate channel separation. In this scenario, a 75 foot (23 m) separation can be maintained for each
specific RF channel.
Note:
Operation of a ZeroWire system for room to room communications is not recommended and not
supported.
